Actualités Watchman

You probably know you should move more, sleep better, and eat cleaner — but the gap between knowing and doing feels enormous. Two large studies now show that the gap is much smaller than you think. The first, published in The Lancet and drawing on wearable-device data from more than 135,000 adults, found that remarkably small increases in daily movement — and modest reductions in sitting — were associated with meaningful drops in mortality.1

The second, published in eClinicalMedicine and tracking 59,078 U.K. Biobank participants, went further by measuring what happens when you combine tiny upgrades across sleep, physical activity, and diet simultaneously.2 The combined approach proved far more powerful than improving any single habit alone. Cardiovascular disease, Type 2 diabetes, and dementia continue to shorten both lifespan and healthspan for millions.

These conditions don’t appear overnight. They build through years of accumulated metabolic stress — stress that even small daily habits either feed or reverse. The takeaway from both studies is the same: you don’t need an extreme regimen. You need micro-improvements that stack — small daily deposits into a health account that compounds over years.

5 Minutes That Shift Survival Odds

For The Lancet study, researchers examined data from adults across Norway, Sweden, the U.S., and the U.K. Biobank. Instead of relying on memory-based questionnaires, they used wearable devices to measure real movement and sitting time.

They then modeled a simple question: how many deaths could be prevented if people moved just five to 10 more minutes per day or sat 30 to 60 minutes less? This isn’t about marathon training. It’s about realistic, bite-sized changes that fit into your current routine. Participants were followed for about eight years on average.

Just five extra minutes of brisk movement per day was linked to preventing up to 1 in 10 deaths among most adults — and about 1 in 17 among even the least active. Cutting sedentary time by 30 minutes per day was associated with preventing about 7% of deaths in most adults and about 3% in the most sedentary group. That means small shifts across a population translate into thousands of lives.

• Returns scaled with effort — Ten minutes of daily moderate-to-vigorous activity was linked to about a 15% reduction in mortality for most adults and 9% for the least active — roughly 50% more benefit for double the time.
Moderate intensity includes brisk walking at about 3 miles per hour. Vigorous intensity includes activities that make you breathe hard. A one-hour reduction in sedentary time was linked to a 13% reduction in deaths in the majority of adults and 6% among the least active group.
• The greatest gains showed up in those who moved the least — The study highlighted that “the greatest benefit was observed if the least active 20% of the population increased their activity by five minutes per day.”3 So, if you’re currently doing almost no brisk movement, you stand to gain the most from a tiny upgrade. That creates a powerful opportunity.
• Sedentary time mattered independently of exercise — Many adults in the study spent 10 to 12 hours per day sedentary. The researchers showed that even trimming 30 minutes off that sitting time had measurable associations with reduced mortality. Sedentary time means hours spent sitting or lying down awake. Long, unbroken sitting slows muscle activity, which affects how your body handles blood sugar and fats. Breaking that pattern resets muscle contractions and circulation.
• Moderate-to-vigorous activity improves insulin sensitivity — This means your cells respond better to insulin and clear glucose from your bloodstream more efficiently. That lowers strain on your pancreas and reduces metabolic stress.
Physical activity also improves mitochondrial function. Mitochondria are the energy generators inside your cells. Think of mitochondria like batteries that recharge through use. When you move regularly, your cells build more of them and retire damaged ones — a process called mitophagy. When you sit for hours, that cleanup stalls, and worn-out mitochondria generate excess free radicals that accelerate aging.
• Small actions compound because they affect multiple systems at once — Movement influences blood pressure, lipid metabolism, inflammation, and vascular function. When you walk briskly for five minutes, your muscles contract. Those contractions act like pumps, improving blood flow and oxygen delivery.
Over time, that repeated signal reshapes cardiovascular health. Those findings raised a key next question: if tiny increases in movement help, what happens when you stack small improvements across multiple habits at once?

Tiny Combined Upgrades Unlock Extra Years

For the eClinicalMedicine study, researchers set out to determine the minimum combined improvements in sleep, physical activity, and nutrition linked to longer lifespan and healthspan.4

Participants wore wrist accelerometers to measure sleep and moderate-to-vigorous physical activity, while diet quality was scored using a 0–100 Diet Quality Score based on intake of vegetables, fruits, grains, meats, fish, dairy, oils, and sugary drinks. Researchers essentially asked, “What’s the smallest realistic change that still adds measurable years?”

• Surprisingly small combined shifts were linked to one extra year of life — Compared to people at the lowest end of sleep, activity, and diet quality, an additional five minutes of sleep per day, 1.9 minutes of moderate-to-vigorous activity per day, and a five-point increase in diet quality score were associated with one additional year of lifespan.
• Four additional disease-free years required modest but coordinated effort — For healthspan, a combined improvement of 24 extra minutes of sleep, 3.7 minutes of moderate-to-vigorous activity, and a 23-point increase in diet quality score was associated with about four additional years free of major chronic disease. A 23-point diet score shift reflects changes such as adding one cup of vegetables daily.
• Higher combined scores linked to nearly a decade of added years — Participants in the most favorable groups — roughly 7.2 to eight hours of sleep, more than 42 minutes per day of moderate-to-vigorous activity, and higher diet quality — were associated with 9.35 additional years of lifespan and 9.45 additional years of healthspan compared to the least favorable groups. The pattern showed a near-linear trend: as combined behaviors improved, years gained increased.
The study reported a modest positive synergistic interaction for all-cause mortality, meaning the combined effect of sleep, activity, and diet was greater than the sum of each alone. Improving all three together multiplies the impact. When examined individually, much larger increases in a single behavior were required to achieve the same gain in lifespan.
• Physical activity drove the largest share of benefit — Moderate-to-vigorous physical activity appeared to be the primary contributor to lifespan and healthspan gains within the combined model. Benefits rose as sleep increased up to about 7.5 hours, then declined — meaning both too little and too much sleep were associated with worse outcomes. Diet alone showed a subtle association, but its role strengthened when combined with the other behaviors.
• Why combined changes outperform isolated ones — Shared physiological pathways, including energy regulation and metabolic adaptations, connect sleep, activity, and diet. Inadequate sleep disrupts appetite hormones and glucose control.
Low activity reduces metabolic efficiency. Poor diet worsens cardiometabolic strain — the combined burden on your heart, blood vessels, and blood sugar regulation. When you improve all three, you stabilize energy balance and reduce cumulative stress on your body.

How to Improve Sleep, Movement, and Diet with Small Daily Changes

The root cause driving shorter lifespan and shrinking healthspan isn’t a single disease. It’s the slow, daily erosion of metabolic function from too little movement, poor sleep, and low-quality food. You don’t need an extreme reset to see improvement. You need consistent, layered upgrades that raise your baseline health — think in terms of stacking small achievements that compound. Here’s how you take control.

1. Add five intentional minutes of brisk movement every day — If you’re mostly sedentary, start with five extra minutes of moderate movement, such as walking, daily. That means walking fast enough that talking feels slightly harder. Set a timer and treat it like a non-negotiable appointment. If you’re already active, add another five minutes to your current routine. Track your streak on a calendar and work your way up to a one-hour walk daily.
2. Cut 30 minutes of sitting by breaking it into micro-bursts — If you sit for work, stand up every hour and move for three minutes. March in place. Climb stairs. Walk the hallway. Six short breaks equal 18 minutes. Add a brief evening walk and you cross 30 minutes. Your muscles act like metabolic engines when they contract. Frequent activation resets your physiology throughout the day.
3. Prioritize high-quality sleep — If you’re not sleeping enough, extend your time in bed by five to 15 minutes this week. Darken your room. Remove screens at least 60 minutes before bed. Wake at the same time daily, even on the weekends. If you sleep more than nine hours and still feel exhausted, tighten your schedule and prioritize morning light exposure. Your brain and metabolism stabilize when sleep timing stabilizes.
4. Upgrade your diet with one measurable change at a time — Add half a serving of vegetables to one meal daily. Replace one processed snack with whole fruit. Swap vegetable oils for grass fed butter, ghee, or tallow. You’re not chasing perfection. You’re raising your daily average.
5. Layer the three habits together instead of overhauling one — If you try to double your exercise while ignoring sleep and food, you stall. Instead, combine small changes across all three areas. Add five minutes of sleep, two minutes of brisk movement, and one food upgrade in the same week.
That coordination drives the strongest gains in lifespan and years free of disease. You build momentum through repetition. If you’re overwhelmed, focus on one micro-target in each category this week. Your body responds to steady signals. Stack them daily, and the trajectory of your life shifts in your favor.

FAQs About the Impact of Small Lifestyle Changes

Q: Do small lifestyle changes really make a difference in lifespan?
A: Yes. Large population studies show that even very small improvements in daily habits are linked to longer life. Adding just five minutes of moderate-to-vigorous physical activity per day was associated with preventing up to 10% of deaths in most adults, showing that tiny increases in movement have measurable effects on survival.

Q: Why does combining sleep, diet and physical activity matter more than improving just one habit?
A: Sleep, movement, and nutrition influence many of the same biological systems, including energy balance, metabolism, and hormone regulation. When you improve all three together, the combined effect becomes stronger than focusing on only one area. This coordinated approach was associated with significant gains in both lifespan and years lived without chronic disease.

Q: How much change is needed to start seeing benefits?
A: The improvements linked to longer life were surprisingly small. Research found that adding about five minutes of sleep, roughly two minutes of moderate-to-vigorous physical activity, and a modest improvement in diet quality were associated with one additional year of lifespan.

Q: Who benefits the most from small improvements in physical activity?
A: The greatest gains were seen among people who were the least active to begin with. Individuals who rarely engage in brisk movement experienced the largest reductions in mortality risk when they increased activity by just a few minutes per day.

Q: What are the simplest steps to improve lifespan and healthspan?
A: Start with small daily adjustments that build over time. Add a few minutes of brisk walking, break up long periods of sitting, prioritize consistent high-quality sleep, and improve diet quality with simple food upgrades like adding vegetables or replacing processed snacks with whole foods. These small actions accumulate and create meaningful long-term health benefits.

About 40 million Americans live with varicose veins,1 yet most don’t think much about them until they start to hurt. These enlarged veins are often dismissed as a cosmetic problem — unwelcome in appearance but not taken seriously. That mindset keeps many people from paying attention early on, even when subtle symptoms start interfering with their daily life.

However, varicose veins are more than a surface issue. They reflect real changes in your circulation that, if overlooked, will lead to more persistent and serious health problems. Knowing what causes varicose veins and what they’re telling you about your overall vascular health allows for timely interventions and makes it easier to take care of your body long-term.

Understanding Varicose Veins — Causes, Risk Factors, and Diagnosis

Any vein close to the skin’s surface can become varicosed, meaning enlarged and twisted, but the veins in the legs are affected most often. These varicose veins tend to appear bluish or purple, raised above the skin, and may feel warm or tender to the touch. They often become more pronounced after long periods of standing or sitting.2

Although they may look similar to spider veins, varicose veins are deeper, larger, and more disruptive to healthy blood flow. Their presence reflects your body’s inability to move blood upward against the force of gravity.

• Healthy circulation depends on one-way valves in the veins — Beneath the surface, healthy veins rely on a network of one-way valves to return blood to the heart. These valves work in sync with muscle contractions in the lower body to keep blood moving upward, against gravity.3

With each step, your calf muscles compress nearby veins, helping blood overcome the long vertical distance back to the chest. This mechanism depends on vessel integrity and the coordination of many small components that maintain pressure and direction. When the system functions well, blood flows steadily and without interruption.4

• Varicose veins begin to form when these one-way valves no longer close completely — When the valves weaken or fail, blood slips backward and settles in the lower section of the vein. This accumulation increases local pressure, gradually distending the vessel and further impairing valve function.

Over time, the walls of the vein lose their elasticity and begin to bulge outward, creating a visible enlargement. Gravity amplifies this effect, especially in your legs, where the vertical distance from the heart is longest and the circulatory demand is greatest.5

• Several factors influence the likelihood of this process — Your risk of developing varicose veins increases with age, as the wear and tear on vein walls and valves builds gradually over time. If you’re a woman, hormonal shifts, especially during pregnancy or menopause, further relax the vein walls and make you more susceptible.

During pregnancy, circulating blood volume increases, hormone levels shift, and the expanding uterus compresses the pelvic veins, all of which elevate the pressure in leg veins. Genetics also play a strong role, along with obesity and sedentary behavior, which increase venous burden and reduce the efficiency of the muscle pump.

If your work keeps you on your feet for long stretches or seated for hours without movement, your veins face added stress. You’re also more vulnerable if you’ve had deep vein thrombosis (DVT), a leg injury, or a condition that affects connective tissue strength and flexibility.6,7,8

• How are varicose veins diagnosed? — A clinician will evaluate your legs while you’re standing, looking for visible swelling, bulging, or color changes. If venous reflux is suspected, a duplex ultrasound will be ordered to assess the direction and speed of blood flow, valve function, and signs of obstruction.

This test also helps differentiate between superficial veins and the deeper veins embedded within the muscles. Identifying where dysfunction originates allows for more precise treatment and helps rule out other vascular or lymphatic conditions.9,10

• Complications emerge as the condition advances — While many people live with varicose veins for years with minimal discomfort, it could turn into more serious problems if left unaddressed. One of its complications is superficial vein thrombosis, where a section of the vein becomes hardened, red, and painful due to clotting.

In some cases, these clots may extend into deeper veins, raising the risk of DVT, which carries the risk for a life-threatening embolism if a clot dislodges and travels to the lungs. As venous pressure continues to build, the skin around the ankles might become discolored, fragile, or inflamed, setting the stage for ulcers.

Chronic swelling, known as edema, places additional stress on the surrounding tissues, and fragile veins rupture with minimal trauma, causing spontaneous bleeding.11

Symptoms of Varicose Veins You Need to Watch Out For

The progression of varicose veins tends to be slow and subtle, so their early signs are often missed or dismissed, especially when the skin remains intact and the surrounding tissue appears normal. Paying attention to the following symptoms is key not just for relief but also to prevent more serious complications from taking hold:12,13,14

• A sense of heaviness often develops toward the end of the day — If you spend long hours standing or sitting, you’ll start to notice a dull ache in your legs that eases with rest but gradually returns more often. The area will feel tight or swollen, and walking upstairs or standing still for too long makes the discomfort more noticeable.

• Pain may shift from dull to throbbing or cramping — You’ll feel a throbbing sensation near the enlarged veins, sometimes accompanied by sharp or pulsing aches. The discomfort takes the form of a deep, cramping feeling that spreads through your calves or behind your knees.

You’ll also notice itching, tingling, or a burning sensation along the affected veins. These symptoms often intensify in the evening, making it harder to relax or get restful sleep.

• Swelling in the lower legs becomes more common and persistent — This is because your calves and ankles start to hold onto fluid that doesn’t go away quickly. By late afternoon, your shoes will feel tight, and your socks will leave deep marks around your ankles. In some areas, the skin over the swelling will look taut or slightly shiny, and you’ll begin to see subtle changes in color around the clusters of visible veins.

• Skin changes near affected veins signal advancing dysfunction — As your veins stay under pressure, the skin around them becomes increasingly vulnerable. Discoloration will begin to develop, often taking on a rusty or brown hue just above your ankle.

The skin in this area will feel thinner and more fragile. The texture will become dry or leathery, and you’ll notice more frequent itching. These changes show that the surrounding tissue is no longer getting enough oxygen or nutrients, an effect of impaired blood flow and poor venous return.

• Slow healing and venous ulcers may develop in later stages — If you leave the underlying dysfunction unaddressed, even small injuries in the affected area will take longer to heal. Minor scratches will linger and turn into shallow, stubborn wounds.

Over time, you’ll develop venous ulcers, often near the ankles, that resist healing and become prone to infection. These ulcers will continue to return unless the pressure in your veins is reduced, and they will require ongoing care to prevent further skin breakdown and tissue damage.

• Persistent symptoms signal the onset of chronic venous insufficiency — Chronic venous insufficiency is the term used when your symptoms become persistent and continue to worsen. At this stage, your veins will no longer be able to maintain healthy circulation. The discomfort will spread beyond individual veins and affect your entire lower leg, leading to fatigue, limited mobility, and difficulty staying on your feet for extended periods.

If these symptoms begin to appear, don’t ignore them or assume they’ll resolve on their own. The longer the underlying pressure builds, the harder it becomes to reverse the damage.

Strategies to Address Varicose Veins

Managing varicose veins requires more than cosmetic correction — it involves addressing the underlying pressure, restoring circulation, and protecting surrounding tissue from long-term damage. The following strategies are commonly used in conventional care for varicose veins:

• Compression therapy is the standard first-line approach — Medical-grade compression stockings apply graduated pressure to the lower legs, which helps support the vein walls and encourages blood to flow upward toward the heart.

This approach does not reverse the condition, but it often reduces discomfort and swelling. When compression isn’t enough, medical providers recommend procedures that close or remove dysfunctional veins to reroute blood through healthier ones.

• Minimally invasive procedures are used to collapse or remove damaged veins — The most commonly used techniques include sclerotherapy, where a chemical agent is injected to scar the vein shut, and endovenous thermal ablation, which uses heat from lasers or radiofrequency to collapse the affected vessel.

In some cases, mechanochemical ablation combines mechanical disruption with a sclerosing agent to enhance effectiveness. For larger or more stubborn veins, surgical options such as ambulatory phlebectomy or vein ligation may be used to physically extract or tie off the damaged vein.

For those seeking alternatives beyond mechanical or surgical correction, several noninvasive therapies are available to help you support your vascular tone more holistically:

• Dimethyl sulfoxide (DMSO) offers a broad-spectrum alternative for vascular support — DMSO is a naturally occurring substance with potent anti-inflammatory, analgesic, and circulation-enhancing effects. When applied topically, it penetrates deep into the tissues. In people with varicose veins, this often translates into reduced visibility of enlarged veins, diminished pain or itching, and lessened pressure in the lower legs.15,16

• DMSO plays a significant role in healing venous ulcers and skin damage caused by poor circulation — In clinical studies and long-term case reports, it has shown an ability to promote rapid tissue repair, support granulation, reduce swelling, and prevent infection.17,18

Among diabetic patients with chronic foot ulcers, daily DMSO application helped restore tissue integrity in cases that had resisted conventional care.19 Its effectiveness appears to extend not only to wound healing but also to reducing the hyperpigmentation, thickening, and fragility often seen in longstanding venous insufficiency.20,21

• Users report improvements in vein tone, skin integrity, and local circulation — As a venotropic compound, DMSO improves the tone and responsiveness of veins, helping to normalize blood return over time. It also appears to reduce capillary bleeding and post-inflammatory discoloration.22 Take a deeper look at how DMSO supports skin repair and vascular health in “How DMSO Revolutionizes Skin Care and Dermatology.”

• Inclined bed therapy uses body positioning to enhance venous return — It offers a structural, systemic method for improving venous return without any invasive measures. By raising the head of the bed by 6 inches (5 degrees), your body lies at a gentle angle that uses gravity to assist the movement of blood and lymph as you sleep.

This method originated from the observation that plants circulate fluids using density and gravitational gradients, and that similar forces may support human circulation as well. In one experiment, varicose veins disappeared after four weeks of sleeping on a 6-inch incline, which is a sign that “a positive change in circulation” had been achieved.23

To explore this method in greater depth, watch the video below and read “The Surprising Benefits of Inclined Bed Therapy” for a full breakdown of how it works to support circulation.

How to Lower Your Risk of Varicose Veins

You can’t change your genetics or the natural aging process, but you do have control over how much daily stress your veins are forced to handle. Supporting healthy blood flow is one of the most effective ways to prevent varicose veins from developing or worsening. That means finding ways to reduce the pressure in your lower legs throughout the day. I recommend adopting these strategies:24

1. Move regularly — If you sit or stand for long stretches at work, make a point to change positions often. Flex your ankles, shift your weight from leg to leg, or take brief walks to keep the blood in your calves moving upward. When you’re seated, avoid crossing your legs or holding your knees tightly together for long periods, since this limits circulation and increases pressure in your lower limbs.

2. Raise your legs during the day — This helps relieve venous pressure by letting gravity assist circulation rather than working against it. Whenever possible, rest with your legs elevated above the level of your heart. This gives your veins a break and helps reduce swelling, especially after activity. Using pillows or a wedge cushion while lying down or reclining can make this a regular part of your daily routine.

3. Choose your shoes wisely — High heels reduce the ability of your calf muscles to contract fully, weakening the natural pumping action that moves blood upward. Choose shoes with lower heels and enough support to let your calves engage properly. Tight clothing around the waist, thighs, or calves also interferes with venous return, especially if worn for long hours.

4. Manage your weight — This reduces unnecessary strain on your lower body. Even a modest loss of excess weight will ease the burden on your venous system and improve overall circulation. Daily walking, swimming, or cycling keeps the blood moving and strengthens the muscle groups that support vein function. You don’t need intense workouts — what matters is consistency and rhythm, especially in the legs.

Frequently Asked Questions (FAQs) About Varicose Veins

Q: What are varicose veins and why do they develop?

A: Varicose veins are enlarged, twisted veins that usually appear in the legs. They form when the one-way valves in your veins begin to fail, allowing blood to flow backward and pool. This buildup increases pressure, stretches the vein walls, and causes the veins to bulge outward. Over time, this signals an underlying problem with circulation, not just a surface issue.

Q: What do varicose veins look and feel like?

A: You’ll usually notice them as bulging, bluish or purple veins raised above the skin’s surface. They may feel warm or tender to the touch, and symptoms like aching, swelling, or heaviness often intensify after standing or sitting for long periods. As the condition progresses, you may also experience throbbing, itching, or skin discoloration.

Q: Are varicose veins dangerous?

A: Yes, especially if left untreated. Over time, they lead to superficial vein thrombosis, deep vein thrombosis, venous ulcers, skin breakdown, and chronic swelling. These complications may begin subtly but grow more serious without early intervention.

Q: How does DMSO help with varicose veins?

A: DMSO (dimethyl sulfoxide) helps ease inflammation, improve circulation, and promote healing in damaged tissue. It’s especially helpful for reducing pain, shrinking visible veins, and speeding recovery from ulcers or skin changes caused by poor circulation.

Q: How do I use inclined bed therapy for varicose veins?

A: Raise the head of your bed by 6 inches to create a gentle downward slope from head to toe. This sleeping position improves fluid drainage, reduces nighttime swelling, and supports better circulation in the legs.

It might feel counterintuitive at first, since you’d expect elevating your feet to be the goal, but tilting the entire body allows gravity to assist blood and lymphatic flow more continuously. Many people report visible improvements within weeks of consistent use.

In 2010, I published an article on this site discussing vitamin K prophylaxis for newborns. That article reflected the state of a legitimate scientific debate that was active at the time, centered on a 1992 study by Golding et al. published in the BMJ that had reported a possible link between intramuscular vitamin K and childhood leukemia.1

Sixteen years later, I owe you an update, because the science has moved decisively and my position has changed with it. That is how evidence-based medicine is supposed to work. When the data changes, informed positions change too. Every reference in this article has been retrieved from PubMed and can be independently verified by PMID number.

Why Newborns Are Vulnerable

Newborns arrive with very limited vitamin K reserves. The vitamin does not cross the placenta efficiently, breast milk contains only trace amounts of it, and the newborn gut lacks the bacterial population that eventually helps produce it.2,3

This creates a window of vulnerability during the first six months of life when an infant’s ability to form blood clots is compromised.

Vitamin K deficiency bleeding, or VKDB, is classified into three forms based on timing: early VKDB occurs within 24 hours of birth and is typically associated with maternal medications; classic VKDB occurs between days one through seven and is related to delayed feeding; and late VKDB occurs between two weeks and six months of age — the most dangerous form because it frequently presents as bleeding inside the brain.4,5

Without any form of prophylaxis, late VKDB occurs in roughly 5 to 80 per 100,000 live births, depending on the population.6 When it presents as intracranial hemorrhage, the mortality rate ranges from 20% to 50%, and survivors frequently suffer permanent neurological damage.7

How Effective Is the Vitamin K Shot?

The most comprehensive systematic review on this topic was published by Sankar et al. in the Journal of Perinatology in 2016. Pooling surveillance data from four countries, they found that a single intramuscular or subcutaneous dose of vitamin K at birth reduced the risk of late VKDB by approximately 98% — a pooled relative risk of 0.02 (95% CI, 0.00-0.10).8

The American Academy of Pediatrics reaffirmed its recommendation for universal intramuscular vitamin K at birth in a 2022 clinical report published in Pediatrics.9 That recommendation has been consistent since 1961 — over six decades of clinical experience.

A 2026 review by Mirone et al. in the International Journal of Molecular Sciences provided a detailed molecular analysis of how vitamin K prophylaxis works and confirmed that the intramuscular route provides near-complete protection against both classic and late VKDB.10

What About Oral Vitamin K?

Some parents prefer oral vitamin K because it avoids an injection. Several European countries, including Switzerland and the Netherlands, have used multi-dose oral protocols with partial success.

However, the evidence consistently shows that oral prophylaxis is inferior to injection for preventing late VKDB. Sankar et al. found that a single oral dose dramatically increased the risk of late VKDB compared to injection (RR 24.5). Multiple oral doses performed better but still showed a nonsignificant trend toward higher risk (RR 3.64).11

A Dutch study by Löwensteyn et al. (2019) demonstrated that even increasing the oral vitamin K dose sixfold produced only a modest reduction in intracranial VKDB. The authors concluded that undetected cholestasis — a liver condition common in breastfed infants — prevents effective absorption of oral vitamin K, no matter how high the dose.12

A 2026 Swiss surveillance study confirmed this pattern. Over six years of monitoring 505,708 births, every VKDB case involved either parental vitamin K refusal, unrecognized cholestasis, or both.13

A 2025 review in Nutrition Reviews added prospective evidence that exclusively breastfed infants can develop vitamin K insufficiency even after receiving the shot at birth, supporting the case for continued supplementation during the first three months.14

The Cancer Concern Has Been Put to Rest

The most persistent fear about vitamin K stems from Golding et al.’s 1992 case-control study, which reported a nearly twofold increased risk of childhood cancer after intramuscular vitamin K (OR 1.97; 95% CI, 1.3-3.0).15 This finding triggered a wave of research. Four major population-based studies investigated the question, and the results were unanimous — no association:

• Ekelund et al. (1993) — 1.38 million infants in Sweden. Cancer OR: 1.01. Leukemia OR: 0.90. No association.16
• Klebanoff et al. (1993) — 54,795 children, published in the New England Journal of Medicine. Cancer OR: 0.84. Leukemia OR: 0.47.17
• von Kries et al. (1996) — Population-based study in Germany. Leukemia OR: 0.98. No association.18
• Fear et al. (2003) — UK Childhood Cancer Study, 2,530 cancer cases, 4,487 controls. No association with any childhood cancer.19

Brousson and Klein reviewed this evidence in 1996 in the Canadian Medical Association Journal and concluded there was no compelling reason to change the standard practice.20 The 2026 Mirone et al. review confirmed this conclusion with three additional decades of data.21 The cancer question is settled. It should no longer be a factor in any parent’s decision about vitamin K.

The Troubling Rise in Refusal

Despite the clarity of the evidence, vitamin K refusal is increasing. A 2026 JAMA study by Scott et al. documented that the proportion of U.S. newborns not receiving vitamin K rose from 2.92% in 2017 to 5.18% in 2024 across more than five million births.22

An international survey published in Pediatric Blood & Cancer found that parental refusal of intramuscular injection is the most common barrier to prophylaxis in high-income countries.23

What happens when parents refuse? A 2026 case report in Child’s Nervous System described a two-month-old who arrived at the emergency room unresponsive with a blown pupil. CT scan revealed a massive brain hemorrhage. His INR — the measure of blood clotting — was greater than 15 (normal is around 1). He had not received vitamin K at birth. He required emergency surgery to remove part of his skull to relieve brain pressure.24 He survived. Many do not.

Shah, Brumberg and La Gamma published a review in 2020 examining the parallels between vitamin K refusal and vaccine hesitancy, noting that both are driven by misinformation on social media and geographic clustering.25

Where I Stand Now

Based on the totality of the published evidence, I support vitamin K prophylaxis for all newborns. The intramuscular route provides the most reliable protection. The cancer concern has been definitively resolved.

I advise every parent to discuss vitamin K with their child’s pediatrician. If you are uncertain, the prudent choice is to give the shot. The risks of VKDB — brain hemorrhage, permanent damage, death — are real and well documented. The risks of the injection are negligible.

My understanding of this topic has evolved as the evidence has grown. That is how science is supposed to work. When the data changes, informed positions change with it. The data is clear: vitamin K saves lives.

A Note to Parents

If you are a parent researching this topic, I want to be direct with you. The internet contains a significant amount of misinformation about vitamin K. Some of it may reference my own 2010 article. That article reflected the state of a scientific debate that has since been resolved. The science moved forward, and so have I.

Your pediatrician is your best resource for newborn care decisions. Vitamin K deficiency bleeding is rare, but when it occurs, the consequences can be devastating and irreversible. A single injection at birth can prevent it. Please talk to your doctor.

Getting older is part of life. You expect to slow down, feel a little more tired, and notice more wear and tear. But many of the symptoms people associate with “normal aging” — like creeping fatigue, brain fog, or chronic aches — could actually be signs that your body is aging too fast because it’s constantly under attack from poor diet, inappropriate lifestyle, and toxins in the environment.

In the featured video, I spoke with Dr. Shawn Baker on his podcast to explain why disease is not separate from aging — rather, it’s aging accelerated. Disease is like putting the pedal to the metal on the destruction of your biology. If you want to slow the clock, you have to stop the biological damage and give your cells what they need to heal.

Disease Is Typically an Accelerated Form of Aging

If you want to live long and live well, it’s important to understand the distinction between normal aging and disease. Normal aging is a gradual process marked by a slow decline in cellular repair and regeneration. Disease, on the other hand, is what happens when those natural mechanisms are overwhelmed or sabotaged by constant biological stress, causing what should be a gradual decline to accelerate.

• The Free Radical Theory of Aging — Proposed by Denham Harman in the 1950s, this theory suggests that unstable molecules called free radicals drive cellular dysfunction.1 It’s the resulting oxidative stress that breaks down critical cellular components, like your DNA, cell membranes, mitochondria, and proteins. Over time, this damage accumulates and accelerates the aging process from the inside out.

• Your body is built to repair itself — Your body relies on endogenous antioxidant systems like glutathione and superoxide dismutase to neutralize oxidative stress and maintain cellular integrity. Cellular energy is what you need to support these protective systems. Understanding how your body creates and maintains that energy is essential if you want to slow aging and prevent disease.

• Cellular energy fights premature aging — In our discussion, I shared insights from my book, “Your Guide to Cellular Health,” where I emphasize that energy is the foundational currency of healing. Without sufficient cellular energy, even the best nutrients and therapies won’t work as intended. Aging may be inevitable, but disease is avoidable if you understand which inputs restore energy and which ones destroy it.

Why Your Food Choices Could Be Aging You Faster

Food is the most consistent and direct input you give your body. Unfortunately, the modern diet is designed to sabotage your health.

• Linoleic acid (LA) is the worst offender in your diet — LA is an omega-6 polyunsaturated fat found in soybean, canola, corn, safflower, and sunflower oils. It’s in almost every processed food. I call these fats PUFs, short for polyunsaturated fats. That term is more accurate than PUFAs (polyunsaturated fatty acids) because most people recognize them as fats, not acids.

These highly refined vegetable oils have become the primary source of calories for most people, and this shift has profoundly reshaped the human diet — not for the better. When LA intake exceeds 2% of your daily calories, oxidative stress rises dramatically, leading to widespread damage to all your important cellular tissues.

• LA embeds in your cells and drives oxidation — Once incorporated into cell membranes, LA is highly susceptible to oxidative damage.

This peroxidation process generates toxic byproducts like oxidized linoleic acid metabolites (OXLAMs), 4-hydroxynonenal (4-HNE), malondialdehyde (MDA), and epoxyketooctadecenoic acids (EKODEs), which disrupt mitochondrial membranes and signaling. These compounds accelerate aging and lay the groundwork for chronic disease.2,3

• LA destroys cardiolipin and mitochondrial integrity — We also discussed cardiolipin, a vital fat in your inner mitochondrial membrane that stabilizes energy production.4 It also plays an essential role in forming mitochondrial super complexes by crowding Complexes I through V closer together, which facilitates efficient electron flow through the electron transport chain (ETC).

Structurally, cardiolipin has four fatty acid tails. However, with the modern diet, most of those tails are now made of LA. This destabilizes the structure. It’s like you burn it up — it self-destructs the mitochondria, which are essential for producing cellular energy. As a result, large portions of your mitochondria die prematurely because the cardiolipin is loaded with LA.

• Carbs have been wrongfully vilified — In the interview, I described carbohydrates as “the innocent victim at a fire” because they’re often blamed for metabolic problems. Markers like insulin resistance, elevated glycohemoglobins, advanced glycation end products (AGEs), and glycosylated proteins do rise with elevated glucose. But these are symptoms, not root causes.

In fact, paradoxically, lower glucose levels in a broken system can sometimes accelerate damage by further disrupting redox signaling. The real issue isn’t carbohydrates themselves, but the refined versions often paired with damaging vegetable oils and high-fructose corn syrup (HFCS). Think donuts and fries — these foods contain the trifecta of aging accelerators.

To understand the role of healthy carbohydrates in gut and metabolic function, check out “Why Your Gut Needs Carbs for Optimal Health.”

• Fructose by itself is not pernicious — I also clarified that fructose isn’t inherently harmful. There’s nothing dangerous about eating a small apple or any whole fruit when your gut and metabolism are functioning well. Fruit, I believe, is one of the healthiest foods on the planet. The difference is that the fructose in fruit is delivered in its natural matrix, along with fiber, water, and polyphenols that slow absorption and support the microbiome.

• HFCS and fruit juice are a different story — When fructose is extracted from its whole food matrix, as in HFCS or fruit juice, it becomes disruptive to metabolic health. HFCS accelerates many of the same pathologies triggered by omega-6 fats, including fatty liver disease.

Both elevated fructose and PUFs promote similar patterns of metabolic breakdown. While fruit juice isn’t identical to HFCS, the fructose it contains has still been stripped from its original matrix. This leads to sharper spikes in blood sugar and pathological insulin responses that wouldn’t occur with whole fruit.

• Even fruit becomes problematic when the gut is broken — People with a disrupted microbiome may not be able to tolerate even healthy foods like whole fruit. This happens when vegetable oils and other toxins cause a massive gut imbalance, creating a microenvironment with elevated oxygen levels that kills off the beneficial anaerobic bacteria, which produce a very important fat called butyrate.

• Butyrate is a short-chain fat that fuels colonocytes — When butyrate production drops, colonocytes begin to die, which leads to the breakdown of the gut barrier and the development of leaky gut.

This creates a vicious cycle where, instead of being metabolized by beneficial bacteria, healthy fibers like fruit or grains are processed by the wrong microbes. The result is an increase in endotoxin production, another mitochondrial poison that worsens metabolic destruction.

• Removing dietary toxins restores your ability to thrive — Healing starts when you eliminate vegetable oils, processed sugars, and refined carbs from your diet. Once the inflammatory load is lifted, your beneficial gut bacteria will repopulate and butyrate production increases. Fruit and fiber become nourishing again instead of triggering reactions.

• Delivering butyrate where it matters has long been a challenge — When taken orally, butyrate is typically absorbed too early in the digestive tract; when administered rectally, it only reaches a limited portion of the colon. That’s why a time-release formulation is needed — one that distributes butyrate gradually along the length of the large intestine.

This approach ensures that the areas most affected by inflammation and microbial imbalance receive adequate support, allowing for a more complete restoration of gut health. This is a solution we’re currently developing, and I’ll be sharing more details as it becomes available.

C15:0 Is the Most Important Fat You’re Likely Not Getting

One of the most important topics we covered in our discussion was the role of specific fats in mitochondrial health — particularly C15:0 (also known as pentadecanoic acid). This little-known, odd-chain saturated fat has been recognized as essential for your health. In fact, it’s likely more important than omega-3 fats to your biology.

• C15:0 protects cardiolipin from damage — Unlike LA, which oxidizes easily and drives inflammation, C15:0 is highly stable and resistant to oxidation.5 Substituting C15:0 into cardiolipin makes the structure more stable and efficient. This small structural change boosts energy output and cellular lifespan. As I noted in the interview, C15:0 could increase longevity anywhere from 10% to 80%.

• C15:0 is also a signaling fat with systemic benefits — It modulates inflammation, improves insulin sensitivity, and supports brain metabolism. Unlike most dietary fats, which only serve as fuel or storage, C15:0 acts like a hormone, influencing genetic expression and intercellular communication. These signaling roles help regulate immune response and metabolic rate.6

• Most people are deficient in C15:0 due to modern farming practices — Your body can’t produce meaningful amounts of C15:0 on its own; it needs to come from your diet. But grain-fed livestock does not generate this fat, which makes it nearly absent from the modern food supply. To get enough C15:0, you’d need to drink about half a gallon of milk or eat several pounds of cheese — and that’s if the animals were grass fed.

Grain-fed dairy contains little to none, because C15:0 is found only in grass, not in grains. For most people, food alone is no longer a reliable source. This is why we’re developing a C15:0 supplement that would help you optimize your intake of this fat affordably — and I’ll be sharing more about that in the near future.

Learn more about how C15:0 supports cellular health, longevity, and metabolic function in “C15:0 — Found in Dairy — May Be an Essential Fat.”

Environmental Toxins That Accelerate Aging

In addition to dietary toxins, your body is also being hijacked by invisible environmental poisons that silently accelerate cellular breakdown. Two of the biggest offenders are electromagnetic fields (EMFs) and estrogenic pollutants, which are nearly impossible to avoid in modern life. These toxins share one destructive mechanism — they flood your cells with calcium and trigger the formation of peroxynitrite, a powerful free radical.

• EMFs are a biologically disruptive form of wireless pollution — EMFs open voltage-gated calcium channels in the cell membrane, allowing excessive calcium to pour into the cytoplasm. This calcium surge triggers nitric oxide to combine with superoxide, producing peroxynitrite. Peroxynitrite damages proteins, lipids, and DNA, and it wreaks havoc on mitochondrial membranes.

• Telecom industries suppress EMF health risks — Just like Big Tobacco once denied the cancer risks of smoking, telecommunication companies have dismissed the dangers of EMFs. Studies that show harm are ignored or buried, while industry-funded research shows inconclusive results. This creates confusion and gives the illusion of safety. However, biological damage occurs long before symptoms appear.

• Microplastics are another widespread mitochondrial toxin — These particles have been detected in the blood, brain, liver, testes, and placenta. Microplastics carry endocrine-disrupting chemicals (EDCs) that mimic estrogen and interfere with hormone signaling, contributing to estrogen dominance and hormonal imbalance, a defining feature of modern premature aging.7

EDCs and EMFs, along with excess linoleic acid and endotoxins, are what I call the “Four E’s.” To address these four primary drivers of inflammation, I invite you to explore my article, “Cellular Health Revolution — Unveiling Hidden Threats and Empowering Solutions.”

Tracking Metabolic Function with HOMA-IR

One of the most effective ways to prevent disease and slow premature aging is by tracking how your body is functioning before symptoms appear. Biomarkers related to mitochondrial health, blood sugar regulation, and metabolic resilience provide early warnings when something’s off. In the interview, I highlighted one of the most practical tools for this — the HOMA-IR score.

• What HOMA-IR tells you — HOMA-IR, which stands for Homeostatic Model Assessment of Insulin Resistance, is a simple but powerful way to gauge how efficiently your body is responding to insulin. A high HOMA-IR score suggests your body is beginning to resist insulin’s signals — a key driver of aging, inflammation, and metabolic disease.8

• How it works — You only need two standard fasting lab values to calculate your score — fasting glucose and fasting insulin, both taken first thing in the morning. With those two numbers, you plug them into this formula:

HOMA-IR = (Fasting Glucose in mg/dL × Fasting Insulin in μU/mL) ÷ 405

• Interpreting your results — A score below 1.0 generally indicates healthy insulin sensitivity. A score above 1.0 suggests you may be moving toward insulin resistance, even if your glucose still looks “normal” on a basic lab report. The earlier you identify that shift, the more effectively you can intervene through diet and lifestyle changes.

• Why HOMA-IR beats complex testing — The euglycemic hyperinsulinemic clamp is the gold standard for measuring insulin sensitivity in research, but it’s completely impractical for daily life. It requires IV infusions over several hours in a clinical setting. HOMA-IR, while not perfect, offers enough accuracy for personal health tracking without the complexity or cost.

• Making it more accessible — To make this type of testing more accessible, we’re working on an at-home testing system that uses a simple finger prick to collect blood, which is then mailed in for analysis. The results would be comparable in quality to what you’d receive from major labs at a fraction of the cost. This approach aims to remove barriers to testing, bypass insurance restrictions, and give you direct access to your metabolic data.

Reclaiming Biological Foundations — Movement, Sunlight, and Joy

While supplements and advanced therapies have their place, they aren’t a substitute for the biological foundations your body depends on. Your body was built to move, to be outdoors, to experience light, and to generate meaning through Joy. These factors are essential for energy, longevity, and emotional balance. When you neglect them, every system begins to deteriorate.

• Movement is a biological requirement — You can’t be truly healthy without regular physical activity. Walking remains one of the most effective and accessible forms of movement. It requires no equipment and fits into nearly any lifestyle; almost everyone can do it.

Walking supports mobility, flexibility, and immune function — and when it’s missing, health declines across the board. Your health begins to suffer when you lose the ability to walk, because everything is connected to movement. While walking is the simplest and most accessible form, any kind of movement — whether it’s dance, yoga, or stretching — will also help.

• Sunlight is essential, but keep this caveat in mind — Sun exposure regulates circadian rhythm, stimulates vitamin D production, supports immune balance, and promotes mitochondrial melatonin production.9

More than that, the sun may directly fuel mitochondrial energy via a process I call photometabolism, wherein you turn energy from the sun and integrate it into your biology. In this way, sunlight could act as a complementary energy source, much like nutrient-dense fuel.

However, this process only works safely when your tissues are free of unstable fats. If your body is saturated with LA, sun exposure will do more harm than good by increasing your risk of oxidative damage and sunburn. That’s why it’s important to avoid high-intensity sun exposure until you’ve been off vegetable oils for about six months. Discover the keys to safer sun exposure in “The Role of Sun Exposure in Optimizing Your Cellular Health.”

• Joy is the natural result of optimal biology — Baker asked why I included “Joy” in the title of my book on cellular health, and it’s because Joy is not just a mindset — it’s a biological outcome. Joy is not fleeting like happiness, but a deep, sustained sense of coherence and purpose.

The brain consumes 20% of the body’s energy, so when mitochondrial output drops, emotional resilience collapses. You can’t create Joy in a body starved for energy. When your cells have the energy they need and your systems are functioning properly, Joy becomes your default state — not something rare or fleeting.

Systemic Failure of Conventional Medicine

Toward the end of our conversation, Baker and I talked about what has gone wrong in conventional medicine and why so many people remain sick, misdiagnosed, or stuck on a fast track to accelerated aging.

• Drug-based care replaced root cause medicine — Modern medicine follows the Rockefeller model, where symptoms are matched to drugs rather than investigated for underlying causes. This framework prioritizes drug sales over patient outcomes and locks physicians into algorithmic, surface-level care that overlooks true healing.

• Scientific journals have been hijacked by industry influence — We also discussed how conflicts of interest have distorted medical research, including disclosures from former editors of top journals like The New England Journal of Medicine.

The implementation of this industry-driven distortion has become pervasive and represents one of the most dangerous philosophies adopted throughout the medical field, as it shapes how research is interpreted, published, and ultimately applied in clinical practice.

• Physicians are trapped in a broken framework — Most doctors want to help, but the structure of insurance-based medicine prevents them from doing meaningful work. In many cases, physicians have only five to 15 minutes with each patient — nowhere near enough time to fully assess what’s going on or to address the root cause of disease. For doctors who want to practice real, foundational medicine, stepping outside the system is often the only way to do it.

Frequently Asked Questions (FAQs) About Accelerated Aging and Disease

Q: How is disease connected to aging?

A: Disease is not separate from aging — it’s aging that’s been accelerated by chronic biological stress. When your mitochondria are impaired and your body is overwhelmed by toxins, inflammation, or poor metabolic signaling, repair systems begin to fail. What we often call “normal aging” is frequently the result of avoidable damage that pushes your biology beyond its natural pace.

Q: Why is linoleic acid considered more harmful than other dietary ingredients?

A: Linoleic acid, found in most vegetable oils, embeds into your mitochondrial membranes, where it oxidizes and generates toxic byproducts like 4-HNE and OXLAMs. These compounds disrupt energy production and promote chronic inflammation. While sugar and high-fructose corn syrup are harmful in excess, LA lingers in your tissues and drives damage long after it’s consumed.

Q: Is fructose always harmful, or does the source matter?

A: Fructose is only problematic when it’s removed from its whole-food context. In fruit, it’s packaged with fiber, polyphenols, and water that slow its absorption and support your microbiome. But when extracted, as in fruit juice or high-fructose corn syrup, it overwhelms the liver, spikes insulin, and mimics the damaging effects of vegetable oils. If your gut is healthy, whole fruit is one of the most beneficial foods you can eat.

Q: What is C15:0, and how does it support healthy aging?

A: C15:0 is a rare, odd-chain saturated fat found in grass fed dairy. It resists oxidation and helps stabilize cardiolipin, a key fat in the mitochondrial membrane that supports energy production. Unlike polyunsaturated fats like linoleic acid, C15:0 protects mitochondrial function rather than disrupting it. Due to modern farming practices, however, most diets today are deficient in this essential fat.

Q: What does Joy have to do with energy and aging?

A: Joy is not just an emotion — it’s a sign that your biology is working properly. Your brain consumes about 20% of your body’s energy, and when mitochondrial output declines, so does your capacity for mental clarity, emotional balance, and motivation. When energy systems are restored, Joy becomes your natural state — not something that is fleeting or constantly out of reach.

In my interview with Dr. Patrick Gentempo, a longtime friend and respected chiropractor, we discussed the importance of knowing your own health philosophy. We explored topics such as self-trust, fear, and the role of curiosity in guiding you toward good decisions. Our conversation highlighted how easy it is to get swept up in a system that emphasizes quick fixes instead of true healing.

You might think a prescribed drug or an invasive procedure is the only answer because that is the message coming from some powerful voices. Yet, genuine “health care” is not just a set of steps or pills. It involves your choices, your beliefs, and your willingness to understand what your body truly needs. Gentempo described his early days in chiropractic care, where he frequently encountered patients who assumed that a doctor always knew best.

Those same individuals often had no real sense of their own ability to heal. In many cases, they simply replaced their inner wisdom with a blind trust in practitioners wearing white coats. Gentempo’s point is one I have voiced time and again — each of you should take a more active role in your own health. Part of that means understanding that most so-called “health care” is actually designed to handle crises and emergencies, rather than promote day-to-day well-being.

There is certainly a place for emergency interventions. If you experience a broken bone or life-threatening infection, going to a hospital is clearly the right move. But as you will see, making wise decisions in everyday life often prevents these problems or at least lessens their severity.

Throughout my professional journey, I have found that the best outcomes happen when you trust your own judgment enough to consider alternative approaches. Gentempo agrees. He shared a story of being nearly pushed into knee surgery, only to pause and remember his core belief that the body is self-healing and self-regulating. This pause gave him room to explore a natural path — one that ultimately led to a full recovery without surgery.

Embracing Self-Trust and Personal Choice

During our conversation, we also focused on how fear disrupts your ability to trust yourself. I have often seen people become so caught up in what they are told by experts that they lose sight of their own experiences and gut feelings. Gentempo explained that, without a personal philosophy, you naturally adopt someone else’s. That point deserves your attention. It means your choices come not from a place of conviction but from pressure or habit.

When you decide to live by your own philosophy, you begin to ask questions. You might wonder: Does a proposed treatment align with how you view health, or does it only address a symptom? Have you looked for credible data and then checked how it resonates with your experiences?

This shift might involve saying “no” to a recommendation or stepping away from a risky drug. It often feels unusual, especially if you are used to following directions without challenging them. Yet, in the long run, this approach could save you from unneeded therapies and help you find better solutions.

During our discussion, Gentempo recalled times in his practice when he saw the direct power of self-healing. He watched patients who tried conservative, noninvasive options before resorting to surgery. Many of them improved. This reminded me of a key study in the New England Journal of Medicine showing that certain knee surgeries were no better than sham procedures.1

It underscores how assumptions about standard care don’t always hold up. You deserve to know such information to avoid getting swept into fear-based decisions. The moment you break free from that cycle of dread, you become much better equipped to evaluate the merits of any treatment. You move from being told what to do to deciding what to do. That is the essence of real self-trust.

Questioning the ‘Health Care’ Label

A large part of my conversation with Gentempo centered on the way our society approaches health. We both find it troubling that so much money and energy goes into a system better described as “sick care.” Despite massive health care spending, many people remain unwell or become sicker as they age.

You look around and see countless advertisements for drugs, along with stories from neighbors and friends who juggle multiple prescriptions. That seems perfectly normal in our current age, but it does not reflect what true health looks like. In a genuine health care system, the priority would be to help you stay healthy in the first place. Rather than constantly placing you in a reactive stance, it would center on prevention and healthy lifestyle habits.

Gentempo pointed out that medication-based care does not automatically become “bad.” If you encounter an acute crisis, pharmaceutical or surgical interventions are often lifesaving. The issue arises when prescriptions and procedures are used for mild or chronic conditions without considering simpler, safer solutions. This over-reliance on medicine leads to a cycle where people keep adding more drugs to handle side effects, and no one ever addresses the root cause.

I have spent many years showing readers how to handle common health concerns through smart, natural methods. Whether it is taking steps to optimize your vitamin D levels or learning how to manage stress before it spirals, you have options beyond the standard sick-care path. I urge you to remain curious and look for ways to maintain vitality. Do not wait for permission to try something as basic as healthy eating, proper sleep, or a thoughtful supplement routine.

Crafting a Health Philosophy That Fits You

As Gentempo explains, forming a personal health philosophy means taking the time to decide what you believe about the nature of your body and how it heals. Some of you likely feel quite certain that the human body, given proper support, is incredibly resilient. You believe your energy and overall function improves with simple steps like removing toxins, eating real foods, and staying active.

Others still cling to the assumption that a doctor’s prescription or a scalpel is always required to correct any health issue. Gentempo and I suggest you consider how your current beliefs were formed. Did you develop them through your own experience and valid research, or have you absorbed them from the environment around you? If you learn to “audit” your beliefs, you keep the good ones and discard those that do not serve you anymore.

In our interview, we also discussed how people feel lost when they have no guiding philosophy at all. That leaves you vulnerable to picking up any passing idea or commercial message that seems official.

When you have a clear sense of what health means to you — when you know how you think your body should be cared for — other people’s claims become easier to evaluate. You may say, “That lines up with my philosophy,” or “This goes against how I understand health,” and proceed from there.

Deciding on your own philosophy does not mean you go it alone and never accept outside help. Rather, you become the ultimate judge. You gather insights from various sources, verify the evidence, then see if it resonates with your view of reality. If it does, you might adopt it. If not, you discard it without feeling guilty. A personal philosophy is not a set of unchanging rules; it shifts as new knowledge emerges.

Old Assumptions and New Insights

We talked about how easy it is to repeat old assumptions without checking if they are still correct. Maybe you have believed something like “saturated fats are harmful” or “any government-approved drug must be 100% safe.” As Gentempo and I noted, you then look back and find that many modern ideas turned out to be mistaken. Studies challenging long-held beliefs pop up regularly, yet people keep following the same paths out of habit or fear.

An example is the use of seed oils, which contain linoleic acid. You’ve likely seen repeated claims that these are “heart-healthy” alternatives, when in reality they’re mitochondrial poisons. You might have grown up with the notion that vegetable oils in processed foods were better for you, only to learn now that butter, ghee, and coconut oil are healthier options.

In my conversation with Gentempo, I pointed out that changing your perspective does not make you weak or indecisive. It means you are growing and staying open to the idea that new information should replace outdated ideas. Science itself evolves, and so do you. The important thing is to stay active in the process, so you are not letting others make choices for you while you remain on the sidelines.

Mitochondria and the Role of Energy

One of the standout parts of our interview was discussing how health is tied to energy production within your cells. I have written extensively about mitochondria, the tiny power plants that convert nutrients into usable fuel, including in my book “Your Guide to Cellular Health: Unlocking the Science of Longevity and Joy.” As Gentempo and I both noted, many everyday toxins weaken this energy process, leaving you feeling drained or vulnerable to illness.

We also discussed the importance of removing known mitochondrial toxins. It is not enough to merely add good things, such as better foods and more movement, if you are still bombarding your cells with harmful substances.

That is like trying to sail a boat with an anchor dragging along the ocean floor. By freeing yourself from that anchor — say, by cutting out seed oils and reducing your exposure to endocrine-disrupting chemicals — you allow your body to generate energy more efficiently.

Gentempo’s philosophy rests on the idea that your body has an innate capacity for self-healing. I share that view. Through the years, many of the successes I have witnessed happened when patients embraced their responsibility to nurture their body’s innate wisdom. That meant exercising, eating foods free of damaging additives, and learning how to lower stress. It also meant staying curious instead of simply following the loudest or most “official” voice.

We recognize that tension often arises when you decide to break from the crowd. For example, during COVID-19 mandates, many people were torn between what made sense to them and what was required by policy. It was not our role in that discussion to dictate what is right for you. Rather, we suggest making decisions that are consistent with your core beliefs and the data you have gathered. That way, you avoid letting outside pressures force you into unwise or harmful choices.

Carrying the Lessons Forward

For me, interviewing Gentempo served as a reminder that the pursuit of health is not just about strict rules or scientific papers. It is about learning how to align what you know logically with what you feel intuitively. Studies and data hold great value, and I often cite them to support various points. Yet, you are the only one living in your body, experiencing your daily routine and coping with your unique challenges.

Gentempo explained that your mindset, emotions, and choices build your energetic field. And that, in turn, influences your physical reality. I support this view, especially after working with tens of thousands of individuals over the years who drastically improved their health by shifting daily habits — often starting with small, seemingly simple changes. They began by choosing to think differently about what health really means.

Our conversation finished on a hopeful note. Both of us see a massive need for a more authentic view of health, one driven by self-trust and curiosity rather than fear. This is your opportunity to make decisions that line up with what works for your body and your circumstances. As you do, you might spark curiosity in friends, family, or even strangers who see you living with more freedom and vitality.

Expanding Your Creative, Joyful Self

At the heart of everything we discussed is the idea that your life is meant to be creative, joyful, and free from unnecessary fear. I shared how your energy levels affect not only your physical strength but also your spirit. When you connect to that source of energy — whether you call it your spirit, soul, or simply your vital spark — you find that making the right health choices becomes easier.

Gentempo and I agree that real joy comes from living in alignment with your deepest truths. If you ever doubt whether your life can improve, I encourage you to consider the rapid transformations I have seen. Some people overcame serious health problems simply by questioning old assumptions and trusting themselves enough to try a different path. They created a ripple effect — changing not just their own health story, but also influencing others who noticed their results.

My hope is that you recognize how important it is to keep learning and growing. Stay curious about new findings in health, but always run them through your personal filter. Rely on your philosophy of wellness, continue refining your choices and remain open to future discoveries. Let that process fill you with the energy and clarity needed to embrace a life of true health and joy.

Moving Forward with Confidence and Vitality

As we wrapped up our interview, Gentempo shared the importance of embracing your own judgment and not being afraid to refine it as you learn. You are not stuck with a single belief system forever; you are free to change it when new evidence or personal experiences point you toward a better route.

You have a chance, right now, to take your health into your own hands by reflecting on the discussion I had with Gentempo. We covered everything from the power of your personal philosophy to the practical considerations of living in a system that often treats medicine as a universal cure-all. The message is not that you should reject every medical intervention, but that you need to see yourself as the central figure in your health journey.

I am thankful for the time I got to spend with Gentempo, as it reinforced the core principles I have championed for decades: Focus on prevention, respect your body’s natural intelligence, and do not let fear drive you. Instead, examine studies, seek expert opinions and, if you come to a different conclusion than the mainstream, realize that might be the best choice you ever make.

Elevating Your Health with Purpose

As my conversation with Gentempo explains, your health is best served by your own wisdom, guided by solid facts and a willingness to adapt. Neither of us suggests living in a bubble or ignoring doctors. Instead, we want to encourage you to become a partner in your own care — one who weighs information carefully and doesn’t forget the power you hold over your daily habits.

Through this collaboration between your knowledge and your intuition, you tap into a higher level of healing and growth. Recognize that “health care” should not be limited to an endless series of prescriptions. Rather, it is a dynamic, ongoing practice of fueling your body well, giving it enough rest, and choosing safe, evidence-based interventions when necessary.

I invite you to read more about the ideas we touched on. Explore Gentempo’s website, gentempo.com.2 Look up peer-reviewed studies on subjects that interest you. Pay attention to experts you trust, but always match their advice to your own situation. If something feels off or leads to negative outcomes for people you care about, dig deeper. Ask questions. Adjust your approach. That is how true learning happens.

I hope you use these insights to push past fear or confusion and step boldly into a life driven by your own inner compass. Like Gentempo, I believe you will find that once you tune in to your body’s capabilities — you unlock not just a healthier version of yourself but also a more joyful and meaningful life overall.

I spend a great deal of my time researching the science of nutrition and metabolism, but some of the most powerful lessons come from personal experience in the kitchen. Recently, I set out to make the healthiest possible chip — a rice and sweet potato cracker, baked in coconut oil with nothing but salt added. My domestic manager spent hours perfecting the recipe — rolling the dough thin enough, adjusting bake times, getting the salt level right.
They were thin, crispy, and genuinely delicious. The ingredients could not have been cleaner. Organic rice flour, sweet potato, coconut oil, and salt. No seed oils — the linoleic acid content came in at roughly 1%. No MSG, no flavor enhancers, no artificial anything. Baked, not fried. By any conventional measure, these were about as healthy as a snack can get.
And yet, I could eat the entire batch in one sitting without blinking. They were addictive in the truest sense of the word — the same compulsive hand-to-mouth behavior you see with Doritos or Lay’s. This troubled me, because I had the same experience with dehydrated zucchini chips — a pure vegetable, sliced thin and dried. Even with nothing added, they were irresistibly easy to overconsume.
Meanwhile, if you put a whole baked sweet potato or a bowl of watermelon in front of me, I eat a reasonable amount and stop. The satiety signals work. My body tells me when it’s had enough. But with the chips? That signal never comes — or it comes far too late. This personal observation sent me down a research rabbit hole. What I found has fundamentally changed how I think about processed food — and may change how you stock your kitchen. The implications go far beyond just chips.

The Processing Is the Addiction — Not the Ingredients

Most conversations about processed food focus on what’s been added — sugar, salt, seed oils, artificial flavors, preservatives. And those are legitimate concerns. But my chip experiment reveals something more fundamental: the physical transformation of whole food into a processed format is itself sufficient to create compulsive overconsumption, even when the ingredients are impeccable.

• The landmark study that crystallized this was a 2019 trial at the National Institutes of Health (NIH) — For the study, published in Cell Metabolism, researchers admitted 20 adults to the NIH Clinical Center and randomized them to receive either ultraprocessed or unprocessed diets for two weeks, immediately followed by the alternate diet. Here’s the key detail — the meals were matched for presented calories, energy density, macronutrients, sugar, sodium, and fiber.1
• The results were striking — Participants consumed about 508 additional calories per day on the ultraprocessed diet, gained weight during that period, and lost weight during the unprocessed diet period. The foods were nutritionally equivalent on paper — what differed was the physical form and degree of processing.

While this study compared entire dietary patterns rather than individual food textures, it established the principle that processing level — independent of nutrient content — drives overconsumption. Later research pinpointed texture as a key mechanism.

Why Your Brain Can’t Say No to the Crunch

When a chip shatters between your teeth, the crunch travels through your jawbone directly to your inner ear — a miniature sonic event your brain finds deeply satisfying. There’s essentially nothing in nature that provides this specific type of dry, brittle, explosive fracture. Natural crunchy foods — raw carrots, celery, apples — have a wet, fibrous crunch that requires significant jaw force. The dry chip crunch is a fundamentally different sensory event.

• Your brain evolved to find these textures highly rewarding — In ancestral environments, dry, calorie-dense, shelf-stable foods were rare and enormously valuable.
• The sensory system that makes you seek out that crunch was an adaptive advantage — Such foods required days of sun-drying, hand-grinding, and preparation. Now that same system is being exploited by a food format that can be produced in unlimited quantities.

Food Texture Controls How Much You Eat

It turns out my kitchen experiment mirrors what researchers found when they tested this formally. In a 2022 crossover study published in the American Journal of Clinical Nutrition, 50 healthy-weight participants were given four different lunch meals — varying in both texture and processing level — and allowed to eat as much as they wanted:2

◦ Soft minimally processed
◦ Hard minimally processed
◦ Soft ultraprocessed
◦ Hard ultraprocessed

• The harder-textured meals were consumed more slowly — They also produced roughly a 21% to 26% reduction in both food weight and energy consumed. The least energy came from the hard minimally processed meal (about 483 kcal), and the most from the soft ultraprocessed meal (about 789 kcal) — a difference of approximately 300 calories from a single meal. Softer textures and higher processing levels likely made the food easier and faster to eat.
• This finding has been replicated consistently — A 2024 study in the British Journal of Nutrition tested 24 different meals and found that slower-textured meals consistently reduced food intake by about 22%, with a 20% decrease in eating rate producing approximately an 11% decrease in energy consumed.3 The effect held across every meal type tested — breakfast and lunch, across a wide variety of foods.
• Foods designed for rapid eating quietly increase total calorie intake — Research published in Nature Food examined 2,733 individual meals across four dietary patterns and found that energy density, eating rate, and hyper-palatability consistently predicted higher energy intake across all diets.4 The faster a food could be consumed, the more calories people ate.

The 4 Mechanisms of the Chip Trap

When you dehydrate and process a whole food into a thin, crispy chip — even from the healthiest ingredients — you simultaneously trigger four mechanisms that bypass satiety. These mechanisms don’t just add up — they multiply each other. Each one makes the others worse, which is why the chip format is so disproportionately effective at overriding your body’s built-in controls:

• First, you concentrate calories by removing water — A whole sweet potato is roughly 77% water. When you eat it, your stomach fills with volume, stretch receptors fire, and satiety hormones are released. A chip made from that same sweet potato has had most of that water removed.
You consume the caloric equivalent of several sweet potatoes in a fraction of the stomach volume. The stretch receptors embedded in your stomach wall — one of your body’s primary “I’ve had enough” signals — barely register the intake.
• Second, you eliminate chewing resistance — A whole sweet potato requires sustained chewing — multiple chew cycles per bite, mixing with saliva, conscious swallowing. This slow oral processing gives your satiety signaling time to keep pace with intake.
A thin chip dissolves in three to five chews. The oral transit time is so short that your brain’s satiety cascade — the chain of hormonal signals that builds fullness in stages, from your gut to your brain — can’t keep up with your hand-to-mouth pace.
• Third, you create rapid oral dissolution — Food scientists have documented what’s called the “vanishing caloric density” phenomenon. When a food dissolves or fractures rapidly in the mouth, the brain partially discounts the calories. The sensory system interprets rapid oral clearance as lower energy density than the food actually contains. The chips are calorie-dense but sensorially “light.”
In other words, your brain uses oral texture as a rough calorie meter — when food melts away quickly, your brain reads it as low-energy, like broth or lettuce, even when it’s calorically dense. It’s essentially a sensory accounting error.
• Fourth, you create a rapid reward cycle — Each crunch generates a small dopaminergic reward signal — a small burst of dopamine, the same neurotransmitter involved in the pleasure response to sugar or social media notifications.
The chip is gone in seconds, the reward fades, and your hand reaches for the next one. The cycle time from reward to seeking to reward is perhaps five to 10 seconds per chip. Compare that to eating watermelon, where each bite involves cutting, picking up, biting through rind, and chewing through fibrous flesh.

The Dehydration Experiment Confirms It

My experience with zucchini chips was equally instructive. Zucchini is about as benign a vegetable as exists — low-calorie, high water content, minimal sugar. But sliced thin and dehydrated, it becomes compulsively overeatable. Fortunately, zucchini isn’t particularly calorie-dense even when dehydrated, so the health consequences are modest. But the behavioral pattern is identical to the rice-sweet potato chips.
This confirms that the addiction mechanism is the physical format, not the macronutrient composition. You don’t need sugar, fat, salt, or any combination thereof to create compulsive eating behavior. You need only remove water, remove structural integrity, and create rapid oral dissolution.

The Uncomfortable Truth About ‘Healthy’ Snacks

I now believe that there is no such thing as a healthy chip. It doesn’t matter if you buy them at Whole Foods, Sprouts, or make them in your own home from the healthiest ingredients.
The chip format itself — thin, dry, calorie-dense relative to volume, rapidly dissolving — is metabolically adversarial regardless of ingredient quality. Calling something a “healthy chip” is a contradiction in terms, much like “healthy cigarette.” You can improve the ingredients, but the delivery mechanism is inherently problematic.

• Engineered food combinations dominate the modern U.S. food supply — Hyper-palatable foods — foods engineered with specific combinations of fat, sugar, salt, and carbohydrates that excessively activate brain reward systems — are pervasive in the U.S. food system.5
• A food system shaped by local production offers built-in protection — A 2024 study in Frontiers in Nutrition compared the food systems of Italy and the U.S. to understand how local food production practices shape what ends up on shelves.6 In Italy, which has largely resisted the dominance of multinational food corporations, less than a third of available foods met the threshold for hyper-palatability.
When researchers compared similar products across both countries — cookies, salty snacks, frozen pizza, protein bars — the American versions consistently contained significantly more fat, sugar, and sodium, while the Italian versions contained more fiber and protein, nutrients that promote satiety rather than override it.
The takeaway isn’t that Italian food is inherently virtuous — it’s that a food system built around local production, rather than engineered mass-market products, naturally produces foods that are less likely to hijack your appetite.
• Physical form alone can make foods difficult to stop eating — My experience goes further than even the hyper-palatability research suggests. My chips had none of the engineered combinations that define hyper-palatable food. They were addictive purely through their physical form.
• Food texture and structure shape how much people consume — Researchers writing in Current Nutrition Reports have made the broader case that food form, texture, and matrix — not just composition — are primary determinants of energy intake and metabolic response.7 Their review demonstrates that the way a food is physically structured matters as much or more than what it contains.

What This Means for Your Kitchen

The practical takeaway is straightforward but difficult to accept: if you’re trying to optimize your health, avoid the chip and cracker format entirely, even when made from whole, organic, minimally processed ingredients at home. The effort and energy required to make them at home (my domestic manager can attest to this) is itself a clue.
In nature, the processing energy required to turn a sweet potato into a dehydrated cracker would have been enormous — days of sun-drying and hand-grinding. That energy barrier was a natural throttle on consumption that modern kitchens have eliminated. Before eating any snack, ask yourself: does this require real chewing, or does it dissolve? If it dissolves, your satiety system is essentially flying blind. Instead:

• Eat your sweet potatoes whole; try baked sweet potato wedges with the skin on — the moisture and fiber remain intact
• Eat your zucchini steamed or raw
• Eat your rice as cooked rice
• If you crave crunch, cucumber slices with the skin on provide mechanical resistance without the calorie concentration

Keep the water in, keep the fiber intact, keep the structural complexity that forces your jaw to work and your satiety system to function as designed. The path to health runs through whole foods in their natural, water-containing, structurally complex form — not through finding ever-more-clever ways to turn them into chips.

FAQs About Why Crispy Snack Foods Are So Easy to Overeat

Q: Why are homemade chips made from healthy ingredients still easy to overeat?
A: Even when chips are made from clean ingredients such as sweet potatoes, rice flour, coconut oil, and salt, their physical structure changes how your brain and body respond to them. Removing water concentrates calories and creates a thin, crispy texture that dissolves quickly in your mouth, allowing you to eat large amounts before satiety signals catch up. Research shows that the physical form of food — not just the ingredients — strongly influences how much people eat.

Q: How does food processing affect how many calories people eat?
A: Research shows that people naturally eat far more calories when foods are highly processed, even when the meals appear nutritionally similar. In a tightly controlled clinical study, participants consumed about 508 additional calories per day when eating an ultraprocessed diet compared with a minimally processed one.8
The meals were carefully matched for calories, fat, sugar, sodium, and fiber, yet participants still ate significantly more of the processed foods and gained weight during that phase of the experiment. These findings suggest that the structure and processing of food — not just its nutrient content — strongly influence how much people eat.

Q: How does food texture influence how much you eat?
A: Texture affects eating speed and satiety. In one study, harder-textured meals caused participants to eat more slowly and consume significantly fewer calories — up to about 300 fewer calories in a single meal compared with softer foods.9 Slower eating allows the body’s satiety signals to activate before large amounts of food are consumed.

Q: Why can drying or dehydrating a whole food make it easier to overeat?
A: Drying a food removes most of its water, which dramatically concentrates its calories while reducing the volume that fills your stomach. A whole sweet potato, for example, is roughly 77% water and creates substantial stomach stretch when eaten intact.
When that same food is dehydrated into thin chips, much of that volume disappears, allowing the calories from several sweet potatoes to be consumed in a much smaller portion. The chip format also reduces chewing time and speeds up eating, which gives your body less time to trigger fullness signals. Together, these changes make dehydrated foods much easier to overeat than their whole, water-rich counterparts.

Q: What practical lesson does this research suggest for everyday eating?
A: The evidence suggests that whole foods in their natural, water-rich and structurally intact form are easier for your body to regulate. Foods that retain moisture and require chewing — such as whole vegetables and fruit — slow eating and promote satiety. In contrast, dehydrated, crispy foods concentrate calories and can be consumed rapidly, increasing the likelihood of overeating.

Most patients with chronic pain will typically first be recommended a variety of pain medications and physical therapy, then once those fail, steroid injections, and then a joint surgery.

Unfortunately, each step in this process is often ineffective at addressing the patient’s pain or creates a variety of complications that make their situation even more unbearable. For this reason, it is critical to understand the risks of each part of this process and the safer alternatives that can permanently alleviate joint and spinal pain.

Note: Persistent or recurrent pain after spinal surgery, back pain following spinal surgery is referred to as “Failed Back Surgery Syndrome” and affects between 10% to 40% of people who receive a spinal surgery.

Common Spinal Pain Generators

In most cases, joint pain has a cause that needs to be identified to treat it. For example, when treating spinal pain, we find it is critical to address:

• Tight muscles — Rarely recognized despite being common (particularly of the iliopsoas and quadratus lumborum — two large and frequently tight muscle groups which directly attach to the lumbar spine). Physical therapists typically focus on strengthening rather than stretching/releasing tight muscles.

• Misalignment — Requires adjustment and lifestyle corrections. A common cause of misalignment are uneven leg lengths which tilt the pelvis and hence the spine (and can be corrected with an appropriate heel lift).

• Ligamentous laxity — Often the primary cause of spinal arthritis, muscle tightness, and disc problems as tight ligaments are necessary to ensure bones stay in the correct location and do not impinge tissues.

• Disc herniation — Not the most common cause of back pain but sometimes a significant contributor (and frequently used as a justification for disastrous spinal surgeries). In most cases, disc herniations result from vertebrae bending too far forward, which pushes the discs back and compresses the nerves behind them.

This can frequently result from a weakening of the spinal ligaments or poor posture which eliminates the natural backwards curve in the neck and low back.

Note: Tight muscles, joint misalignments, and ligamentous laxity also create issues in other regions of the body (e.g., the knees).

Additional Pain Generators

• Trapped emotions — Chronic stress and emotional distress frequently exacerbate pain (and in some cases are the primary cause of back pain). Dr. Sarno for example, addressed back pain through psychotherapy and generated a large following1 as his approach helped many (but not everyone).

Note: We frequently find a direct release of trapped emotions (rather than psychotherapy) is necessary to address chronic emotional trauma.

• Nervous system dysregulation — Over-activation of the sympathetic nervous system alongside under-activation of the parasympathetic system exacerbates pain.

Note: A common effect of unresolved trauma is fight-or-flight system over-activation.2

• Chronic inflammatory conditions (e.g., dietary allergies, mold toxicity, Lyme disease, spike protein injuries) often worsen pain patterns.

Note: Many individuals have found that eliminating dietary food allergens resolves arthritis.

• Scars from surgeries can frequently generate significant autonomic dysregulation and pain, and frequently, treatment of those scars yields dramatic improvements.

• Altered brain pain processing — Often due to chronically over-activated nerves or microstroke injuring the thalamus (which otherwise dampens pain signals).3 In these instances, small stimuli can be extremely painful.

Systemic Medications

Since joint or spinal pain has multiple causes and diagnosis is time-consuming, physicians typically prescribe pills or refer patients elsewhere rather than address the root causes of their pain. Common medications include NSAIDs, Tylenol, Steroids, Gabapentin (or Lyrica), and Opioids — all with major issues.

Note: Due to the high rate of addiction which follows opioid prescriptions (and the societal damage that follows), more and more, the government has moved to restrict opioid prescriptions. Because of this, patients in significant pain who will only respond to opioids, despite their best efforts, often cannot get these drugs and instead are given another ineffective option (e.g., NSAIDs), hence making it imperative that effective non-opioid solutions for pain be made available to the public.

• NSAIDs — NSAIDs (e.g., ibuprofen, naproxen) temporarily reduce pain but only partially, leading patients to overuse them — often dangerously, as NSAIDs are toxic at high doses (which frequently occur since NSAIDs are taken for pain and are available over the counter). Many consider NSAIDs among the most hazardous drugs in the U.S. because:

◦ They are the leading cause of drug-related hospital admissions — Often due to heart attacks, strokes, bleeding, and kidney failure.4

◦ Kidney damage is a significant risk — One study found a 20% increased risk of kidney disease from NSAIDs;5 others found up to 212%.6 Amongst kidney failure patients, 65.7% were found to be chronic NSAID users.7

◦ NSAIDs raise cardiovascular risks — NSAIDs also increase the risk of heart attacks and death (e.g., extensive studies have found between a 24% to 326% increase8,9,10). Two of the worst ones, Vioxx (Merck) and Celebrex (Pfizer), were designed to reduce stomach bleeding but instead caused heart attacks and strokes.

Merck hid data on Vioxx’s risks; eventually it was withdrawn after an estimated 120,000 deaths.11 Celebrex, still on the market, has been linked to 75,000 deaths.12 Merck’s handling of Vioxx13 later informed how pharma pushed the HPV vaccine14 and mRNA vaccines.

Note: A year before Vioxx hit the market, Dr. Mercola warned about its clear dangers, but was ignored.

◦ Gastrointestinal bleeding is common and often fatal — In 1999, over 16,000 Americans died from it.15 NSAIDs also cause small bowel damage in over 50% of chronic users16 — often undetected — leading to “small bowel enteropathy” and possibly chronic illness through gut permeability.17

◦ They impair healing, especially of ligaments, creating long-term re-injury risk.18

“Trials alleging the benefit of NSAIDs are frequently intentionally deceptive and frequently create the illusion of a benefit where none exists. What this means is that many patients ruin their lives with drugs that did almost nothing for them in the first place.” — Peter Gøtzsche19

Unfortunately, NSAIDs remain amongst the most commonly prescribed drugs, and are frequently given for musculoskeletal injuries.

Note: The dangers of NSAIDs are discussed further here.

• Tylenol — Tylenol (acetaminophen) is one of the few over-the-counter alternatives to NSAIDs and is generally considered safer, though often ineffective for severe pain. Still, it carries serious risks:

◦ Liver toxicity — Overuse leads to 56,000 ER visits, 2,600 hospitalizations, and 500 deaths annually in the U.S. due to Tylenol toxicity.20

◦ Fever suppression — Tylenol reduces fevers, which are key immune defenses. Suppressing them can worsen or prolong infections — a pattern observed during COVID-19.21 Many parents of vaccine-injured children reported symptoms (e.g., autism) appeared after using Tylenol to suppress high post-vaccine fevers, explored in this 2021 paper.22

• Gabapentin and pregabalin — Gabapentin (Neurontin) was originally approved to treat epilepsy — a small market. After approval, Pfizer aggressively pushed it for unapproved uses, especially neuropathic pain, despite limited evidence.23 The federal government fined Pfizer nearly $1 billion for illegal promotion.

While less toxic than NSAIDs, side effects for these drugs are common and include: lethargy, dizziness, sedation, and cognitive impairment, as well as rarer but serious reactions like respiratory depression and hypersensitivity. Gabapentin can also be habit forming.

Note: Since gabapentin and pregabalin (Lyrica) only work for specific types of pain (e.g., neuropathic pain), they typically do very little for most patients’ pain. However, they are widely prescribed because they lack many of the severe risks associated with other pain reducing drugs, and as a result, many are placed on inappropriate prescriptions for them.

• Corticosteroids — Initially hailed as a wonder drug, corticosteroids like prednisone and hydrocortisone gradually were discovered to have significant side effects (e.g., weight gain, adrenal suppression, heart attacks, diabetes, insomnia, and psychiatric effects). Since corticosteroids trigger tissue breakdown, they also often greatly weaken the body’s structural integrity, impair wound healing and weaken collagen synthesis.24

Furthermore, corticosteroids double one’s risk of fracture (especially vertebrae),25 with 12% of users reporting fractures.26 Steroids cause 5% to 15% bone loss yearly,27 and 37% of long-term users experience vertebral fractures.28 High doses increase vertebral fracture risk fivefold.29 Higher doses also cause avascular necrosis in 6.7% of users.30

Note: The primary drugs used to treat Osteoporosis (bisphosphonates) have severe side effects including making the bones more likely to break. In turn, one of the few approved uses for bisphosphonates is steroid-induced bone loss.31

Since both collagen, ligaments (which are composed of collagen), and bones are weakened by steroids, chronic use leads to joint weakening and chronic pain. Because of this, we frequently encounter patients who achieved a temporary alleviation of joint pain (e.g., in the spine or knee) who then have their condition worsen and require surgery. Unfortunately, this side effect is rarely disclosed to patients, leading to many surgeries that could have been prevented.

Note: In many cases, if joint pain is instead treated by strengthening the ligaments (e.g., with nutritional supplementation or prolotherapy), the pain will resolve and future surgeries can be prevented.

The Surgery Funnel

Surgeries often have risks that patients don’t learn about until after complications occur, which is problematic since you can’t “undo” surgery. For this reason, patients should seek unbiased second opinions from doctors who aren’t being paid to do a proposed surgery.

Unbearable pain (e.g., in a joint) is one of the strongest motivators for surgery, and spinal surgeries are the most common elective surgery I’m consulted about. Unfortunately, since spinal surgeries are one of the most profitable areas in medicine,32 there’s reluctance to consider if risks outweigh benefits or if safer and more effective alternative exist, and over the years I’ve become increasingly skeptical of them.

Likewise, despite trillions spent on spinal pain (e.g., in 2016, 134.4 billion dollars was spent on neck and low back pain in the USA),33 most patients remain stuck with chronic pain and experience significant side effects from treatments.

Note: There have been numerous newspaper investigations of spinal surgeons who recklessly performed large volumes of unnecessary surgeries,34 killing or injuring many of their patients who were nonetheless protected by their hospitals because of how much revenue they generated.

DMSO — A Safer Alternative

Over the last seven months, I have been working to spread awareness of dimethyl sulfoxide to the world, a natural compound which provides dramatic benefit for a variety of challenging conditions (e.g., autoimmunity, strokes, paralysis, antibiotic resistant infections, cancers, vision loss, and tinnitus).

DMSO also increases blood circulation to tissue, reduces inflammation, interrupts pain transmission, relaxes muscles, and decreases activity of the sympathetic nervous system.35 Because of this, DMSO is highly effective at:

• Healing tissue injury (including paralyzing spinal cord injuries).

• Treating bursitis.

• Healing arthritis.

• Reducing acute and chronic pain.

• Treating many forms of pain, conventional therapies (including opioids) are often ineffective for such as cancer pain, complex regional pain syndrome, fibromyalgia, post-surgical pain and phantom limb pain.

For example, in this article, I summarized dozens of studies (comprising thousands of patients) which consistently showed DMSO improved the majority of musculoskeletal conditions it was tested on (e.g., one of 38 patients with lumbar and disc herniations that found DMSO made them recover twice as quickly).36

Likewise, I have now received thousands of remarkable testimonials from readers who used DMSO, most of which were of a significant improvement in pain or rapid healing of an injury.37 Likewise, many doctors such as James Miller MD have been inspired to use it in their practice and seen similar remarkable results for a variety of challenging conditions.

Here one doctor, James Miller details the unbelievable results he’s seen in so many conditions over the last few months since he started using it (e.g., a patient needing a transplant getting her lungs back). pic.twitter.com/HpuO4m7Ppf— A Midwestern Doctor (@MidwesternDoc) April 25, 2025

For musculoskeletal injuries (e.g., pain or injuries), in most instances where a steroid or NSAID would be used, we find DMSO:

• Is more effective at addressing the immediate issues.

• Also heals the underlying issue (e.g., a herniated disc or injured ligament) rather than worsening it and creating future musculoskeletal injuries.

• Does not have the myriad of (often severe) side effects frequently seen from standard treatment options.

As such, for years, we’ve found that in most cases where drugs like NSAIDs are widely used, much better and far safer results could be obtained from DMSO. Unfortunately, while this was recognized in the past (e.g., many professional athletes in the 1960s and 1970s found DMSO dramatically improved their ability to recover from injuries and facilitated rapid returns to the field), all of that has now been largely forgotten. Consider for example, this 1980 60 Minutes episode:

In the 1960s a miraculous treatment for chronic pain, traumatic injury, strokes and spinal cord paralysis was discovered that spread across America like wildfire—until the FDA buried it.Here, 60 Minutes exposed the FDA using the same playbook they used throughout COVID-19.

Conclusion

The medical business model revolves around maximizing sales, either by perpetually selling a patient medications or by funneling them into high ticket items, and as I’ve tried to show here, pain management exemplifies this business model.

For instance, spinal surgeries (the last step for many patients whose pain was improperly managed), can make a hospital well over $100,000 each. In turn, as an investigation of numerous botched neurosurgeries showed, ambitious neurosurgeons (e.g., those who wanted to do so many surgeries they would often have multiple operating rooms running concurrently) will make enough money to sustain a hospital:38

Similarly, as this article showed, patients with chronic pain are often put onto lifelong prescriptions of pain medications which fail to address much of their pain, have significant (and sometimes life-threatening) side effects, and frequently force them down the sales funnel to the lucrative joint and spine surgeries.

That predatory business model in turn, was exemplified by Purdue Pharma, which bribed an FDA reviewer to claim their proprietary opioid (OxyContin) was not addictive.39 In 1995, the drug was then marketed with that claim and having the American Pain Society declare “pain was the 5th vital sign,”40 compelling doctors to routinely assess for it and treat any existing pain with opioids (as otherwise they faced malpractice investigations from state medical boards).

This, in turn, created the modern opioid crisis (as many opioid users develop permanent addictions after brief courses of these “non-addictive” drugs) which eventually affected so many communities doctors lost much of their ability to prescribe opioids to patients with crippling pain nothing else worked on.

In my eyes, the root cause of all of this is that since pain is an ideal market, there is very little interest in looking at either the shortcomings of existing treatments or looking into actual treatments for pain which destroy that perpetual revenue stream.

Fortunately, the need to reduce wasteful spending (e.g., for costly and unnecessary surgery) MAHA moment is at last giving us a chance to change things and begin looking at the actual causes and treatments for these conditions rather than costly ones that do neither.

If you’ve ever finished a workout and wondered why your mind still feels foggy instead of sharp, your fitness level may be the reason. A 2026 study published in Brain Research found that your brain doesn’t respond to exercise the same way when you’re out of shape.1 Exercise triggers the release of brain-derived neurotrophic factor (BDNF), a protein that works like fertilizer for your brain.
Just as fertilizer helps roots grow stronger and deeper, BDNF strengthens the connections between brain cells, helping you think more clearly, focus longer, and adapt faster. But how much BDNF your brain produces during a workout depends heavily on your fitness level. For anyone dealing with mental fatigue, poor focus, or slower thinking, this insight hits close to home.
You read the same paragraph three times. You lose your train of thought mid-sentence in a meeting. You reach for coffee at 2 p.m. not because you’re tired, but because your brain feels like it’s running through mud. These symptoms often reflect reduced efficiency in the prefrontal cortex, the part of your brain that handles concentration, impulse control, and complex tasks. When this system underperforms, daily work feels harder, distractions increase, and decision-making suffers.
Left unchecked, this decline in cognitive sharpness affects productivity, mood, and long-term brain resilience. What becomes clear is that exercise alone isn’t the full story — your level of fitness determines how powerful that exercise becomes for your brain. Here’s what the research found — and why it changes the way you should think about every workout.

Getting Fitter Rewires How Your Brain Responds to Exercise

The Brain Research study followed sedentary adults through a 12-week cycling program to see how exercise changes the brain’s response to physical activity.2 Researchers tracked three things simultaneously: BDNF levels, cognitive performance, and real-time brain activity using neuroimaging. The goal was to find out whether getting in shape changes how your brain reacts during exercise, not just over time but in the moment you move.
The study included adults who exercised less than 30 minutes a day and placed them into two groups: one completed a structured cycling program, while the other stayed inactive. The training group gradually increased intensity from light to more demanding sessions.
By the end, their cardiovascular fitness improved significantly, as measured by VO2 max — essentially a score for how efficiently your heart, lungs, and muscles use oxygen during exertion. The higher your VO2 max, the more capacity your body has to fuel both physical and mental performance. The control group showed no improvement. That distinction set up a clear comparison between a “trained” and “untrained” brain response.

• Fitness changed how strongly the brain responded during exercise — The biggest shift appeared not at rest, but during exertion. After 12 weeks, the trained group showed a significant increase in serum BDNF only after intense exercise, not before it.
This means your brain doesn’t upgrade its response until you build a stronger engine. The more fit participants became, the larger the spike in this brain-supporting protein when they exercised. Researchers confirmed this link by showing a direct correlation between improved fitness scores and higher BDNF increases.
• Higher fitness translated into measurable brain performance changes — Alongside these biological changes, participants improved how their brains handled tasks that require focus and control. Reaction times dropped, meaning faster thinking, and performance improved on attention and inhibition tasks — the kind of mental skills you rely on to stay focused and avoid distractions.
These gains showed up consistently after exercise sessions — direct evidence that a fitter body produces a sharper mind in real time. Using brain imaging, the study also tracked activity in the prefrontal cortex — the area responsible for decision-making, attention, and impulse control.
As BDNF increased, activity patterns in this region shifted during tasks that required focus and inhibition. In plain terms, your brain became more efficient at handling demanding mental work after exercise, especially once you were fitter.
• Timing mattered — results only appeared after consistent training — Interestingly, the benefits didn’t show up halfway through the program. At week 6, there was no meaningful connection between fitness gains and BDNF response. During those early weeks, your body is building the cardiovascular infrastructure, like stronger blood vessels, more efficient oxygen delivery, and improved mitochondrial function, that eventually allows your brain to produce a stronger BDNF response.
Only after the full 12 weeks did the effect become clear. That tells you something important: your brain doesn’t always respond instantly to lifestyle changes. It adapts gradually, and the payoff comes after sustained effort. If progress feels slow early on, that is part of the process, not a failure.
• The strongest effects showed up in those who improved the most — Participants who reached higher fitness levels saw the largest increases in BDNF after exercise. This creates a self-reinforcing cycle: higher fitness triggers a stronger brain response, which sharpens your thinking and focus, which makes staying consistent with training feel less like willpower and more like momentum. You aren’t just building endurance — you’re building a brain that responds more efficiently to every effort.
• Different forms of this brain protein serve different roles — The researchers measured two types of BDNF: plasma BDNF and serum BDNF. Think of plasma BDNF as your brain’s quick-release dose — it spikes right after you move. Serum BDNF reflects your body’s deeper reserves, how much of this protein your system is capable of manufacturing and storing. The key finding was that fitness expanded those reserves, so fitter people had a bigger supply to draw from each time they exercised.
BDNF supports several key processes inside your brain: it improves blood flow, strengthens connections between brain cells, and supports energy production at the cellular level. As your fitness improves, your body amplifies this response, delivering more resources to the parts of your brain that handle complex thinking. That is why the same workout produces stronger mental benefits once you’re in better shape.

Build Your Fitness to Unlock Your Brain’s Full Potential

So, what does this mean for your daily routine? Your brain doesn’t fully respond to exercise until your body reaches a higher level of fitness. That’s the root issue. If your workouts are inconsistent or your mental clarity doesn’t improve, the missing piece isn’t effort — it’s adaptation.
Once your fitness improves, your brain produces stronger signals that sharpen focus, speed up thinking, and improve control. That means the goal isn’t random exercise. The goal is building capacity over time so your brain starts working with you instead of against you.

1. Commit to a 12-week progression, not random workouts — If you jump between routines or stop after a few weeks, your brain won’t reach the point where it upgrades its response. The research shows the real shift happens around the 12-week mark. Set a simple rule: train consistently for three months before judging results. Track your sessions like a scoreboard. Each completed workout is a point. The goal is consistency, not perfection.
2. Train across intensities to improve your results — Your brain responds more when your body faces a range of demands. Include low, moderate, and high-effort sessions each week. For example, mix easy sessions where you can talk comfortably with harder sessions where your breathing becomes heavy.
A routine that includes walking, strength training, heart-rate-raising movement, and coordination provides full-body benefits. This variety pushes your system to adapt, which strengthens the brain response tied to focus and decision-making.
3. Measure progress using effort and capacity, not just time — Fitness isn’t about how long you move — it’s about how your body performs. Pay attention to how hard a workout feels and how quickly you recover. If you notice that the same workout feels easier over time, your fitness is improving. That improvement is what drives the stronger brain response seen in the research.
4. Start with walking and build gradually without overdoing intensity — Daily walking works as a powerful entry point because it improves mood regulation and energy production without placing excessive stress on your system. If you’re new to exercise, start small. Add five minutes each week until you reach 30 minutes, then hold that level for a month before building toward one hour a day.
Avoid pushing intense exercise too frequently. Pounding yourself with hard workouts too often backfires and slows progress.
5. Use post-exercise focus as feedback that you’re on the right track — After a workout, pay attention to how your mind feels. Sharper thinking, better focus, and quicker reactions signal that your brain is responding. Early on, this effect might feel weak. As your fitness improves, it becomes stronger and more noticeable.
That is your real-time proof that your efforts are working. Stick with this long enough and your workouts stop feeling like a chore. They become a tool that sharpens how you think, how you make decisions, and how you perform every day.

FAQs About How Exercise Improves Your Brain Function

Q: Why doesn’t exercise improve my brain function right away?
A: Your brain doesn’t upgrade its response immediately because it depends on your fitness level, not just the act of exercising. The research shows that stronger brain benefits — including higher BDNF release — only appear after consistent training over about 12 weeks. Early workouts still matter, but the real shift happens once your body adapts and becomes more efficient.

Q: What is BDNF and why does it matter for my brain?
A: BDNF is a protein that supports brain cell growth, communication, and energy use. It acts like a signal that helps your brain become faster, sharper, and more resilient. Higher levels during exercise are linked to better focus, quicker thinking, and improved control over distractions.

Q: How does being more fit change the way your brain works?
A: As your fitness improves, your brain produces a stronger BDNF response during exercise. This leads to better performance on tasks that require attention, decision-making, and impulse control. The same workout becomes more powerful for your brain once you’re in better shape.

Q: How long does it take to see real brain benefits from exercise?
A: The study found no meaningful changes halfway through the program at six weeks. The major improvements showed up after 12 weeks of consistent training. This timeline highlights that your brain adapts gradually, and the benefits build over time with steady effort.

Q: What’s the best way to start improving brain benefits from exercise?
A: Start with consistent movement and build gradually. Daily walking is an effective entry point because it improves energy and mood without overwhelming your system. As your fitness improves, add variety and intensity in a balanced way. The key is staying consistent long enough for your brain to adapt and respond more strongly.

When you can’t touch your toes, it signals a breakdown in how your body moves, stabilizes, and protects itself. That restriction doesn’t stay local. Over time, it pulls on your lower back, tightens your hips, and throws off the balance of your entire spine. What looks like a simple flexibility issue is often the first clue that your nervous system no longer feels safe allowing full range of motion.

Touching your toes isn’t just about stretching your legs. It’s about restoring the natural coordination between your muscles, joints, breath, and brain. The good news is, you don’t need an hour-long yoga session or a gym membership to do it. Newer protocols — like the ones you’ll see here — use breathwork, postural resets, and short daily movement cues to quickly reprogram your body’s response to stretching. These methods focus on safety, not strain.

What’s most exciting is how fast the improvements start to show. Meaningful flexibility gains happen in just minutes a day. These aren’t passive, forceful stretches. They’re targeted strategies that teach your body to move better and feel more supported, with less pain and more control.

In the sections ahead, you’ll see how three different sources each approached the same goal — improving toe-touch flexibility — but did it through different techniques. Whether you’re a beginner, dealing with pain or just want to move better as you age, lasting change doesn’t take long, it takes the right kind of repetition.

2 Minutes a Day Is Enough to Rebuild Flexibility

According to a feature in Fit & Well, mobility coach Roger Frampton has developed a minimalist routine designed to improve flexibility, spinal mobility and functional movement patterns in just two minutes per day.1 The goal is to retrain your body to hinge, fold, and move in ways it was designed to do. Touching your toes is about more than flexibility; it’s a full-body coordination test that reveals tightness and mechanical breakdowns up and down the back side of your body.

• Tight hamstrings don’t always mean you’re doing something wrong — Frampton points out that many people who are physically strong or active, such as runners, develop shortened hamstrings as a result of their specific sport.

“Your hamstrings have become tight for a purpose: to make you more springy when you run,” he explains. So, the goal of improving flexibility isn’t to undo this, but to balance strength with range of motion. The key is knowing when limited flexibility is protective and when it’s restrictive.

• The toe-touch test works as a self-assessment tool — Rather than labeling yourself as “inflexible,” Frampton recommends using a structured way to measure your flexibility over time. He suggests doing a toe-touch test first thing in the morning, with three specific rules: feet together, legs straight, and no warm-up beforehand.

This gives you a consistent baseline. Track improvement by marking how far down your hands reach on your legs, or even against props like a boot or chair. Gamifying the test taps into motivation and self-efficacy.

• A simple 30-second floor drill improves results immediately — The routine itself is shockingly easy. Sit on the floor with your legs straight and press your knees down. Try to lift your heels off the ground while reaching forward and hold for 30 seconds.

If that’s too hard, place a book under your knees. Then stand up and repeat the toe-touch test. “Hopefully you’ve got a lower mark,” Frampton says, meaning you reached farther down in just one round. He recommends doing three sets of this each day.

• Stacking micro-practices helps rewire movement without overloading your brain — This 30-second drill is effective because it combines spinal flexion, hamstring lengthening, and nervous system retraining in one compact movement.

When practiced daily, your body adapts quickly, without needing long sessions or formal workouts. That makes this method especially useful if you’re short on time, recovering from stiffness, or overwhelmed by complex exercise routines.

• Frampton’s method uses hinge mechanics to correct movement patterns at the root — One of the foundational exercises involves holding a broomstick along your spine to learn how to bend from your hips rather than rounding your back.

This teaches proper hip hinge movement, which is essential for injury prevention, lifting and athletic function. It also shifts the effort away from your lower back and builds a safer, more balanced movement pattern that supports long-term flexibility.

The Real Fix Isn’t More Stretching, It’s Rewiring How You Move

If you’ve ever felt like stretching doesn’t work for you, you’re not alone — and you’re not broken. The problem usually isn’t your muscles. It’s the way your nervous system has adapted to poor posture, shallow breathing, and overcompensation patterns. That’s why stretching harder often backfires. The real solution is to retrain how your body organizes movement. And according to physical therapist and strength coach Zac Cupples, that starts with your breath.

Cupples created a step-by-step flexibility protocol that zeroes in on your core’s alignment and breathing mechanics, not just hamstring length. His approach uses short, specific exercises to build not just mobility but trust in your own body again.2

• Start with the “lower rib and pubic bone press” to reset your breathing and core engagement — Lie face down with a soft pad or pillow under your ribs and pelvis. Stretch one arm and the opposite leg out to the side, keeping the other arm tucked by your chest and that same-side knee bent.

Turn your head toward the outstretched arm. Now inhale slowly through your nose and exhale gently through your mouth. As you breathe out, press slightly into the ground with your elbow and knee to lift your chest — just a little — without losing contact with the pillow. Hold for five breaths and repeat four sets on each side daily.

• Use the “back muscle relaxer” to decompress your spine and reduce back tension — If your lower back feels tight when you fold forward, your spine isn’t the problem — it’s your positioning. Lie on your back with your knees bent and feet flat. Raise your arms overhead to about 120 degrees, palms up.

Your goal is to keep the top of your pelvis in contact with the floor. If it pops up, place a book under your feet to adjust. Inhale silently, then exhale while gently pressing through your heels and reaching your arms farther. This helps flatten your back and calm unnecessary spinal tension.

• Reclaim hamstring mobility with reciprocal inhibition drills — Cupples doesn’t ask you to yank on tight hamstrings. Instead, he teaches your nervous system to stop guarding. Lie on your back with your hips bent 90 degrees. Spread your arms wide at 100 degrees. On each exhale, slowly lower one leg toward the floor without arching your back. Keep alternating legs.

This activates your quads while letting your hamstrings finally let go. Do two to three sets of eight to twelve leg lowers per side, twice daily.

• Finish with the “progressive toe touch” to integrate all gains in real-world movement — Now it’s time to stand up and reconnect your breath to your reach. Place ramps or books under your heels. Wedge a yoga block between your knees. With soft knees — not locked — hinge forward at your hips and let your arms dangle.

Don’t force anything. Inhale and shift weight toward your outer heels, exhale and shift it toward your inner heels. Breathe through five sets of five breaths, twice a day. This trains your body to touch your toes without bracing or flinching.

• Measure small wins to keep motivation high — This plan works in two to four weeks, but you don’t need to wait that long to see change. Mark how far you reach on your pants, your legs or a mirror. Repeat the test every few days. Watching your fingertips drop even half an inch lower builds motivation.

Stretch Smarter, Not Longer — Your Progress Starts in 30 Seconds

Improving flexibility doesn’t require marathon stretch sessions or painful pulls. A practical guide from Nerd Fitness flips that script by introducing four short drills to do in under two minutes total — each just 30 seconds long.3 The goal is to rewire how your body perceives movement, tension and safety. This makes the approach both effective and accessible, especially if you’ve ever felt “too stiff” to make progress or gave up when conventional stretching didn’t work.

This method is designed for people who sit a lot, feel tight in the hamstrings or back, or who want a fast, low-stress way to feel looser and more mobile. Each movement targets a different area of your body. The program also uses gamification: you measure how far down your legs your fingers reach — knees, shins, ankles or floor — to see small improvements and stay motivated.

• Use the standing toe touch to trigger safe lengthening in your entire back body — Stand with your feet hip-width apart and knees soft. Slowly fold forward as far as you comfortably can. Don’t force it. Hold the bottom position for 30 seconds.

• Loosen your spine with the cat/camel stretch — Get on all fours with your hands under shoulders and knees under hips. Inhale as you arch your back and lift your tailbone and chest (camel), then exhale as you round your spine toward the ceiling and tuck your pelvis (cat). Flow slowly between the two, matching each phase to your breath. This mobilizes your spine and creates smoother movement between your hips and shoulders.

• Activate your side body with the star stretch — Stand tall, feet wide, and reach your arms out like a star. Tilt to one side, reaching your hand toward your opposite foot while keeping the other arm straight up. Return to the center, then repeat on the other side. Each side gets 15 seconds. This opens up your obliques, lats, and outer thighs — areas that are often overlooked but important for full-body flexibility.

• Reinforce hip mobility and spine decompression with the “moon the sky” drill — Begin in a low squat with your chest close to your knees and arms hanging. Slowly straighten your legs, keeping your hands under your feet and your spine relaxed. You’ll feel a deep stretch through the back of your legs and hips. Then lower back down. Repeat slowly for 30 seconds. This move trains proper hip hinging, which is essential for bending safely and effectively.

This entire routine takes less than two minutes. Try doing it three times a week or even daily if you prefer. It’s especially useful right after workouts or during transitions, like after sitting for long periods. Short, consistent practice builds a sustainable habit and avoids overwhelming your brain or body.

Touching Your Toes Starts with Fixing How You Move

If you’re frustrated with how stiff your body feels, or you’ve just assumed you’re “not flexible,” it’s time to shift that mindset. The issue isn’t just your muscles being short. It’s usually a lack of coordination between your breath, posture, and nervous system. That means you don’t need hours of stretching or expensive gear.

You need a smarter plan that targets the real source of the problem. Here’s what to do if you’re trying to gain mobility and finally touch your toes — without force, frustration, or flaring up old injuries:

1. Fix your breathing and posture first — Most flexibility problems start with bad posture and shallow breathing. If your ribcage is stuck or your hip flexors are always bracing, no amount of stretching will help. Lie on your stomach with a small pillow under your ribs and hips.

Slowly inhale through your nose while gently pressing your chest off the ground using your elbow and opposite knee. This re-teaches your core to stabilize without tension and sets up the rest of your body to move more freely.

2. Use short bursts of stretching instead of long holds — If you hate stretching, it’s probably because you’re overdoing it or doing it wrong. Try 30-second sessions, like the Nerd Fitness standing toe touch.

Flex the front of your thighs, keep your knees straight, and bend just past where it’s comfortable — then stop. That’s enough. The goal is progress, not punishment. Repeat this three times, once a day. It’s more effective than one long, painful stretch you dread and never repeat.

3. Reprogram your back and hamstrings together — Sitting all day trains your back and hamstrings to stay locked up. You need to teach them to relax. Lie on your back with hips bent and arms reaching up. Exhale slowly as you flatten your spine into the floor and lower one leg at a time. Alternate sides.

This resets tension patterns while keeping your spine protected. If you’re always fighting your body during a stretch, it’s because your brain doesn’t feel safe. This drill fixes that.

4. Track your progress with visual cues — Make flexibility measurable. Use chalk, tape, or your pant leg to mark how far you reach — then recheck after each stretch session. Watching your reach improve just a little bit each time builds momentum. This trick taps into gamification. It’s a reward loop your brain responds to, and it keeps you coming back.

5. Layer stretches around your real life — You don’t have to block off 30 minutes. Just stack stretches into your routine. Do one right after brushing your teeth. Another while your coffee brews. A third after sitting too long. If you’re consistent, you’ll notice more changes from five minutes of smart mobility than an hour of random effort.

This approach respects your time, reduces mental overload and makes success easier to maintain. You don’t need to be born bendy to touch your toes — you just need a system that works with your body, not against it.

FAQs About Improving Flexibility

Q: Can you really improve flexibility in just two minutes a day?
A: Yes. Research-backed routines show that even 30-second daily drills — if done consistently — improve your ability to touch your toes and reduce back pain. The key isn’t how long you stretch but how often and how smartly you move. Techniques that combine breath, posture, and muscle coordination help rewire how your nervous system allows flexibility.

Q: What’s the real cause of limited flexibility?
A: It’s not just tight muscles — it’s your nervous system protecting you. Poor posture, shallow breathing, and movement habits signal your body to limit range of motion. That’s why forcing a stretch doesn’t work. You need to retrain your brain to feel safe allowing movement again. Posture resets and breathing drills are more effective than aggressive stretches.

Q: What kind of stretches or movements work best?
A: Short, targeted drills like seated toe reaches, reciprocal leg lowers, and standing hinging movements are ideal. These techniques don’t just pull on tight spots — they help your body organize movement more efficiently. The goal is to teach your body how to fold, not to force it to. A good example is the “moon the sky” drill that trains safe hip hinging.

Q: How do I stay motivated to keep stretching daily?
A: Make it a game. Use chalk, tape, your pants or props to track how far your hands reach during a toe-touch test. Recheck your reach after each drill to measure progress in real time. This simple visual feedback loop triggers your brain’s reward system, making it easier to stick with the habit and feel encouraged.

Q: When should I fit these exercises into my day?
A: Stack them around daily tasks, like after brushing your teeth, before sitting down to work or while waiting for your coffee to brew. These “micro-practices” reduce mental load and make it easier to be consistent. Just two to five minutes a day is enough to see lasting improvements without needing a gym or yoga class.

You don’t need to collapse after every workout to burn fat or improve your heart health. In fact, pushing yourself too hard often backfires. That’s the power behind Zone 2 training, a method that’s catching attention because it does the exact opposite of what high-intensity trends promise. Instead of gasping for air, you keep a steady pace, and the payoff is real.

The key to sustainable fitness and long-term fat loss isn’t doing more; it’s doing it smarter. The Zone 2 approach targets your aerobic system without overloading your nervous system, allowing you to train longer, recover faster, and build endurance without triggering hormonal backlash. Zone 2 isn’t a trend — it’s a metabolic shift. And once you understand how it works, you’ll stop chasing exhaustion and start making real progress.

Zone 2 Training Burns Fat Without Burning You Out

Fox News explored why Zone 2 training is gaining popularity as a fat-burning method that doesn’t require extreme effort.1 The piece features insights from Carmine Ciliento, fitness manager at Crunch Fitness in New York, who explains that Zone 2 refers to working out at 60% to 70% of your maximum heart rate.

This is the range where your body switches to burning mostly fat for fuel. Specifically, about 65% of your calories come from fat while you’re in this zone. Unlike high-intensity workouts, which rely more on carbohydrates and protein, Zone 2 is about steady, aerobic movement your body sustains for longer without overwhelming your system.

• This approach is especially useful for people just getting started or those who’ve burned out on high-intensity programs — “Zone 2 is especially valuable because it allows you to add cardio volume to your training without overstressing your body,” Ciliento told Fox News.

For beginners, anything more intense is often too much at first. Zone 2 lets you build consistency and endurance gradually. Even better, this level of effort still delivers metabolic rewards without pushing your nervous system or hormones into overdrive.

• You don’t need fancy equipment or lab testing to find your Zone 2 range — Just subtract your age from 220 to get your estimated max heart rate. Then aim for 60% to 70% of that number during exercise. For example, a 50-year-old’s Zone 2 range would be roughly 102 to 119 beats per minute.

Heart rate monitors or wearable fitness devices help track it, but even if you don’t use tech, there’s a simple trick: the “talk test.” If you can speak in short phrases but need to pause to breathe every few words, you’re likely in the right range.

• Zone 2 training is ideal for long-duration activity without the crash afterward — The reason this works so well is because your body is relying on fat instead of sugar to generate energy. This process is more efficient for sustained movement. It’s also gentler on your muscles and joints. Ciliento, who trains for endurance events, uses Zone 2 regularly for recovery, underscoring how effective it is even for high-level athletes.

• What makes Zone 2 so sustainable is that it builds up your aerobic engine quietly but powerfully — You’re not redlining your body or tearing down tissue every time you work out. That means you recover faster and avoid the destructive wear and tear linked with chronic high-intensity exercise. Instead of chasing exhaustion, you’re chasing adaptation — training smarter, not harder.

Zone 2 Helps Strengthen Your Heart and Stabilize Blood Sugar

USA Today explored how Zone 2 cardio supports your body’s ability to deliver oxygen and manage energy more efficiently.2 The feature includes commentary from Dr. Carrie Jaworski, a sports and exercise medicine physician at Intermountain Health in Salt Lake City, who described Zone 2 cardio as light to moderate aerobic exercise that keeps your heart rate steady while still allowing you to talk. This makes it easier to stick with over time and makes it powerful for improving cardiovascular endurance and resilience.

• Zone 2 linked to specific improvements in blood sugar control, fat metabolism, and cardiovascular markers — According to Jaworski, “Zone 2 cardio has been shown to improve lipid levels and insulin sensitivity, as well as decrease the risk of cardiovascular events in those who already have cardiovascular disease.”

This means it doesn’t just help you lose weight; it makes your heart stronger and your cells better at handling sugar. It supports the very processes that protect you from heart attacks, strokes, and diabetes complications.

• Unlike other training zones, this one is designed to keep you in balance while still progressing — Dr. Michael Fredericson from Stanford University explained that the benefits include lower resting heart rate, improved vascular tone, and better blood clotting function. These changes directly support your body’s ability to heal, circulate nutrients, and avoid damage under stress.

• Zone 2 also helps build endurance and power for future workouts — The article makes it clear that staying in this zone helps your body become more efficient at using fat for energy, not just during the workout, but also long after. It builds your “aerobic base,” which makes everything else — like climbing stairs or lifting weights — feel easier over time. According to Fredericson, this low-stress intensity supports long-term training without the burnout that comes from pushing too hard too often.

• You don’t have to be an athlete to use Zone 2 cardio, and it’s one of the easiest ways to begin — Brisk walking, gentle cycling, and swimming all count. Jaworski adds that “Zone 2 training is easier on the body so you can do it more regularly, recover more quickly and are less likely to get burnt out or overtrain.”3 For anyone dealing with stress, fatigue, or previous injury, this method offers a stable entry point into consistent movement and better metabolic health.

• Tracking your heart rate helps, but it’s not required to get the benefits — Jaworski says the talk test is still one of the most practical tools: you should be able to speak a few words at a time without needing to stop completely to catch your breath. This makes it easy for beginners to jump in and stay in the right range without overthinking it.

Zone 2 Builds Mitochondria and Makes You Stronger Over Time

An article in Women’s Health reported how Zone 2 training improves your body’s power output by building the foundation of energy production.4 According to fitness coach Melissa Kendter, this lower-intensity method enhances your performance at higher intensities by improving your aerobic base. As your body becomes more efficient at using oxygen for energy, every movement feels easier and more powerful. This makes Zone 2 training ideal for people who want better strength and stamina without burnout.

• Zone 2 boosts your ability to train harder later by increasing oxygen delivery and energy efficiency — The article highlights that aerobic training increases the number and size of mitochondria, the energy factories inside your cells. It also helps your muscles grow more capillaries, which deliver oxygen-rich blood exactly where it’s needed. These structural changes allow your body to produce more energy with less effort, so even your high-intensity workouts start to feel easier over time.

• It’s less likely to wear you out or cause overtraining, even if you do it daily — Kendter noted that Zone 2 is “just tough enough” — challenging enough to cause change but not so intense that it leaves you depleted. That makes it easier to stick with. You don’t need to recover for days after a session. Instead, show up again the next day and keep building progress steadily. This is what allows people to train consistently, especially those recovering from stress, illness, or years of sedentary habits.

• You don’t need fancy equipment to make this method work for you — Kendter recommended monitoring your breathing as a simple gauge. “You should be able to inhale for three to four counts and exhale for three to four counts,” she said, describing the sweet spot for Zone 2 effort. If you’re talking or breathing too hard, slow it down. This method helps you tune into your body and learn to pace yourself better, boosting confidence and self-awareness in your training.

• Women benefit from a different way of calculating their ideal heart rate range for Zone 2 — Cardiologist Dr. Martha Gulati pointed out that the traditional “220 minus age” formula was based on male data. For women, she suggested a more accurate formula: 206 – (0.88 x age). This personalization makes a real difference, especially for women trying to train smart and get the most out of every session without overdoing it.

Zone 2 Keeps You Below the Burnout Line and Builds Real Stamina

Dr. Eliza Pierko, an orthopedic sports medicine expert at Loyola Medicine, told Verywell Health that Zone 2 training feels deceptively easy — but that’s the point.5 “You feel like you’re not working out,” she said, yet the benefits are significant and lasting. This method has been used successfully by endurance athletes for decades, and now it’s becoming popular among everyday people because it builds stamina without exhaustion.

• This approach allows you to train longer without triggering the pain, inflammation, or fatigue that intense workouts often cause — Benjamin T. Gordon, assistant professor at the University of Florida, told Verywell Health that Zone 2 training keeps you below your lactate threshold.

That’s the point where your body switches to anaerobic (oxygen-deprived) energy and starts accumulating lactic acid, which makes your muscles burn and recovery take longer. By staying below that line, you stay in a state that’s energizing, not depleting.

• You’re tapping into a smarter system that trains your body to become more efficient, not more exhausted — Pierko emphasized that Zone 2 targets slow-twitch muscle fibers. These are the endurance muscles that use fat for fuel and are built for long-term use. Even after hours of steady effort, your body keeps burning fat instead of sugar, supporting sustained energy output without breakdown.

For people looking to maintain consistent energy throughout the day, this matters far more than sprinting into soreness.

• Zone 2 training lowers the risk of injury and overuse because it doesn’t spike inflammation or tear you down — Gordon warned against constantly pushing your body to its limit. “If you go to max effort every day, you’re most likely not gonna adhere to your program and you’re more likely to see injuries,” he said.6 Zone 2 offers a gentler alternative that keeps you consistent. That consistency pays off in cardiovascular health, mental clarity, and metabolic function.

• This method improves blood pressure, heart function, and your body’s ability to regulate energy — Pierko added that Zone 2 helps manage metabolic health and reduces the risk of cardiovascular disease. Your vascular system becomes more responsive, your blood flows better and your muscles adapt to work more efficiently. These benefits are especially helpful for people with blood sugar issues or heart concerns who can’t afford the stress of high-intensity workouts.

Stop Burning Out Your Body to Get Fit

If you’ve been feeling wiped out after your workouts, stuck in a plateau or frustrated with your recovery, the intensity could be backfiring. High-intensity training spikes cortisol, your body’s primary stress hormone, and over time that tears down your muscle, your brain, your bones, and your motivation.

The goal isn’t to do less. It’s to do it smarter. If you’ve been trying to force results with extreme routines, shifting into Zone 2 training is one of the fastest ways to rebuild your energy and restore your progress. Here’s how to get started:

1. Find your Zone 2 heart rate range and stay there for at least 30 minutes — Use the simple formula: 220 minus your age. Then multiply that number by 0.6 and 0.7 to get your target range. For example, if you’re 40, your Zone 2 range is around 108 to 126 beats per minute. If you’re a woman, use the more accurate formula from Gulati: 206 – (0.88 x your age). This zone is where your body uses mostly fat for fuel and doesn’t raise stress hormones, so you get long-term benefits without breakdown.

2. Choose activities that feel natural and don’t leave you gasping — You don’t need fancy equipment. Go for a brisk walk, hike, dance, ride a bike, swim, or even rollerblade. The key is staying at a pace where you can talk in short phrases without gasping. If you’re inhaling for three to four counts and exhaling the same, you’re likely right where you need to be.

3. Engage in moderate exercise often and don’t overthink it — Because Zone 2 is gentle, you can do it multiple days a week without draining your recovery. This makes it one of the easiest ways to train consistently without burning out. Aim for daily movement, split into manageable sessions.

4. Do high-intensity workouts sparingly, if at all — Excessive high-intensity workouts are a fast way to dig yourself into a deeper hole. As Dr. James O’Keefe warns, too much vigorous exercise backfires, accelerating aging and wearing down your body. However, you can’t overdo moderate exercise.

5. Track your progress with how you feel, not just how fast or far you go — As your aerobic base improves, you’ll notice you’re able to go longer without fatigue, your resting heart rate drops and everyday activities get easier. These are the signs that your mitochondria are working better and your metabolism is recovering. Trust the process — slow and steady wins this race.

FAQs About Zone 2 Training

Q: What is Zone 2 training and why does it matter?
A: Zone 2 training is a form of low-to-moderate intensity exercise that keeps your heart rate at 60% to 70% of its maximum. This zone trains your body to burn fat more efficiently, strengthens your cardiovascular system, and builds endurance without spiking stress hormones or causing burnout.

Q: How do I know if I’m exercising in Zone 2?
A: To estimate your target Zone 2 range, subtract your age from 220, then multiply that number by 0.6 and 0.7. For women, use 206 – (0.88 x your age) for a more accurate maximum. If you can speak in short phrases but need to pause for breath, you’re likely in the right zone.

Q: What are the main health benefits of Zone 2 cardio?
A: Zone 2 improves fat metabolism, lowers blood pressure, enhances insulin sensitivity, and increases mitochondrial density, which boosts your body’s ability to create energy. It also reduces your risk of overtraining, joint damage, and hormonal imbalances associated with high-intensity workouts.

Q: How often should I do Zone 2 workouts?
A: Because it’s gentle on your body, Zone 2 training can be done four to six days a week or more. The consistency of these workouts, not the intensity, is what drives long-term benefits.

Q: What types of exercise qualify as Zone 2 training?
A: Activities like brisk walking, hiking, swimming, biking, dancing, or rowing all qualify, as long as you keep your heart rate in the correct range. The key is staying active at a sustainable pace that supports fat burning without exhausting your nervous system.

More than half of women in some populations report premenstrual syndrome (PMS), a condition that disrupts both body and mind on a monthly cycle. The prevalence is as high as 52.2% in certain groups, showing how widespread this issue has become.1 That number reflects more than inconvenience — it points to a recurring biological stress that shapes daily life.

PMS is characterized by a mix of physical and emotional symptoms that appear in the second half of your cycle. These range from fatigue, pain and sleep disruption to irritability, anxiety, and intense mood shifts. For many, the pattern repeats every month, interfering with work, relationships and overall stability. Left unaddressed, this cycle steadily erodes quality of life, especially when symptoms intensify over time.

Standard approaches to PMS often aim to blunt symptoms without addressing what keeps driving them back each month. That gap has pushed researchers to look deeper at what’s actually happening inside your cells during the hormonal shifts that trigger the problem. A controlled trial tested whether drinking hydrogen-rich water daily during the second half of the menstrual cycle could address that deeper mechanism — and the results suggest it can.2

Targeted Daily Hydrogen Intake Reshaped Premenstrual Symptoms

A study published in BMC Women’s Health investigated whether hydrogen-rich water could improve PMS and overall quality of life.3 Researchers designed a randomized, double-blind controlled trial, meaning participants didn’t know whether they were drinking hydrogen water or regular water, and neither did the researchers collecting the data. This type of design strengthens the reliability of the findings because it reduces bias.

The study included women who already struggled with PMS. These participants consumed between 1,500 and 2,000 milliliters (mL) of hydrogen-rich water daily, spaced throughout the day at specific intervals like before meals and before sleep. Compared to the control group drinking plain water, the hydrogen group showed a clear reduction in PMS symptom scores during follow-up assessments.

• Measurable drops in PMS symptoms reflected real relief — The researchers used a detailed scoring system that measures multiple PMS symptoms, including mood changes, fatigue, pain and sleep disruption. Higher scores reflect worse symptoms, so when scores dropped in the hydrogen group, it signaled real relief across several categories.

• Physical and mental well-being improved together — In addition to symptom reduction, participants drinking hydrogen water reported better quality of life, especially in physical health and psychological well-being.

Physical health includes energy levels, pain and daily function, while psychological health reflects mood, stress, and emotional stability. These improvements appeared early, during the first follow-up after consistent use. That tells you the effect isn’t limited to one area — it influences both how your body feels and how your mind responds during the cycle.

• Consistency across multiple cycles drove stronger results — Timing played a key role in the study. Participants started drinking hydrogen water around day 16 of their cycle and continued until the second day of menstruation, repeating this pattern for three cycles. This repeated exposure allowed the effects to build over time. The data showed that benefits persisted across follow-ups, reinforcing that consistency matters more than one-time use.

• Immediate consumption ensured the active compound remained effective — Researchers emphasized that hydrogen-rich water needs to be consumed right after preparation because hydrogen gas dissipates quickly. Participants were instructed to drink it immediately after it reached full saturation. If the hydrogen escapes, the therapeutic effect drops. That gives you a clear rule: timing and freshness determine whether you get the full benefit.

• Hydrogen targets the root stress signals inside your body — PMS is strongly linked to oxidative stress and inflammation, which are internal stress signals that disrupt normal function. Oxidative stress means harmful molecules build up and damage cells, while inflammation amplifies pain and mood instability.

Hydrogen acts as a selective antioxidant, meaning it neutralizes the most damaging molecules without interfering with useful ones your body needs. Most antioxidants work like a firehose — they suppress free radicals broadly, including the ones your immune system uses on purpose. Hydrogen works more like a sniper, going after only the hydroxyl radicals that damage DNA and cell membranes while leaving the signaling molecules your body relies on untouched.

• Cellular energy systems receive direct support — Hydrogen is the smallest molecule, which allows it to pass easily into cells, including the mitochondria — the part of your cells responsible for producing energy. During the luteal phase, rising progesterone increases your metabolic rate, which means your mitochondria are working harder and producing more oxidative waste. That’s why fatigue and brain fog tend to hit hardest in the days before your period.

Once inside, hydrogen helps upregulate your body’s own antioxidant enzymes — particularly glutathione peroxidase and superoxide dismutase — which act like a cleanup crew inside each cell, breaking down the toxic byproducts of energy production before they accumulate and cause damage.

When these systems function better, your cells produce energy more efficiently and generate fewer harmful byproducts. This directly affects fatigue, one of the most common and disruptive PMS symptoms.

How to Use Hydrogen-Rich Water to Restore Cellular Energy and Reduce PMS

PMS symptoms trace back to inflammation and oxidative stress that disrupt how your cells produce energy. When your cells struggle, your brain and body feel it as fatigue, mood swings, and discomfort. Fix that internal imbalance, and everything downstream begins to stabilize. This is where hydrogen becomes useful. It works at the level where your symptoms start — inside your cells. Rather than chasing symptoms, you’re correcting the environment that creates them.

1. Start with hydrogen-rich water to target the root cause — If your fatigue, irritability or brain fog hits hard before your cycle, you’re dealing with cellular stress. Drop one hydrogen tablet into a glass of room-temperature water — about 500 mL works well — and drink it as soon as the tablet fully dissolves and the water turns cloudy white.

That cloudiness is the dissolved hydrogen, and it starts escaping within minutes. Choose tablets that produce 8 to 10 ppm and are tested for purity. This step directly lowers oxidative stress and inflammation, which are the drivers behind your symptoms.

2. Time it correctly so you actually get the benefit — If you let the water sit, the hydrogen escapes and the effect drops. Drink it right away. Don’t sip it slowly over long periods once it’s prepared. Don’t swallow the tablet dry or drink partially dissolved pieces because the reaction produces heat, and taking it dry allows the reaction to occur against your tissue rather than dispersed in water, which can cause irritation or burns.

Fortunately, even if your schedule is busy, it’s easy to build a simple habit — prepare it, drink it, move on. Keep it simple so you stay consistent.

3. Use it daily during the phase when symptoms build — If you track your cycle, begin using hydrogen-rich water in the second half — around day 16 — when symptoms usually start. Continue through the first days of menstruation. This mirrors how it was used in the study and aligns with when inflammation and oxidative stress rise. If your symptoms are unpredictable, use it daily and pay attention to how your body responds.

4. Stay consistent, then cycle it to stay responsive — If you’re dealing with ongoing fatigue or mood swings, daily use builds momentum. Once your energy improves and your symptoms ease, take a short break for a few days or a week. Then restart. This keeps your body responsive instead of adapting and flattening the effect. Think of it like training — the change comes from the pattern, not a single dose.

5. Build a lifestyle that supports the same cellular pathways — If you want stronger and more lasting relief, layer hydrogen with simple habits that reduce inflammation and support energy production. Focus on steady daily movement like walking, regular sleep timing and getting morning sunlight to support your circadian rhythm.

Eat enough carbohydrates from whole foods to fuel your cells — about 250 grams daily — and avoid ultraprocessed foods, including seed oils, that increase oxidative stress and mitochondrial dysfunction. If you feel worse under stress, prioritize downtime and simple routines that keep your nervous system calm. When these pieces work together, you’re not just managing PMS, you’re building a cellular environment that handles hormonal shifts without the monthly crash.

FAQs About Hydrogen-Rich Water for PMS

Q: What is hydrogen-rich water and how does it help with PMS?

A: Hydrogen-rich water is water infused with dissolved hydrogen gas. It acts as a selective antioxidant, neutralizing the most harmful molecules in your cells without disrupting beneficial ones. Since PMS is strongly linked to oxidative stress and inflammation, hydrogen-rich water targets these root causes at the cellular level rather than simply masking symptoms.

Q: What did the study find about hydrogen-rich water and PMS symptoms?

A: A randomized, double-blind controlled trial published in BMC Women’s Health found that women who drank 1,500 to 2,000 mL of hydrogen-rich water daily during the second half of their cycle experienced measurable reductions in PMS symptom scores compared to those drinking plain water.4

Participants also reported improvements in both physical health (energy, pain, daily function) and psychological well-being (mood, stress, emotional stability). Benefits appeared early and persisted across multiple menstrual cycles.

Q: When and how should hydrogen-rich water be consumed for PMS relief?

A: Based on the study, consumption should start around day 16 of your menstrual cycle and continue through the first two days of menstruation, repeating each cycle. It’s important to drink it immediately after preparation because hydrogen gas escapes quickly — don’t sip it slowly or let it sit. Participants spaced their intake throughout the day, such as before meals and before sleep.

Q: Why does consistency matter, and should I cycle on and off?

A: The study showed that repeating the protocol over three consecutive cycles allowed benefits to build over time. For ongoing use, it’s recommended to maintain daily intake until symptoms improve, then take a short break of a few days to a week before restarting. This cycling approach helps keep your body responsive and prevents adaptation that could diminish the effect.

Q: What lifestyle habits enhance the benefits of hydrogen-rich water for PMS?

A: For stronger, more lasting relief, combine hydrogen-rich water with habits that reduce inflammation and support cellular energy production — regular daily movement like walking, consistent sleep timing, morning sunlight exposure, and eating enough whole-food carbohydrates (around 250 grams daily).

Avoiding ultraprocessed foods and seed oils, which increase oxidative stress and mitochondrial dysfunction, and prioritizing stress management also help your body handle hormonal shifts with less disruption.

Colon cancer develops quietly, often without clear warning until it’s advanced. By the time symptoms such as changes in bowel habits, abdominal pain, or unexplained weight loss appear, the disease has already gained ground. This is why prevention matters so much — your daily choices influence whether your colon stays resilient or becomes vulnerable.

Diet is one of the strongest levers you have. Unlike fixed factors such as age or family history, what you eat shapes your gut environment and determines how well your body neutralizes harmful compounds. Certain foods work like medicine, fortifying your defenses against mutations that lead to tumors.

Among the most powerful options are cruciferous vegetables — broccoli, cauliflower, cabbage, and Brussels sprouts. They provide compounds that interact with your cells at a deep level, supporting detoxification, protecting DNA, and strengthening your colon lining.

Including them regularly isn’t complicated or expensive, but it gives you a measurable edge against one of the deadliest cancers worldwide. This foundation sets the stage for the latest research, which offers new insight into how these vegetables deliver their protection and what amount is most effective.

Research Shows Cruciferous Vegetables Cut Colon Cancer Risk

In a paper published in BMC Gastroenterology, researchers combined data from 17 studies involving 639,539 people.1 Out of these, 97,595 had colon cancer. The analysis showed that those who ate more cruciferous vegetables had significantly lower odds of developing colon cancer. The overall reduction in risk was 17%, which is meaningful when you think about preventing a disease that kills over 900,000 people each year.

• The “sweet spot” was surprisingly modest — The strongest protection occurred when people ate about 40 to 60 grams of cruciferous vegetables daily, roughly half a cup of cooked broccoli.

Eating more than 60 grams didn’t appear to provide much additional benefit, which suggests that your body reaches a point of saturation — where the cancer-fighting compounds do their job and more isn’t necessarily better. Importantly, this threshold makes prevention achievable because it doesn’t require extreme dietary changes.

• Specific chemicals in the vegetables drive the effect — Cruciferous vegetables contain glucosinolates, which break down into compounds such as sulforaphane and indole-3-carbinol when the vegetables are chopped or chewed. These compounds support your body in several ways:

◦ Detoxification — They activate enzymes that help your liver process and eliminate carcinogens.
◦ Apoptosis — They trigger programmed death in damaged or pre-cancerous cells.
◦ Cell cycle regulation — They slow down cell division, reducing the chance of runaway growth that leads to tumors.

• The findings held up even under strict testing — Researchers checked for errors or overestimates by running multiple sensitivity analyses, which are tests that remove one study at a time or look for outliers.

The reduction in colon cancer risk held steady regardless of which studies were included or excluded. Even when accounting for possible publication bias — where smaller studies with positive results are more likely to be published — the protective link between cruciferous vegetables and colon cancer risk stayed strong.

• How cruciferous vegetables protect your colon at the cellular level — Sulforaphane tells your body to make more detox enzymes. These enzymes act like janitors, sweeping out harmful substances before they damage your cells. At the same time, sulforaphane also shuts down signals that cancer cells use to stay alive and keep multiplying.

Another compound, indole-3-carbinol, helps control which genes are active, slowing down the growth of abnormal cells. When these natural defenses work together, your colon cells are better protected from harmful changes and shielded against ongoing inflammation.

• Gut health ties into the protective effect — Cruciferous vegetables also help tighten the junctions between cells lining your colon. This is important because when those junctions loosen, toxins and bacteria seep through, fueling inflammation and cancer risk. By strengthening these barriers, the compounds from cruciferous vegetables reduce harmful bacterial activity and give your beneficial gut microbes the upper hand.

That shift in your microbiome supports overall colon health and lowers cancer risk even further. You don’t need massive amounts of these vegetables to experience benefits. Just a moderate serving of cruciferous vegetables most days of the week is enough to activate detoxification pathways, improve gut barrier strength, and reduce your colon cancer risk by double digits. By making this a consistent habit, you build a daily shield inside your body.

Simple Strategies to Strengthen Your Gut and Cut Colon Cancer Risk

If your goal is to lower your risk of colon cancer, you need to start with the root cause: the health of your gut and how your body produces energy. When your gut microbes are balanced and your colon lining is strong, you’re in a far better position to stop abnormal cells before they take hold. On the other hand, when your diet and environment disrupt that balance, your risk climbs fast. These steps give you clear, practical actions that help you rebuild resilience and protection — starting with your plate.

1. Cut out vegetable oils and packaged junk — When you eat restaurant food, fried snacks, or packaged meals, you load your body with linoleic acid (LA) from vegetable oils. This fat poisons your mitochondria — the engines inside your cells — and creates a gut environment that favors harmful bacteria. Swap these foods for fresh, unprocessed choices you cook yourself.

Use stable fats like ghee, tallow, or grass fed butter, and keep LA below 5 grams per day — closer to 2 grams is even better.

2. Fuel your cells with the right carbs — Your gut and mitochondria work best when they get a steady flow of glucose. For most adults, that means 250 grams of healthy carbohydrates daily, with higher amounts if you’re very active. Start simple with white rice and fruit, especially if your gut is unhealthy. This approach gives your cells the energy they need while allowing your gut bacteria to stabilize before you add more complex foods.

3. Introduce more fiber step by step — Fiber feeds the good microbes in your gut, helping them produce butyrate, a short-chain fatty acid that acts like fuel for your colon lining. But too much fiber too soon backfires if your gut is inflamed. Once you’ve done well with fruits and white rice, add in root vegetables, then branch out to cruciferous and other vegetables, beans, legumes, and whole grains.

Cooked and cooled potatoes or rice are especially useful because the resistant starch they form is perfect food for butyrate-producing bacteria. By pacing your fiber intake, you allow your gut to heal and build strength without triggering irritation.

4. Bring in cruciferous vegetables for extra defense — Once your gut tolerates carbs well, make cruciferous vegetables part of your regular diet. Whether you prefer roasted Brussels sprouts, lightly steamed broccoli, or sauerkraut, your choices matter and directly influence whether cancer takes hold in your colon. These foods contain compounds that help your liver clear carcinogens, repair damaged DNA, and strengthen your colon lining.

Aim for 40 to 60 grams a day — roughly half a cup of cooked broccoli — to get the best protection. Rotate different crucifers through your meals to diversify the compounds your gut microbes have to work with. This variety keeps your microbiome healthier and gives your colon more layers of defense.

5. Limit toxins, prioritize daily movement, and restore your microbiome — Environmental toxins — from plastics, pesticides, and synthetic estrogens to constant exposure to electromagnetic fields — undermine your gut health, allowing the wrong microbes to take over. Switch to glass containers, avoid heating food in plastic, and cut down on wireless signals at home where possible.

Movement is another tool that lowers your risk of colon cancer. Research shows that exercising in the morning around 8 a.m. and again in the evening around 6 p.m. reduces colorectal cancer risk by 11%, with this two-peak pattern outperforming other exercise schedules.2

Antibiotics are another disruptor, wiping out beneficial species. Use them only when truly necessary, and then rebuild your microbiome with fermented foods. Once your gut is healthy, supporting beneficial microbes like Akkermansia, which help maintain your gut lining, keeps your colon protected from cancer-triggering toxins.

FAQs About Cruciferous Vegetables and Colon Cancer

Q: How much cruciferous vegetables do I need to eat to lower my colon cancer risk?
A: Research shows the strongest protection comes from eating about 40 to 60 grams a day — roughly half a cup of cooked broccoli. Eating more than this doesn’t seem to add much benefit, but keeping this amount in your daily diet reduces your colon cancer risk by about 17%.

Q: What makes cruciferous vegetables protective against colon cancer?
A: These vegetables contain compounds such as sulforaphane and indole-3-carbinol. Once you chew or chop the vegetables, these compounds activate processes in your body that detoxify carcinogens, trigger cancer cell death, slow down abnormal growth, and strengthen the lining of your colon.

Q: Do cruciferous vegetables also help with gut health?
A: Yes. They help tighten the junctions between cells in your colon lining, reducing the chance of toxins and bacteria leaking through. This shift gives your beneficial microbes the advantage, lowers inflammation, and supports a healthier gut microbiome overall.

Q: Besides eating cruciferous vegetables, what other steps protect against colon cancer?
A: Practical steps include cutting out vegetable oils and packaged junk foods, eating enough healthy carbs, introducing fiber gradually, and reducing exposure to toxins like plastics and pesticides. Daily movement also helps — research shows exercising around 8 a.m. and again at 6 p.m. lowers colorectal cancer risk by 11%.3

Q: Why is prevention so important with colon cancer?
A: Colon cancer often develops silently until it’s advanced, when treatment is harder and survival rates are lower. Prevention gives you control: the foods you eat, your activity level, and your environment directly influence whether harmful changes take hold in your colon.

You need magnesium to survive — literally. This mineral is involved in more than 600 chemical reactions in your body, including those that power your heart, regulate your nerves and help you convert food into usable energy.1 Yet most people aren’t getting anywhere near enough. Even with a clean, whole-food diet, you’re likely still falling short because modern farming has drained the soil of minerals, leaving produce nutritionally weaker than it was just a few decades ago.

In theory, you could get enough magnesium from food. In reality, only about 30% to 40% of what you eat is actually absorbed.2 If you’re relying on spinach, seeds or nuts to top off your intake, you’re facing a double bind: those foods either contain antinutrients that block absorption or come loaded with inflammatory linoleic acid (LA) — a polyunsaturated fat that hijacks your metabolism and builds up in your cells like sludge.

So, even the best food sources of magnesium no longer deliver what your body truly needs. When your magnesium levels drop too low, the signs often start small — tight muscles, leg cramps, restless sleep, low energy.

But left unresolved, this mineral deficiency fuels much bigger issues like blood sugar dysregulation, insulin resistance, high blood pressure, and mitochondrial dysfunction. It’s a silent saboteur with widespread effects on your mood, energy, cardiovascular system and even your brain’s ability to focus and process information.

Different Types of Magnesium Work in Different Ways

Magnesium supplementation is no longer optional for most people — it’s strategic. But not all forms work the same. Some go straight to your muscles or brain. Others just flush out of your system. Knowing which type to use for your symptoms is the first step in reclaiming metabolic health. There are plenty of magnesium supplements on the market, but the following options are — hands down — the top choices, listed in order of overall benefit.

• Magnesium glycinate — calming and gut-friendly — This form is bound to glycine, an amino acid that promotes relaxation. It’s easy on your stomach and ideal if you’re dealing with anxiety, poor sleep, muscle tightness or stress. I favor this version for anyone who tends to be sensitive to supplements or who needs help unwinding and recovering at night.

• Magnesium malate — energizing and supportive for muscles — Malate is found naturally in fruits and plays a role in energy production. If you’re exhausted or experiencing muscle soreness or fibromyalgia-like pain, this is the form I recommend.3 It supports mitochondrial energy output, so it helps turn the lights back on at the cellular level.

• Magnesium taurate — anxiety relief and heart-brain support — This combines magnesium with taurine, an amino acid that calms your nervous system and supports heart rhythm stability. It’s especially useful if you struggle with heart palpitations, stress-related high blood pressure or anxiety that feels tied to your heartbeat. Some evidence also points to brain-protective benefits.

Magnesium Deficiency Is More Common Than Most People Realize

An article published by The Hearty Soul laid out the growing concerns around magnesium deficiency and why so many people are unaware they’re affected.4 Magnesium powers hundreds of enzymatic processes in your body, including how you metabolize glucose, synthesize vitamin D and regulate blood pressure. But due to soil depletion, food processing and poor absorption, even people eating well fall short.

• Processed foods and depleted soils block your ability to get enough — Even the healthiest vegetables today don’t offer the magnesium levels they once did. Modern farming practices strip minerals from the soil, meaning even magnesium-rich foods like leafy greens have significantly lower levels than they did 50 years ago.

On top of that, heavily processed foods dominate most people’s diets. These foods are not only low in magnesium but also high in additives that impair absorption.

• Common foods high in magnesium often come with metabolic downsides — Many people turn to nuts and seeds to boost their magnesium intake. But these foods are extremely high in LA, which accumulates in your tissues and drives inflammation and mitochondrial dysfunction.

If you’re already dealing with fatigue, blood sugar swings or brain fog, adding more LA through nuts and nut-based foods will make those issues worse, even as you try to correct a magnesium deficiency.

• Magnesium deficiency is linked to major health problems — Low magnesium intake contributes to serious metabolic problems. It affects insulin release and blood sugar regulation. When you’re low in magnesium, your pancreas can’t release insulin properly, which leads to higher blood sugar, poor glucose control and ultimately insulin resistance. Over time, this progression leads to metabolic syndrome or Type 2 diabetes.

• It’s also a major issue for heart and vascular health — One of magnesium’s most important roles is keeping your blood vessels flexible and relaxed. Magnesium helps your blood vessels release nitric oxide, a compound that naturally relaxes vessel walls and lowers blood pressure.5 Without enough magnesium, your blood vessels constrict more easily, your blood pressure creeps up and your risk of cardiovascular problems increases.

The Right Magnesium Restores Your Energy, Sleep and Focus Faster Than You Think

If you’re dealing with fatigue, poor sleep, brain fog or blood sugar issues, there’s a good chance magnesium deficiency is at the root. But just adding random supplements won’t solve the problem.

You need a strategy that corrects the imbalance at its core, starting with how you absorb, metabolize and select the right type of magnesium for your body. Most people are operating with a cellular energy deficit, and magnesium is one of the fastest ways to reverse it — if you do it right. Here’s how I recommend you get started:

1. Stop relying on food alone to meet your magnesium needs — When it comes to magnesium, most people are deficient. Even if you eat whole, organic foods, you’re still not getting enough magnesium.

Soil depletion has drained vegetables of their mineral content, and nuts and seeds — while high in magnesium — are loaded with LA, which blocks energy production and worsens inflammation. I generally recommend getting nutrients from food, but magnesium is a rare exception. It’s nearly impossible to hit the recommended 400 milligrams (mg) per day through food alone.

2. Identify your ideal dose using magnesium citrate — This form is inexpensive and highly bioavailable, but it has a laxative effect. That’s actually useful: it helps you find your dose. Start small, then slowly increase the dose until you get loose stools.

Once that happens, dial back slightly. That’s your ideal dose. After that, switch to a more tolerable form — like glycinate or malate — at the same dose. This one trick helps you absorb what you need without overdoing it or guessing blindly.

3. Use the right type of magnesium for your situation — I favor magnesium glycinate and magnesium malate because they’re well-absorbed and easy on your digestive system. If your biggest issue is tension, irritability, trouble sleeping, or anxiety, glycinate is calming and gentle.

If you’re dragging through the day with low energy, sore muscles, or brain fog, magnesium malate supports energy production by feeding your mitochondria. I’ve seen great results using these two forms depending on what your body needs most.

4. Don’t waste time on topical-only magnesium if you’re depleted — I favor magnesium glycinate and malate for a reason: they work systemically. Magnesium oils, lotions and bath flakes made from magnesium chloride feel relaxing but do very little to raise your internal levels.

If you’re dealing with sleep problems, low focus or metabolic issues, you need an internal fix — not just a temporary surface effect. Use topical forms only as a complement, not a replacement.

5. Keep your supplement routine clean and targeted — Look for magnesium supplements with no artificial colors, fillers or unnecessary binders. You don’t need fancy blends with 10 ingredients. You need the exact form your body needs, at the dose that works for you.

Magnesium isn’t just another supplement. It’s a metabolic switch that turns your system back on. Once you correct the deficiency, everything else starts to work better: your energy stabilizes, your mind clears, and you sleep deeper without effort.

FAQs About Magnesium

Q: What are the most effective forms of magnesium for daily use?

A: The forms I most often recommend are magnesium glycinate and magnesium malate. Glycinate is ideal if you’re struggling with anxiety, stress, or sleep issues because it promotes calm and is easy on your stomach. Malate supports energy production and is especially helpful if you deal with fatigue, brain fog, or muscle soreness. Both forms are highly absorbable and generally well tolerated.

Q: How do I know how much magnesium I need to take?

A: Start with magnesium citrate to find your personal threshold. It’s well absorbed but has a laxative effect, which works well as a dosing tool. Slowly increase your dose until your stools become loose, then back off slightly. That’s your ideal dose. Once you know your number, switch to a gentler form like glycinate or malate to maintain that intake without side effects.

Q: What symptoms could mean I’m low in magnesium?

A: Common signs include tight muscles, leg cramps, poor sleep, low energy, anxiety and blood sugar swings. If left unaddressed, magnesium deficiency contributes to more serious problems like insulin resistance, high blood pressure, metabolic dysfunction, and cognitive decline. This is one deficiency that affects nearly every system in your body.

Q: Why isn’t food alone enough to meet my magnesium needs?

A: Modern farming has depleted the soil of minerals, including magnesium. Even organic produce contains far less than it did 50 years ago. Add to that the low absorption rate of magnesium (only about 30% of dietary intake is usable) and the inflammatory fats in common food sources like seeds and nuts, and it’s clear why supplementation is often necessary.

Q: What’s the difference between the seven forms of magnesium?

A: Each form targets a different need. Glycinate and malate are the two forms I recommend most often because they’re well absorbed, easy on your digestive system and effective for restoring balance without unwanted side effects.

• Glycinate — Best for sleep, stress, and muscle relaxation

• Malate — Supports energy, focus, and muscle recovery

• Citrate — Boosts absorption and relieves constipation

• Oxide — Poor absorption but helps with indigestion

• Chloride — Good for topical use, less effective internally

• Taurate — Calms nerves and supports heart rhythm

If you feel hungry again soon after eating, crave snacks between meals, or experience an energy crash an hour or two after food, your appetite system has lost its timing. You may eat enough calories yet still feel unsatisfied. Blood sugar rises and falls too quickly. Hunger signals arrive early and stay loud. This pattern does not reflect weak discipline or poor food choices. It signals a breakdown in how your gut communicates fullness and fuel status to the rest of your body.

When it comes to weight loss, there’s a hidden system in your body that works quietly behind the scenes — not in your muscles or fat cells, but deep in your gut lining. It’s a hormone system powered by butyrate, a short-chain fatty acid (SCFA) that your gut bacteria make when you eat fiber. Butyrate fuels L-cells — specialized sensors in your gut lining that release a hormone known as GLP-1, short for glucagon-like peptide-1 — in response to fermentation, signaling that you’ve eaten enough.

GLP-1 plays a central role in appetite control, blood sugar balance, and fat storage.1,2 It’s released within minutes after you eat and acts like a broadcast signal, telling multiple organs that fuel has arrived and intake can slow.

You may have heard of GLP-1 in the context of medications like Ozempic and Wegovy, which mimic this natural hormone. But when your body makes its own GLP-1 the way it’s supposed to, you already have a built-in weight regulation system — no injections, no prescriptions needed.

To turn that system back on, you need to restore butyrate. Everything else — stable energy, fewer cravings, easier fat loss — flows from there. This is the central premise of my new book, “Weight Loss Cure; Melt Fat Naturally With Your Own GLP-1.”

Butyrate Fuels the Cells That Control Hunger

Butyrate is made in your colon when beneficial bacteria ferment certain types of fiber. It’s best known as the main energy source for colonocytes — the cells lining your large intestine — but its role doesn’t stop there. Butyrate also fuels L-cells, which sit along your intestinal wall and act as your body’s metabolic messengers.

When butyrate reaches them, it triggers the release of GLP-1. GLP-1 is the hormone that tells your brain you’ve eaten enough, slows the movement of food through your stomach, stabilizes blood sugar, and reduces the desire to snack between meals. In short, butyrate powers the hormone that helps regulate your appetite.3,4

When this system works as designed, appetite regulates itself — and fat loss follows without conscious restriction. You eat less, not because you’re forcing yourself to, but because you’re full. You stop craving sugar. Your energy feels steady. Your metabolism stops pushing calories into fat cells and starts using them for energy again. But when your gut doesn’t make enough butyrate, that entire system is blunted.

Beyond serving as fuel, butyrate helps maintain a low-oxygen environment in the colon. When colon cells receive adequate energy from butyrate, they consume oxygen efficiently, keeping the gut environment anaerobic. This low-oxygen state is essential because most butyrate-producing bacteria cannot survive when oxygen levels rise.

Seed Oils Undermine Butyrate

A primary driver of insufficient butyrate production is the modern diet. Seed oils high in linoleic acid (LA), processed grains, and a lack of fermentable fiber — all of these starve your gut bacteria of the raw materials they need to make butyrate. On top of that, environmental toxins, antibiotics, and chronic stress damage the gut lining and wipe out the very microbes that produce it.

LA disrupts butyrate production through several converging effects. It increases oxidative stress and low-grade inflammation in the gut lining, which raises local oxygen levels in the colon. That shift favors oxygen-tolerant microbes while suppressing the strictly anaerobic bacteria responsible for producing butyrate. Over time, this altered environment reduces fermentation efficiency, weakens the gut barrier, and further amplifies inflammation — creating a cycle that steadily drives butyrate levels down.

When that happens, your L-cells lose their fuel, and GLP-1 release drops. As a result, your stomach empties too quickly, your blood sugar swings out of control, and your brain doesn’t get the signal to stop eating. Hunger kicks in faster. Cravings increase. Fat storage ramps up. Your metabolism hasn’t failed — it’s just running without the fuel it needs.

How GLP-1 Regulates Hunger and Metabolism

GLP-1 is one of the most important hormones in your digestive and metabolic system. It’s secreted after meals and acts on multiple organs to keep energy balance in check:

• In your brain, it reduces appetite and increases feelings of fullness
• In your stomach, it slows emptying so you stay full longer
• In your pancreas, it increases insulin release and reduces glucagon, helping manage blood sugar
• In your fat tissue, it improves insulin sensitivity and supports fat burning. By improving insulin sensitivity and slowing nutrient delivery, GLP-1 shifts energy away from fat storage and toward immediate use, increasing the likelihood that calories get burned rather than stored

GLP-1 is your body’s natural appetite regulator, and it’s designed to activate every time you eat. GLP-1 receptor agonist drugs like semaglutide (Ozempic, Wegovy) copy these effects, but they come with a long list of potential side effects, as they override your body’s natural rhythm.

GLP-1 medications replace a missing signal by forcing the receptor to stay active. Restoring butyrate does something fundamentally different. It amplifies your body’s own signaling by supplying the fuel L-cells need to release GLP-1 in the right amounts, at the right time, in response to food. One approach overrides physiology. The other rebuilds it.

You don’t need to hijack the system. You just need to restore the environment that lets it work — by feeding the cells that make GLP-1 what they need: butyrate. Once you restore GLP-1 signaling through adequate butyrate, the effects do not stop with appetite control. The same fuel that helps L-cells regulate hunger also supports gut integrity, immune balance, and brain signaling. These downstream benefits reflect the wider role butyrate plays in maintaining metabolic stability throughout your body.

Butyrate also stimulates the release of peptide YY (PYY), another satiety hormone produced by L-cells. PYY works alongside GLP-1 to slow digestion and reinforce fullness after meals, helping hunger stay suppressed between eating periods.

Butyrate’s Broader Benefits

Rebuilding your GLP-1 signaling through butyrate doesn’t just affect appetite. It also strengthens the systems that support stable metabolism long term. Importantly, it:

• Reinforces gut barrier integrity — Butyrate provides up to 70% of the energy colon cells need. With enough fuel, these cells form a tight barrier that keeps irritants and pathogens out of your bloodstream. When that barrier breaks down — often due to low butyrate — inflammation ramps up, immune reactivity increases, and blood sugar control suffers.5

• Reduces systemic inflammation — Butyrate suppresses nuclear factor kappa B (NF-κB), a master inflammatory switch that, when overactive, worsens insulin resistance and metabolic dysfunction.
Butyrate also inhibits the NLRP3 inflammasome, another key driver of inflammation that responds to cellular stress and injury,6 while boosting the production of interleukin-10 (IL-10), a powerful anti-inflammatory cytokine that tells immune cells to stand down.7 Moreover, studies show that butyrate reduces circulating C-reactive protein (CRP), a marker of systemic inflammation that’s elevated in a wide range of chronic diseases.8

• Supports brain health — Butyrate supports the gut-brain axis by reducing neuroinflammation and preserving the physical integrity of the blood-brain barrier. This barrier is a specialized structure that keeps harmful substances in the bloodstream from reaching the brain.
It also acts on microglia, the brain’s resident immune cells, helping to suppress their overactivation. Chronic microglial activation has been implicated in anxiety, depression, and neurodegenerative diseases like Parkinson’s and Alzheimer’s.
Additionally, butyrate influences the production of neurotransmitters such as serotonin and gamma-aminobutyric acid (GABA), which help regulate mood, stress, and sleep. Animal studies suggest that increasing butyrate levels may improve symptoms of anxiety and support recovery from chronic stress and inflammation that affect the central nervous system.9

• Regulates immune activity — Your immune system needs to strike a delicate balance — stay alert to real threats without overreacting to harmless stimuli. Butyrate plays an important role in maintaining this balance. When produced in sufficient amounts, it influences the behavior of immune cells, encouraging the growth of regulatory T cells (Tregs) that promote tolerance and suppress overactive responses.10,11

• Lowers colorectal cancer risk — In the colon, butyrate promotes apoptosis (cell self-destruction) in precancerous and cancerous cells, helping reduce the risk of colorectal cancer. It also supports healthy cell turnover and differentiation, both of which are necessary to prevent abnormal growths in the intestinal lining.12

These benefits do not appear through supplementation alone or isolated food choices. They emerge when your gut environment supports steady butyrate production day after day. That requires a deliberate sequence: calm the gut first, rebuild tolerance next, and only then expand fermentation. The steps below follow that biological order.

How to Support Your Gut’s GLP-1 System

Think of this process as restoring terrain before planting seeds rather than forcing growth in damaged soil. Your gut microbiome plays a key role in how your body processes carbohydrates and regulates blood sugar levels. By taking targeted steps to enhance your gut health, you can restore and support the bacteria in your gut that produce butyrate and other SCFAs. Just keep in mind that your microbiome is as unique as your fingerprint.

What works for one person may differ for another, so patience and personalization are key. That said, here are a few foundational basics that will benefit most people:

1. Start with gut terrain repair — If you’re bloated, constipated, or sensitive to high-fiber foods, you need to calm inflammation before you feed the microbiome. That means:

• Avoiding fermentable fibers at first. When your gut is out of balance, high-fiber foods — even the “healthy” ones — can work against you. Foods like beans, lentils, oats and raw greens ferment quickly when the wrong bacteria are in control. This creates gas, pressure and inflammation, and worsens gut lining damage.
• Eliminating seed oils (such as soybean, corn, canola, sunflower). The linoleic acid in seed oils damages the exact gut microbes you’re trying to support. If your diet includes fried foods, processed snacks, or sauces made with soybean, corn, sunflower, or canola oil, you’re suffocating your good gut bacteria.
Replace those fats with ghee, grass fed butter or tallow — fats your body actually knows how to use. The goal is to shift your internal terrain so your gut bacteria thrive again.
• Using simple carbs like white rice and ripe fruit to stabilize energy without feeding bad bacteria.

2. Reintroduce fiber in phases — Move on to fiber reintroduction only after you meet this criterion: You tolerate three consecutive days of white rice or ripe fruit with no bloating, abdominal pain, excess gas, or bowel urgency. At that point, introduce one resistant starch source at a time, starting with 1/2 cup cooked-and-cooled white potato once daily.

Once you can consume 1/2 cup cooked-and-cooled potato daily for seven consecutive days with no increase in gas, bloating, stool looseness, or abdominal discomfort, advance to inulin-rich foods such as garlic, onions and leeks. These fibers bypass digestion in your small intestine and head straight to your colon, where they fuel beneficial bacteria that make butyrate.
Keep in mind that progress is oftentimes slow and non-linear. That is completely normal, and not a cause for concern. Just keep going; eventually your gut will normalize.

3. Support with optional tools — Once your gut begins to stabilize, these targeted tools can help accelerate butyrate production and improve results:

• Akkermansia postbiotics (Phase 1) — Postbiotics are non-living bacterial components that still deliver biological signals. Pasteurized forms of Akkermansia muciniphila contain Amuc_1100, a protein shown to tighten the gut barrier and reduce inflammation. Look for postbiotic formulas with enteric coating or microencapsulation to ensure they survive stomach acid and reach the colon intact.
Without that protection, less than 5% of Amuc_1100 reaches your colon. You could try megadosing to compensate, but that’s expensive and inefficient. Prioritize coated formats to support your gut barrier more effectively.
• Live Akkermansia (Phase 2) — Begin Phase 2 probiotics only after all of the following occur:

◦Bloating remains minimal or absent
◦Stool form stays consistent for at least 7 days
◦Fiber tolerance expands without symptom return

In this stage, introduce live probiotic Akkermansia alongside gentle prebiotics — like small amounts of resistant starch — to support the growth of butyrate-producing strains and reestablish a healthy, oxygen-sensitive microbial environment.

• Fermented foods — Traditionally fermented foods can boost microbial diversity and support butyrate-producing strains. Go slowly. Start with small amounts to test tolerance, especially if your gut is sensitive. Examples are given in the next section.

• Gut testing — A stool analysis can reveal which bacteria are present, whether your gut is inflamed, and how well you’re producing short-chain fatty acids like butyrate. This can guide food choices and supplementation more precisely.

• Resistant starch — Found naturally in cooked-and-cooled potatoes, green bananas, and legumes — or as supplemental powders — resistant starch bypasses digestion in the small intestine and becomes prime fuel for butyrate-producing bacteria in the colon.

4. Adjust your environment — Your gut doesn’t just respond to what you eat. It’s tuned into your entire lifestyle. These daily habits help create the internal rhythm your microbiome needs to thrive:

• Sleep — Align your sleep-wake cycle with natural light exposure. Aim for 7 to 9 hours of high-quality sleep and get morning sun to anchor your circadian rhythm. This helps regulate gut motility and microbial repair.
Why it matters: Consistent, circadian-aligned sleep regulates gut motility, microbial repair, and GLP-1 timing, allowing butyrate-producing bacteria to recover and function efficiently.
• Stress — Chronic stress alters your microbiome and shuts down butyrate production. Use daily tools like breathwork, walking outdoors, and nervous system regulation practices to calm your hypothalamic-pituitary-adrenal (HPA) axis and support microbial balance.

Why it matters: Chronic stress suppresses vagal tone and alters gut signaling, which reduces fermentation efficiency and directly lowers butyrate production.

• Fasting window — Stop eating at least three hours before bed. This gives your migrating motor complex (MMC) — your gut’s internal clean-up crew — time to sweep out bacteria and food debris overnight, reducing fermentation and inflammation.

Why it matters: Overnight fasting activates the migrating motor complex, clearing excess bacteria and debris so fermentation stays balanced rather than inflammatory.

Foods That Enhance Butyrate Production

The most effective way to increase butyrate is to provide the raw materials your gut bacteria need to make it. Key producers like Faecalibacterium prausnitzii, Roseburia, and Eubacterium rely on specific dietary inputs to thrive. However, not all fibers ferment the same way, and not every gut can handle them equally. Once you’re ready to reintroduce fiber, as explained in the previous section, you can start adding in:

• Prebiotic-rich foods — Prebiotics are nondigestible food components that selectively feed beneficial gut bacteria, such as:13

Garlic
Onions
Asparagus
Chicory root
Jerusalem artichokes
Green bananas
Turnip greens

Broccoli
Carrots
Cooked oats
Seaweed and microalgae
Legumes (soaked or pressure-cooked peas, lentils, and beans)

• Fermented foods — Fermented foods don’t produce butyrate themselves, but they help shape the terrain that makes it possible. By delivering live organisms and metabolic byproducts, they strengthen your gut lining and help crowd out problematic strains. These include:

◦Sauerkraut
◦Kimchi
◦Kefir
◦Plain, full-fat yogurt
◦Fermented pickles

Introduce these into your diet slowly and in small amounts. Their microbial density makes them highly active, so monitor how you respond to each one individually.

• Direct food sources of butyrate — Full-fat dairy products naturally contain small amounts of butyric acid, which supports colon cell energy and barrier strength. Good sources include:

◦Grass fed butter
◦Ghee
◦Aged cheeses like Parmesan
◦Whole milk, cream, or yogurt

Signs Your Gut Is Making More Butyrate

The following improvements reflect rising butyrate levels and gut healing in real time:

• Bowel movements become regular and well-formed — A sign of improved colonic motility and mucosal integrity.
• Fiber tolerance improves — Less bloating, gas, or discomfort after meals rich in fermentable fiber.
• Hunger fades between meals — As GLP-1 and PYY production increases, satiety naturally extends.
• Mood feels more stable and stress less overwhelming — Butyrate supports BDNF and modulates the HPA axis.
• You lose fat without trying to eat less — Improved metabolic signaling leads to spontaneous caloric reduction.
• Reduced post-meal blood sugar spikes — A measurable effect tied to improved insulin sensitivity and GLP-1 response.
• Lower fasting insulin and triglycerides (if tested) — Both improve with SCFA restoration and microbiome balance.
• Fewer cravings for processed carbs and snacks — Satiety hormones rise while inflammation-driven hunger decreases.
• Less urgency or discomfort with bowel movements — Improved stool consistency reflects stronger gut barrier and reduced inflammation.
• Improved breath or reduction in sulfur/gas odors — Indicates better fermentation profile in the colon (fewer sulfur-releasing or proteolytic bacteria).

Track Your Progress: How to Know It’s Working

To track your recovery, keep a simple symptom journal for the first four to six weeks. Each day, jot down quick notes on these four markers:

• Bloating — None, mild, moderate, or severe
• Energy — Steady, sluggish, or crashing
• Mood — Calm, tense, irritable, anxious
• Bowel quality — Bristol stool scale (types 3 to 4 are ideal), frequency, urgency, discomfort

Even just a few words per day can help you see patterns clearly, especially when deciding when to add new foods or supplements. Once you begin reintroducing fermentable fiber, use a 1 to 10 scale each week to rate how well you’re tolerating it. If you’re not at a 7 or above, pause before advancing to the next phase.

• 1 = severe gas, bloating, or pain
• 5 = some symptoms, improving
• 10 = no symptoms, excellent digestion

If you want objective data, run these labs at baseline and again around week 8. These markers, while optional, offer biochemical confirmation that your butyrate–GLP-1 axis is restoring normal metabolic function.

• Fasting insulin — Falling levels suggest better GLP-1 signaling
• Triglycerides — Often improve as inflammation and insulin resistance drop
• Post-meal glucose — Ideally stays under 120 mg/dL at the 1-hour mark

Timeline: What to Expect as Your Gut Rebuilds

Your gut already knows how to help you lose weight — by producing butyrate, which fuels the cells that make GLP-1. This is how human metabolism was designed to function. Restore that system, and your cravings shrink, your blood sugar stabilizes, your inflammation calms down, and your body starts releasing excess weight naturally.

These shifts are clear signs that your body’s metabolic software is running the way it was meant to. Your gut doesn’t need to be perfect to start producing butyrate. But there’s a rhythm to recovery, and markers to know it’s working.

Not everyone experiences fat loss on the same timeline. In some people, metabolic improvements — such as steadier energy, improved blood sugar control, and reduced inflammation — appear weeks before any change on the scale. These early shifts signal that GLP-1 signaling and microbial balance are restoring, even if weight changes lag behind.

When Do You Need to Supplement?

Even with the best diet and lifestyle, there are situations where your gut may not produce enough butyrate on its own. Short-term supplementation can help when:

• Your gut has been dysbiotic for years
• You’re recovering from antibiotics or illness
• You’re managing chronic inflammation or stress
• You’re unable to tolerate fermentable foods yet

However, it’s important to note that most butyrate supplements release too early in the digestive tract, dissolving in the small intestine before reaching the colon. To get its benefits, you need to choose a formula designed for targeted delivery throughout the entire colon. To optimize benefits, look for butyrate supplements that offer:

• Colon-targeted release
• Delayed dissolution
• Multi-region delivery

Final Thoughts

Weight loss is not about fighting your body — it’s about fueling the system it already built. Your gut holds the switch for hunger, fullness, blood sugar, and energy balance. Butyrate flips that switch by nourishing the cells that make GLP-1. This isn’t a shortcut. It’s not a hack. It’s the return of a system that worked for thousands of years before processed food, seed oils, and gut-disrupting toxins broke it.
Feed the system, fuel the cells, and let your metabolism do what it was designed to do. Weight change follows metabolic repair, not the other way around.

You can start putting these strategies into practice right now with my new book, “Weight Loss Cure; Melt Fat Naturally With Your Own GLP-1,” which provides a step-by-step plan to rebuild butyrate production, restore natural GLP-1 signaling, and correct the root drivers of weight gain.

Frequently Asked Questions (FAQs)

Q: What is butyrate, and why does it matter for weight?
A: Butyrate is a short-chain fatty acid produced when your gut bacteria ferment fiber. It powers the cells in your colon — including the L-cells that produce GLP-1, the hormone that helps regulate hunger, fullness, and fat storage. Without butyrate, GLP-1 can’t do its job.

Q: How does GLP-1 help you lose weight?
A: GLP-1 slows down digestion, reduces appetite, and improves how your body uses insulin. It tells your brain you’re full and curbs cravings. Restoring your natural GLP-1 signaling helps you eat less without trying — and that leads to fat loss over time.

Q: What are the best foods to support butyrate production?
A: Start with gentle carbs like cooked and cooled rice, peeled sweet potatoes, and ripe fruit. As your gut improves, add prebiotic-rich foods like garlic, asparagus, green bananas, and soaked legumes. Fermented foods and full-fat dairy also help.

Q: Why do seed oils interfere with butyrate production?
A: Seed oils are high in linoleic acid (LA), which disrupts gut microbes and promotes inflammation. This damages your colon lining and encourages the growth of microbes that don’t produce butyrate — or worse, microbes that cause bloating, gas, and metabolic dysfunction.

Q: Can I take a supplement instead of changing my diet?
A: Supplements can help temporarily, especially if your gut is very compromised. But to restore long-term butyrate production, you need to rebuild your microbial terrain. Diet and lifestyle are what make the changes stick.

Picture this: you step out of the shower, glance down and see a tangle of hair circling the drain — more than usual. You wonder, “What’s happening to my hair?” While stress or family genes could be culprits, there’s another common reason you might not have thought of: vitamin deficiencies. Your hair acts like a window to your overall health, dropping hints about what’s going on inside your body.

When it thins or falls out more than normal, it’s often a signal that you’re low on some key nutrients. Nutrients like vitamins D, B12 and A, and iron, keep your hair looking full and healthy. If you don’t get enough, your locks could suffer as a result.

Understanding Your Hair’s Growth Cycle

Hair growth follows a structured cycle with three phases: the growth phase (anagen), the transition phase (catagen), and the resting phase (telogen). This process ensures continuous renewal, much like a plant that sprouts, matures, and eventually sheds to allow new growth. Vitamins are indispensable to this cycle, acting as nutrients that sustain hair health.

For example, vitamin D supports healthy hair follicles, while B vitamins contribute to keratin production — the protein that forms your hair’s structure. Insufficient levels of these nutrients disrupt the cycle, causing hair to enter the resting phase prematurely and resulting in increased shedding or thinning. In short, vitamins are the foundation for robust hair growth; without them, the cycle falters.

What Are the Benefits of Vitamin D for Your Hair?

Widely recognized for supporting bone health, vitamin D also plays a key role in hair vitality. It promotes the development of cells that develop into hair follicles, the microscopic structures responsible for hair growth. Vitamin D levels are often low in people with hair loss.1 A deficiency impairs follicle production, leading to thinning hair. Consider vitamin D as the catalyst that initiates healthy hair renewal.

• Identifying a vitamin D deficiency — Signs like excessive hair loss, along with fatigue or muscle pain, may point to low vitamin D levels. The best way to know if you’re in an optimal or deficient state is to get your vitamin D level tested. I recommend doing this twice a year. Regular monitoring is key to keeping your vitamin D level in a healthy range, ideally between 60 to 80 ng/mL (150 to 200 nmol/L).
• Strategies to boost vitamin D — The best way to boost your vitamin D level is with regular sun exposure. However, I need to caution you about sun exposure during peak hours if you consume dietary seed oils. These oils, which are rampant in processed and fast food, are packed with linoleic acid (LA). When LA accumulated in your skin interacts with the sun’s ultraviolet (UV) rays, it triggers inflammation and DNA damage.

It’s best to avoid direct sunlight during peak hours (10 a.m. to 4 p.m.) until you’ve cut back on seed oils for six months. This gives your body time to clear some of the accumulated LA. If sun exposure isn’t possible, vitamin D3 supplementation is often necessary. Remember to have your vitamin D levels tested and, based on your test results, adjust your sun exposure or your supplement dose accordingly to maintain a vitamin D level between 60 to 80 ng/mL.

How Do B Vitamins Help Your Hair Stay Strong?

Biotin (B7) helps make keratin, the protein your hair’s built from. Not enough, and your hair might get brittle or thin.2 Think of biotin as the builder stacking strong bricks for your hair. Vitamin B12 keeps your blood cells healthy, carrying oxygen to your hair roots. When these vitamins are low, hair becomes weak, grows slowly or break easily.

• Signs of deficiency — Thinning hair with symptoms like fatigue or pale skin often signal a B vitamin shortage. Hair loss and red, scaly rashes (especially on your face) are common signs you may need more biotin.
• Increasing B Vitamin Intake — To increase vitamin B12, incorporating B12-rich foods, such as grass fed meat and dairy, into your diet. Vegetarians and vegans, who are particularly at risk for vitamin B12 deficiency due to dietary restrictions, should consider supplements. Oral or intramuscular vitamin B12 supplements help restore adequate levels, depending on the severity of the deficiency.
Oral supplementation is generally effective for mild to moderate deficiency, with dosages ranging from 1,000 to 2,000 micrograms daily. Intramuscular injections, typically administered monthly, may be more suitable for patients with severe deficiency or those with malabsorption issues. Pastured egg yolk is one of the best sources of biotin. Since biotin is water-soluble, your body will not store it. Hence, your intake needs to remain consistent.

Why Does Iron Matter for Your Hair Growth?

Iron is essential for hair health, helping red blood cells carry oxygen to hair follicles.3 Without enough iron, follicles can’t get the oxygen they need, slowing growth and causing shedding. While too little iron contributes to thinning hair, having either too much or too little iron has serious repercussions. The fact is, iron deficiency is commonly checked for, but iron overload is a far more common problem, yet is often overlooked or ignored.

• Detecting low iron — Hair loss along with fatigue, memory problems, or pale skin could mean an iron deficiency.4 A straightforward blood test, known as a serum ferritin test, provides valuable insights into your iron status. You want your ferritin level below 100 ng/mL; the ideal range is 20 to 40 ng/mL. Below 20 ng/mL is an indicator that you are iron deficient, while a level above 100 ng/mL indicates inflammation, high iron or both.

• Boosting iron levels — Eat iron-rich foods like grass fed red meat and pair them with vitamin C from citrus fruits to improve absorption.5 Before considering supplements, be sure to get a serum ferritin blood test, as too much iron is harmful.

How Does Vitamin A Help or Hurt Your Hair?

Vitamin A keeps your scalp healthy by controlling sebum production, the natural oil that moisturizes hair.6 Too little dries out hair, while too much contributes to thinning and scalp issues. Vitamin A is like a dial that needs to be set just right for optimal hair growth.

• Recognizing vitamin A imbalance — Dry, brittle hair is often a sign you need more vitamin A, but thinning or scalp irritation could signal excess.7

• How to boost vitamin A levels — To optimize your vitamin A status, focus on consuming a variety of vitamin A-rich foods. Good sources include liver, egg yolks, butter from grass fed cows, and orange and yellow vegetables like sweet potatoes and carrots. These foods provide either preformed vitamin A or provitamin A carotenoids that your body can convert to active vitamin A.

While supplementation can be beneficial if you’re deficient, it’s important not to exceed recommended intake levels, due to negative effects from excessive supplementation. If you’re concerned about your vitamin A status, consider having your levels tested before starting any supplementation regimen.

Supporting Hair Health Through Nutrition

Your hair often reflects your inner health, with thinning or shedding hinting at deficiencies in vitamins D, B12, or A, and possibly iron. Each plays a unique role in hair growth, strength, and scalp health. The good news? Fixing these gaps is simple. A diet rich in nutrients, based on a variety of whole foods, gives your hair what it needs.

If hair loss continues, however, see a holistic doctor, as a blood test is useful for spotting nutrient deficiencies, leading to targeted treatments like diet changes or supplements to get your hair growth and overall health back on track.

Frequently Asked Questions About Vitamins and Hair Loss

Q: Which vitamins are most important for hair growth?
A: Vitamin D, vitamin B12, biotin, iron, and vitamin A are key nutrients for hair health, supporting follicles, hair strength, and scalp health.

Q: How should I get these vitamins?
A: Sunlight is the best source of vitamin D. Vitamin B12-rich foods include grass fed meat and dairy. Pastured egg yolk is one of the best sources of biotin, while iron-rich foods include grass fed red meat. Good sources of vitamin A include liver, egg yolks, butter from grass fed cows, and orange and yellow vegetables like sweet potatoes and carrots.

Q: How can I identify a vitamin deficiency?
A: Watch for thinning hair, fatigue, or pale skin. Ask for a blood test from your doctor to confirm any nutrient deficiencies.

Q: Can supplements quickly fix hair loss?
A: While certain supplements support hair health, diet comes first. Be sure to prioritize dietary changes, with a focus on fresh, whole foods, and use supplements only when needed.

Q: What causes excessive hair shedding?
A: Some shedding is normal, but nutrient deficiencies often worsen it. Hair shedding is also triggered by hormonal changes (pregnancy, menopause, thyroid disorders), stress, certain medications, sudden weight loss, seasonal changes, and underlying health conditions like autoimmune disorders.

Magnesium sits at the center of cellular survival. It’s the second most abundant mineral inside your cells, required for energy production, nerve signaling, muscle contraction, immune defense, and stable heart rhythm. Without adequate magnesium, your cells struggle to make adenosine triphosphate (ATP) — your body’s energy currency — your nervous system misfires, and calcium floods places it doesn’t belong.

You obtain magnesium from whole foods like fruits, vegetables, dairy, and animal proteins, yet biological need rises sharply during stress, illness, and injury — and it’s difficult to get enough magnesium from food alone. Hypomagnesemia — meaning abnormally low magnesium levels — is characterized by fatigue, muscle spasms, abnormal heart rhythms, confusion, immune instability, and, in severe cases, seizures and cardiovascular failure.

These symptoms rarely appear alone. They overlap with infection, respiratory failure, and electrolyte chaos, which is why magnesium deficiency often goes unnoticed. Most people assume a standard blood test settles the question. It does not. Roughly 99% of your magnesium lives inside bone, muscle, and soft tissue, not in your bloodstream.

That means normal lab values frequently coexist with deep cellular depletion. This disconnect drives treatment delays that raise the risk of sepsis, prolonged ventilation, clotting dysfunction, and death during critical illness. When your body is facing severe illness, magnesium behaves less like a nutrient and more like a control signal.

When it falls out of balance, multiple systems drift at once. Once you understand how central magnesium is to cellular control systems, it becomes clear why researchers focus on its behavior during critical illness and what those findings reveal about survival itself.

Severe Illness Rapidly Destabilizes Magnesium at the Cellular Level

A paper published in Veterinary Clinics of North America: Small Animal Practice analyzed magnesium regulation in critically ill patients and animals, with a focus on why deficiency and excess both raise mortality risk.1 Rather than treating magnesium as a minor electrolyte, the researchers evaluated it as a central regulator of cellular stability, enzyme activity, and electrical signaling during severe stress.

• In critically ill intensive care unit (ICU) populations, magnesium disruption is the norm, not the exception — The paper reports that low magnesium levels appear in up to 65% of human ICU patients and more than half of critically ill dogs, compared to just 6% in general hospital populations. That gap shows magnesium loss tracks directly with illness severity, not diet quality or age alone.

• Low magnesium strongly aligns with worse survival markers in critical care — The paper links hypomagnesemia to higher sepsis rates, longer ICU stays, increased need for mechanical ventilation, and higher death rates. From a practical standpoint, this means magnesium status acts like a risk multiplier. When levels fall, other treatments lose effectiveness, and recovery slows.

The researchers highlight that kidney strain, medications, and metabolic disturbances drive steep magnesium losses. These factors stack together, meaning the sicker someone becomes, the faster magnesium depletion accelerates.

• Blood tests fail to reflect real magnesium status, creating a false sense of security — Since 99% of magnesium lives inside bone, muscle, and soft tissue, serum tests measure only the remaining 1%, which often stays normal even when cells are depleted. This explains why symptoms often persist despite “normal labs.”

• Magnesium acts as a calcium gatekeeper inside cells — One key mechanism described is magnesium’s role as a natural calcium antagonist. In simple terms, magnesium blocks excess calcium from flooding cells.

Without this control, nerves misfire, muscles spasm, blood vessels constrict, and heart rhythm destabilizes. The review also details magnesium’s role as a required cofactor for ATP-generating enzymes. When magnesium drops, energy production falters, leaving cells unable to maintain electrical balance or repair damage.

By regulating calcium flow, enzyme activity, immune signaling, and electrical stability, magnesium determines whether cells adapt or fail under stress. That framing helps explain why its loss predicts deterioration long before outward collapse appears.

• Too much magnesium is also dangerous, especially with kidney impairment — While less common, hypermagnesemia increases mortality when kidney filtration declines. Excess levels depress nerve reflexes, slow heart rate, lower blood pressure, and impair breathing.

Magnesium Acts as a Frontline Stabilizer in Pediatric Critical Care

A comprehensive review published in Cureus analyzed magnesium’s role in pediatric critical care, focusing on clinical impact, therapeutic use, dosing strategies, and safety monitoring rather than basic physiology.2 The goal was to determine how magnesium status affects real-world outcomes in hospitalized children facing life-threatening conditions.

The review addressed children admitted to intensive care with conditions such as sepsis, severe asthma, respiratory failure, cardiac arrhythmias, and neurological emergencies. Across these settings, disrupted magnesium balance consistently aligned with worse clinical trajectories, while correction aligned with measurable improvement.

• Correction of magnesium deficiency led to faster physiologic stabilization — Magnesium supplementation improved markers such as heart rhythm control, respiratory muscle function, and seizure frequency in acute care settings. In sepsis cases, magnesium administration aligned with improved lactate clearance, meaning cells regained the ability to produce energy more efficiently under stress.

Magnesium also helped steady dangerous heart rhythm problems, including sudden chaotic beats and very fast, irregular heart rhythms, reduced bronchospasm during severe asthma attacks, and lowered seizure burden in neurological crises. For parents and caregivers, this translates to fewer emergencies spiraling into multi-organ failure.

• The greatest gains occurred in high-risk pediatric subgroups — Children with sepsis, kidney stress, high diuretic exposure, or respiratory failure showed the clearest improvements after magnesium replacement. These groups experience rapid electrolyte loss, making magnesium restoration a decisive factor in recovery speed.

• Magnesium compared favorably against other supportive interventions — The review notes that magnesium often corrected arrhythmias and neuromuscular instability when potassium or calcium replacement alone failed. This comparison underscores magnesium’s coordinating role rather than acting as a secondary nutrient. The researchers explain that magnesium helps cells keep making energy when oxygen is low and inflammation is high.

Magnesium supplementation also moderated inflammatory signaling during sepsis and respiratory distress, reducing immune overreaction while preserving defense against infection. This balance matters because excessive inflammation often causes more damage than the original infection.

• Another magnesium benefit involves neuromuscular stabilization — By regulating neurotransmitter release at nerve endings, magnesium reduced excessive muscle contraction and airway tightening in asthma and respiratory failure. For a child struggling to breathe, this directly affects survival odds.

• Safety hinged on monitoring rather than avoidance — The review emphasized that adverse effects arose primarily in children with impaired kidney filtration receiving unchecked dosing. With proper monitoring, magnesium therapy remained both effective and controllable in pediatric ICU settings.

Magnesium status functions as a modifiable variable during critical illness rather than an unavoidable consequence. When tracked, adjusted, and individualized, it becomes a stabilizing tool that supports faster recovery and reduces escalation risk.

Why I Recommend Magnesium Supplements Over Food Alone

What researchers see in ICUs reflects a more extreme version of what happens under everyday stress. The same forces that drain magnesium during critical illness — medication use, inflammation, metabolic strain, and impaired absorption — operate more quietly in daily life. Magnesium loss rarely starts with poor choices.

It begins with depleted soil, chronic stress, medication use, and digestive strain that block absorption long before symptoms show up. If you feel foggy, wired at night, sore for no clear reason, or slower to recover, your cells are signaling a power shortfall. Food still matters, but when magnesium demand rises and absorption falls, supplements become the most reliable way to restore balance rather than a shortcut.

1. Start by matching magnesium support to how your body responds, not numbers on paper — If you deal with low mood, shallow sleep, muscle tension, headaches, or mental fatigue, treat those as real-world signals that your nervous system is underpowered. Tracking what you eat rarely tells you anything useful about magnesium status because absorption varies widely and most magnesium doesn’t show up on standard labs.

Instead, pay attention to how your body responds as you adjust magnesium support. Calmer sleep, steadier energy, fewer muscle tight spots, and improved focus are the feedback that tells you you’re moving in the right direction.

2. Stop relying on nuts and seeds even if labels say they’re “high magnesium” — I don’t recommend nuts or seeds because their linoleic acid (LA) content disrupts mitochondria and increases inflammatory stress. When metabolic or gut function is already strained, that stress increases cellular magnesium demand and worsens utilization rather than replenishing it.

Removing nuts and other LA-rich foods, like vegetable oils, reduces a hidden driver of magnesium strain instead of relying on a source that creates competing stress.

3. Identify what drains magnesium from your body every day — If you use acid reflux drugs, water pills, or alcohol, or deal with kidney stress, magnesium loss accelerates. The most effective next step is simply recognizing these drains. Each one you reduce or remove protects your magnesium reserve and steadies energy production without adding a single supplement.

4. Find your personal magnesium threshold before choosing a long-term form — I recommend taking magnesium citrate first because it reveals your limit. You increase the dose gradually until stools loosen, then back off slightly. That point marks your ideal intake. Once you know it, you can switch to better-tolerated forms without guessing on your ideal dose. This step builds confidence because your body gives clear feedback.

5. Choose the magnesium form that targets your biggest complaint — If stress or sleep problems dominate, magnesium glycinate fits best. If fatigue or muscle soreness leads, magnesium malate supports energy recovery. Treat this like matching the right tool to the job so you see results faster.

Magnesium works best when paired with daily movement, consistent sleep, and lower stress. It’s part of a healthy foundation you strengthen day by day, not a crutch you lean on. When your cells regain magnesium balance, everything built on top of that foundation becomes easier to support.

FAQs About Magnesium During Severe Illness

Q: Why does magnesium matter so much during severe illness?
A: Magnesium helps keep your cells stable when your body is under extreme stress. During severe illness, injury, or infection, magnesium demand rises sharply while losses accelerate. When levels fall, multiple systems lose coordination at once, including heart rhythm, immune control, nerve signaling, and energy production, which raises the risk of complications.

Q: Why do standard blood tests often miss magnesium problems?
A: Most of your magnesium is stored inside cells, bone, and soft tissue, not in your bloodstream. A normal blood test only reflects a small fraction of total magnesium and often looks fine even when cells are depleted. This disconnect explains why symptoms persist despite “normal labs.”

Q: Who is at the highest risk for magnesium depletion?
A: Risk rises if you experience chronic stress, inflammation, digestive strain, kidney stress, or use medications like acid reflux drugs or diuretics. In hospitals, the sickest patients lose magnesium the fastest, but the same mechanisms operate more quietly in everyday life.

Q: Why isn’t food alone enough to restore magnesium balance?
A: Modern soil depletion, impaired absorption, and higher metabolic demand make it difficult to meet magnesium needs through food alone. Even a nutrient-dense diet often fails to keep pace when stress or illness increases cellular demand, which is why targeted supplementation becomes necessary.

Q: How do you know if magnesium support is helping you?
A: The most reliable feedback comes from how you feel. Deeper sleep, steadier energy, fewer muscle tight spots, calmer nerves, and clearer thinking signal improved magnesium balance. Your body’s response matters more than tracking food intake or chasing lab numbers.

DMSO is a remarkable naturally occurring substance that (provided it’s used correctly1) safely and rapidly improves a variety of conditions medicine struggles with — particularly chronic pain. For example, thousands of studies show DMSO treats a wide range of:

• Injuries such as sprains, concussions, burns, surgical incisions, and spinal cord injuries (discussed here).

• Strokes, paralysis, many neurological disorders (e.g., Down syndrome and dementia), and numerous circulatory disorders (e.g., Raynaud’s, varicose veins or hemorrhoids), which were discussed here.

• Chronic pain (e.g., from a bad disc, bursitis, arthritis, or complex regional pain syndrome), which was discussed here.

• Many autoimmune, protein, and contractile disorders such as scleroderma, amyloidosis, and interstitial cystitis (discussed here).

• Head conditions, such as tinnitus, vision loss, dental problems, and sinusitis (discussed here).

• Internal organ diseases such as pancreatitis, infertility, liver cirrhosis, and endometriosis (discussed here).

• A wide range of skin conditions such as burns, varicose veins, acne, hair loss, ulcers, skin cancer, and many autoimmune dermatologic diseases (discussed here).

Many challenging infections such as shingles, herpes, chronic ear or dental infections, and osteomyelitis (discussed here). In turn, since I started this series, it struck a chord, and I have received over 2000 reports of remarkable responses to DMSO, and many readers have had for a variety of “incurable conditions.”

This begs an obvious question — if a substance capable of doing all of that exists, why does almost no one know about it? Simply put, like many other promising therapies, it fell victim to a pernicious campaign by the FDA, which kept it away from America despite decades of scientific research, congressional protest, and thousands of people pleading for the FDA to reconsider its actions. Consider for example, this 60 Minutes program about DMSO that aired on March 23, 1980:

In the 1960s a miraculous treatment for chronic pain, traumatic injury, strokes and spinal cord paralysis was discovered that spread across America like wildfire—until the FDA buried it.Here, 60 Minutes exposed the FDA using the same playbook they used throughout COVID-19.

DMSO and Cancer

Since there is a longstanding tendency for any “unproven cancer therapy” to be targeted by the medical industry, once the pioneers of DMSO realized early research showed DMSO was also remarkable for cancer, a decision was made not to focus on that research as a justifiable fear existed that doing so would bury DMSO (particularly since DMSO was already in a precarious position with the FDA). As a result, there is very little knowledge of how DMSO changes the cancer paradigm. For example:

• There are hundreds of studies showing DMSO routinely transforms cancerous cells into noncancerous ones.

• DMSO directly inhibits the growth of a wide range of cancers.

• DMSO allows the immune system to regain the ability to target cancerous cells that have evaded the immune system,2 which not only eliminates cancer but also can create permanent immunity to cancers.

• DMSO makes many conventional cancer therapies much more potent, both making a cure more likely and a far lower (and thus less toxic dose) dose needed to achieve it.

• Many natural therapies become dramatically more potent when combined with DMSO (e.g., one DMSO combination ranks amongst the most effective cancer treatments I’ve ever encountered).

Furthermore, in addition to directly eliminating cancers, DMSO’s remarkable ability to heal and protect the body can also make challenging cancers far more manageable. In my eyes, the suppression of DMSO’s uses as an adjunctive cancer therapy represents the most egregious aspect of this story as in those instances, it’s not even competing with cancer treatments — it’s just reducing the suffering they cause (which if anything should be good for the cancer business).

DMSO and Radiation Therapy

Many of DMSO’s remarkable properties result from it effectively protecting cells from a variety of otherwise lethal stressors (e.g., burns,3 freezing,4 blood loss,5 asphyxiation,6 UV light,7 and soundwaves8) and it significantly accelerates healing from injuries (e.g., sprains9 or burns10).

In addition to protecting cells from other sources of injury, as early as 1961,11 DMSO was also recognized to protect cells and tissues from radiation exposure, and by 1967,12 to protect the skin. This is because DMSO prevents radiation from:

• Breaking apart chromosomes,13 DNA, RNA, proteins,14 and the mitochondria.15

• Creating damaging oxygen species16 and free radicals.17

• Triggering an immune response (e.g., by reducing IL-1, IL-6, TNF-α, and TGF-β18), chronic inflammation, fibrosis, and adhesions.

• Putting cells into senescence19 (a state of permanent growth arrest).

• Causing normal cells in the vicinity of the affected ones to die as well (e.g., when only 1% of cells are exposed to radiation, approximately 30% of non-irradiated cells will exhibit similar toxic effects too20), a fascinating phenomenon I believe is mediated through mitogenic radiation emissions.

Since cancer radiation therapy frequently creates a variety of acute and chronic injuries such as burns, fibrosis, and internal tissue adhesions (all of which DMSO treats), DMSO is incredibly valuable for cancer patients undergoing radiation therapy — particularly since DMSO not only prevents radiation damage but also rapidly heals the injuries radiation creates.21,22

Most importantly, DMSO’s protective effects are specific to normal cells. In contrast, many studies show it increases cancer cells’ susceptibility to radiation.23

Note: I believe our focus on radiation therapy ultimately resulted from mining magnate James Douglas devising a way to produce cheap radium and then giving a large donation (along with subsequent donations) to America’s premier cancer institute to create a program for developing cancer radiation therapy that then spread across the world.24,25

Radiation Exposure Studies

Studies have repeatedly shown that DMSO protects cells26 (particularly when given prophylactically27) from being damaged by (often otherwise fatal28) radiation. For example, DMSO was shown to protect skin cells from dying after exposure to gamma radiation29 and make hamster cells four times as resistant to radiation.30

These same protective properties have also been found in plants31,32,33 and many animals (e.g., mice,34,35,36,37,38,39,40,41,42,43 rats,44,45,46,47,48,49 rabbits,50 newts,51 and fruit flies52).

In animals, DMSO was repeatedly found to protect them from otherwise lethal radiation exposures53,54,55 and protect their skin,56 tails,57 oral mucosa,58 eyes,59 kidneys,60 intestines61 (which are particularly vulnerable to radiation damage), and testicles62 from radiation damage, along with protecting sperm from mutations63 and to accelerate tissue cellular regeneration following an injury.64

Finally, DMSO was shown to prevent the psychological trauma and behavioral changes rats typically experienced from radiation injuries (presumably by preventing radiation from causing injury65).

DMSO also has a remarkable ability to protect and heal the skin from injury,66 and since 1966,67 numerous Russian, German, and Japanese studies have demonstrated DMSO’s impressive ability to protect human skin (along with its collagen and mucopolysaccharides) from radiation.68,69,70,71,72,73,74,75,76,77,78,79,80

For example, DMSO has been shown to treat radiation fibrosis,81,82 radiation dermatitis,83 radiation injuries84 and other local radiation complications.85

Note: While DMSO can treat radiation injuries, it is the most effective if given immediately beforehand to prevent radiation injuries.86

DMSO has also been shown to protect tissues besides the skin. For example:

• In 80 patients who’d developed late local radiation complications (induration, ulcers) from the treatment of breast or genital cancer (or a noncancerous disease) DMSO resulted in both a high efficacy of treatment with no side effects.87

• In 22 patients with cervical cancer topical found DMSO prior to internal gamma-ray radiation therapy prevented the normally expected radiation burns and other toxic reactions to the treatment (e.g., in the bladder and rectum) seen in 59 controls and that DMSO did not protect cancerous tissue.88

• In 807 patients with cervical uterine cancer, putting 10% DMSO into the bladders an hour before receiving weekly internal irradiation therapy, dropped the radiation damage to the rectum from 19.0% to 9.5% and to the bladder from 8.8% to 7.1% (both of which dropped to 1.7% if metronidazole was also used).89

• In another study, DMSO had a 50% success rate in treating patients which chronic radiation cystitis (e.g., from prostate cancer therapy).90 Likewise, a 1979 study also used DMSO to treat radiation cystitis.91

• In 22 breast and cervical cancer patients, DMSO protected them against radiation dermatitis (e.g., erosion, blistering, itching, and pain) while also enhancing cancer sensitivity to radiation (as the DMSO treated areas showed skin reddening and exfoliation earlier) and accelerating the regrowth of normal tissues.

Additionally, when DMSO was only applied to one side, the non-applied side did worse, the hyperpigmentation that follows radiation therapy was greater in DMSO treated patients, and that only one of the 22 patients had to stop DMSO (due to having a skin eruption which may have been linked to DMSO).92

• This author detailed a case of a patient with lung cancer that was treated with three months of radiation therapy but severely damaged her lungs (making her require oxygen and leaving her unsure if she’d survive) — but after topical and oral DMSO, she had a rapid recovery.

Likewise, he also shared a case of another woman with lung cancer who was expected to have significant lung complications from the treatment (as she required a borderline lethal dose), but took topical DMSO prior to each treatment and instead had no complications and was fully healthy three years later.93

It is thus quite remarkable that all of this remains unknown. To quote the author of a 2022 study94 which found DMSO prevented testicular damage (and loss of hormonal function or fertility) following radiation therapy:

“Currently, there is no approved agent for the prevention or treatment of radiation-induced testicular injury … In summary, our findings demonstrate the radioprotective efficacy of DMSO on the male reproductive system, which warrants further studies for future application in the preservation of male fertility during conventional radiotherapy and nuclear accidents.”

Similarly, in addition to the higher doses experienced from radiation therapy, diagnostic radiation, specifically CT scans (which expose the body to much higher radiation doses than X-rays) also pose a cancer risk — particularly since the dose of radiation with CT scans can have over a 10-fold variation.95

In turn, a CT scan was found to make you 17% to 24% more likely to develop cancer,96 with the risk increasing97 the younger you were at the time of the scan and is much higher for certain types of cancers.98,99,100,101,102 A 2009 study estimated 29,000 cancers were caused by the CT scans performed in America in 2007.103

As such, I avoid CT scans, which I do not feel are essential (particularly since a detailed physical exam frequently provides more actionable information). It is my sincere hope at some point in the future, DMSO will be given in conjunction with CT scans (but unfortunately their use keeps going up, and they are viewed as a highly lucrative growth market104).

Tumor Surgery

Since DMSO rapidly accelerates the healing of tissue and addresses the neurological components of pain, many studies have found that DMSO greatly facilitates surgical recovery (e.g., by accelerating healing, improving the strength of the final scar, reducing surgical site pain and eliminating fibrosis, enlarged scars, or tissue adhesions).

As cancers are frequently treated with surgical removal, DMSO can also greatly aid the recovery from these surgeries (e.g., in dogs that required a unilateral mastectomy, giving IV DMSO 15 minutes before the surgery’s conclusion significantly reduced post-surgical inflammation105).

Likewise, studies such as a 1992 trial106 of 198 patients with Stage III colon cancer, and a 1992 trial107 of 228 patients with stomach cancer found DMSO significantly reduced the chance that those cancers would relapse.

Extravasation Injuries

Since the medical field has been extremely reluctant to consider any alternative cancer treatment that could threaten its bottom line (regardless of how much data is behind it), DMSO has essentially not been utilized in the treatment of cancer. However, there is one exception to this rule, as DMSO is able to address a challenging issue encountered with chemotherapy without threatening the existing market.

Since many chemotherapy drugs are quite toxic, they have to be administered in a tightly controlled manner. Unfortunately, in many cases however, the drug gets through the injected vein (extravasates) and leaks into the surrounding tissue.

Note: Since extravasations are often not reported, estimates widely vary on how common they are (e.g., according to one study, in 0.1% to 6% of adults who receive chemotherapy108 while another made a compelling case extravasations occur in 39% of patients109).

Due to how toxic some of the chemotherapy drugs are (particularly the anthracyclines), when that leakage occurs and the drugs concentrate in one area, it can often cause significant damage to the surrounding tissues and lead to ulceration or necrosis (tissue death).

Since the existing treatments don’t always give satisfactory results and DMSO is extremely effective at healing a wide range of tissue injuries, it eventually got used as a treatment for these injuries and quickly caught on. For example:

• A 1981 rat study of doxorubicin extravasations showed that daily topical applications of 1 ml 90% DMSO with 10% α-tocopherol significantly reduced ulcer diameter.110

• A 1982111 and 1986112 study tested numerous agents on ulcers created by applying intradermal doxorubicin to pigs and rats and found DMSO was the only agent that prevented or healed those ulcers.

• A 1984,113 1987,114 and 1994115 pig study along with a 2007 rat study116 also found DMSO treated or prevented extravasation injuries.

Likewise, in humans:

• A 1983117 case report, another 1983 case report,118 a 1989 series119 of 4 patients, a 1991 series120 of two patients, a 1994 series of two patients121 and a 2001 case report122 reported that DMSO prevented extravasations from causing ulcerations of tissue death or healed existing injuries (e.g., with “striking” improvement).

• A 1988 study gave topical DMSO for anthracycline extravasations every 6 hours for 14 days to 20 patients, which prevented all of them from developing ulcerations. In the 14 who were evaluated at 3 months, there was no sign of residual damage in six patients, while a pigmented indurated area remained in ten.123

• A 1995 study gave topical DMSO (for 8 hours a day over 7 days) alongside 3 days of intermittent cooling to every patient who experienced an extravasation over a 3.5 year period (which was either from doxorubicin, epirubicin, mitomycin, mitoxantrone, cisplatin, carboplatin, ifosfamide, or fluorouracil).

Of those 144 patients, 127 could be evaluated, of whom only 1 ultimately developed an ulceration from the extravasation, and none experienced side effects from DMSO (beyond temporary skin irritation and a breath odor).124

• A 1996 study of ten successive patients who experienced extravasation from chemotherapy were given DMSO and alpha-tocopherol, all of whom avoided ulceration or tissue death.125

• A 2004 study of 147 patients with extravasations of anthracyclines (which typically leads to 28% developing ulcerations), found 99% DMSO caused only 1% to 2% of them to develop ulcers.126

• A 2007 study explored applying DMSO and α-tocopherol as a gel rather than a liquid solution to treat extravasation injuries (which appeared to hold promise).127

Chemotherapy Injuries

In addition to addressing extravasation injuries, DMSO has also:

• Been found to prevent doxorubicin cardiac toxicity.128

• Successfully treated palmar-plantar erythrodysesthesia resulting from doxorubicin treatment.129

• Prevent the skin death that is often associated with injecting doxorubicin into the eyelid (which is done to treat eye spasms).130

• Protect against birth defects caused by hydroxyurea.131

• Reduce the carcinogenicity of chlorambucil (which often causes a secondary tumor to form after the initial treatment).132

• Decrease the lung injuries (e.g., pulmonary fibrosis) and weight loss caused by bleomycin.133,134,135

DMSO has also been found to improve many other symptoms associated with chemotherapy (e.g., DMSO is frequently used to treat hair loss from a variety of causes, including chemotherapy) since it saves normal cells on the verge of dying following chemotherapy.

Note: We find Ultraviolet Blood Irradiation following chemotherapy to be the most effective option for protecting a patient’s healthy cells from dying.

Cancer Pain

Cancer (and its treatments) are often accompanied by many other debilitating symptoms, including pain — which is so severe that opioids, rather than being restricted, are routinely used to treat it (e.g., fentanyl is often used to treat advanced cancer pain — but in 10% to 20% of patients the pain is severe enough that even the strongest opioids can’t address it136).

Since DMSO has a rather unique mechanism of treating pain, it is often able to treat a wide range of challenging pain conditions nothing else works on (e.g., I’ve now had hundreds of readers share life-changing pain improvements from topical DMSO nothing else they’d tried had ever worked on). As such, many over the years have found it provided incredible relief for metastatic cancer pain.

One of the most well-known examples was Otis Bowen MD (a popular second-term Indiana governor), who “illegally” used topical DMSO to treat his wife’s pain from terminal multiple myeloma and then publicly denounced the FDA’s absurd embargo on it at the AMA’s 1981 national meeting.137

Remarkably, a few years later, Bowen became Reagan’s Secretary of Health and Human Services. Still, even then, with this highly ethical doctor at the helm of the HSS, DMSO was unable to overcome the FDA’s prohibition of it — which helps to highlight the incredible challenge RFK Jr. is now facing (but gradually surmounting). Likewise, a few studies have shown that DMSO can treat cancer pain:

• A 1967 study included two older patients with cancer pain, one of whom had an excellent response to DMSO and one who had a good response.138

• A 1967 study found that of 7 patients with metastatic cancer pain, DMSO gave 2 full and 2 partial remission.139

• A 2011 trial gave DMSO and sodium bicarbonate to 26 patients with advanced cancers who were experiencing significant pain (even with all the available treatment options).140 This greatly improved their pain, their quality of life (e.g., chemotherapy symptoms), their blood counts, and their organ function:

Note: A 2010 paper further discusses DMSO’s ability to treat intractable cancer pain.141 It highlights that this may be due to DMSO’s ability to address membrane hyper-excitability (e.g., through suppressing NMDA and AMPA induced ion fluxes — which are linked to central pain sensitization142,143 and may explain why DMSO also effectively treats complex regional pain syndrome144).

Conclusion

DMSO’s ability to heal the body and restore its normal function transformed the practice of medicine, and had the FDA not buried DMSO sixty years ago; our medical science would be leaps beyond where it is now. In this article, I’ve tried to show how DMSO helps to address one of the most challenging decisions many will face in their lifetimes — is it worth tolerating the immense damage conventional cancer therapies will cause in return for them saving one’s life?

As such, it’s unconscionable that DMSO was never incorporated as an adjunctive therapy for conventional cancer care, particularly in the case of radiation therapy, since a vast body of literature shows simply applying it shortly beforehand can prevent most of the complications from radiation therapy and significantly increase its ability to treat cancer.

However, while it has been immensely painful to watch the unnecessary suffering created by our outdated and pathological medical practices, for the first time in my life, I am simultaneously immensely hopeful. That is because Make America Healthy Again has created the window to spark the momentum to begin revisiting many of our long accepted medical practices and have our society ask if there is actually a better (or more affordable) way to do things.

Author’s Note: This is an abridged version of a longer article that reviews how DMSO also directly treats cancer (e.g., by turning cancer cells back into normal cells or mobilizing the immune system to eliminate them) and how it greatly enhances the effectiveness of both conventional and natural cancer therapies (along with guidance for using DMSO to treat cancer and many other related conditions). That article can be read here.

The role of sun exposure for your well-being is a topic that’s close to my heart, and for more than two decades it’s one of the top recommendations that I stand firm on. One of the benefits, of course, is that it allows you to optimize your vitamin D levels — however, the benefits far surpass that, as it actually awakens the essence of your biology.

In this podcast, I go into the details on why getting optimal sun exposure is one of the cornerstones of health, particularly the role it plays in optimizing your cellular energy. I encourage you to listen to it in its entirety as it will help you understand this groundbreaking information that will help you reach optimal health.

Just Like Plants, You Cannot Thrive Without Sunlight

There’s no question that the sun powers every form of life on the planet. Plants, for example, cannot survive without sunlight, as they need it for photosynthesis. When the sun’s rays shine on a plant, the electrons in the chloroplasts, a sac-like organelle that contains chlorophyll molecules, convert the solar energy to structural energy in the form of glucose. This then fuels the biological processes in the plant.

You, on the other hand, mostly rely on the foods you eat as an energy source. Take note that I said “mostly,” because did you know that you also have the capacity to use sunlight to produce cellular energy?

In low light, a plant can survive for a time. However, it will not thrive — its leaves will not become green and lush, it will not produce beautiful flowers, and its growth will be stunted. The same can happen to humans. You cannot reach your full health potential unless you’re getting regular sun exposure.

There is one caveat to this, however. If you’ve been eating a diet high in vegetable oils or seed oils, you need to approach sun exposure with caution, as these oils increase your risk of sunburn. That’s why I recommend avoiding high-intensity sun exposure unless you’ve been off these oils for at least four to six months. I’ll explain why further below.

Sunlight Is the Unrecognized Nutrient You Cannot Live Without

Just like plants, you need sunlight to thrive, as there’s a biological mechanism in your body that transforms sunlight into cellular energy. I’m actually in the process of doing some experiments and have set up a mitochondrial research lab to study this theory more closely.

But basically, here’s how it works — your body, when exposed to the sun, collects electrons from solar energy that are used for mitochondrial energy production. This is why failing to get enough sun exposure can have severe consequences for your health.

Your body primarily gets its energy from the foods you eat. When you digest food in your intestine, it is ultimately metabolized to tiny molecules called acetyl-Coenzyme A.

As acetyl-Coenzyme A enters the mitochondria and goes through the Krebs cycle, it is converted into electrons, which are then carried by NADH and FADH2 into the electron transport chain (ETC). This final stage of cellular respiration is where the electrons are transformed by your body into adenosine triphosphate (ATP) — the fuel on which your body runs. To help you understand, here’s an illustration of how cellular energy is created.

Occasional itching or peeling between your toes is often the first sign of a fungal infection starting to take hold. Athlete’s foot, or tinea pedis, is one of the most widespread fungal infections worldwide, thriving anywhere warmth and moisture linger — especially inside shoes, gym floors, and shared showers. Fungi multiply where your skin stays moist, whether that’s inside sweaty socks, between your toes after a shower, or in shoes that never fully dry.

Once established, the infection often lingers for weeks or even returns after treatment if the root cause isn’t addressed. Left unchecked, it doesn’t stop at surface irritation. The same fungi that attack your skin spreads to toenails, creating thick, brittle, discolored nails that are far harder to eliminate.

For anyone with diabetes, poor circulation, or compromised immunity, even small cracks in your skin open the door to more serious bacterial infections. Knowing how to interrupt that cycle — and restore your skin’s natural defenses — is the foundation for lasting relief. Recent findings reveal how targeted natural treatments and simple daily habits eliminate athlete’s foot and help you prevent it from coming back.

Natural Remedies Offer Real Relief for Athlete’s Foot Without Harsh Drugs

Athlete’s foot develops when fungi like Trichophyton overgrow on your skin. These organisms live harmlessly on your body until warmth and moisture allow them to multiply. As noted in Medical News Today, these fungi infect the outermost layer of your skin, and without treatment, they spread quickly to other areas.1

• Certain home remedies kill fungi as effectively as over-the-counter creams — Tea tree oil, garlic, hydrogen peroxide with iodine, and baking soda are standout remedies that directly attack fungal growth.2

A clinical study found that 25% and 50% tea tree oil solutions cured the infection in up to 64% of users, compared to only 31% with placebo.3 These results are meaningful for anyone who wants to treat athlete’s foot naturally without resorting to synthetic antifungal creams that often cause skin irritation or resistance.

• Tea tree oil disrupts fungal cell walls and reduces inflammation at the same time — Derived from Melaleuca alternifolia leaves, this essential oil contains a compound that breaks down fungal membranes. Because tea tree oil is potent, applying it with a carrier oil such as coconut oil prevents irritation. This combination works synergistically — tea tree oil fights fungus while coconut oil moisturizes and soothes cracked skin.

• Garlic is another powerful antifungal agent that works through sulfur-based compounds — Crushed garlic releases allicin, a natural antimicrobial that stops fungal replication and kills spores. A simple home remedy involves soaking your feet in warm water mixed with crushed garlic for 30 minutes twice a day.4 While it has a strong smell, garlic’s antifungal action makes it an effective, low-cost remedy that supports your body’s natural healing response.

• Hydrogen peroxide combined with iodine wipes out stubborn fungal colonies on contact — When used together, these two household antiseptics eliminate up to 16 fungal species more effectively than when used separately.5

Hydrogen peroxide releases oxygen that oxidizes fungal cells, while iodine denatures fungal proteins, rendering them inactive. This dual action also prevents secondary bacterial infections, which often occur when scratching opens small wounds on your feet. However, both solutions should always be diluted to avoid skin burns or discoloration.

• Baking soda alters your skin’s pH and reduces fungal survival — Sodium bicarbonate has mild antifungal properties that inhibit fungal enzyme activity.6 A daily 20-minute soak in a baking soda solution raises your skin’s pH to inhibit fungal growth and soothe inflammation. Once finished, feet should be dried completely without rinsing to allow a fine residue of baking soda to remain as protection.

Simple Soaks and Oils Offer Science-Backed Relief for Athlete’s Foot

A report from Health compiled findings from multiple studies evaluating home remedies for athlete’s foot and how they work to reduce fungal growth, itching, and inflammation.7 Ingredients like salt, apple cider vinegar, and natural oils interrupt fungal life cycles and restore your skin’s balance, offering practical steps that don’t rely on harsh over-the-counter creams.

• Foot baths combined with everyday kitchen ingredients act as powerful antifungal treatments — For example, a study published in PLOS One confirmed that salt disrupts fungal metabolism.8 Adding half a cup of salt to warm water and soaking your feet for 15 to 20 minutes, twice a day, helps reduce itching and redness.

• Rubbing alcohol and apple cider vinegar target fungi through dehydration and acidity — Rubbing alcohol — made of water and isopropyl alcohol — kills microbes by dissolving their outer membranes and drying them out.

Meanwhile, apple cider vinegar introduces acetic acid, a compound that lowers surface pH and interrupts fungal growth. Together, these solutions provide an environment hostile to fungal survival. Alternating between alcohol and vinegar soaks every few days keeps fungal colonies from returning.

• Tea tree oil, coconut oil, and neem oil are effective topical treatments for athlete’s foot — Tea tree oil damages fungal membranes, while coconut oil — rich in lauric and caprylic acids — kills microbes and moisturizes cracked skin.

Neem oil, derived from the seeds of the neem tree, contains compounds such as azadirachtin that reduce both fungal growth and inflammation. These oils can be safely diluted and applied two to three times a day, offering both antifungal action and soothing relief from irritation.9

The Hidden Triggers That Make Athlete’s Foot Hard to Heal

A report published by Rupa Health takes an integrative medicine approach, explaining that recurring fungal infections often signal an internal problem — such as blood sugar imbalance, gut dysbiosis, or heavy metal burden — rather than simply poor hygiene.10

While topical treatments remove surface symptoms, identifying and correcting internal imbalances leads to long-term resolution. This view challenges the conventional approach of relying solely on antifungal creams and highlights the connection between your overall metabolic health and how your skin defends itself.

• Underlying metabolic dysfunction makes you more prone to recurring fungal infections — People with blood sugar irregularities — especially insulin resistance or early diabetes — are more likely to develop athlete’s foot. High blood sugar creates an environment where fungi thrive and also weakens immune defense. Testing for fasting glucose, hemoglobin A1c, insulin, and C-peptide helps uncover hidden metabolic issues.

These tests reveal whether your cells are absorbing glucose properly or whether excess sugar is circulating in your bloodstream, feeding fungal growth. Correcting blood sugar through diet and lifestyle changes restores your body’s ability to keep fungi in check naturally.

• Gut and skin microbiome imbalances weaken your natural defense barrier — The health of your gut determines how your immune system responds to fungal invaders. When your gut microbiota — your internal ecosystem of microbes — becomes unbalanced, it increases inflammation and compromises your skin’s ability to resist infections.

Comprehensive stool tests reveal whether harmful bacteria or yeasts have overtaken beneficial microbes. Markers like zonulin, which measures intestinal permeability or “leaky gut,” show how fungal skin infections and digestive issues are often linked. By improving gut health, you improve immune balance and reduce the frequency of skin flare-ups.

• Environmental toxins and heavy metals further suppress immune resilience — Toxic buildup from sources like contaminated water, old dental fillings, or industrial pollution burdens your immune system. This chronic exposure makes it harder for your body to fight off everyday pathogens, including fungi.

Heavy metal testing helps identify whether toxins are contributing to repeated athlete’s foot infections. Once identified, supporting detoxification through nutrients and improved mitochondrial function helps restore immune strength.

• Topical probiotics restore balance to your skin microbiome and reduce relapse — The report highlights emerging research on applying probiotics directly to your skin to restore microbial balance. These beneficial bacteria occupy the same niches that harmful fungi use, preventing reinfection while calming inflammation. For people who experience frequent athlete’s foot flare-ups, this approach supports long-term resilience rather than temporary relief.

• The most successful results come from addressing both the internal and external triggers — Combining functional testing with targeted lifestyle changes gives you control over your recovery. By stabilizing blood sugar, improving gut health, and detoxifying heavy metals — alongside applying natural antifungal and probiotic remedies — you strengthen your body’s defenses from the inside out.

This layered approach turns treatment into a measurable process: as your gut balance improves, your skin clears, and your risk of recurrence drops dramatically.

How to Stop Athlete’s Foot at the Source and Keep It from Coming Back

If you’ve battled athlete’s foot more than once, you know how frustrating it is to treat the itching only to have it return weeks later. The key isn’t just killing the fungus — it’s changing the environment that allows it to thrive. Fungi feed on moisture, dead skin, and a weakened skin barrier. By restoring balance from the inside out and maintaining dry, resilient feet, you break the cycle for good. Here’s what I recommend you do to restore your skin’s defenses and stop athlete’s foot from coming back.

1. Strengthen your body’s defenses from within — If you’ve had repeated fungal infections, your immune or metabolic health needs attention. Elevated blood sugar and poor gut health feed fungal growth. Focus on reducing ultraprocessed foods, including seed oils high in linoleic acid, and increasing healthy carbs and other whole foods.

Carbs are key for giving your cells energy, especially since glucose is what your mitochondria (the powerhouses in your cells) love to use. To keep your gut happy, aim for about 250 grams of carbs a day. This step boosts your energy and supports your gut health.

Start slow with gentler options like white rice or whole fruits to let your gut adjust without causing trouble. Later, add veggies, whole grains, or starches as long as they’re well-tolerated. If your gut’s already struggling, hold off on high-fiber foods at first — too much fiber stirs up harmful toxins in your gut if it’s not healthy.

Once your gut feels better, eat more fiber. Fiber is the primary fuel for your beneficial gut microbes, allowing them to produce short-chain fatty acids like butyrate that strengthen your gut barrier. Also eat more resistant starches like cooked-then-cooled potatoes or green bananas — they fuel butyrate production.

2. Dry your feet completely every time you bathe or sweat — After showering, take an extra minute to dry between your toes with a clean towel or a hair dryer set to low heat. Fungus thrives in moisture, so leaving even a small amount of dampness invites it to return. Once dry, dust your feet with baking soda to absorb sweat and keep your skin cool throughout the day. If your shoes or socks feel damp, change them right away instead of letting them air-dry while you wear them.

3. Use natural antifungal soaks and oils consistently — Natural ingredients work best when used regularly, not just when symptoms flare. Mix half a cup of baking soda or salt into warm water and soak your feet for 20 minutes twice a day. These soaks change your skin’s pH, making it difficult for fungi to survive.

After soaking, apply a blend of diluted tea tree oil and coconut oil to the affected areas. The tea tree oil kills fungal cells, and the coconut oil repairs cracks and strengthens your skin barrier.

4. Try a dimethyl sulfoxide (DMSO) and vinegar solution for stubborn infections — If your infection lingers despite routine care, try a topical solution combining DMSO and vinegar. DMSO helps carry the vinegar’s acetic acid deep into your skin, where the fungus hides, improving absorption and accelerating healing. If you decide to try this, apply it with a cotton pad to clean, dry skin and allow it to air dry completely before putting on socks or shoes.

5. Rotate your shoes and make smart hygiene choices — Fungi hide in the lining of shoes, especially tight or synthetic pairs that trap heat. Rotate your footwear daily to let each pair dry for at least 24 hours before wearing them again. Choose leather, canvas, or mesh shoes, and avoid plastic or rubber styles. Socks made from wool or bamboo pull sweat away from your skin. If you tend to sweat heavily, carry an extra pair of socks to change into mid-day.

Wash your feet nightly, clean your shower floor weekly, and don’t share towels, socks, or shoes. If you swim or use a gym, wear sandals in locker rooms and pool areas to block fungal exposure. By changing both your external environment and internal balance, you remove what the fungus depends on to survive. With these steps, you’ll not only eliminate athlete’s foot — you’ll build lasting resistance against it.

FAQs About Athlete’s Foot

Q: What actually causes athlete’s foot to keep coming back?
A: Fungi thrive in warm, moist environments — like sweaty shoes, damp socks, or areas between your toes that stay wet after bathing. If your skin barrier or immune system is weak, or if you wear tight or synthetic footwear, the fungus easily multiplies and returns even after treatment. Hidden factors such as blood sugar imbalance, gut dysbiosis, or toxin overload also make it harder for your body to keep fungal infections under control.

Q: Which natural remedies work best for treating athlete’s foot?
A: Several natural options are backed by research. Tea tree oil and garlic both destroy fungal membranes and reduce inflammation. Hydrogen peroxide mixed with iodine kills multiple fungal species at once, while baking soda soothes itching and shifts your skin’s pH to make it less hospitable to fungus. Salt and vinegar soaks, rubbing alcohol, and oils such as coconut and neem also help clear infection and restore healthy skin.

Q: How does DMSO with vinegar help stubborn fungal infections?
A: A topical mix of DMSO and food-grade vinegar has been found to be highly effective. This combination works because DMSO carries vinegar’s acetic acid deep into your skin, killing fungus at its root and helping the tissue heal faster.

Q: What lifestyle changes prevent athlete’s foot from returning?
A: Keeping your feet dry is essential. Always dry between your toes after bathing, use baking soda to absorb moisture, and wear breathable socks and shoes. Rotate your footwear to give each pair time to dry, and avoid walking barefoot in public locker rooms or pool areas. Inside your home, clean showers regularly and change socks daily to prevent reinfection.

Q: How does improving gut and metabolic health help stop athlete’s foot?
A: Your skin and gut are connected through your immune system. When your gut microbiome is balanced, your body is better equipped to fight fungal overgrowth naturally. Eating fewer ultraprocessed foods, lowering seed oil intake, and increasing nutrient-dense carbohydrates help stabilize blood sugar and support beneficial gut bacteria. This inside-out approach restores your body’s natural resistance so the fungus has nowhere to thrive.

Cortisol is built for emergencies, but modern life keeps it switched on 24/7. Designed to help you react fast in moments of danger, this hormone floods your system with energy when you need to fight or flee. But when the stress rarely stops, your cortisol doesn’t either. That’s when the very system meant to protect you begins to do damage.

You’re probably not sprinting from wild animals, but your body reacts the same way to constant deadlines, poor sleep, and emotional stress. Over time, that daily grind trains your body to live in survival mode. You stop recovering properly. Your energy dips. Your digestion slows. You store more fat, especially around your belly, and lose muscle even when you’re trying to stay active.

What makes this worse is how invisible it often is at first. You might feel tired, edgy, or wired at night. But underneath, your body is running on empty while cortisol stays elevated. And the longer that goes on, the more your hormone rhythms, metabolic function, and immune defenses unravel.

This isn’t about managing stress in the abstract — it’s about restoring your body’s ability to reset. If you’re feeling burned out, inflamed, or like your system is stuck in overdrive, there are simple, science-backed ways to flush out the excess and bring things back into balance.

Simple Habits That Help Flush Cortisol Naturally

A featured article in Vogue highlights advice from physician Dr. Liza Osagie-Clouard and registered dietitian Jodie Relf.1 It explores how to support your body’s natural cortisol-clearing processes through lifestyle changes, not medication. Their approach is built around simple tools — breathwork, sleep, movement, and blood sugar balance — that anyone can apply, even if you’re overwhelmed or short on time.

• People dealing with chronic stress symptoms benefit most from these changes — This information is aimed at people who feel “wired but tired,” have trouble sleeping, gain weight around the midsection, or struggle with irritability and sugar cravings. These signs point to cortisol overload, which is often worsened by morning coffee on an empty stomach or overtraining without proper rest.

• Breathwork stands out as a fast, drug-free tool to bring cortisol down — Dr. Osagie-Clouard recommends lengthening your exhale to shift your body into a parasympathetic state — the “rest and digest” mode that opposes stress activation. A quick version of this is the “parasympathetic sigh,” where you inhale, then take a second sip of air before slowly releasing it. This practice gives your nervous system the green light to relax and helps your body flush out excess cortisol naturally.

• Caffeine is a silent contributor to cortisol overload but timing matters — There’s a downside to relying on coffee to get through the morning fog, especially on an empty stomach. “Coffee is a stimulant which will raise cortisol levels,” says Relf. Having it before eating keeps you stuck in the stress cycle. Instead, wait until after breakfast, or reduce intake altogether if you already feel overstimulated. You don’t have to eliminate caffeine entirely, just shift when and how you drink it.

• Gentle exercise like walking reduces cortisol more effectively than high-intensity workouts — Forget marathon gym sessions. Regular, moderate movement helps balance cortisol levels without triggering more stress. The key is consistency, not intensity. People with polycystic ovary syndrome (PCOS) or adrenal imbalances often see the greatest benefit from low-impact activities, which also improve insulin sensitivity and emotional resilience.

Reset Your Hormones by Fixing Sleep, Stabilizing Blood Sugar, and Finding Joy

If you’re tossing and turning at night, your cortisol rhythm is likely reversed — too high in the evening and too low in the morning. The solution isn’t just sleep quantity but bedtime rituals. A consistent sleep-wake time, along with calming wind-down habits like dim lights or reading, help your cortisol follow its natural cycle again.

• Blood sugar swings worsen cortisol imbalances — balanced meals are key — Spiking your glucose leads to more cortisol as your body scrambles to restore balance. Try pairing carbs with healthy fats and protein to slow absorption. Instead of eating fruit alone, combine it with raw, grass fed yogurt to reduce the sugar spike. That simple change lessens the hormonal stress response and leaves you with steadier energy.

• Ashwagandha supports cortisol regulation if used consistently and wisely — As an adaptogen, ashwagandha helps your body become more resilient to stress. Research shows that 250 milligrams (mg) to 800 mg daily for eight weeks led to measurable drops in cortisol.2 But sourcing matters. Look for 100% organic ashwagandha root, free of fillers, additives, and excipients. Unfortunately, adulterated ashwagandha products have been found on the market, so buyer beware.

• Spirituality, laughter, and fun are underrated cortisol detoxifiers — For people with a spiritual practice, prayer has been shown to lower cortisol and increase calm during life stress.3 If you’re not spiritual, the same benefits show up through meditation, community connection, or simple pleasures like laughter.4

Chronically Elevated Cortisol Throws Off Nearly Every Major Body System

Often labeled merely as a stress hormone, cortisol fulfills many other functions within your body. Its main role is to act as a vital defense mechanism, ensuring that your blood glucose levels don’t plummet to hazardous lows. By maintaining these levels, cortisol safeguards you against the severe danger of a hypoglycemic coma.5

Although cortisol’s actions are beneficial in the short term, consistently high levels negatively impact your health. As noted by the Cleveland Clinic, cortisol is a master regulator that affects your metabolism, sleep rhythm, blood pressure, inflammation, and immune defense.6 Chronic high cortisol damages these systems one by one. When left unchecked, the result is often accelerated aging, insulin resistance, and persistent fatigue that no amount of rest can fix.

• This is especially dangerous for people with hormonal imbalances or metabolic issues — Cortisol’s wide-ranging effects become especially harmful when your body’s regulatory loop — managed by your brain and adrenal glands — breaks down. Your hypothalamus, pituitary gland, and adrenal glands work as a team to keep cortisol in balance. But chronic stress overrides this system, causing dysfunction that leads to everything from sleep disruption to hormone depletion.

• Cortisol pushes blood sugar up, then blocks insulin from doing its job — When you’re stressed, cortisol signals your liver to release glucose so you have immediate energy. That part is normal. The problem comes when that stress doesn’t end. Cortisol also suppresses insulin — the hormone that helps move sugar into your cells for fuel. That double action creates blood sugar spikes followed by crashes, which leave you wired, hungry, moody, and ultimately insulin resistant over time.

• Over time, your immune system stops responding to cortisol at all — Short bursts of cortisol help tamp down inflammation, which is how your body prevents overreaction to stress or infection. But with constant elevation, your immune system becomes desensitized to cortisol’s signal. That means more inflammation, more infections, and slower recovery from illness. You feel run down, get sick more often, and take longer to heal, even from minor cuts or colds.

• Cortisol throws off blood pressure regulation and muscle metabolism — Cortisol influences blood pressure, though the exact mechanics aren’t fully understood. What is known is that people with chronically high cortisol often have high blood pressure. Additionally, cortisol breaks down muscle tissue to free up amino acids for emergency energy use. In a prolonged stress state, this leads to muscle wasting, physical weakness, and slower metabolic function.

• Without action, elevated cortisol creates long-term metabolic damage — The longer cortisol remains out of balance, the more entrenched the damage becomes. Chronically high cortisol leads to conditions like Type 2 diabetes, osteoporosis, immune dysfunction, and in extreme cases, Cushing’s syndrome — a hormonal disorder marked by fat accumulation in the face and abdomen, muscle loss, and stretch marks.

Enjoyment, Breathwork, and Light Movement Lower Cortisol Fast

You don’t need expensive programs or clinical interventions to reduce cortisol — just daily behaviors that align with how your body naturally resets stress. Fun, healthy food, and movement are among the most underused remedies for stress overload.7

• Breathwork methods like the 4-7-8 technique directly influence the vagus nerve — This technique involves inhaling for four seconds, holding for seven, and exhaling for eight. Doing just a few rounds shifts your nervous system out of the “fight or flight” state and into the relaxation zone. Activating the vagus nerve — your body’s command switch for rest — lowers cortisol almost immediately and helps prevent your brain from getting stuck in stress loops.8

• Spending time with pets lowers stress markers through oxytocin release — Even a few minutes of petting a friendly dog or cat is enough to lower cortisol and increase oxytocin — a hormone linked to bonding, calmness, and trust.9 This is one of the fastest and most accessible ways to buffer cortisol spikes, especially if you feel isolated or overstimulated by daily demands.10

• Blue light exposure after sunset disrupts your body’s hormonal clock — Staring at phones or tablets at night keeps your brain locked in daytime mode. Blue light suppresses melatonin (your sleep hormone) and increases cortisol at exactly the wrong time. Shut off screens at least 60 minutes before bed or use blue-light blocking glasses to minimize the damage. Also opt for warmer, dimmer lighting in your home as it gets dark.

• Even food choices influence your cortisol rhythm — Fermented foods like kimchi, kefir, and sauerkraut are helpful for stress because they support gut health. Gut bacteria are directly linked to your brain’s emotional center, so improving your digestion improves how you process stress. Staying hydrated also helps — dehydration is a common trigger for temporary cortisol spikes, especially in the afternoon slump.

• Doing what you enjoy resets your stress response naturally — Whether it’s gardening, painting, or listening to music, joy acts as a cortisol buffer. Your body isn’t wired to stay in survival mode when you’re actively engaged in something meaningful. Fun isn’t optional — it’s a necessary signal that tells your brain you’re safe again.

Simple Steps to Reset Cortisol and Calm Your Stress System

If your stress feels like it’s running the show, you’re not imagining things — chronically high cortisol throws off everything from your mood to your metabolism. But it’s not permanent. You can reset your body’s stress response by making small, consistent changes that address the root cause: a nervous system stuck in overdrive, poor blood sugar control, and an overloaded lifestyle.

Whether you’re exhausted, wired, or feeling like your body just isn’t recovering like it used to, these are the steps I recommend to restore balance and help your body flush excess cortisol naturally. Here’s how to start:

1. Eat enough healthy carbs to stop cortisol spikes — If you’ve been cutting carbohydrates, your body is stuck in a stress pattern. Cortisol rises every time your blood sugar dips too low, so increasing healthy carbohydrate intake helps lower cortisol levels. Start by aiming for 250 grams of carbs per day, which supports sustained metabolic health and ensures that your mitochondria function efficiently.

Prioritize easy-to-digest options like fruit and white rice. When your gut is ready, meaning no bloating and no irregular bowel movements, gradually add in root vegetables, then legumes, additional vegetables, and well-tolerated whole grains.

2. Cut back on endurance exercise and overtraining — If you’re doing long cardio sessions, distance running, or frequent high-intensity interval training, you’re telling your body it’s constantly under threat. That pushes cortisol higher. Switch to shorter, gentle strength training, walking, dancing, or swimming. If you feel worse after a workout instead of better, that’s your body telling you it’s time to pull back.

3. Reset your nervous system with breathwork and rhythm — Use breathing techniques like the 4-7-8 method or a parasympathetic sigh to shift your body out of fight-or-flight mode. The 4-8 breathing technique — inhale for four seconds, pause, then exhale slowly for eight — also stimulates your vagus nerve and quickly lowers cortisol, guiding your body into a calmer, more restorative state.

This isn’t just mental — it’s physical. The longer your exhale, the more your vagus nerve activates, which tells your whole body, “You’re safe.” Do this before bed, when you’re feeling overwhelmed, or after meals to support digestion and hormone balance.

4. Make sleep non-negotiable — and fix your light exposure — Your cortisol rhythm depends on your circadian clock. That means getting bright morning sunlight and avoiding screens and dimming lights after sunset. Keep your bedtime and wake-up time as consistent as possible. If you’re dragging during the day, don’t depend on coffee — look at your sleep first. Rest is not a luxury. It’s how your body resets and clears out stress hormones.

5. Use natural progesterone to calm your brain and body — Natural progesterone is one of the most effective and affordable ways to bring your stress hormones back under control. Unlike synthetic progestins, natural progesterone is a hormone your body already recognizes and responds to. It acts directly as a cortisol blocker, helping lower the amount of cortisol circulating in your bloodstream and dialing down the stress response at its source.

FAQs About Cortisol

Q: What is cortisol, and why is it harmful when it’s too high for too long?
A: Cortisol is your body’s primary stress hormone. It’s designed to help you respond to immediate danger by raising blood sugar, blood pressure, and alertness. But when cortisol stays high for extended periods — due to ongoing stress, poor sleep, or overtraining — it disrupts nearly every system in your body. Long-term high cortisol contributes to belly fat, blood sugar imbalances, weakened immunity, sleep problems, and even muscle loss.

Q: How do I know if my cortisol is too high?
A: Common signs of chronically high cortisol include feeling wired but tired, difficulty falling asleep, belly fat that won’t budge, sugar and salt cravings, frequent illness, and irritability. You might also notice thinning hair, blood sugar crashes, or anxiety. These symptoms often worsen over time if the underlying stress isn’t addressed.

Q: What lifestyle habits help lower cortisol naturally?
A: Gentle daily habits like walking, breathwork (such as the 4-7-8 method), consistent sleep routines, and eating healthy carbohydrates all help your body reset cortisol levels. Avoiding blue light at night, reducing caffeine, and making time for joy or relaxation — like spending time with pets or enjoying hobbies — are also effective tools to calm your stress response.

Q: Why is sleep so important for cortisol balance?
A: Cortisol follows a daily rhythm — it should be highest in the morning and lowest at night. Poor or irregular sleep reverses that rhythm, making it harder for your body to recover and regulate inflammation. A fixed bedtime, morning sunlight, and avoiding screens at night help restore this natural cycle so cortisol doesn’t stay elevated after dark.

Q: How does natural progesterone help bring stress hormones back into balance?
A: Natural progesterone is a safe, effective, and affordable way to lower excess cortisol. It works as a direct cortisol blocker, reducing the amount of this stress hormone circulating in your system. Unlike synthetic progestins, natural progesterone supports your body’s own hormone rhythms without adding to the burden.

Insulin resistance — a metabolic condition characterized by fatigue, abdominal weight gain, brain fog, and unstable blood sugar — now sits at the center of cancer research. Unlike a single blood test result, insulin resistance reflects how your cells respond to insulin over time.

This means glucose struggles to enter cells efficiently. Your mitochondria — the thousands of tiny power plants inside each cell that convert food into usable energy — lose their steady fuel supply, and energy production becomes erratic.

From a clinical perspective, insulin resistance often develops years before diabetes appears, which explains why many people live with symptoms without recognition. When insulin signaling breaks down, chronic inflammation and elevated insulin levels create biological signals that encourage abnormal cell growth and disrupt normal cellular repair.

Now, a large-scale analysis has used machine learning to connect this metabolic dysfunction directly to cancer incidence — revealing which cancers are most affected, why body weight alone misses the real risk, and how insulin resistance acts as an early warning signal across multiple organs.1

AI Model Reveals Insulin Resistance as a Cancer Risk Signal

For a study published in Nature Communications, researchers built a machine-learning model that predicts insulin resistance before diagnosable disease develop.2 Instead of relying on one lab test, the model looked at everyday health data — things like age, blood sugar, and triglycerides.

It calculated whether someone’s Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) score crosses a level that signals meaningful insulin resistance. HOMA-IR is a simple score calculated from fasting blood sugar and insulin levels that estimates how resistant your cells have become to insulin. The model was applied to the UK Biobank, which tracks long-term health data from adults ages 40 to 69.3

Among the 372,395 people who didn’t have cancer at the start, 51,193 were diagnosed during follow-up. Individuals flagged as insulin resistant consistently showed higher rates of diabetes, heart problems, and several cancers. This tells you risk builds years before diagnosis — which means prevention is still possible.

• Certain cancers showed stronger links to insulin resistance — Researchers reported connections to 12 cancer types overall, with the largest increases seen in uterine cancer (about 134% higher risk), kidney cancer (about 56% higher risk) and esophagus cancer (about 46% higher risk).
Pancreatic cancer risk rose roughly 29%, colon cancer 18%, and breast cancer 13% — all in individuals flagged as insulin resistant. Insulin resistance was not tied to one organ — it appeared across multiple systems, shifting it from a blood sugar issue into a whole-body metabolic warning signal.
• Metabolic health mattered more than body weight alone — People with higher body weight but no insulin resistance didn’t show the same risk pattern. Meanwhile, those with insulin resistance did — even when body weight looked similar. This means your metabolic function — how your body handles energy — provides more meaningful information than the number on a scale.
The connection between insulin resistance and cancer showed up in younger adults and older adults alike. The effect also stood out in people with a history of smoking, especially former smokers, where insulin resistance amplified risk. Your past exposures and current metabolic health interact, which explains why risk looks different from one person to another.
• Insulin resistance showed clear early disease timelines — Over several years of follow-up, people flagged as insulin resistant developed diabetes far more often, with more hospital admissions related to metabolic disease. One analysis showed more than seven-fold higher odds of developing diabetes during follow-up. That timeline highlights something important: insulin resistance shows up long before major disease, giving you measurable signals to act on.
• High insulin acts like a growth signal inside your body — When cells stop responding well to insulin, your body releases more of it to compensate. Elevated insulin then interacts with growth pathways that control how cells divide and survive. When that signal stays high for years, it creates conditions where abnormal cells gain an advantage — one of the earliest steps in tumor development.
Specifically, elevated insulin activates the IGF-1 (insulin-like growth factor) signaling pathway, which tells cells to grow and divide faster — and suppresses the normal “self-destruct” signals that clear out damaged cells before they become dangerous.
• Ongoing inflammation creates a favorable environment for tumors — Insulin resistance often exists alongside chronic low-grade inflammation. This type of inflammation changes the environment around cells so damaged cells persist longer than they should. Metabolic stress and cancer risk move together because they share the same biological environment.
• Machine learning creates a practical “digital biomarker” for early action — Researchers described the concept of AI-derived insulin resistance as a digital biomarker — a single score that combines multiple metabolic signals into one risk indicator.
Instead of waiting for disease, this approach allows earlier monitoring and more targeted screening. That makes insulin resistance something visible and measurable over time, giving you a clearer way to track improvement rather than guessing about your metabolic health.

How to Remove the Drivers of Insulin Resistance

The research makes the risk clear — but it also reveals something empowering: insulin resistance is measurable and reversible. Insulin resistance develops when your cells struggle to receive glucose and mitochondria — the part of your cells responsible for producing energy — lose steady fuel. The priority is removing what blocks insulin signaling. When cellular energy production recovers, the entire disease trajectory shifts — including cancer risk.

As metabolic function improves, your cells produce more ATP (adenosine triphosphate) — the energy currency that powers virtually every cellular process — inflammatory signals drop and the reinforcing cycle between insulin resistance and mitochondrial dysfunction begins to reverse. The following steps address the root cause.

More than 60 million Americans deal with heartburn each month,1 and for millions of them, relief comes in the form of over-the-counter or prescription acid blockers. These drugs — proton pump inhibitors, or PPIs — promise fast, long-lasting relief. But they also come with risks few people are told about.

What starts as a simple fix for reflux often becomes a long-term dependency that disrupts far more than digestion. These drugs don’t just neutralize acid; they shut down the very pumps your stomach uses to create it. That’s a problem because stomach acid isn’t a disposable nuisance; it’s essential for breaking down food, absorbing nutrients, and defending your gut from harmful microbes.

When that system is thrown off, your health begins to unravel in unexpected ways. The deeper issue isn’t just that acid is suppressed — it’s that your body didn’t need suppression in the first place. The real cause of reflux, for most people, is low stomach acid, not too much of it. And when PPIs suppress it even further, the result is fermentation, bloating, and pressure that pushes acid up into your esophagus.

But the concern doesn’t end in your gut. Long-term PPI use increases your risk of cardiovascular events, even if you have no history of heart disease.2 That includes heart attacks and death from heart-related causes. If you’re taking these drugs daily, thinking they’re harmless, it’s time to look at what the science actually says — and what safer, root-cause solutions are available.

Popular Heartburn Drug Linked to Higher Heart Attack Risk

In a large-scale analysis published in PLOS One, scientists from Stanford University reviewed more than 16 million electronic clinical documents covering 2.9 million patients.3 Their goal was to determine whether PPIs — drugs like omeprazole (Prilosec) and esomeprazole (Nexium) — were associated with cardiovascular events, specifically heart attacks.

• The population studied included people with acid reflux but no heart disease — The researchers focused on adults with gastroesophageal reflux disease (GERD), the most common reason PPIs are prescribed.

They isolated individuals who had GERD but had not suffered a heart attack before. Importantly, they excluded people taking clopidogrel, a blood thinner often prescribed after a heart attack, to rule out drug interactions. This allowed them to evaluate how PPIs affect the general population, not just those at high cardiovascular risk.

• PPIs were linked to a 16% higher heart attack risk — The data revealed that GERD patients who used PPIs were 1.16 times more likely to experience a heart attack compared to those who didn’t take these medications. This increase was found in multiple datasets and remained consistent across different PPI brands.

• PPI users faced double the risk of dying from heart problems — In a long-term study of 1,503 adults who underwent heart imaging, researchers followed participants over several years.

They found that people taking PPIs were twice as likely to die from cardiovascular events, like heart attacks, strokes, or cardiac arrest, compared to those not taking the drugs. This increased risk remained even after accounting for factors like blood pressure and smoking history.

• H2 blockers did not show the same cardiovascular risks — To compare drug types, researchers also studied H2 blockers like famotidine (Pepcid), which reduce stomach acid by a different mechanism. Unlike PPIs, H2 blockers showed no increased risk of heart attack or cardiovascular death. This key distinction suggests the problem is something unique to how PPIs work.

• The biological mechanism involves a molecule that blocks nitric oxide — PPIs interfere with an enzyme responsible for breaking down a naturally occurring molecule that inhibits nitric oxide production. Nitric oxide is essential for healthy blood vessels, helping them stay relaxed, elastic, and resistant to clots.

Without enough of it, the lining of your blood vessels stiffens and becomes inflamed. In vein samples from coronary bypass patients, PPIs were shown to suppress nitric oxide production, confirming the drug’s impact on actual human blood vessels, not just cells in a lab.

Heartburn Drugs Silently Damage Your Kidneys, Bones, and Brain Over Time

Millions of Americans are taking PPIs without understanding the risks. These drugs are among the most popular in the world, with over 15 million U.S. users and billions in global sales.4 Beyond cardiovascular concerns, PPIs are associated with a wide range of long-term complications, many of which emerge silently and go undetected until damage is advanced.

• PPIs affect kidneys, bone density, and your nervous system — Long-term use of PPIs has been linked to serious kidney disorders such as chronic kidney disease,5 acute kidney injury and end-stage renal disease.

I’ve written before about the many health benefits of aspirin that many people don’t hear about — from protecting your heart and preventing cancer to boosting your metabolism and balancing your hormones.

But new research is revealing something about aspirin and cancer that changes the story in ways nobody expected. It starts with a completely different way of looking at what drugs actually do to cancer cells. And it ends with a finding that turns decades of assumptions upside down.

How Cancer Drugs Have Always Been Tested — and Why It Misses So Much

For as long as modern cancer research has existed, scientists have tested drugs the same basic way. They put cancer cells in a dish, add the drug, and wait to see if the cells die. If most of them die, the drug is a winner. If they survive, the drug gets tossed.

This sounds perfectly reasonable. But stop and think about what it actually measures. It measures one thing and one thing only: death. Here’s the problem with that.

• Cancer isn’t just one thing going wrong — A cancer cell is a normal cell that has gone haywire in many ways at the same time. Think of it like a car where the engine is racing, the brakes are cut, and the steering is locked — all at once. Killing the car — running it into a wall — is one way to stop the problem. But what if you could just fix the engine, unlock the steering, reconnect the brakes, and turn the headlights back on? You would have a working car again.
• Cancer cells aren’t alien invaders — They’re your own cells running the wrong program. And a drug that could fix part of that program — slow the engine down, reconnect some of the brakes — would be completely invisible in the standard drug test, because the cells didn’t die. How many valuable drugs have been thrown in the trash because we were only looking at one thing?

Every Cell Runs a Program — Cancer Cells Are Running the Wrong One

To understand the new approach, you first need to understand one simple idea about how your cells work.

• Every cell in your body contains the same DNA, the same complete set of instructions — What makes a colon cell different from a brain cell or a skin cell is not which instructions they have, but which instructions they’re actually using. Out of roughly 20,000 genes, each cell type switches on a specific set and keeps the rest turned off. This pattern — which genes are on and which are off — is the cell’s program. It is what gives the cell its identity.
• Think of it like a massive mixing board in a recording studio — There are 20,000 sliders. A healthy colon cell has each slider set to a very specific position. The overall setting produces “healthy colon cell.” When a cell becomes cancerous, the sliders get moved. Some that should be turned down get cranked up. Others that should be up get pushed to zero.

The mixing board is still there, the sliders still work, but the overall setting now produces “cancer cell” instead of “healthy colon cell.” This is a crucial point. The cancer cell hasn’t been destroyed or replaced. It’s your cell, running the wrong settings.

A 100-Million-Cell Dataset Made a New Question Possible

Researchers at a company called Tahoe Therapeutics have built something that has never existed before.1 They measured how 1,100 different drugs changed the genetic settings in cancer cells — one cell at a time — across 50 different cancer cell lines. The result is a dataset containing 100 million individual cell measurements from 60,000 separate drug experiments. That’s 50 times more data than everything publicly available before it — combined.

• With this enormous dataset, they could finally ask the question that nobody had enough data to answer before — For every drug, does it push the cancer cell’s gene settings back toward the healthy pattern? Here’s how they did it. First, they used data from real colon cancer patients to map out exactly how the gene settings differ between healthy colon tissue and cancerous colon tissue. That gave them the “disease signature” — a precise measurement of what went wrong.
• Then, for each drug in their collection, they measured what it did to the mixing board — Did it move the sliders back toward the healthy positions? Or did it push them even further in the wrong direction? Or did it just move them to some random new pattern?
• They scored every drug with a simple number — A strong negative score meant the drug was reversing the cancer pattern — pushing the cell back toward normal. They call this “cell-state reversal.”2

The First Test: Does It Match What Doctors Already Know?

Before you trust a new method, you need to check it against reality. If drugs that are already proven to work in colon cancer patients don’t score well on this test, the whole approach is worthless. So, the researchers checked. And the results were clear.

• Top-scoring drugs matched the exact mutations driving colon cancer growth — The drugs that scored highest for pushing colon cancer cells back toward normal were exactly the ones that target the specific genetic mutations most commonly found in colon cancer — MEK inhibitors, BRAF inhibitors, KRAS inhibitors, and PI3K pathway inhibitors.
These are the drugs oncologists already use because clinical experience has shown they work. The framework figured this out on its own, from the data alone, without being told which drugs are effective in patients.
• It even caught subtleties that match real clinical practice — Among chemotherapy drugs, the ones that target DNA — like 5-fluorouracil and oxaliplatin, which are the backbone of standard colon cancer treatment — scored higher than the ones that target the cell’s internal scaffolding, called microtubule inhibitors. Microtubule inhibitors aren’t part of the standard treatment for colon cancer, and the data reflected that perfectly.

Now Here’s Where It Gets Really Interesting: The Aspirin Surprise

Among all the drugs tested, one result stood out as genuinely unexpected. It involved one of the cheapest, oldest, and most widely available medicines on Earth.

When the researchers looked at aspirin and its close chemical relatives in the dataset, they found that sodium salicylate — which is aspirin with one specific piece removed — produced stronger cancer-state reversal than aspirin itself. To understand why this is such a big deal, you need to know one thing about aspirin’s chemistry. Don’t worry — it is simpler than it sounds.

• Aspirin’s chemical name is acetylsalicylic acid — It’s made of two parts: salicylic acid, which comes from willow bark and has been used as medicine for thousands of years, and an acetyl group, which was attached to the salicylic acid by chemists at Bayer in 1897 to make it easier on the stomach.
• That acetyl group isn’t just a packaging improvement — It’s the part that gives aspirin its most famous ability — the power to shut down an enzyme called cyclooxygenase, or COX for short. COX produces inflammatory chemicals called prostaglandins. When aspirin blocks COX, inflammation goes down.
That’s how aspirin reduces pain, reduces fever, thins your blood, and — most researchers assumed — fights cancer. Here’s the catch. If aspirin’s anticancer power comes from blocking COX, then removing the acetyl group — the part that does the COX blocking — should make it worse at fighting cancer, not better.
• But the Tahoe data showed the exact opposite — Salicylate, without the acetyl group, was better at reversing the cancer cell’s genetic program than aspirin with it. That means the cancer-fighting effect isn’t coming from COX inhibition. It’s coming from the salicylate itself — through a completely different mechanism that nobody was paying attention to.

So, What Is Salicylate Actually Doing? The Answer Is Elegant

The Tahoe data showed what salicylate does to cancer gene patterns. But other research teams have been uncovering how it does it, and the picture is remarkably coherent. Your cells have an energy sensor — think of it as a fuel gauge.

It’s a protein called AMPK, which stands for AMP-activated protein kinase, but all you need to know is that AMPK is the alarm system that goes off when your cell’s energy balance changes.3 It’s one of the most powerful metabolic switches in your body. Salicylate switches AMPK on.4 When AMPK activates, it triggers a chain of events that’s devastating to cancer cells. Here’s the chain, step by step:

• Step 1: AMPK shuts down c-MYC — One of the most important genes in cancer is called c-MYC. Think of c-MYC as the gas pedal for cell growth. In a healthy cell, it’s carefully controlled. In many cancers — especially colon cancer — c-MYC is jammed to the floor, driving the cell to grow and divide nonstop. Salicylate-activated AMPK grabs c-MYC and tags it for destruction. The gas pedal gets released.
A 2025 study using a mouse model of colon cancer confirmed this. Mice given salicylate had dramatically lower c-MYC levels in their colon cells, and they developed fewer tumors.5
• Step 2: With c-MYC gone, a protective system switches on — Here’s something beautiful about your biology. You already have a built-in tumor defense system — a set of genes that suppress cancer. One of the most important is a group of tiny molecules called miR-34a and miR-34b/c.6 These are microRNAs — small pieces of genetic material that act like off-switches for cancer-promoting genes. They work by silencing specific genes that cancer cells depend on to grow and spread.Normally, a protein called NRF2 — think of it as your cell’s fire alarm system — is supposed to activate these cancer-fighting microRNAs. But c-MYC sits on top of NRF2 and keeps it silenced. It’s like a bully sitting on the fire alarm so nobody can pull it. When salicylate removes c-MYC, NRF2 is free. It activates miR-34a and miR-34b/c. Your body’s own tumor suppression system comes back online.
• Step 3: The cancer cells lose their ability to spread — When researchers blocked miR-34a and miR-34b/c in the lab, salicylate’s ability to stop cancer cell migration and invasion largely disappeared. That tells you these microRNAs are the key weapons. Salicylate isn’t directly attacking the cancer — it’s rearming your body’s own defense system.
• And here’s the most important part — Normally, miR-34 depends on a tumor suppressor gene called p53 — often called the “guardian of the genome.” But p53 is the single most commonly broken gene in human cancer. In more than half of all cancers, p53 doesn’t work. Salicylate’s pathway bypasses p53 entirely. It activates miR-34 through NRF2 instead.

This means it could theoretically work in the very cancers that have already lost their most important natural defense, which is exactly the cancers that need help the most. None of this involves COX inhibition. None of it requires the acetyl group. This is the ancient willow bark compound doing something we are only now beginning to understand.

The Clinical Trial That Changed the Guidelines

While these laboratory discoveries were piling up, a major clinical trial was delivering results that would change how oncologists treat colon cancer. The trial used aspirin, not salicylate — but remember, your body rapidly strips the acetyl group off aspirin and converts it into salicylic acid. So, every aspirin patient in this trial was effectively being dosed with salicylate.

The ALASCCA trial, published in the New England Journal of Medicine in September 2025, was the gold standard of medical research — a double-blind, randomized, placebo-controlled trial, meaning neither the patients nor the doctors knew who was getting aspirin and who was getting a sugar pill.7

It was conducted across 33 hospitals in four countries: Sweden, Denmark, Finland, and Norway. The trial focused on patients with stage I through III colon and rectal cancer whose tumors carried mutations in something called the PI3K pathway — a growth-signaling system that, when broken, helps cancer cells multiply unchecked. You don’t need to remember that name.

What matters is that these mutations are found in more than one-third of all colorectal cancers — so this isn’t a rare subtype. It is a big chunk of patients. After surgery, patients were randomly assigned to take either 160 milligrams (mg) of aspirin or a placebo every day for three years.

• The results were remarkable — Among patients with the most common type of PI3K mutation, aspirin cut the three-year recurrence rate roughly in half — from 14.1% with placebo down to 7.7% with aspirin.
The benefit held up across every subgroup the researchers checked: men and women, all disease stages, colon and rectal cancer, and regardless of whether patients also received chemotherapy. Lead researcher Anna Martling of the Karolinska Institutet in Stockholm called it “a clear example of how we can use genetic information to personalize treatment and at the same time save both resources and suffering.”8
• The National Comprehensive Cancer Network has since updated its recommendations — This organization, which writes the treatment guidelines oncologists follow, now formally recommend genetic testing for PIK3CA mutations in stage II-III colon cancer, and for patients who carry the mutation, three years of low-dose aspirin after surgery.9 This makes aspirin one of the first dirt-cheap, widely available drugs to be officially integrated into precision cancer treatment guidelines.

Aspirin Also Helps Your Immune System See the Cancer

The ALASCCA trial proved aspirin works in patients. But there’s another dimension to the story — aspirin may also be helping your immune system do its own cancer-fighting job. A 2024 study published in the journal Cancer found that regular aspirin use was linked to activation of immune surveillance in colorectal cancer patients.10 Here’s what that means in plain English.

• Your immune system is supposed to recognize and destroy cancer cells — That’s one of its main jobs. But cancer cells are sneaky — they learn to hide from your immune system by covering up the markers that would identify them as abnormal.
• Regular aspirin use linked to less spread and stronger immune attack — The researchers found that colon cancer patients who regularly used aspirin had two things going for them. First, they had fewer cancer cells that had spread to their lymph nodes. Second, they had more immune cells infiltrating their tumors — meaning the immune system was actually showing up to fight.
• Aspirin helps cancer cells reveal themselves to immune system defenses — When they treated colon cancer cells with aspirin in the lab, they found aspirin increased the expression of a protein called CD80 on the surface of the cancer cells. CD80 is like a flag that says “I am abnormal — come get me.”
It helps cancer cells present themselves to your T cells — the soldiers of your immune system — so they can be recognized and destroyed. In simple terms, aspirin was pulling the camouflage off the cancer cells so the immune system could see them.

Aspirin’s Benefits Go Far Beyond Cancer

As I’ve detailed in previous articles, aspirin’s health benefits reach into nearly every major organ system. Here’s an updated picture based on the latest research.

• Your liver — A clinical trial found that 81 mg of aspirin daily led to a 17.3% decrease in the amount of fat stored inside liver cells over six months, while patients taking a placebo saw their liver fat increase by 30.3%.11 Aspirin also improved markers of inflammation and scarring in the liver — two key factors in the progression of fatty liver disease.
• Your blood sugar — An analysis of 16,209 adults aged 65 and older found that low-dose aspirin was associated with a 15% lower risk of developing Type 2 diabetes and a slower rise in fasting blood sugar levels over time.12
• Your survival in critical care — A large study of 146,191 intensive care unit (ICU) patients found that aspirin use during ICU stays was linked to significantly lower death rates within 28 days, particularly in patients with widespread inflammation.13
• Your brain — Research found that low-dose aspirin use for more than 10 years was associated with a 31% reduced risk of Alzheimer’s disease, a 69% reduced risk of vascular dementia, and a 54% reduced risk of dementia from any cause — particularly in patients who already had heart disease.14
• Your lungs — Aspirin has been shown to reduce the scarring process in lung tissue by switching on a cellular recycling system called autophagy — your cells’ built-in method of cleaning out damaged proteins and preventing scar tissue from building up. When researchers blocked autophagy, aspirin’s anti-scarring effects disappeared, confirming that this recycling process is how aspirin protects the lungs.15
• Your metabolism — Aspirin helps your cells burn glucose for energy, reduces the release of linoleic acid (LA) — a harmful omega-6 fat — from your fat stores, lowers your cortisol levels, and increases your metabolic rate by partially uncoupling your mitochondria.16 Think of uncoupling as your cellular engines running a bit hotter and burning more fuel, which is why aspirin may help with weight management.

What About Salicylate and Willow Bark?

The Tahoe finding — that salicylate reversed the colon cancer gene signature more strongly than aspirin — has a practical implication that’s easy to overlook. When you take aspirin, your body quickly strips off the acetyl group and converts it into salicylic acid. That is what circulates in your bloodstream. That is what your cells actually see.

• Aspirin’s lasting anticancer effects stem from its salicylate metabolite — The acetyl group does its COX-blocking work during the brief window before it gets removed, but the salicylate metabolite is what sticks around and does the long-term work.
This means the anticancer effects are most likely coming from the part of aspirin that’s identical to what you would get from willow bark — the plant medicine that humans have used for thousands of years, long before Bayer attached an acetyl group to it in 1897.
• Willow bark provides the same active compound linked to anticancer benefits — If you’re sensitive to aspirin — if it bothers your stomach or you can’t take it for other reasons — this is important news. A salicylic acid supplement or willow bark extract delivers the very compound that the largest drug-response dataset in history identified as more effective than aspirin at pushing cancer cells back toward normal.
• Standardized willow bark dosing approximates common low-dose aspirin effects — For dosage, to approximate the effects of 81 mg of aspirin, you would need 400 mg to 800 mg of willow bark extract standardized to 15% salicin. To match the effects of a full 325 mg aspirin, you would need roughly 1 to 2 grams of standardized extract.
• Immediate-release aspirin with minimal additives aligns best with research dosing — If you prefer aspirin, opt for immediate-release, uncoated versions. Avoid coated extended-release formulations because of their additives. Check the inactive ingredients list — corn starch should be the only one listed. A dosage of 81 mg to 325 mg daily, taken with your largest meal, is the range supported by the current research.

Why This Changes How We Think About Medicine

Step back for a moment and consider what’s happened here. For decades, the entire cancer drug discovery pipeline has been built around one question: does this drug kill cancer cells? Billions of dollars, thousands of clinical trials, an entire industry — all oriented around cell death as the primary measure of success.

Now, using the largest dataset of its kind ever assembled, researchers have shown that you can score drugs by a completely different measure — how well they push diseased cells back toward being healthy cells. And when they did this, the results matched known clinical reality with remarkable precision.

• More importantly, this approach revealed something that the old method couldn’t see — A simple, ancient, inexpensive compound — salicylate, the active heart of willow bark — is doing something to colon cancer cells that ranks alongside purpose-built targeted cancer drugs. Not by killing the cells. By fixing them.
• This framework applies anywhere a disease is fundamentally a cell running the wrong program — Autoimmune conditions where immune cells attack your own body. Brain diseases where neurons lose their specialized function. Scarring diseases where cells produce too much fibrous tissue.
In all of these cases, the right question is not “can we kill the cell” but “can we push the cell back toward normal.” How many other cheap, safe, widely available compounds have cancer-fighting properties that we have completely missed because we were only measuring the wrong thing? We may be about to find out.

The Bottom Line

We’ve spent decades arguing about aspirin and cancer while asking the wrong questions. We asked whether aspirin kills cancer cells. The answer was not very impressive. We asked whether aspirin’s anti-inflammatory COX inhibition reduces tumor-promoting inflammation. The evidence was mixed.

But now, using 100 million cell measurements and a fundamentally different scoring method, we can see that salicylate — the ancient compound at the heart of aspirin, the same molecule found in willow bark — is doing something far more sophisticated than anyone imagined.

It’s not just killing cancer cells or reducing inflammation. It switches on your cells’ energy sensor, shuts down a major cancer-driving gene, reactivates your body’s built-in tumor defense, and pushes cancer cells back toward normal.

And it does all of this through a pathway that has nothing to do with COX inhibition — the mechanism many people assumed was responsible. This is a common, safe, inexpensive medicine whose full power we are only now beginning to understand — and it deserves far more attention than it’s getting.

FAQs About Aspirin and Cancer

Q: Why are researchers rethinking how aspirin affects cancer?
A: A drug-testing framework analyzed about 100 million individual cell measurements to see whether drugs push cancer cells back toward a healthy state rather than simply killing them. Using this method, salicylate — aspirin without its acetyl component — ranked higher than aspirin at reversing the gene patterns associated with colon cancer, suggesting the anticancer effect works through a different mechanism than previously assumed.

Q: What part of aspirin appears responsible for the cancer-related effects?
A: Evidence indicates the salicylate portion — the same compound derived from willow bark — drives the key biological changes. After ingestion, aspirin is rapidly converted into salicylic acid in your body, which persists longer in circulation and is likely responsible for many downstream cellular effects linked to tumor suppression.

Q: How does salicylate influence cancer biology at the cellular level?
A: Research shows salicylate activates AMPK, a cellular energy sensor that suppresses the cancer-promoting gene c-MYC and enables activation of tumor-suppressive microRNAs such as miR-34. This pathway operates even when p53 — commonly impaired in cancer — is dysfunctional, which helps explain broad relevance across tumor types.

Q: What clinical evidence supports aspirin use in colorectal cancer?
A: A randomized clinical trial published in The New England Journal of Medicine found daily aspirin after surgery reduced three-year recurrence from 14.1% to 7.7% among patients with PI3K-pathway mutations.17 These findings contributed to updated guidance recommending genetic testing for PIK3CA mutations and consideration of post-surgical low-dose aspirin in eligible patients.

Q: How do aspirin and willow bark compare in practical terms?
A: Because aspirin is converted into salicylate, both aspirin and standardized willow bark extracts deliver related active compounds. Approximate equivalence described in research discussions suggests 400 to 800 mg of willow bark extract standardized to 15% salicin corresponds to typical low-dose aspirin exposure, while higher extract amounts may approximate full-strength aspirin ranges. Clinical dosing equivalence remains an area of ongoing research.
