After heavy sweating, the instinct is to reach for water, and plenty of it. But replacing lost fluid may not be as simple as drinking more, and a study of firefighters recovering from extreme heat exposure suggests that water alone can leave the body short of full hydration. The reason has less to do with how much you drink than with what your sweat carries away.

Strenuous activity costs you far more than fluid. Sweat carries off sodium, potassium, and other electrolytes that regulate fluid balance, nerve signaling, and muscle function. As those losses mount, dehydration sets in, marked by excessive thirst, fatigue, reduced exercise capacity, dizziness, and slower recovery. Left unchecked, it undermines thermoregulation, your body’s ability to control its temperature, and compounds the strain of whatever activity follows.

That points to something easy to overlook: relieving thirst and restoring hydration are not the same thing. If water falls short after heavy sweating, the real question is what your body needs to recover, and why electrolyte-containing drinks appear to deliver it in the important first hour after exertion.

Electrolytes Aided Recovery in the Study

The study, published in the Journal of the International Society of Sports Nutrition, followed 24 active-duty male firefighters who completed a demanding firefighting simulation while carrying roughly 66 pounds (30 kilograms) of protective equipment and gear.1 Researchers divided the participants into three groups.

One group drank plain water, another consumed a carbohydrate-electrolyte solution, and a third received the same electrolyte drink with added menthol, a compound that creates a cooling sensation. Each firefighter drank exactly 1 liter of fluid during a 60-minute recovery period, allowing researchers to compare how each drink affected hydration, recovery and physical performance.

• The firefighters who drank electrolyte beverages recovered fluid losses more effectively — Researchers measured body weight before exercise, immediately afterward and throughout recovery. Because sweat loss causes a measurable drop in body weight, regaining that weight is a practical way to evaluate rehydration.

In this small trial, the two electrolyte groups rehydrated at higher rates than the water group, suggesting that replacing electrolytes helped the body restore fluid balance more efficiently. If you exercise hard, work outdoors or sweat heavily in hot weather, this finding suggests that simply drinking more water isn’t always the fastest route back to full hydration.

• Hydration markers throughout the body consistently favored electrolyte drinks — The researchers examined saliva, blood and urine markers to determine how well participants recovered. Salivary osmolality, a measurement of how concentrated body fluids become, improved more in the electrolyte groups than in the water group. Urinary sodium levels also remained higher among participants consuming electrolyte beverages, indicating better retention of the minerals lost through sweat.

At the same time, urine color and other hydration measurements pointed toward superior fluid restoration among those receiving electrolyte drinks. Multiple measurements reached the same conclusion from different angles: the body handled and retained fluid better when electrolytes were included.

• Water drinkers stayed thirstier and recovered more slowly — Participants who drank plain water consistently reported greater thirst throughout the entire recovery period than those who consumed electrolyte beverages. By the end of the hour-long recovery session, thirst ratings remained significantly higher in the water group. Researchers also found that lactate clearance was slower among water drinkers.

Lactate is a byproduct that accumulates during intense exertion. Faster clearance generally indicates that the body is recovering from hard work more efficiently. Electrolyte drinks not only helped participants feel better hydrated but also helped their bodies bounce back faster after strenuous activity.

• The body’s fluid-retention system explains much of the difference — Sodium plays a central role in regulating fluid balance.

When you sweat heavily, you lose both water and sodium. Replacing water without replacing sodium reduces your body’s ability to hold onto that fluid. As the researchers explained, electrolyte-containing drinks help “enhance fluid absorption, reduce diuresis, and support plasma volume restoration.”

Diuresis simply means increased urine production. Electrolyte beverages helped participants keep more of the fluid they consumed instead of quickly losing it through urine. This improved fluid retention supports circulation, temperature regulation and recovery after intense physical stress.

• Menthol offered an unexpected performance benefit — While the menthol-enhanced drink didn’t improve hydration beyond the standard electrolyte beverage, it produced a unique result. Firefighters who consumed the menthol drink maintained their jump performance after recovery, while the water and standard electrolyte groups experienced declines.

Researchers believe menthol activates cold-sensing receptors in the mouth and throat, creating a cooling sensation even though body temperature doesn’t actually decrease.

That perception appears to reduce feelings of heat stress and helps preserve explosive physical performance. One caution comes with that: because menthol cools the sensation without lowering core temperature, it can leave you feeling safer than you are. If you lean on it through repeated bouts in heat, keep watching the objective signs of heat strain rather than how cool your mouth feels.

For anyone facing repeated bouts of intense activity in hot conditions, the findings suggest that recovery depends on more than replacing water alone. The right combination of fluids and electrolytes gives your body a better chance to restore balance and maintain performance when it matters most.

Because the trial enrolled only male firefighters, the results apply most directly to men doing heavy work in heat; women’s sweat-sodium losses and rehydration responses can differ, so individual adjustment matters.

*These findings are from research conducted in clinical settings. Results may not apply to all individuals.

Replace What Sweat Takes Away

The real problem isn’t water loss alone. When you sweat heavily, you lose fluids, sodium, potassium and other electrolytes that help your cells, muscles and nerves function properly. If you only replace the water while ignoring those losses, recovery becomes less efficient. Focus first on restoring the minerals and energy your body actually used during exertion instead of simply drinking large amounts of plain water.

1. Match your recovery drink to the amount you sweat — If you finish a long workout, spend hours outside in hot weather or perform physically demanding work, think beyond water alone. Your body loses both fluid and electrolytes through sweat. A carbohydrate-electrolyte drink helps replace those losses and supports faster restoration of fluid balance. The harder and longer you sweat, the more important electrolyte replacement becomes.

For daily hydration, focus on foods and beverages that naturally provide both fluids and minerals. Ripe fruit, watermelon, coconut water, cooked vegetables, tea with honey and raw milk provide hydration support that plain water alone does not.

If you sweat heavily and need larger amounts of fluid, adding a small pinch of a natural, unprocessed salt such as Himalayan pink salt, Celtic sea salt or Mediterranean sea salt to filtered water helps replace some of what sweat removes. A splash of orange juice or lemon improves flavor while providing additional minerals and carbohydrates that support fluid absorption.

2. Include sodium instead of avoiding it after heavy sweating — Many people spend all day trying to limit sodium, then continue avoiding it after losing large amounts through sweat. That approach works against recovery. Sodium helps your body retain the fluids you drink instead of rapidly excreting them. If you’re a runner, cyclist, outdoor worker, athlete or someone who exercises in the heat, replacing sodium after heavy sweating helps restore hydration more effectively.

Electrolyte concentrates are another option that some people use during hot weather or prolonged physical activity. If you choose one, look for products without artificial colors, sweeteners, or unnecessary additives. Alternating between electrolyte-enhanced fluids and pure filtered water helps maintain a healthier fluid and mineral balance than relying on water alone.

3. Add easy-to-digest carbohydrates after intense activity — The study found benefits from carbohydrate-electrolyte solutions, not electrolytes alone. Carbohydrates do more than refuel; glucose and sodium ride the same transporter across the gut wall, and water follows them in, so a little carbohydrate actually speeds how fast you absorb the fluid you drink. Focus on healthy carbohydrate sources that support cellular energy production.

Most adults need about 250 grams of carbohydrates daily, adjusted for activity level and gut health. Whole fruit, root vegetables and other well-tolerated carbohydrate sources are generally better choices than highly processed sports drinks. Avoid soda and commercial sports beverages loaded with high-fructose corn syrup, excessive sugar, artificial colors and additives that do little to support recovery.

4. Let your body tell you when hydration is on track — Instead of following a rigid rule about how many ounces of water to drink each day, pay attention to two of the most reliable hydration signals your body provides — thirst and urine characteristics. Thirst is your built-in hydration alarm.

When you sweat heavily, your body increases thirst to encourage you to replace lost fluids. Listening to that signal allows you to adjust your intake based on your activity level, body size, environment and sweat losses.

Your urine also offers valuable feedback. Pale straw-colored or light-yellow urine generally indicates good hydration, while dark yellow or amber urine suggests you need more fluids. Frequency matters too. Many well-hydrated people urinate around seven to eight times a day, though normal frequency varies from person to person.

If you’re making fewer trips to the bathroom or producing only small amounts of urine, your fluid intake is likely falling short. Just as dehydration creates problems, overhydration creates its own risks.

Drinking excessive amounts of water without replacing electrolytes dilutes sodium levels in the blood. When sodium falls too low, fluid moves into cells, including brain cells, which can lead to headaches, nausea, vomiting, confusion, drowsiness and, in severe cases, dangerous swelling inside the skull. The goal isn’t to drink as much water as possible. The goal is to maintain the right balance of fluids and electrolytes.

5. Build a stronger foundation for heat tolerance — Hydration starts long before you begin sweating. Daily movement, regular sun exposure, good sleep, adequate carbohydrates and proper mineral intake all support cellular energy production and improve your body’s ability to handle heat stress.

If you regularly exercise outdoors or work in hot environments, maintaining strong metabolic health reduces the strain that dehydration places on your body and improves your ability to recover from repeated bouts of exertion.

Another often-overlooked aspect of hydration is getting water into your cells. One way to support this process is by increasing your intake of structured water, sometimes called exclusion zone (EZ) water. This is the kind of water found inside your body’s cells. The idea is that drawing more of this gel-like water into your cells may support hydration from the inside. One of the simplest ways of getting this type of water into your body is to eat more well-cooked leafy greens.

You can also structure the water already inside your body by exposing your bare skin to near-infrared and ultraviolet (UV) radiation, i.e., sunlight, on a regular basis. At the same time, focus on maintaining a healthy sodium-to-potassium balance by emphasizing whole foods and minimizing processed foods, which tend to be loaded with sodium while providing very little potassium.

FAQs About Rehydration After Heavy Sweating

Q: Is plain water enough to rehydrate after heavy sweating?
A: Not always. When you sweat heavily, you lose both water and electrolytes such as sodium and potassium. The study found that firefighters who consumed carbohydrate-electrolyte drinks recovered hydration more effectively than those who drank plain water alone. Water helps replace lost fluid, but electrolytes help your body retain and use that fluid more efficiently.

Q: What are the best signs that I’m properly hydrated?
A: Two of the most useful indicators are thirst and urine characteristics. If your thirst is satisfied, your urine is pale yellow or straw colored, and you urinate about seven to eight times per day, your hydration status is generally on track. Dark urine, infrequent urination and persistent thirst suggest you need more fluids and electrolytes.

Q: Why are electrolytes so important after exercise or heat exposure?
A: Electrolytes regulate fluid balance, muscle contractions and nerve signaling. Sodium is especially important because it helps your body hold onto the fluids you drink instead of rapidly excreting them. Replacing electrolytes after heavy sweating supports faster recovery and helps restore normal fluid balance.

Q: Is it possible to drink too much water?
A: Yes. Drinking excessive amounts of water without replacing electrolytes can dilute sodium levels in your blood, a condition known as water intoxication. Symptoms include headaches, nausea, vomiting, confusion, drowsiness and, in severe cases, dangerous swelling in the brain. The goal is balanced hydration, not simply drinking as much water as possible.

Q: What foods and beverages support hydration better than plain water?
A: Foods and drinks that provide both fluids and minerals tend to support hydration more effectively. Good choices include ripe fruit, watermelon, coconut water, cooked vegetables, tea with honey, raw milk and electrolyte-enhanced beverages when sweat losses are high. These options provide water along with minerals and carbohydrates that help your body absorb and retain fluids.

Arthritis is a leading cause of chronic pain and disability, and more than 40% of affected adults have difficulty with daily activities. Learn more.

Health is shaped by more than the absence of disease. It reflects how your body performs each day, how effectively it repairs and recovers, and how well daily habits nourish its needs. In many ways, modern life often undermines these foundations. Holistic healing responds to this reality by addressing the whole picture — the physical, mental, and environmental influences that determine long-term well-being.

Dr. Leigh Erin Connealy, founder of the Cancer Center for Healing and the Center for New Medicine in Irvine, California, and a physician with more than 30 years of experience in integrative medicine, explored these principles in an interview with Brittany and Anthony Xavier on “The Long Game.” In the featured video above, she shared her perspectives on prevention, longevity, and practical measures that support lasting health.1

The Worsening State of Health in the US

The United States faces a deepening health crisis despite investing more in medical care per person than any other nation. By almost every measure of population health — from life expectancy to rates of chronic disease and mental illness — the trend lines are moving in the wrong direction.2

• Poor global ranking despite high spending — According to Connealy, the U.S. ranked 69th in global healthcare performance in 2024, a position that reflects an overall decline in outcomes even as technology and treatment capabilities advance. Life expectancy has fallen for three consecutive years, underscoring the scale and persistence of the problem.

• This decline is not limited to older adults — Chronic conditions are emerging earlier in life. Connealy notes that autism in California is now diagnosed in one out of every 22 children, while in other states the rate is one in 35. Diabetes affects one in three children, a condition once considered rare in this age group. By the time they reach elementary school, 60% of young kids have at least one chronic illness.

• Mental health in young people is also deteriorating — Teenagers are now experiencing the highest recorded rates of anxiety and depression, and suicide has become a leading cause of death in this age group. Emotional health is inseparably linked to physical health, and the decline in both is creating a generation at greater risk for lifelong health struggles.

Cancer Is Striking Younger — Early Detection Must Go Beyond Standard Tests

Cancer develops silently over many years before it is formally diagnosed, progressing quietly without obvious symptoms. By the time most cancers are found, they have been growing, changing, and interacting with the body’s systems for a significant period.3

• Rising rates in younger adults — Between 1990 and 2019, there has been an 80% increase in cancer cases. Connealy notes that many of her new patients are in their 20s, 30s, and early 40s. These include advanced-stage diagnoses, such as Stage 4 colon cancer, which were once considered rare in these age groups. The shift challenges the long-standing view of cancer as a disease that primarily affects older individuals.

• Addressing cancer begins long before the moment of diagnosis — According to Connealy, she looks at the full span of a patient’s life in the years leading up to their illness to assemble a complete picture of the patient’s physical and environmental landscape during the period in which cancer is most likely to have begun. As she explains:

“There are some things I go through when I see a patient. I go back from inception to where they are right now, and everything that’s happened to them, meaning not just how they sleep, the water they drink, the food they eat, the exercise they do or don’t do, their mouth, and their stress over the last 8 to 10 years. So, I know everything about them. So, I’m trying to figure out all the things that contributed to the development because nothing is just one thing.”4

• Comprehensive early detection strategy — To identify cancer as early as possible and understand the factors influencing its development, Connealy uses a range of advanced diagnostic tools. These methods go beyond standard protocols and are selected to provide a comprehensive view of a patient’s health from multiple angles, including:5

◦ Advanced blood testing — Measures inflammation, hormone balance, nutrient levels, and other internal markers that indicate cancer risk or progression.
◦ Circulating tumor cell testing — Detects cancer activity in the blood before tumors become visible, using specialized international labs.
◦ Whole-body MRI — Scans for solid tumors and abnormalities without radiation exposure, providing a broad view of the body.
◦ Thermography and ultrasound — Identifies abnormal vascular patterns and tissue changes, especially useful for dense breast tissue.
◦ Nutritional and toxic load analysis — Evaluates nutrient status and toxic elements inside cells to identify imbalances that may influence cancer risk.
◦ Energy and frequency assessments — Uses noninvasive scanning to detect disruptions in the body’s electrical and energetic systems.

• Risk-specific screening is another hallmark of her approach — Testing recommendations are tailored based on a patient’s genetics, family history, and existing conditions. The intention is to apply the most appropriate and least invasive methods for each individual’s risk profile.

By combining a detailed life history, advanced laboratory and imaging technologies, and personalized screening protocols, Connealy builds a multifaceted view of each patient’s cancer risk and current health status. This thorough and individualized approach is designed to both detect disease earlier and provide the necessary information for developing a targeted, patient-specific management plan.

Integrative Therapies for Cancer Care and Prevention

In the interview, Connealy outlines a prevention and treatment approach that combines nutritional, detoxification, oxygenation, and other advanced therapies. Each strategy is tailored to the individual and designed to strengthen the body’s defenses, remove harmful influences, and create an internal environment less favorable to disease.6

• Personalized nutrition plans — Connealy emphasizes the role of food as a foundation for both cancer prevention and supportive care during treatment. In the interview, she stressed the importance of creating daily conditions that promote recovery and resilience, starting with diet.

“You need to really think about your food. You need to eat nutrient-dense food. And really, you eat like your ancestors ate,” she noted. She advises avoiding harmful fats such as seed oils, eliminating refined sugar, and choosing nutrient-dense options like high-quality protein, organic fruits and vegetables, and raw dairy from reliable sources.

• Targeted supplementation — Supplement choices follow what shows up in labs and history. Intravenous vitamin C is at the center of her protocol, used daily and in higher doses when needed. She recommends camu camu as a valuable whole-food source of this nutrient, particularly suited for younger individuals. Connealy also discusses progesterone as part of a presurgical protocol for women:

“Like a woman who’s going to have breast surgery, for example, the higher your progesterone, the better outcome you have for the surgery … If they’re young, you want them to do it in their luteal phase, which is their peak time before their menstrual cycle.”7

Learn more about how to supplement with progesterone in “What You Need to Know About Estrogen and Serotonin.”

• Detoxification therapies — Reducing your body’s toxic burden supports immunity and mitochondrial function. Connealy suggests simple at-home practices such as Epsom salt and baking soda baths, sometimes combined with clay, to encourage relaxation and assist detoxification.

She also recommends using an infrared sauna when available. If you’ve been following my work, you know I advocate for this as well — learn more in “Your Complete Guide to Detoxing Heavy Metals Naturally and Boosting Vitality.”

• Oxygen-based treatments — Connealy uses ozone to raise tissue oxygen delivery and reduce microbial stress, and incorporates hyperbaric oxygen therapy where appropriate to increase dissolved oxygen in plasma. These methods support energy production and recovery while other parts of the plan address nutrition, toxins, and infections.

• Physical and biophysical therapies — She also shares that she uses pulsed electromagnetic field (PEMF) therapy to stimulate cellular repair and promote energy production. Moreover, she uses intravascular laser therapy with different wavelengths to influence mitochondrial activity and blood properties from within the vasculature, and full-body red-light beds for broad photobiomodulation.

Building Lifelong Wellness at Home Through Daily Lifestyle Habits

Daily decision-making is a central driver of long-term health. Connealy describes self-care as a continuous process rather than an occasional effort, and she links preventive strategies to the years before illness develops, extending even to the period before conception.9

• Building a strong health foundation before pregnancy — Optimizing the health of both parents prior to conception influences the health of future children. Beyond that stage, she advises patients to take an active role in their medical decisions, ask questions, and work with practitioners who tailor recommendations to each individual’s history and needs.

• Mental and emotional habits as part of healing — Emotional well-being is just as important as physical health. Thus, mindset practices are essential in both prevention and recovery plans. Affirmations before sleep help reinforce constructive beliefs at a subconscious level, while beginning the day with gratitude and intention sets a stable tone. Introducing your children to daily meditation for 10 to 15 minutes also helps calm their minds, improve focus, and support emotional regulation.

• Excellence over perfectionism — Connealy advises aiming for steady, sustainable progress rather than holding to rigid standards. Having a clear sense of purpose, personal values, and inner stability helps you maintain perspective and guide your decision-making during challenging times.

• Modeling healthy habits for children — Lead your children by example when teaching healthy behaviors. Explaining the reasons behind such choices helps them understand their value and encourages them to make informed decisions on their own.

• Prioritizing daily movement and time outdoors — Regular exposure to natural light, fresh air, and physical activity helps regulate sleep, elevate mood, and support physical development. Making these elements part of the family’s daily rhythm turns them into reliable, lasting habits.

By making these practices a consistent part of daily life, you create conditions where health is continually supported.

Frequently Asked Questions (FAQs) About Holistic Cancer Prevention and Wellness

Q: How can I tell if I’m at risk for cancer before I have symptoms?
A: Cancer often develops silently for years before diagnosis. Dr. Connealy advises getting advanced screening that looks beyond standard tests. Options include circulating tumor cell testing, whole-body MRI, thermography, and specialized blood panels that check for inflammation, hormone balance, nutrient status, and toxin exposure.

Q: Can nutrition really make a difference in cancer prevention and recovery?
A: Yes. Nutrient-dense, whole foods strengthen the immune system, support repair processes, and improve energy metabolism. Avoiding harmful fats like seed oils, eliminating refined sugar, and choosing high-quality protein, organic produce, and raw dairy from trusted sources are key steps.

Q: How do detox therapies like infrared sauna and Epsom salt baths help with healing?
A: These therapies promote relaxation, improve circulation, and support the removal of toxins through sweat and skin pathways. Adding clay to baths may further assist in binding impurities.

Q: What lifestyle changes should I make before getting pregnant to give my child the best start?
A: Improving nutrition, reducing toxin exposure, balancing hormones, and managing stress before conception benefits both parents and sets a healthier foundation for the child.

Q: What’s the best way to get my children involved in healthy routines?
A: Leading by example is most effective — modeling good eating habits, regular physical activity, and mindfulness. Explaining the reasons behind these habits helps children value and maintain them.

Most people think about smog, traffic exhaust, or industrial fumes when they hear the word “air pollution.” But harmful exposures don’t always come from outdoors. Sometimes, they come from inside your house in the form of ultrafine particles (UFPs). Measuring less than 100 nanometers in diameter, these invisible particles stay suspended in indoor air and pass easily into your lungs when you breathe, bypassing the filtering mechanisms that catch larger particles.1

Surprisingly, small electric appliances — the kind you use daily, often in enclosed rooms and close to your face — are emerging as a significant source of UFPs. A team of researchers at Pusan National University (PNU), South Korea, has investigated this overlooked source of emissions, shedding light on what might be quietly building up in the air around you during ordinary routines like preparing meals or getting ready for the day.2

The deeper implications of how UFPs behave in human tissue — including their movement, persistence, and interaction with cellular systems — are explored in detail in my upcoming book, “Microplastics Cure: Total Body Cleanse,” which comes out soon. It also outlines the Pollution Solution (PS), a comprehensive strategy to help the body eliminate these invisible pollutants efficiently.

How Common Appliances Release Heavy Metal-Containing UFPs

The featured study, published in the Journal of Hazardous Materials, examined appliances that combine two features common in modern homes — internal heating elements and electric motors that rely on physical contact to operate. Researchers tested hair dryers, air fryers, and toasters widely sold in South Korea, measuring particle emissions using real-time aerosol instruments while the appliances were running.3

• Researchers targeted appliance features known to generate airborne particles during routine use — Heating coils and brushed direct current motors were selected based on prior aerosol science showing both release particles under normal operating conditions. Heating coils reach high temperatures through electrical resistance, a process that promotes evaporation and condensation of metal components.

Brushed motors rely on constant physical contact between brushes and rotating parts, producing friction and electrical sparking that wear down metal surfaces. These processes occur during everyday use and do not require malfunction or misuse.

• Emission patterns differed sharply depending on appliance design and particle size range — Hair dryers equipped with brushed motors produced large numbers of UFPs, typically smaller than 25 nanometers.

In contrast, air fryers and toasters relying mainly on heating coils generated slightly larger UFPs, generally between 25 and 100 nanometers. Although larger, these particles still behave very differently from visible dust or soot and remain readily inhalable.

• Brushless motor designs released substantially fewer UFPs — When researchers compared brushed hair dryers to brushless models, emissions from brushless designs were at least 1.4 times lower under similar operating conditions. This difference helped isolate the role of mechanical contact and sparking in particle generation and showed that design choices within the same appliance category meaningfully influence indoor air pollution.

• Chemical analysis revealed heavy metals originating from appliance components — Many of the collected UFPs contained metals commonly used in appliance construction. Copper appeared frequently, consistent with its role in motor windings and electrical contacts. Iron and aluminum were also detected, reflecting structural components and heating elements.

Silver and titanium, both used in certain coatings and alloys for heat resistance and durability, were identified as well. These metals were present as ultrafine airborne particles rather than bulk fragments, making them capable of entering the respiratory system during normal appliance use.

• Higher temperatures and typical usage patterns increased exposure potential — Particle emissions increased at higher heat settings, which fits with how metals heat up, wear down, and release material over time. Real-world exposure also depends on how people actually use these appliances day to day.

Hair dryers often operate close to the face and upper body, while cooking appliances are frequently used in confined kitchen spaces with limited ventilation. Repeated daily use under these conditions increases the likelihood that particles remain suspended long enough to be inhaled.

• UFPs preferentially deposited deep in the lungs — Using a model that tracks how particles move through the airways, researchers found that most UFPs traveled deep into the lungs and settled in the alveoli, the tiny air sacs where oxygen enters the bloodstream.

At this size, the movement of the particles was driven by diffusion rather than gravity, which lets the smallest particles lodge more easily in delicate lung tissue than larger ones, even when standard air quality readings suggest exposure is low.

• Children experienced a higher internal lung burden than adults — The modeling also revealed that children ended up with more particles settling in their lungs relative to lung size, mainly because their airways are smaller and the way they breathe differs from adults.

Even after accounting for body weight, children still carried a higher particle load in lung tissue. This means the same indoor air can lead to a much higher internal exposure for children, especially in homes where these appliances are used several times a day.

• The findings point to broader design and policy implications — By showing how routine household devices release metal-containing UFPs under normal use, the research highlights gaps in how indoor air risks are currently assessed and managed.

“Our study emphasizes the need for emission-aware electric appliance design and age-specific indoor air quality guidelines. In the long term, reducing UFP emissions from everyday devices will contribute to healthier indoor environments and lower chronic exposure risks, particularly for young children, than current status.

Moreover, this framework can be extended to other consumer products, guiding future innovations toward human health protection,” said Changhyuk Kim, Ph.D., lead author and professor at PNU.4

Systemic Health Consequences of Heavy Metal Exposure

Heavy metals cause harm through repeated, low-level exposure that gradually interferes with normal biological function. When these metals are attached to UFPs, they can move deep into the body, extending their effects well beyond the lungs and contributing to health problems such as:5,6,7,8

• Respiratory inflammation and reduced lung function — UFPs deposited deep in your lungs can trigger inflammation of airways and lung tissue. Persistent inflammatory responses contribute to conditions like asthma, chronic bronchitis, and many cases of reduced lung capacity.

• Oxidative stress and cellular damage — Once inside the body, heavy metals generate reactive oxygen species (ROS). ROS are highly reactive molecules that damage cellular components, including lipids, proteins, and DNA. This oxidative burden overwhelms your antioxidant defenses and contributes to chronic inflammatory signaling and tissue injury.

• Cardiovascular stress and dysfunction — UFPs and heavy metals in circulating blood are associated with changes in vascular function, including endothelial dysfunction (the lining of your blood vessels). These changes are linked to increased blood pressure and a greater risk of ischemic heart disease, heart rhythm abnormalities, and vascular inflammation that underlies many cardiovascular conditions.

• Neurotoxicity and brain effects — Certain metals, such as copper, can reach the brain by crossing the blood-brain barrier. Within nervous system tissue, they promote neuroinflammation and oxidative stress, which are associated with impaired motor function, particularly in children, as well as increased susceptibility to neurodegenerative processes over time.

• Disruption of cellular regulation and repair — Many heavy metals disrupt key biochemical pathways that regulate cell growth, survival, and programmed cell death (apoptosis). For example, metals can block antioxidant defenses and disrupt key proteins inside cells, weakening normal repair processes and increasing the risk of abnormal cell behavior.

• Increased carcinogenic risk — Persistent oxidative stress and DNA damage from heavy metal exposure drive mutations that play a direct role in cancer development. Chronic inflammation and interference with normal cell division add to this risk, creating conditions that allow damaged cells to survive and multiply over time.

• Impaired development — Because children’s organs are still developing and their detox systems are not fully mature, they clear inhaled metals less efficiently. When exposure occurs during key stages of lung and brain development, more particles accumulate relative to body size. This higher internal load increases the likelihood that inhaled metals affect breathing, circulation, and long-term health.

• Metabolic and autonomic disruption — Evidence links particle exposure to insulin resistance and metabolic dysregulation. Inhaled particles also interact with autonomic nervous system pathways, which can influence heart rate variability and stress responses, further contributing to chronic disease risk.

How to Lower Your Heavy Metal Burden Safely and Effectively

If these appliances are part of your daily routine, it’s essential to support your body’s ability to clear the heavy metals they release. Here are some practical strategies to help you reduce your toxic load:

1. Support liver function with adequate choline intake — Your liver is the primary organ responsible for processing heavy metals and exporting them into bile so they can be eliminated through the intestines. When choline intake is insufficient, fat accumulates in the liver, impairing this detox function and slowing metal clearance.

Ensuring adequate choline, particularly from foods like pasture-raised eggs or from highly bioavailable forms such as citicoline, helps maintain normal bile flow and preserves your liver’s ability to remove metals efficiently.9

2. Bind metals in the gastrointestinal tract — After the liver transfers heavy metals into bile, they enter the intestines, where they need to be bound to prevent reabsorption back into circulation. Binders such as charcoal and calcium bentonite clay capture metals and other toxins in the gut, allowing them to be excreted. This step reduces the overall time heavy metals remain in your body.

3. Optimize glutathione availability — Glutathione acts as your body’s primary intracellular detox molecule, binding heavy metals and neutralizing the oxidative stress they generate. Chronic toxic exposure increases glutathione demand, which can outpace production.10

Supporting your body’s glutathione synthesis with precursors like N-acetylcysteine (NAC) or using liposomal or sublingual glutathione improves circulating levels and enhances your cells’ capacity to safely neutralize and eliminate metals.

4. Activate Nrf2-driven detox pathways — Nrf2 is a transcription factor that switches on genes involved in antioxidant defense and toxin removal.11 Compounds such as R-lipoic acid, sulfur-containing compounds from cruciferous vegetables and alliums, and certain polyphenols increase Nrf2 activity, strengthening your cells’ ability to manage oxidative stress while supporting long-term detox resilience.

5. Incorporate high-intensity training into your routine — Performing high-intensity exercise for up to 75 minutes per week helps the body clear heavy metals more effectively. I don’t recommend any more than that, though, as research shows you start losing longevity benefits when you go beyond 75 minutes a week.12

6. Support detox with sauna — Like exercise, sauna use supports heavy metal detox by increasing sweat production. If you are new to saunas, limit sessions to 20 to 30 minutes to avoid overheating and dehydration. Drink water before you go in and rehydrate immediately afterward. Adding electrolytes to your drink helps replace minerals lost through sweat and supports fluid balance during recovery.

For a synergistic effect, alternate sweat-inducing exercise and sauna sessions during the week, or add a short sauna session right after a workout. Pay close attention to how your body reacts to increased sweating from exercise and sauna use. Watch for signs of dehydration, such as dizziness, weakness, or unusual fatigue, and scale back when needed.

Pay close attention to how your body responds and adjust detox steps slowly rather than all at once, since steady progress places less strain on your system. Letting symptoms guide the pace helps heavy metals move out efficiently while preserving metabolic stability, energy levels, and long-term health.

5 Practical Strategies to Reduce Your Exposure to Heavy Metals in UFPs

Now that you understand how the body clears heavy metals, it becomes just as important to reduce how much you take in to begin with, so detoxification does not have to carry the full burden. Lowering exposure at the source helps prevent repeated accumulation and makes long-term management far more sustainable. Here are practical steps you can take to minimize the heavy metal-containing ultrafine material you’re exposed to during everyday appliance use:

1. Choose appliances with brushless motor designs — When replacing or upgrading household appliances, selecting models that use brushless motors significantly reduces UFP emissions during normal operation. Brushless designs eliminate the mechanical friction and electrical sparking present in brushed motors, which directly lowers the amount of metal-containing particles released into the surrounding air.13

2. Use lower heat settings whenever possible — Since higher operating temperatures increase particle release from heating, using the lowest effective heat setting reduces the number of particles emitted while still allowing the appliance to perform its intended function, particularly for cooking and personal care devices.14

3. Use particle-emitting appliances wisely — Scheduling routine tasks using these appliances for times when living spaces are unoccupied by children and limit how long they run to reduce total particle release throughout the day.
Turning devices off as soon as tasks are finished avoids unnecessary emissions that add to indoor air pollution. Running multiple heat- or motor-driven appliances at the same time can also overwhelm ventilation and filtration systems, so staggering appliance use helps keep indoor concentrations within safer, more manageable ranges.

4. Ventilate rooms during and after appliance use — Opening windows or running exhaust fans creates airflow that carries UFPs out of enclosed spaces. That said, ventilation does not mean opening windows when outdoor air quality is poor, since this can bring pollutants indoors. Instead, open windows for at least 15 minutes a day when outdoor conditions are favorable, even in colder weather, to refresh your indoor air.

5. Use high-quality air filtration systems — Your home should be a protective space, not another source of pollutants. I suggest investing in air purifiers equipped with high-efficiency particulate air (HEPA) filters to remove UFPs and harmful pollutants from the air.

Keep windows and doors closed during peak pollution periods, such as rush hour or wildfire events, and run purifiers continuously. Replace filters on schedule so the system keeps working as intended and indoor air stays consistently clean.

While exposure reduction is essential, it’s only one side of the equation. We already have the solution — what I call the Pollution Solution (PS). This full-spectrum detox strategy is detailed in “Microplastics Cure: Total Body Cleanse,” which will be coming out soon.

Frequently Asked Questions (FAQs) About Heavy Metals in UFPs

Q: How am I exposed to UFPs from household appliances?
A: You are exposed when appliances that use heating elements or certain motor designs release UFPs into indoor air. Because these devices are often used in enclosed spaces and close to your breathing zone, the particles they emit can be inhaled before ventilation or filtration removes them.

Q: What makes heating coils and brushed motors a problem?
A: Heating coils reach high temperatures that can release metal-containing particles, while brushed motors generate friction and electrical sparking that wear down metal components. These processes occur during routine use and do not require appliance malfunction, which makes exposure more frequent and predictable.

Q: Why are ultrafine particles more concerning than regular household dust?
A: Ultrafine particles are small enough to bypass the body’s usual airway defenses and travel deep into your lungs. Once inhaled, they behave differently than larger particles, remaining airborne longer and interacting more directly with lung tissue, which increases their biological impact even at low concentrations.

Q: Why are children more affected by these particles than adults?
A: Children inhale more air relative to their body size and have smaller airways, which leads to a higher proportion of inhaled particles settling in their lungs. Modeling data show that, even in the same indoor environment, a child’s lungs can accumulate a higher internal particle burden than an adult’s.

Q: Do air purifiers actually help with ultrafine particles?
A: Air purifiers equipped with HEPA filters can capture a large portion of ultrafine particles when used consistently. Running them during appliance use and afterward helps reduce background particle levels, especially in rooms with limited natural airflow.

Few things derail fitness progress faster than poor recovery. When workouts or competitions occur close together, what happens after exercise matters as much as the training itself. Performance in the next session hinges on how well recovery supports your body’s return to balance, not on motivation or willpower.

Once intense exercise ends, your body enters a fragile state. Muscle fuel runs nearly empty. Tissue damage triggers repair signals. Dehydration thickens your blood. What happens in the next few hours determines whether you wake up ready to train — or dragging.

Nutrition sits at the center of that process. A Sports Medicine review shows that post-exercise nutrition consistently influences how quickly strength, endurance, and focus return when recovery time is limited.1 Poor recovery nutrition allows fatigue to stack. Targeted recovery nutrition resets the system and preserves training momentum.

These findings explain why generic post-workout advice falls apart under real-world demands. To understand how recovery actually works, it helps to break down what this research uncovered and why specific strategies outperform others when the clock between sessions starts ticking.

Why Recovery Nutrition Decides Your Next Performance

The Sports Medicine study evaluated how post-exercise nutrition influences recovery and performance when the next workout or competition occurs within roughly two to 24 hours. The authors reviewed controlled human studies that examined carbohydrates, protein, fluids, electrolytes, and select supplements, focusing on real-world scenarios where recovery time is tight and performance matters most.

The studies summarized involved trained athletes and active adults exposed to endurance, high-intensity, and resistance-based exercise protocols designed to significantly deplete energy stores and fluids.

The researchers asked a practical question: which nutrition strategies actually help you perform better in the next session when fatigue, dehydration, and fuel depletion stack the odds against you. Many athletes, active adults, and recreational exercisers train again before full recovery occurs, which magnifies the impact of post-exercise nutrition choices on strength, endurance, coordination, and mental sharpness.

• Findings consistently favored targeted recovery nutrition — Across the evidence, individuals who consumed adequate carbohydrates, protein, and fluids after exercise showed faster restoration of physiological balance and stronger subsequent performance compared with those who delayed or under-consumed nutrients. Benefits were most relevant when the next session occurred within a day, which mirrors tournament play, double training days, and demanding work or fitness schedules.

• Carbohydrates emerged as the primary recovery driver — Consuming carbohydrates soon after exercise restored muscle glycogen faster than waiting, especially during the first two hours when muscles absorb glucose at a higher rate. Glycogen is the stored form of carbohydrate in muscle and liver, meaning the fuel your body relies on for repeated efforts.
Think of your muscles like a sponge that’s been wrung out. Immediately after exercise, that sponge is most absorbent — special glucose transporters move to the surface of muscle cells, creating a window when fuel replacement happens fastest. Wait too long, and the sponge stiffens.
Total carbohydrate intake mattered more than glycemic index. Consuming roughly 1 to 1.2 grams per kilogram of body weight per hour — about 70 to 85 grams for a 155-pound person — drove glycogen restoration regardless of whether carbohydrates came from fast- or slow-digesting sources. When carbohydrate intake was postponed by two hours, muscle glycogen levels remained lower several hours later, which translated into weaker performance the following day.

• Protein supported repair rather than fuel — Protein intake after exercise improves muscle repair and limits muscle protein breakdown, which preserves strength and power for subsequent sessions. Protein doesn’t replace glycogen, but it prepares muscle tissue to perform again under load. Consuming roughly 20 to 40 grams of high-quality protein after exercise supported recovery, with total daily protein intake playing a larger role than exact minute-by-minute timing.

How Protein, Fluids, and Timing Shape Recovery When Time Is Tight

With carbohydrate timing established, the research reveals how protein and fluids interact with that foundation — and where combining nutrients produces synergistic effects. Combining protein with carbohydrates helped in specific cases. When carbohydrate intake fell below optimal levels, adding protein improved recovery and led to small but meaningful performance gains in the next session.

• Hydration strongly influenced recovery quality — Studies reviewed showed that dehydration impaired glycogen restoration and muscle repair, while aggressive rehydration improved readiness for subsequent exercise. Replacing sweat losses requires more than drinking to thirst. The review explains that consuming fluids equal to about 125% to 150% of the weight lost during exercise improves fluid balance, especially after heavy sweating or heat exposure.

• Plain water exits your body quickly — Beverages containing electrolytes, carbohydrates, or protein are retained longer — meaning more of what you drink actually stays in your system to support coordination, endurance, and strength when you train again.

• Performance gains varied by recovery window. Benefits from carbohydrate-protein combinations, creatine, caffeine, or sodium bicarbonate appeared strongest when recovery periods were short and demands were high. Creatine increased glycogen storage over days rather than immediately, which matters if you train repeatedly across a week rather than within the same day.

• The biology behind recovery centered on fuel and balance. The paper explains that rapid carbohydrate intake restores muscle glycogen, protein intake shifts muscle from breakdown to repair, and fluids normalize blood volume and circulation. During intense exercise, your body breaks down muscle proteins faster than it builds them — like withdrawing more from a bank account than you deposit.
Protein intake reverses this balance, switching your muscles from demolition mode to construction mode. Intense exercise also produces acid buildup in muscles — that burning sensation you feel. Proper nutrition and hydration help clear this acid, restoring your muscles’ ability to contract forcefully.

• Your body’s uptake machinery works overtime immediately after exercise — Glucose transporters flood to muscle cell surfaces, and amino acid absorption accelerates. This heightened state explains why the first two hours offer a recovery advantage — your muscles are primed to receive fuel.

Recovery nutrition also sets the stage for sleep, when growth hormone peaks and tissue repair accelerates. Going to bed dehydrated or glycogen-depleted fragments sleep and undermines the recovery you’ve worked to support.

How to Recover Faster and Perform Better Next Time

If your workouts leave you drained the next day, the issue rarely sits in your training plan. The problem usually traces back to recovery. When fuel stays low, fluids stay depleted, and muscle tissue remains in a breakdown state, performance drops quickly. Address those root causes directly, and strength, energy, and coordination rebound.

1. Restore carbohydrate stores immediately after training — It’s important not to overdo intense exercise, as it often backfires. However, when training again within a day, the top priority is replacing glycogen, the stored fuel muscles rely on for strength and endurance. Muscles absorb glucose fastest in the first two hours after exercise. For most adults, this means roughly 1 to 1.2 grams of carbohydrates per kilogram of body weight per hour early in recovery.
Adequate carbohydrate intake directly improves energy levels, coordination, and performance in the next session.

2. Pair carbohydrates with enough protein to halt muscle breakdown — Intense exercise pushes muscle tissue into a breakdown state. Including protein after training shifts muscle toward repair and rebuilding. About 20 to 40 grams of high-quality protein after exercise improves recovery when sessions occur close together.2 This limits lingering soreness and preserves strength for the next workout.

3. Replace more fluid than you lost — Dehydration slows glycogen restoration, impairs muscle repair, and reduces performance. Effective sports recovery requires replacing roughly 125% to 150% of body weight lost during exercise, especially after heavy sweating. Weigh yourself before and after training without clothes. Every pound lost represents roughly 16 ounces of fluid to replace. For a two-pound loss, aim for 40 to 48 ounces over the next few hours.
Fluids that include electrolytes or nutrients, like coconut water or mineral-rich bone broth, stay in your body longer than plain water, which supports endurance, focus, and coordination in subsequent exercise. Choose recovery beverages with natural carbohydrate sources rather than artificial sweeteners or excessive refined sugars paired with synthetic additives.

4. Match recovery strategy to how soon your next session occurs — When recovery time is short, timing outweighs perfection. Rapid carbohydrate intake, adequate protein, and aggressive rehydration matter most. When recovery spans multiple days, consistency across meals and fluids becomes the dominant factor. Aligning recovery with training frequency prevents unnecessary fatigue and stalled progress.

5. Turn recovery into a repeatable system that reinforces progress — Recovery works best when treated as a structured routine rather than an afterthought. Rather than guessing each time, follow a simple post-workout protocol:

• Within 30 minutes of finishing — Consume 20 to 40 grams of protein (such as whey protein, grass fed yogurt, grass fed beef, or pastured eggs) along with 50 to 70 grams of carbohydrates (roughly two bananas and a slice of homemade sourdough bread, or a large bowl of rice). Pair this with 20 ounces of fluid containing electrolytes — coconut water, a pinch of salt in water with citrus, or a clean electrolyte drink.
• Within two hours — Eat a full balanced meal with additional carbohydrates to continue restocking glycogen stores.
• Before bed — Check your urine color. Pale yellow signals adequate hydration. Dark yellow means you need more fluids before sleep, when much of your tissue repair occurs.

Track how your energy, strength, and focus feel in your next session. Are you hitting the same weights? Maintaining your usual pace without dragging? Mentally sharp instead of foggy? When these markers improve consistently, your system is working.

FAQs About Nutritional Strategies to Improve Performance

Q: Why does recovery nutrition affect my next workout so much?
A: Recovery nutrition determines how quickly your body restores fuel, repairs muscle tissue, and rebalances fluids after exercise. When recovery time is short, poor nutrition allows fatigue to carry over, while targeted nutrition restores energy, coordination, and strength for the next session.

Q: What matters more after exercise — carbohydrates or protein?
A: Carbohydrates matter most for restoring energy, especially when you train again within 24 hours. Protein plays a supporting role by repairing muscle and limiting breakdown. Together, they help you show up stronger and less sore for your next workout.

Q: How soon after exercise does recovery nutrition matter?
A: The first two hours after exercise are especially important. During this window, muscles absorb fuel and amino acids more efficiently. Delaying recovery nutrition during this period slows energy restoration and increases next-day fatigue.

Q: Why isn’t drinking water alone enough for recovery?
A: Plain water doesn’t replace electrolytes or support fluid retention after heavy sweating. Fluids that contain electrolytes or nutrients stay in your body longer, which improves endurance, focus, coordination, and overall readiness for your next workout.

Q: How do I know if my recovery strategy is working?
A: The clearest signal is how you feel and perform in your next session. Better recovery shows up as steadier energy, improved coordination, less soreness, and stronger output. When those markers improve consistently, your recovery approach is doing its job.

Since starting the Forgotten Side of Medicine, I’ve received quite a few correspondences from readers asking me to write about constipation. This I believe, is reflective of how widespread but rarely discussed constipation is, especially as one becomes older1 (where it often becomes a primary concern of everyday life).

Likewise, the primary diagnosis for constipation is “chronic idiopathic constipation” (CIC). Idiopathic, for reference, means “no one knows why” which is remarkable given that existing studies find2 between 9% to 20% of adults (averaging at 14%) have CIC. This figure in turn, varies greatly by country:

In tandem, there is no clear consensus on how to treat CIC (e.g., if you review the treatment guidelines,3 you will see they vary greatly depending on which country they were made in). Likewise, the majority of patients do not even discuss their condition with their doctors:

“Overall, 4,702 participants had experienced constipation (24.0% met the Rome IV CIC criteria).4 Among all respondents with previous constipation, 37.6% discussed their symptoms with a clinician (primary care provider 87.6%, gastroenterologist 26.0%, and urgent care/emergency room physician 7.7%).

We found that the locus of control — the extent to which individuals believe they can control events that affect them — is associated with healthcare seeking for constipation. Namely, those with a lower locus of control (i.e., who believe symptoms are driven by others, chance, or fate) are more likely to consult with providers regarding their symptoms.

However, individuals experiencing this maladaptive cognition may be resistant to both undergoing indicated diagnostic testing and accepting and adhering to treatments, thereby undercutting treatment success and reducing patient satisfaction.”

Additionally, many who seek out medical help end up getting colonoscopy, a procedure which carries real risks and has no benefit here:

“Among those who sought care, 54% reported previous diagnostic testing.5 Colonoscopy was the most commonly performed test; 46% of health seekers specifically underwent the procedure to evaluate their constipation.

Although we did not ask the respondents about alarm features or have access to their medical records to confirm the ‘true’ indication for the procedure, this suggests potential overuse of endoscopy in the evaluation of constipation. This is an issue because the diagnostic yield of colonoscopy for constipation is limited.

Pepin and Ladabaum noted that in 234 individuals undergoing lower endoscopy solely for constipation, no cancers were found, and only 3% had advanced lesions. The American Society for Gastrointestinal Endoscopy states that colonoscopy should not be performed in the initial evaluation of constipated patients without alarm features or suspicion of organic disease.

The high usage of endoscopy and other tests seen in our study, in combination with the high prevalence of constipation, further reinforces the significant impact of constipation on population health and healthcare costs and emphasizes that efforts to reduce unnecessary testing are needed.”

In short, there is a surprising gap of knowledge in this area, which I believe is best demonstrated by how many times I’ve been asked to admit a patient to a hospital who was essentially just severely constipated.

Note: The current research shows constipation hospitalizes 92,000 Americans each year6 and results in 1.3 million visits to American emergency rooms,7 which again illustrates our society’s lack of knowledge in this area, especially as the rate of this is increasing (e.g., from 2006 to 2011, there was a 42 percent rise in ER visits for constipation).8

The Effects of Constipation

While it is relatively unlikely one will be hospitalized for constipation, the condition nonetheless has a significant effect on quality of life, as it is stressful to be unable to defecate when you attempt to and often quite uncomfortable once too much has built up inside you. Conversely, after a large bowel movement (especially if they’ve been constipated), individuals often feel much better and clear-headed.

Constipation frequently results in significant issues. Most commonly, we recognize its connection to the fact that the pressure created by strained bowel movements can lead to hemorrhoids, rectal prolapse, and anal fissures. However, it can also lead to less appreciated issues including:

• Dysbiosis within the gut microbiome. In many cases, the gut dysbiosis that leads to constipation results from foods not being fully digested. One of the most interesting things I learned is that SIBO often results from slowed bowel transit time, and practitioners who are most successful in treating SIBO focus on increasing peristalsis to facilitate the body eliminating the problematic bacteria.9

• Fatigue, headaches, abdominal pain, nausea, and vomiting.10

• Chronic constipation is linked to progressively more severe illnesses, including diverticulitis, kidney disease, gastric and colorectal cancer, ischemic colitis, and Parkinson’s disease.11

The Dangers of Laxatives

Since most constipation is labeled as “idiopathic” treatments are typically symptom based. Unfortunately, while laxatives are relatively benign if used occasionally, over time, they can impair the normal function of the GI tract and create a situation where one requires chronic laxative use.

Note: Clinicians have also reported instances where laxatives destroyed the normal functioning of the colon which then required part of the colon to be surgically removed.12

One of the most commonly used laxatives (MiraLAX) can create issues because a surprising number of people have sensitivities or allergies to polyethylene glycol. When individuals have delayed bowel transit time (anyone who is constipated), they are more likely to systemically absorb MiraLAX and experience toxicity from it.

As such, it is critical to identify the actual cause of constipation rather than just trying to perpetually treat the symptoms.

Conventional Causes of Constipation

When evaluating the root cause of constipation, it is critical never to forget that constipation can also be a symptom of a more serious illness.

For example, when a tumor grows in the colon, it progressively blocks transit through the colon, which in turn leads to the feces becoming narrower and narrower (along with abnormal weight loss, anemia, and rectal bleeding). Because of this, if you notice that it is gradually happening, it is worth getting a preliminary test to see if you may have cancer (there are simple and complex ways to test the stools for colon cancer).13

Note: Red meat (especially for those who do not eat it frequently) and beet juice can also make the stools turn red.

Other diseases that can frequently cause constipation include:

• Hypothyroidism — One of the common symptoms of hypothyroidism (beyond hair loss, coldness, fatigue, and weight gain) is delayed bowel transit time. As such, if you are constipated, you need to consider if you are hypothyroid.

• Hyperparathyroidism — This is a surprisingly common but unrecognized condition which can make individuals feel quite ill (e.g., it can cause pain throughout the body, cognitive issues, arrhythmias, kidney stones, unexpected fractures, and gastrointestinal issues).

• Anxiety or depression — Many report stress and anxiety causes constipation, and extensive data supports this.14 For example, a large study15 found anxiety was significantly more common in constipated patients, another found 65% of constipated patients had psychiatric conditions — most frequently anxiety or depression.16

Proposed mechanisms include brain-gut axis dysfunction, increased pelvic floor muscle tension due to anxiety, altered gut microbiota in anxiety, and hormonal pathways affected by stress — and my leading hypothesis — sympathetic activation directly reducing bowel transit.17 Because of this, mind-body practices that relax the body can sometimes be quite helpful, as is psychological support.

Note: The natural treatments for anxiety are discussed here and those for depression here.

Additionally, many medications, particularly opioids, can cause constipation, with potential offenders also including antacids, anticholinergics, antidepressants, antihistamines, antipsychotics, calcium channel blockers, certain blood pressure medications, and NSAIDs. Because of this, if you develop constipation after starting a new prescription, it is always important to see if that drug is linked to impaired bowel movements.

Note: Iron and calcium supplements can sometimes cause constipation (e.g., iron supplements cause constipation for approximately 10% of users18).

Other Causes of Constipation

Unfortunately, in most cases, the cause of constipation remains unknown, and typically the advice given is to “eat more fiber,” which while sometimes helpful often is not. Additionally, in some cases, the benefits of fiber are not due to their stool bulking activity but rather that they directly stimulate peristalsis.

Presently, I believe there are a few major contributors to the epidemic of constipation we face that are largely overlooked.

• Dietary causes:

◦ Dairy consumption (particularly in children) — which has been shown in many studies (e.g., a randomized trial found that 71.4% of children with chronic constipation not responding to laxatives significantly improved within 4 weeks of stopping dairy, whereas only 11.4% of the control group,19 with similar results seen in this blinded crossover trial).20

Note: While this is often attributed to food allergies, it may also be due to the opioid-like substances in dairy (e.g., beta-casomorphin), as individuals often improve on milk lacking these substances, and severe constipation has been found to be reversed by naloxone (an opioid blocker).21

Likewise, gluten contains opioid-like peptides (gluten exorphins)22 which have been shown to slow bowel transit time23 and cause constipation.24 Lastly, the variable sensitivity to these compounds (and being predisposed to constipation)25 may be a result of genetic susceptibility (e.g., OPRM1 A118G polymorphisms have been repeatedly shown to influence sensitivity to opioids).26

◦ Poor diet and food triggers of constipation. Beyond dairy, we find the constipation-causing agents often vary person to person, with the most commonly reported (ordered by frequency) being cow dairy, gluten, goat’s milk, beef (red meat), legumes, eggs, fried foods, rice (white), bananas (unripe), chocolate, caffeine (excess), alcohol (excess), tea (excess).

Additionally, refined grains frequently lack the fiber needed to facilitate healthy bowel movements, and many readers have found using freshly milled whole grain flour (e.g., wheat, within 24 hours of milling) cured their constipation.

Note: Within Chinese medicine, there is an entire diagnostic model based on looking at the characteristics of one’s stools.27 I have often found it to be extremely useful, and I often monitor my own stools to assess how my body is handling my current diet.

• Nutrition and hydration — In addition to certain foods causing constipation, a lack of critical substances can as well.

For example, chronic dehydration is widely recognized to be a cause of constipation (due to it drying out the stools and making them harder to push through). Additionally, I strongly suspect dehydration causes peristalsis (bowel motion) to shut down, as I’ve seen numerous cases where “frozen bowels” rapidly softened and resumed their normal function once the individuals received either a saline infusion or a zeta potential restoring treatment.

Likewise, ultraviolet blood irradiation has been repeatedly observed to rapidly restore bowel function. Likewise, mineral deficiencies (primarily magnesium) and in some cases potassium can sometimes cause constipation.28

• Gastrointestinal dysfunction — As we rely on the gastrointestinal tract to push food along (through a process known as peristalsis), constipation can also signal that gastrointestinal dysfunction is occurring. Some of the most common causes include:

◦ Low stomach acid creates a variety of other digestive issues such as pathogenic bowel colonization, acid reflux, food allergies, and severe nutritional deficiencies. Stomach acid restoration protocols, in addition to treating acid reflux can also be extremely helpful for constipation.

Note: Symptomatic low stomach acid is extremely common (e.g., Senator Ron Johnson shared that learning about this allowed him to treat his chronic acid reflux).

◦ A disrupted gut microbiome (which conversely often becomes disrupted by bowel stasis).

◦ Hormonal shifts (e.g., some women develop constipation during pregnancy, menopause, or with hormone replacement therapy). Because of this, it is vital to be aware of this issue, and if applicable, work with a hormone specialist who can address it.

◦ Dysfunction within the autonomic nervous system (which amongst other things is a common consequence of many of the constipation triggering drugs and psychiatric states I discussed above).

• Habits and exercise — Our modern lifestyle (e.g., with its constant stress) predisposes many of us to be constipated. Fortunately, once we recognize what’s happening, we can easily address much of it. We find the following are the most problematic:

◦ Individuals not allowing themselves the time to go to the bathroom when they need to defecate, as once they miss this window, they often subsequently cannot.

Note: Within Chinese medicine, it is believed that different organs activate at certain times in the day.29 In that system, the colon activates between 5 to 7 AM, and I’ve had numerous patients who have found if they do not use that time to have a bowel movement, it’s often quite difficult for the rest of the day.

◦ Peristalsis depends upon movement within the rest of the body. For this reason, sedentary lifestyles greatly reduce the inherent motion within the gastrointestinal tract and treating constipation often requires addressing a lack of physical activity.

◦ The position we go to the toilet on.

Squatting

Something many people don’t realize is that the modern toilet is a relatively new invention, and that prior to it, rather than sitting, humans squatted to go to the bathroom.30 Additionally, sitting toilets are primarily a Western creation, so as one goes to many other societies, squatting toilets are much more common (although they are gradually being phased out as a sitting toilet is seen as a sign of affluence). For example, toilets like these are commonly seen throughout Asia.

Note: One of the interesting things about this design is how much less water it uses (whereas by contrast, standard toilets account for approximately 30% of the average home’s indoor water use).31

Unfortunately, due to our anatomy, this positional change is much more problematic than we realize as it compresses the rectum and hence makes it much harder to force feces through it.

In turn, many find that if they squat while defecating, this significantly eases bowel movements (e.g., I periodically hear this story from patients who went to Asia and had to use squat toilets there). Sadly, however, like many other harmful modern cultural practices (e.g., there are a variety of issues with wearing bras such as it causing breast cancer), the importance of the position we defecate in is rarely recognized.

Conclusion

One of the things I find the most unfortunate about the constipation subject is that due to it being “inappropriate” to discuss, many patients simply don’t bring it up. Because of this, despite being a widespread problem in our society, little is still known about constipation and many unwise approaches are used to manage it.

I hence believe the subject deserves much more attention than it gets, and again and again I’ve seen just how significantly a person’s quality of life can improve once their bowels start functioning again. In many cases, the fix isn’t complicated — but finding what actually works requires stepping outside the standard model and taking the time to look at the full picture.

The good news is that once you start connecting these dots and supporting your body’s natural processes — most people can get their digestive system back on track without becoming dependent on pills. It just takes looking at the whole picture instead of treating constipation like it’s some mysterious, unsolvable problem when the answers are often hiding in plain sight or simply doing what our ancestors used to.

Arthritis affects more than 53 million adults in the U.S., making it one of the most common causes of chronic pain and disability.1 It’s a group of conditions marked by joint pain, stiffness, swelling, and reduced mobility — enough to turn everyday tasks such as climbing stairs, carrying groceries, or rising from a chair into painful challenges.

The burden is also growing. The U.S. Centers for Disease Control and Prevention (CDC) reports that more than 40% of adults with arthritis already face limits on their daily activities, and the number of Americans diagnosed is projected to climb from 53.2 million to 78.4 million by 2040.2

The toll reaches beyond discomfort: arthritis raises the risk of falls and fractures and adds more than $2,000 in health care costs per person each year. Yet one of the most effective non-drug strategies for managing arthritis isn’t found in a pill bottle. Research indicates regular physical activity may help reduce pain, support mobility, and preserve independence — without the side effects of medication.

Despite that, the message rarely reaches the people who need it most: only 15% of adults age 65 and older meet recommendations for both aerobic and muscle-strengthening exercise, even though nearly half of adults in that age group have arthritis. A recent CDC-published report — a nationwide survey assessing health care providers’ knowledge of arthritis-appropriate exercise recommendations — reaffirms the case that movement is one of the most effective non-drug strategies for managing arthritis.

How Movement Supports Arthritis Management

A report published in the CDC’s Preventing Chronic Disease journal examined arthritis management and highlighted a fact that often gets overlooked: Physical activity is one of the most effective non-drug strategies for reducing arthritis pain and improving physical function.3

Researchers emphasized that regular movement helps people with arthritis improve mobility, function, and overall quality of life. Those improvements translate into practical benefits such as walking farther, climbing stairs more easily, standing up with less discomfort, and maintaining independence as you age.

• Arthritis creates a cycle that movement helps break — Arthritis often leads to joint pain, swelling, and stiffness, which naturally makes people less active. Unfortunately, less movement creates a new set of problems. Muscles weaken. Joints become less stable. Range of motion declines. Everyday tasks become harder. Researchers explained that regular physical activity may help offset that downward spiral by supporting strength, joint mobility, and overall function.

• The goal is consistent movement, not extreme workouts — People with arthritis don’t need intense exercise programs to see benefits. The CDC recommendation is at least 150 minutes of moderate-intensity physical activity each week along with two days of muscle-strengthening exercise. Moderate intensity simply means moving enough to raise your heart rate and breathing while still allowing you to carry on a conversation.

Many people hear “150 minutes per week” and immediately assume they need long gym sessions. The researchers stressed a much simpler message: every bit of movement counts. A few short walks, a brief stretching session, or several activity breaks spread throughout the day all contribute toward your weekly goal. That approach makes exercise less intimidating and easier to sustain over time.

• Several arthritis-friendly activities stood out — The CDC highlights brisk walking, swimming, yoga, dancing, gardening, and community exercise classes as examples of activities that help people stay active while being gentle on their joints.4

The best exercise is often the one you enjoy enough to repeat consistently. Walking helps improve mobility and endurance. Swimming helps reduce stress on painful joints. Yoga helps maintain flexibility and range of motion. Gardening and dancing keep you moving while providing enjoyment and purpose.

• Strong muscles protect vulnerable joints — Researchers emphasized that strength training deserves a place alongside aerobic exercise. The muscles surrounding your knees, hips, shoulders, and other joints act like support structures that help absorb force during movement. When those muscles weaken, more stress shifts directly onto already-irritated joints. Strengthening those muscles may help improve stability, reduce strain, and make daily activities easier.

• Less sitting is almost as important as formal exercise — The report encouraged people with arthritis not only to exercise regularly but also to reduce sedentary time throughout the day. Long periods of sitting allow joints to stiffen and muscles to become inactive.

Frequent movement breaks help maintain circulation, preserve flexibility, and may aid in preventing the gradual decline associated with inactivity. Even standing up, stretching, or taking a short walk every hour helps keep your body engaged.

• Many health care providers underestimate the power of exercise — Only about 60% of participating health care providers correctly identified current exercise recommendations for adults with arthritis before completing the educational program — meaning roughly 4 in 10 did not.

After the training, more than 82% reported improved awareness of evidence-based exercise programs and their benefits. This finding highlights how important it is for patients to understand that exercise is not merely an optional add-on. It’s a core part of arthritis management.

Arthritis often convinces people that movement causes more harm than good. The evidence reviewed in this report points in the opposite direction. Regular physical activity may help improve pain, mobility, and function. Every walk, stretch, strengthening exercise, or gardening session becomes a step toward maintaining the abilities arthritis tries to take away.

Make Movement Part of Your Arthritis Routine

For most people with arthritis, the most effective tool isn’t found in a pill bottle — it’s consistent movement. The CDC researchers emphasized that regular physical activity ranks among the most effective non-drug strategies for reducing arthritis pain and improving physical function.

The next step is understanding how to put that research into practice so you can move more comfortably, strengthen the muscles that support your joints, and create an environment that allows your body to recover rather than remain trapped in chronic inflammation.

1. Start with movement, not perfection — If you have arthritis, your goal is not to become an athlete overnight. Your goal is to move more than you did yesterday; any physical activity is better than none. A 10-minute walk around your neighborhood, a few minutes of stretching after breakfast, or a short gardening session all count. Think of it like earning points. Every movement session adds to your weekly total. Those small wins build momentum and confidence.

2. Rebuild joint support with smarter strength training — Weak muscles force painful joints to do more work than they were designed to handle. That’s why strength training is considered one of the most important tools for supporting arthritis symptom management. Traditional weight training, however, often feels intimidating when your knees, hips, shoulders, or hands already hurt.

Blood flow restriction training (BFR), including KAATSU, offers a different approach, but because it involves deliberately restricting circulation, it’s best started with a physical therapist or trained coach, and worth clearing with your doctor if you have cardiovascular or clotting conditions. Special bands are used to partially restrict blood leaving the working muscles.

By briefly trapping blood in the working muscle, this method is thought to mimic some of the low-oxygen conditions associated with heavier lifting, allowing the muscle to be trained with lighter weights. Research in healthy adults has found that walking with blood flow restriction can increase muscle size and strength even at low training loads5 — for example, using a 3-pound weight instead of a 15-pound weight.

These findings come from studies in the general adult population rather than people with arthritis specifically, so individual results may vary.

The advantage for arthritis sufferers is that you strengthen the muscles that support and stabilize your joints without placing excessive mechanical stress on already vulnerable tissue. As your muscles become stronger, everyday activities may become easier. Standing up, climbing stairs, carrying groceries, and walking longer distances may require less effort.

Many people also regain something equally important: confidence in their ability to move without fear. If arthritis has left you feeling like your body is working against you, this type of low-load strength training offers a practical path toward rebuilding stability, mobility, and independence.

To learn more about KAATSU, check out my previous article, “How to Stay Fit for Life,” in which I explain in greater detail how to use it. The main difference between KAATSU and BFR is the tool you’re using. BFR can be done with restriction bands, but KAATSU uses a device that also provides intermittent and not just constant pressure. The KAATSU set is ideal as it is far easier to dial in to the correct pressures.

You also get the benefit of intermittent pressure automatically, without having to adjust the bands yourself. I recommend the C5 model, because the C-series doesn’t have Bluetooth (which emits harmful electromagnetic fields).

For nearly 40 years, beta blockers have been a standard prescription after a heart attack. Today, more than 80% of patients who survive an uncomplicated myocardial infarction leave the hospital with one of these drugs.1 A myocardial infarction, better known as a heart attack, occurs when blood flow to part of the heart becomes blocked, causing damage to heart muscle. Symptoms often include chest pain, pressure, shortness of breath, nausea, dizziness, and pain that spreads into the arm, jaw, or back.

Left untreated, a heart attack leads to permanent heart damage, heart failure, or death. But what if that reflexive prescription, written millions of times a year, may be doing little for many of the people who receive it?
A major international study published in The New England Journal of Medicine set out to test whether beta blockers still earn their place now that heart attacks are treated very differently than they were when the practice began.2 The answer is forcing cardiologists to reconsider a habit four decades in the making.

More unsettling still is what surfaced when researchers separated women from men. A drug that looked merely unnecessary for one group behaved very differently in the other — a divergence sharp enough that the investigators are now urging doctors to drop the assumption that the same therapy serves everyone equally.

Landmark Trial Challenges Routine Beta-Blocker Use

The New England Journal of Medicine study, known as the REBOOT trial, enrolled 8,505 patients from 109 hospitals in Spain and Italy who recovered from a heart attack with relatively normal heart function.3

Participants were randomly assigned to receive either beta-blocker therapy or no beta-blocker therapy while all received contemporary standard cardiac treatment. Beta blockers work by blocking adrenaline from reaching the heart, which slows the heart rate and eases the force of each beat — the same action that explains both their intended effect and many of their side effects.

• Patients with preserved heart function saw no meaningful improvement — Researchers followed participants for a median of 3.7 years and found that the combined rate of death, repeat heart attack, and hospitalization for heart failure was virtually identical between the two groups — 22.5 events per 1,000 patient-years among beta-blocker users versus 21.7 events per 1,000 patient-years among nonusers.

• Beta blockers did not reduce the risk of death — During follow-up, 161 patients taking beta blockers died compared to 153 patients who did not receive the drugs. Researchers found no meaningful reduction in mortality despite the long-standing practice of routinely prescribing beta blockers after heart attacks.

• The drugs also failed to prevent additional heart attacks — Researchers recorded 143 repeat heart attacks in the beta-blocker group and 143 in the group that did not receive beta blockers. These identical numbers suggest the medication offered no measurable protection against future cardiac events in this patient population.

• Hospitalizations for heart failure remained largely unchanged — Researchers documented 39 heart-failure admissions among beta-blocker users and 44 among nonusers, a difference that was not statistically significant. In practical terms, beta blockers did not reduce the likelihood of returning to the hospital for heart failure after recovery.

• Advances in modern treatment appear to have reduced the need for routine beta-blocker use — Most participants received additional care, including procedures to restore blood flow, statin therapy, and antiplatelet medications. The findings suggest that a treatment once considered indispensable after a heart attack no longer provides added benefit for many patients whose heart function remains preserved after modern treatment.

Women Saw Higher Risks Instead of Higher Protection

A REBOOT substudy published in the European Heart Journal took a closer look at whether women and men responded differently to beta blockers after a heart attack.4 Researchers analyzed data from 8,438 participants in the REBOOT trial, including 1,627 women and 6,811 men, to determine whether beta blockers affect women and men differently after a heart attack.
Earlier beta-blocker trials included too few women to provide clear answers, making this one of the most comprehensive analyses to date conducted on female heart attack survivors.

• Women taking beta blockers experienced significantly worse outcomes — Women assigned to beta-blocker therapy experienced 30.4 primary outcome events per 1,000 patient-years compared with 21 events per 1,000 patient-years among women who did not receive the drugs. Overall, beta-blocker use was associated with a 45% higher risk of death, repeat heart attack, or hospitalization for heart failure in women.

• The difference in death rates was notable — Researchers recorded 46 deaths among women receiving beta blockers compared with 24 deaths among women who were not prescribed them. The death rate reached 16.3 per 1,000 patient-years in the beta-blocker group versus 8.6 per 1,000 patient-years in the control group, representing nearly double the mortality risk among women taking the medication.

• The risk became more apparent as follow-up continued — Participants were monitored at three, 15, 36, and 48 months after enrollment. Over time, researchers observed a growing separation between women who received beta blockers and those who did not, showing that the negative effects were not limited to the immediate recovery period after a heart attack.

• Higher doses and better heart function were linked to the worst outcomes — The harmful effects were most evident among women whose hearts maintained stronger pumping function after their heart attack and among those receiving higher beta-blocker doses. Rather than creating greater protection, larger doses were associated with poorer outcomes in these women.

• Men did not experience the same pattern, highlighting important biological differences — Researchers found no meaningful differences between treatment groups in men. The study notes that women and men process and respond to medications differently due to differences in pharmacokinetics and pharmacodynamics, terms that describe how drugs move through the body and how the body responds to them.
These findings support a more individualized approach to treatment rather than assuming the same therapy benefits everyone equally.

Focus on What May Support Your Heart

Beta blockers are not harmless drugs. They slow the heart and reduce how forcefully it pumps. This effect helps many people with heart failure, but it also creates a long list of side effects that many patients struggle with every day. Beta blockers commonly constrict peripheral arteries, which reduces blood flow to your hands and feet. As a result, many users report cold hands and feet, fatigue, dizziness, light-headedness, and reduced exercise tolerance.

Many people also experience mood swings, depression, trouble sleeping, nausea, weight gain, sexual dysfunction, shortness of breath, low blood pressure, and an excessively slow heart rate. Some patients describe feeling like they have lost their energy and motivation. Some beta blockers — particularly older, non-selective types like atenolol — also reduce insulin sensitivity, which has been linked to an increased risk of Type 2 diabetes.5

If you’ve been told beta blockers are the answer after a heart attack, the research tells a different story for many patients with preserved heart function. Your long-term protection may depend on addressing the underlying factors that contribute to heart damage in the first place.

When your mitochondria — the tiny energy-producing structures inside every cell — become dysfunctional, your entire cardiovascular system suffers. The goal is to help restore cellular energy production, support metabolic health, and strengthen the systems that keep your heart functioning properly. If you’re currently taking a beta blocker, don’t stop on your own — talk to your prescriber first.

1. Eliminate linoleic acid (LA) from your diet — Seed oils like soybean, corn, canola, cottonseed, sunflower, and safflower oils are one of the biggest threats to mitochondrial function. They’re found throughout the food supply, including chips, salad dressings, sauces, fried foods, restaurant meals, and many packaged products. These oils are the primary source of LA, a polyunsaturated fat that accumulates in your tissues and contributes to mitochondrial dysfunction.
Replace seed oils with more stable fats such as grass fed tallow, ghee, or butter. Keep your LA intake below 5 grams per day. If you’re able to reduce it below 2 grams daily, that’s even better.
Removing excess LA may help address one of several factors that contribute to cardiovascular disease and impaired cellular energy production. The Pax health platform includes Food Buddy and the Seed Oil Sleuth. This is a special feature designed to help identify hidden sources of LA in your diet as well as estimate your total daily intake.

2. Fuel your cells with the right carbohydrates — Your heart requires a tremendous amount of energy every day. That energy is produced most efficiently when your cells have access to adequate glucose. If you follow a low-carb diet, your mitochondria often operate under unnecessary stress.
Aim for roughly 250 grams of carbohydrates daily from whole fruits, white rice, root vegetables, and other well-tolerated carbohydrate sources. If you struggle with bloating, digestive symptoms, or gut dysfunction, begin with easier-to-digest foods such as fruit and white rice before gradually expanding your choices. Supporting energy production at the cellular level gives your heart the fuel it needs to function efficiently.

3. Walk daily to support your heart — Research suggests walking is one of the most effective cardiovascular habits available. It supports healthy circulation, blood pressure, oxygen delivery, and mitochondrial energy production. Every step may support your body’s ability to generate more adenosine triphosphate (ATP), the energy currency that powers every cell.

Work toward one hour of walking each day. If that feels overwhelming, begin with 10- to 15-minute walks after meals. Consistency matters far more than intensity. Over time, daily movement may become one of the most valuable tools for supporting cardiovascular resilience.

4. Use sunlight to strengthen cellular energy — Sunlight supports mitochondrial function. Exposure to natural light may stimulate nitric oxide release, supports your circadian rhythm, and supports the production of protective mitochondrial melatonin inside your cells. These effects may support energy production throughout the body, including in your heart.
But be aware that if your body is loaded with LA from seed oils, your skin burns faster. Until you’ve been off LA for six months, avoid peak sun hours between 10 a.m. and 4 p.m. Instead, aim for early morning or late afternoon light, which is still highly beneficial.

5. Measure insulin resistance with the HOMA-IR test — Insulin resistance is considered one of the strongest risk factors for cardiovascular disease. Long before blood sugar reaches diabetic levels, insulin resistance has been linked to blood vessel damage, inflammation, and impaired energy production.
The HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) test is a widely used diagnostic tool that can help assess insulin resistance through a simple blood test, so you can spot issues early and make necessary lifestyle changes.
Created in 1985, it calculates the relationship between your fasting glucose and insulin levels to evaluate how effectively your body uses insulin. Unlike other more complex tests, HOMA-IR requires just one fasting blood sample, making it both practical and accessible. The HOMA-IR formula is as follows:

HOMA-IR = (Fasting Glucose x Fasting Insulin) / 405, where

• Fasting glucose is measured in mg/dL
• Fasting insulin is measured in μIU/mL (microinternational units per milliliter)
• 405 is a constant that normalizes the values

If you’re using mmol/L for glucose instead of mg/dL, the formula changes slightly:

HOMA-IR = (Fasting Glucose x Fasting Insulin) / 22.5, where

• Fasting glucose is measured in mmol/L
• Fasting insulin is measured in μIU/mL
• 22.5 is the normalizing factor for this unit of measurement

Anything below 1.0 is generally considered a healthy HOMA-IR score. If you’re above that, you’re considered insulin resistant. The higher your values, the greater your insulin resistance. Conversely, the lower your HOMA-IR score, the less insulin resistance you have, assuming you are not a Type 1 diabetic who makes no insulin.
Interestingly, my personal HOMA-IR score stands at a low 0.2. I attribute this, in part, to my body’s efficiency in burning fuel, which may reflect increased glucose availability from my diet. By incorporating additional carbohydrates into my diet, I aimed to provide my cells with more readily available energy. My personal experience suggests that strategic dietary adjustments may support better insulin sensitivity and metabolic performance, though individual results can vary.

FAQs About Health Risks of Beta Blockers

Q: Do beta blockers still help after a heart attack?
A: A large international study found that beta blockers did not reduce the risk of death, repeat heart attack, or hospitalization for heart failure in patients who recovered from a heart attack with preserved heart function. Researchers followed more than 8,400 patients for nearly four years and found virtually identical outcomes between those who took beta blockers and those who did not.

Q: Why were beta blockers prescribed after heart attacks for so many years?
A: Beta blockers became standard treatment decades ago, before modern heart attack care included rapid artery-opening procedures, complete revascularization, and advanced antiplatelet medications. Researchers believe many of the benefits seen in older studies have been replaced by these newer treatments.

Q: Did the research find any differences between women and men?
A: Yes. A follow-up analysis of the REBOOT trial found that women taking beta blockers experienced a 45% higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who did not receive the drugs. Men did not experience the same pattern, suggesting that women and men respond differently to these medications.

Q: What are some common side effects of beta blockers?
A: Common side effects include fatigue, cold hands and feet, dizziness, low blood pressure, depression, mood changes, trouble sleeping, sexual dysfunction, weight gain, shortness of breath, and a slow heart rate. Some beta blockers — particularly older, non-selective types like atenolol — also reduce insulin sensitivity, which has been linked to an increased risk of Type 2 diabetes and can worsen low blood sugar episodes in people who use insulin.

Q: If beta blockers aren’t the answer, what should I focus on instead?
A: The research points to the importance of addressing several factors linked to cardiovascular disease. Key strategies include eliminating seed oils rich in LA, supporting insulin sensitivity, eating enough carbohydrates to support cellular energy production, walking daily, getting regular sunlight exposure, and monitoring metabolic health with tools such as the HOMA-IR test.

Insulin resistance is one of the most common — and overlooked — drivers of modern disease. It develops quietly over time, long before blood sugar tests show a problem, leaving you tired after meals, hungry too soon and stuck with belly fat that refuses to move. When ignored, it sets the stage for diabetes, heart disease, and premature aging.

Exercise remains a powerful way to restore insulin sensitivity and stabilize blood sugar naturally. But not all movement affects your metabolism in the same way. Some forms train your muscles to burn energy more efficiently, while others fine-tune your immune system and mitochondria — the energy factories inside your cells — to resist stress and inflammation.

Research published in 2025 is helping to pinpoint which types of exercise deliver the biggest benefits for metabolic health, longevity, and cellular repair. The latest findings reveal that the way you move has a direct impact on how your body heals and regenerates — insights that could change the way you think about fitness, aging, and disease prevention.

Weightlifting Reprograms Your Metabolism to Fight Insulin Resistance

A study published in the Journal of Sport and Health Science compared resistance (weightlifting-like) and endurance (wheel-running) exercise in obese mice fed a high-fat diet.1 Both exercise types limited overall fat gain versus sedentary controls, but resistance training produced greater improvements in glucose and insulin tolerance. In other words, resistance-trained mice managed blood sugar more effectively and displayed healthier insulin sensitivity than endurance-trained or sedentary mice.

• Resistance training reduced fat accumulation without major muscle growth — Mice in the resistance exercise group had significantly less visceral and subcutaneous fat than sedentary high-fat-diet mice.2

These benefits occurred without notable increases in muscle mass, showing that improved glucose control wasn’t driven by muscle growth alone. The metabolic benefits weren’t the result of “getting bigger,” but of training the body to use energy more intelligently. Even modest resistance work was enough to reprogram metabolism and sharpen insulin response.

• Endurance training boosted stamina, not metabolism — The endurance-trained mice developed stronger hearts and better exercise capacity, but their blood sugar and insulin sensitivity barely budged.

This shows that while cardio strengthens the cardiovascular system, it doesn’t have the same direct impact on metabolic repair that resistance training does. If your goal is to fix insulin resistance and stabilize energy, building muscle strength is far more effective than logging endless miles.

• Each training style worked through its own biological pathway — Both resistance and endurance exercise offered protection against fat gain, but the mechanisms were completely different.

Resistance training enhanced insulin sensitivity across multiple tests, while endurance training primarily influenced cardiovascular remodeling and protein signaling related to muscle endurance. The researchers found no measurable changes in mitochondrial function or insulin-signaling proteins, meaning the metabolic benefits from lifting came from whole-body adaptation rather than one isolated pathway.

• Shorter, focused resistance sessions proved highly effective — The resistance-trained mice achieved these metabolic benefits through brief, repeated effort-based lifting — not extended endurance sessions. For people managing blood sugar or insulin resistance, this means targeted strength training offers faster, more efficient improvements than longer, high-volume cardio routines.

• Resistance training trains your body to act younger — Lifting weights — or any form of resistance-based exercise — teaches your body to handle glucose like a metabolically healthy person again. It restores the sensitivity of your insulin receptors, reduces fat storage, and keeps energy steady throughout the day. In the context of modern sedentary living and processed diets, resistance exercise isn’t just about strength — it’s metabolic medicine.

Cardio Keeps Your Immune System Young and Energetic

While resistance training fine-tunes how your body handles blood sugar and fat, endurance exercise targets a different — but equally important — system: your immune defense. The next study reveals how steady, moderate cardio acts like a rejuvenation switch for your immune cells, keeping them energetic, adaptable, and far more resistant to the effects of aging.

Published in Scientific Reports, the study examined how long-term endurance training affects immune system function in older adults.3 The study focused on natural killer (NK) cells, a key part of your immune defense that hunts down and destroys infected or abnormal cells.

As people age, these immune cells often lose energy and efficiency, leaving them more vulnerable to infections, cancer, and slower recovery. Scientists sought to determine whether years of consistent cardio exercise could reverse or slow this decline.

• Trained older adults had stronger, more energetic immune cells — The researchers compared men over age 60 who had performed endurance training for decades with untrained men of the same age group.

Those who regularly engaged in endurance training showed dramatically improved NK cell metabolism — meaning their immune cells produced more energy and functioned like those of much younger adults. In short, their immune systems behaved as if they had “turned back the clock.” The trained group also had lower levels of chronic inflammation, an underlying factor in nearly every age-related disease.

• Endurance training helped immune cells make energy more efficiently — In people who regularly did cardio exercise, their NK cells produced energy in a cleaner, steadier way. They used oxygen to turn food into energy, which kept them active and strong for longer periods.

In comparison, people who didn’t exercise relied on a quicker, less efficient system that burned through sugar fast and left their immune cells tired. This is one reason older adults who stay active tend to bounce back from illness or injury much faster.

• Long-term cardio training helped the body resist stress and immune fatigue — When the researchers exposed the participants’ NK cells to common metabolic stressors, the trained group’s cells remained stable and continued functioning at a high level.

Inactive individuals had NK cells that were easily disrupted under the same conditions, showing weaker resilience. For anyone over 50, this means regular endurance activity doesn’t just maintain fitness — it teaches your immune system to handle stress better.

• The effects extended beyond immunity into cellular longevity — Endurance-trained participants showed enhanced mitochondrial density and efficiency — meaning they had more and healthier mitochondria in their NK cells.

Mitochondria act like rechargeable batteries that fuel every cellular process. With age, mitochondria often degrade, leading to fatigue, slower healing, and increased disease risk. Regular cardio effectively recharged these “batteries,” improving the body’s energy economy at the most fundamental level.

• Too much cardio typically backfires — balance is key — Cardiologist Dr. James O’Keefe’s research found that doing intense exercise for four to seven hours a week actually erased many of its health benefits.4 Pushing too hard too often puts your body under chronic stress instead of helping it recover. The takeaway: find your exercise sweet spot with moderate, consistent activity that leaves you energized, not exhausted.

How to Supercharge Strength Gains with Blood Flow Restriction (KAATSU) Training

Blood flow restriction (BFR) training — also called KAATSU — was developed in Japan in 1966 by Dr. Yoshiaki Sato and has since become one of the most effective ways to build strength without heavy lifting. It involves placing soft cuffs or bands around your upper arms or thighs to gently restrict blood flow while exercising. This limited circulation triggers your body to adapt as though it were lifting heavy weights, even when you’re only using light resistance or bodyweight.

• The key is mild oxygen restriction that boosts growth signals — When blood flow is partially reduced, oxygen levels in the working muscles drop — a state called hypoxia. This low-oxygen environment activates powerful biochemical messengers known as myokines.

These anti-inflammatory compounds promote muscle growth, improve hormone balance, and stimulate protein synthesis, the cellular process that builds new muscle fibers. Your body interprets this “low-oxygen challenge” as intense training, even though the actual load is light and joint-friendly.

• You gain strength and protect your joints at the same time — One of KAATSU’s greatest benefits is that it delivers measurable strength gains with very little mechanical stress.

Older adults, those recovering from injury or anyone hesitant to lift heavy weights can use BFR to maintain or increase muscle mass safely. Because the muscles still experience metabolic fatigue, you get the same cellular and hormonal benefits of heavy training — without the joint pain, muscle strain, or long recovery times.

• The secret lies in how your body reacts to the “fake” stress — By briefly restricting venous blood flow, KAATSU tricks your muscles into working harder than they actually are. This encourages your vascular tissue to become more elastic and resilient.

When I interviewed KAATSU expert Steven Munatones, he explained that this “biohack” allows your muscles to work and your vascular tissue to become more elastic. You don’t feel the pain of heavy lifting, yet your muscle fibers and blood vessels are being trained just as effectively. The result is stronger muscles, healthier circulation, and improved energy efficiency — especially in older adults.

• It’s simple to integrate KAATSU into everyday life — You can use BFR bands during strength workouts, walking sessions, or even while doing light chores. The goal isn’t to fully cut off blood flow — just to apply gentle pressure that challenges your circulation.

Keep each session short, around 15 to 20 minutes, and focus on movements like squats, curls, lunges, or pushups using minimal resistance. To learn more, check out my previous article, “How to Stay Fit for Life,” in which I review the science behind KAATSU and explain in greater detail how to use it.

• The main difference between KAATSU and BFR is the tool you’re using — BFR can be done with restriction bands, but KAATSU uses a device that also provides intermittent and not just constant pressure. The KAATSU set is ideal as it is far easier to dial in to the correct pressures. You also get the benefit of intermittent pressure automatically, without having to adjust the bands yourself.

I recommend the C5 model, because the C-series doesn’t have Bluetooth (which emits harmful electromagnetic fields). For a limited time, you can get 10% off any KAATSU equipment by using the promo code DRM.

If I were stranded on a desert island or knew the world was ending and I could only bring a few therapies with me, one of them, without a doubt, would be DMSO. This is because:

It effectively addresses acute injuries (e.g., sprains) and chronic musculoskeletal disorders (e.g., arthritis).
It’s one of the most effective pain killers in existence.
It treats severe, often incurable illnesses and prevents long-term disability.
It’s one of the safest medically active substances available.

Yet, despite it taking the world by storm in the 1960s and thousands of studies being performed that corroborated its benefits, outside of it being a laboratory chemical or an alternative therapy some people use for joint pain, few are even aware of DMSO’s existence.

This was due to the FDA waging a multi-decade long war against DMSO (despite widespread outcry from Congress and the public).

What Is DMSO?

Dimethyl Sulfoxide (DMSO) exists throughout nature1 and has two breakdown products within the body.

Most of it is oxidized to methylsulfonylmethane (MSM — a commonly used joint healing supplement), while a small amount is reduced to DMS and gives rise to DMSO’s characteristic “side effect” a distinctive garlic or clam-like odor that is excreted through the mouth and skin for a few hours that some individuals have difficulty tolerating.

Note: Individuals with insufficient oxidation (who are in a state of reductive stress) are more likely to produce DMS. In turn, when this is addressed, their “DMSO odor” often disappears.

Due to its unique chemistry, DMSO has two remarkable properties:

It acts as a near-universal solvent (e.g., it interacts with a vast range of biomolecules).2,3
It’s able to pass through biological membranes without damaging them (something to my knowledge, nothing else can do).4

Because of this, DMSO will rapidly enter the body (including the brain) regardless of its route of administration (e.g., within 5 minutes after going on the skin it can be found in the blood,5 and within an hour it can be found within the bones6), but simultaneously does not accumulate within the body.7

DMSO, in turn, has an almost endless number of uses as it can be applied in almost any manner. Almost any drug or substance can be combined with it and administered through the skin (e.g., steroids, NSAIDs, vitamin C, or hydrogen peroxide). In many cases, the effect of those drugs is enhanced, and simultaneously, their toxicity is reduced (although, in some cases, the toxicity increases).

Cellular Protection

DMSO’s ability to spread throughout the body (including into the brain) initially seems concerning — however rather than be toxic to cells, DMSO heals them and protects them from damage from many otherwise lethal stressors (e.g., heat, blood loss, radiation, sonic shockwaves).

For example, since DMSO does not expand when it freezes and greatly lowers the freezing point of cells, it was a revolutionary substance for preserving frozen cells,8 and likewise, many cases exist of DMSO saving the fingers or toes that otherwise would have required amputation.

Note: Due to the intense scrutiny DMSO received, thousands of papers have been published on its biological effects (including numerous animal safety studies and one where humans were exposed to 3 to 30 times the typical dose for 90 days9) — all of which did not report any significant side effects from DMSO.

In turn, those studies found the most common side effect (affecting 50% to 75% of users) is (reversible) irritation at the site when 70% DMSO is applied topically on the skin (which can be easily mitigated) and the most significant was an allergic reaction in approximately 1 out of every 2000 people (which can easily be screened for).

Circulatory Disorders

DMSO is remarkably effective in managing circulatory disorders, effectively protecting tissues and enhancing blood flow by removing excess fluid, improving circulation, and dissolving clots. Its benefits are particularly evident in conditions like Raynaud’s syndrome, where it eliminated symptoms in 50% of patients,10 and in diabetic circulatory issues, with studies showing over a 94% success11 rate in treating diabetic ulcers.

DMSO also works wonders for varicose veins, often providing noticeable improvements within minutes by strengthening vessel walls and enhancing capillary circulation. In a study of 67 patients with varicose ulcers,12 remarkable responses were documented, even in chronic cases. Additionally, DMSO has been shown to help many other circulatory disorders:13,14

Key mechanisms behind DMSO’s effectiveness include:

• Heart function — It can increase or decrease heart contractions without affecting rhythm, enhancing cardiac output and simultaneously dilates critical blood vessels.15
• Anticlotting properties — DMSO prevents blood clot formation in the body, reduces clot promoting prostaglandins, and is a powerful platelet deaggregator.16,17,18 Its ability to safely block platelet bonding, scavenge harmful radicals, and inhibit tissue factor expression makes DMSO a standout in circulatory health.19

Heart Attacks

Given all of these protective and circulatory enhancing properties, DMSO is an immensely promising treatment for heart attacks and heart attack recovery,20 and this benefit has been demonstrated in numerous animal studies.21,22 Likewise, I and colleagues have had a few situations arise where DMSO was administered to someone having a heart attack and successfully treated it.

Note: We’ve also had some success treating heart attacks by rapidly restoring someone’s physiologic zeta potential.

DMSO and Strokes

Roughly 3.1% of adult Americans have experienced a stroke23 (a figure we expect to rise from the COVID-19 vaccines). Each year, this translates to about 800,000 people in the United States having a stroke, in 2022, 165,393 dying and between 20% to 40% of survivors experiencing long term disability.24

Because of the harm strokes pose to society, and the rate at which brain tissue deteriorates once its blood supply is lost, the medical system prioritizes treating strokes as soon as possible.

Strokes come in two main types: ischemic (caused by clots blocking blood flow) and hemorrhagic (due to ruptured blood vessels). The standard treatment for ischemic strokes is tPA,25 a clot-busting drug. However, administering tPA can be deadly if the stroke is hemorrhagic, so patients need to first wait for a CT scan before receiving it.

Furthermore, tPA is only effective within a limited time frame (up to 3 to 4.5 hours26), and only a small percentage of patients (1.8% to 8.5%) actually receive it. Among those who do, only 13%27 see significant improvement. Additionally, tPA can cause serious bleeding complications28 (e.g., 6.4% risk29 of a symptomatic brain bleed) and can’t eliminate larger clots.

In short, strokes remain a leading cause of death and disability worldwide.30 This highlights the need for a better treatment that can safely:

Effectively treat ischemic strokes
Has no risk of worsening a hemorrhagic stroke
Could easily be taken at home, and more importantly, be quickly given on ambulances
Protected brain tissue from dying
Prevented reperfusion injuries
Healed damaged brain tissue after a stroke

DMSO has been known for over 50 years to do just that. For example, a 2002 trial with DMSO combined with fructose diphosphate (FDP — a source of cellular energy) indicated that 63% of elderly patients experienced improved neurological status when treated within 12 hours of a stroke, compared to only 20% with standard care.31

One of the most important aspects of this trial was that while DMSO is the most helpful when given immediately after a stroke, the trial showed DMSO could save the neurons long after the stroke had happened.32

Given the existing options for strokes, a trial like this should have been immediately replicated by premier institutions around the world — but instead almost no one even knows it happened.

Note: Numerous animal studies (listed here) have also demonstrated DMSO’s effectiveness in treating ischemic strokes. Sadly this revolutionary medical treatment remains a forgotten side of medicine.

After I learned how unconscionable the FDA’s prohibition against DMSO was, I made a point to begin telling people I felt were at risk of a stroke to stock DMSO at home, and since then, I’ve had instances where someone (or their caretaker) called me up, described a stroke, I gave them instructions on what to do (since they already had DMSO at home), and by the time they got to the ER, the stroke was “resolved.”

Note: In my opinion, IV DMSO would have been ideal (and more effective) in those situations, but in each case, it was not feasible to implement.

Likewise, many compelling cases have been recorded33 of individuals who treated their strokes with DMSO:

“A Los Angeles school teacher suffered a major stroke just after Christmas, found unconscious at home. Immediately, she was treated with DMSO: first applied topically to her head and then given by intramuscular injection — all without ever going to the hospital, thanks to a family friend’s advice.

Remarkably, she regained consciousness later that day and continued daily DMSO treatments. By the time school resumed in January, she was back teaching, fully recovered and without any mention of her ordeal. She continued her teaching career until retirement, healthy and free of disability.”

In another case, a woman in a coma for three months after a stroke showed no signs of life. Daily topical DMSO treatment was started, and within a month, her brain began to respond. After four months, she returned home and began a regimen of daily DMSO in water alongside topical applications. Three years later, she was living a normal life with only a slight speech defect, claiming her memory was sharper than her husband’s.

Note: There are also many reported cases of individuals who took DMSO for musculoskeletal or pain disorders (by far the most common use of DMSO) who then experienced a permanent improvement of stroke symptoms.

Hemorrhagic Strokes and Traumatic Brain Injuries

While ischemic strokes are difficult to treat, hemorrhagic ones (and other traumatic brain injuries) are even more challenging, and after decades, there has been surprisingly little progress in neurologic intensive care, particularly in preventing long-term paralysis and disability.34

“It was, as if the hand of God had somehow touched the [experimental] animal’s forehead. ‘I don’t believe it,’ I stammered. But it was true. I felt a tingling in my spine because this reawakening of a virtually dead animal had all the markings of a medical breakthrough.

Instead, the discovery, the potential for saving lives and the continued research that should have uncovered other uses for dimethyl sulfoxide and similar agents was quietly laid to rest in the coffers of forgotten medicine.”

Note: Dr. Jack de la Torre’s observations were partly based on the fact he saw numerous animals with flatlined EEGs (which typically precede brain death and then actual death) have the EEGs come back within 10 minutes of receiving DMSO.

In cases of severe brain bleeds, key challenges like increased intracranial pressure (ICP) and inflammation can severely damage brain tissue. Common treatments often fail, leading to further complications (e.g., the most commonly used ICP lowering agents like mannitol can create a “rebound ICP” which is higher than it was at the start).

Remarkably, DMSO35 effectively lowers ICP36 without the rebound effect seen with other agents, while enhancing cerebral blood flow and reducing inflammation.

Research shows DMSO can significantly improve outcomes in traumatic brain injuries. In several studies, patients with elevated ICP experienced rapid decreases in pressure and improved neurological function after DMSO treatment. For instance, one study demonstrated a drop in ICP within 30 minutes for patients with closed head trauma, leading to long-term neurological improvement.37

Additionally, DMSO also addresses many other critical aspects of traumatic brain injuries and brain bleeds (which under conventional care requires many different drugs):

Animal studies further support these findings, showing DMSO’s ability to reduce brain swelling and improve survival rates in models of brain injury. Its unique properties make it a standout option in neurocritical care, addressing multiple challenges associated with brain injuries.38 To put all of this into context:

“A January 11, 1981, a news report39 in the Ocala Star Banner [page 6], carried the headline: ‘DOCTOR CLAIMS DMSO SAVED 11.’ The story read:

SAN DIEGO (AP) — A doctor at the University of San Diego credits the controversial drug DMSO with saving the lives of 11 people who suffered severe head injuries. Dr. Perry E. Camp, a UCSD Medical School neurosurgeon, said Friday that dimethyl sulfoxide was effective for 11 of 30 people judged near death and for which other lifesaving methods have proved useless.

‘To take patients like that and have even one out of 10 survive is phenomenal,’ Camp said. ‘The fact that we have any survivorship at all … doesn’t sound like much, but it is extremely encouraging,’ Camp said.”

Sadly, however, despite the immense amount of research conducted and these results being dramatically better than what the standard of care can offer, this remains an almost completely forgotten side of medicine.

Note: Many of the same principles hold true for concussions, and the pioneers of DMSO felt it was an essential treatment for athletes after they experienced one — particularly since unhealed concussions can predispose the athlete to long-term cognitive issues (e.g., both boxers and professional football players have a threefold risk of dementia).40,41

Spinal Cord Injuries

“We used to think that the damage caused at the moment of injury in a severe head or spinal cord injury was irreversible. But now there are animal studies and a handful of clinical cases that tell us something different. There is still a little bit of time before the injured cells die.

Based on what we’ve seen in animal studies and a handful of human situations, we think that if you can treat a head injury victim within a few hours of the injury, or a spinal cord victim within one hour, there is a good chance of preventing death or the paralysis that would otherwise occur.” — Dr. Jack de la Torre

As much of the same pathology that causes permanent damage in the brain also occurs in the spinal cord (the loss of blood flow and compressive post-traumatic swelling), DMSO can produce miraculous results.42 Despite decades of research, steroids remain the standard treatment, even though they’re largely ineffective and come with significant side effects.43 In fact, spinal surgeons often use steroids simply to avoid lawsuits.44

The greatest success comes when DMSO is administered intravenously within 90 minutes of injury.45 For example, dogs that were expected to be paralyzed after spinal cord trauma regained nearly normal function after DMSO treatment.

Numerous other animal studies have also shown46 DMSO prevents spinal cord injuries from causing paralysis, and in humans numerous miraculous stories exist, such as a 16-year-old quadriplegic girl gradually regained organ function and eventually walked after a year of DMSO therapy. Even older injuries see results — one man, paralyzed for 12 years, regained some feeling and movement after using a DMSO lotion.

Cognitive Impairment and Dementia

Since many neurological disorders are linked to poor blood flow to the brain, previous traumas (e.g., concussions or microstrokes), the accumulation of misfolded proteins or an autoimmune process (all things DMSO is also remarkably effective at treating), it stands to reason that many cognitive disorders would respond to DMSO.

In turn, we find that much in the same way DMSO reverses many other complications of aging (e.g., skin issue, hair loss, poor organ function) IV DMSO is one of the most effective antiaging therapies for the brain (along with ultraviolet blood irradiation or improving the physiologic zeta potential).

Likewise, IV DMSO is one of the only therapies I know of which can help challenging neurological diseases like Multiple Sclerosis, Parkinson’s, and ALS. Likewise, I periodically come across anecdotes of DMSO consuming centenarians who have no cognitive impairment despite their age. Numerous animal and human studies demonstrate this. For example:

• 18 patients with probable Alzheimer’s disease47 were treated with DMSO and tested regularly for nine months, with great improvements being noted after only three months of treatment, and becoming especially noticeable after six months of treatment. Areas of improvement included memory, concentration, and communication alongside a significant decrease of disorientation in time and space.

• 100 patients with cerebrovascular diseases48 (e.g., a previous stroke, cerebral embolism, or a hardening of the arteries of the brain), many of whom were senile received DMSO orally and through intramuscular injections over the course of 50 days. In addition to their coronary heart disease (i.e., atherosclerosis) and high blood pressure improving in 96.12% of them, the observing neurologist noted that their cognition, mood, and behavior improved.

• A study of49 104 elderly adults with a disease process causing impaired cognition found DMSO was highly favorable for both their cognitive and psychiatric function.

Note: Since many psychiatric conditions are neurological in nature, DMSO has also been shown to be remarkably effectively here (e.g., a study50 found it had a 100% success rate in treating acute schizophrenia, and an excellent effect on psychosis from manic-depression or alcoholism, chronic schizophrenia, anxiety, and obsessive compulsive disorder).

Conclusion

DMSO was discovered during a time when the scientific community was open to exploring unconventional ideas, as science had not yet been handcuffed by a grant system designed to thwart unconventional ideas. In turn, thousands of studies were published on its potential, thanks to dedicated researchers with strong institutional support.

However, despite this promising research, the FDA suppressed its development, consigning years of scientific effort and countless animal sacrifices to the dustbin of history.

This is particularly tragic given the immense suffering caused by conditions that DMSO could alleviate. Decades of research and billions of dollars later, conventional medicine still struggles to treat many of these disorders effectively. Dr. Pierre Kory, after reviewing this article, shared my sentiments:

“In over 15 years of running ICUs and treating brain injuries, strokes, and bleeds, it saddens and infuriates me to know an intervention like DMSO could’ve helped so many. The treatments I relied on were often limited or came with major risks.”

My goal in presenting this work is to give DMSO another chance to flourish and help those in need. I sincerely thank you for your attention and allowing me to do this!

Long ago, before refrigeration was invented, early humans preserved their food in different ways. One of the most common methods is drying meat, fruit, and vegetables under the sun. Pickling, curing, and fermenting were also used, depending on a particular culture’s practices. All the same, the goal was to prevent their food supply from spoiling so that they didn’t have to consume them immediately.1

As industrialization expanded and the need for immediate access to food grew, companies began experimenting with chemicals to extend shelf life of their products. Examples include the use of nitrites, sodium benzoate, and sulfites.2 Over time, more preservatives were added to the food supply, prolonging the shelf life of processed goods so they can be shipped to consumers all over the world.

However, this gradual expansion of chemical additives has far-reaching consequences. Today, there are at least 950 substances in the American food supply that are actually banned in Europe due to their possible health effects, CBS News reports. And the worst part is that these ingredients are not required to be listed on product labels.3

As awareness of the impact of ultraprocessed foods on human health rises, so does the scrutiny of the ingredients used in their manufacturing. Research has linked them to rising rates in chronic disease,4 and a 2026 study noted that the very preservatives Big Food uses to extend shelf life of their products is causing cancer.5

Higher Preservative Intake Tracks with Higher Cancer Rates

A study published in The BMJ examined how everyday exposure to food preservatives influences cancer risk. Researchers analyzed long-term dietary data from the French NutriNet-Santé cohort, a large prospective study designed to follow people over time and observe how diet links to disease development.6

The team focused on preservative additives as a category, then broke them down into specific chemical groups and individual compounds. The reason for following this angle was simple: No study had completely focused on preservatives as a root cause for disease, despite their prevalence in the food supply.

• Key findings of the study — Participants came from the general adult population, which included both men and women with diverse dietary patterns and health backgrounds. Over a follow-up period that averaged 7.57 years, the researchers recorded new cancer diagnoses and compared them against levels of preservative intake.
The findings were clear — people who consumed more preservatives had higher rates of overall cancer and breast cancer. This association remained after accounting for factors such as age, body weight, physical activity, smoking, alcohol intake, and overall diet quality.
• The study separated preservatives into antioxidant and non-antioxidant categories — Non-antioxidant preservatives showed the clearest signal. Higher intake of this group tracked with higher overall cancer risk and higher breast cancer risk. Within that category, sorbates and sulfites stood out.
Potassium sorbate, a compound commonly used to prevent mold growth in packaged foods, and potassium metabisulfite, often used in processed foods and beverages, each showed positive associations with cancer incidence.
• The link between sodium nitrite and prostate cancer — Sodium nitrite often appears in processed meats to preserve color and prevent bacterial growth. Men with higher intake showed higher prostate cancer incidence compared to those with lower exposure.
• The results followed a dose-response pattern — As preservative intake increased, cancer risk increased alongside it. In practical terms, this means every packaged snack, every preserved deli meat, every shelf-stable convenience food adds another brick to a wall of cumulative risk.
• The paper also compared preservative effects with broader food patterns — Preservatives often appear in ultraprocessed foods, yet the authors adjusted for overall ultraprocessed food consumption. Even after doing so, preservative intake retained its association with cancer outcomes. This comparison tells you that preservatives themselves deserve closer studying, not only the general category of processed foods.
The study also explored the mechanisms to clarify these associations. One aspect involves nitrosation chemistry. Nitrites and nitrates convert in the body to form N-nitroso compounds, which are carcinogenic.7
• Another mechanism is oxidative stress and inflammation — Oxidative stress refers to an imbalance between damaging molecules and the body’s ability to neutralize them. Considering this, the paper cited experimental evidence showing that some preservatives trigger inflammatory signaling and oxidative injury in cells. Chronic inflammation creates an environment where damaged cells survive and multiply, a known contributor to cancer development.
• Concerns about microbiome disruption were also raised — Preservatives often serve antimicrobial roles by design. Inside the gut, this antimicrobial action alters bacterial populations and weakens the gut barrier. When the gut microbiome loses its integrity, bacterial toxins move into your bloodstream easier, driving systemic inflammation.
• An implication of the findings — The authors acknowledged that their observational research does not prove a direct causation. However, they stressed that consistency across additive categories, dose-response relationships, and alignment with toxicological data strengthen confidence in the findings. Still, the results warrant action even without absolute proof, because the exposure is so widespread and the disease outcomes carry high stakes for the public.

Preservatives Track with Rising Diabetes Risk

If preservatives increase the risk of cancer, what other chronic diseases can they fuel? A companion study from the same research team, now published in Nature Communications, looked at metabolic health and noticed similar patterns. Using the same dataset from the French NutriNet-Santé cohort, the researchers followed participants over time, tracked detailed dietary records, and identified new cases of Type 2 diabetes as they occurred.8

The goal was to isolate preservative exposure and see whether it predicted diabetes risk beyond known factors such as body weight, physical activity, and overall diet quality. The study population included adults from the general community, many of whom entered the study without diagnosed metabolic disease. Over a follow-up period that averaged 8.05 years, higher preservative intake consistently aligned with higher incidence of Type 2 diabetes.

• Effect of total preservative exposure — Again, as overall intake increased, diabetes incidence rose hand in hand. When the authors examined preservative subgroups, non-antioxidant preservatives again showed the strongest association.
Within this category, sorbates stood out, particularly potassium sorbate. Individuals with higher intake of this additive experienced a higher rate of Type 2 diabetes compared with those who consumed less. Potassium sorbate appears in a wide range of packaged foods marketed as stable, which makes exposure easy to overlook in daily life.
• Risk goes up over time — Diabetes cases accumulated gradually across years of follow-up, aligning with sustained exposure rather than short-term dietary changes. The data suggest that consistent preservative intake acts as a chronic stressor rather than an acute trigger.
• Differences across participant groups — Diabetes associations appeared stronger among individuals with otherwise balanced diets. This challenges the assumption that generally healthy eaters remain protected if they still rely on packaged foods with additives. Even when the rest of the diet looked favorable, preservative exposure tracked with diabetes incidence.
• Mechanistic explanation of the findings — The authors discussed several biological pathways supported by experimental evidence. One pathway involves gut microbiota disruption. Preservatives suppress bacterial growth by design. In the gut, this shifts microbial balance, weakens the intestinal barrier, and increases systemic inflammation. Chronic low-grade inflammation interferes with insulin signaling, meaning cells stop responding efficiently to insulin’s message to absorb glucose.
Another mechanism involves oxidative stress and metabolic signaling. Experimental data cited in the paper show that certain preservatives increase oxidative markers and impair glucose handling in tissues. Over time, this disrupts how muscles and the liver manage blood sugar, setting the stage for insulin resistance.
• The consequences of unchecked consumption — Type 2 diabetes increases risk of heart disease, kidney failure, vision loss, and nerve damage.9 Because diagnosis often occurs late, prevention hinges on identifying modifiable exposures early. Preservatives represent one such exposure because they appear across many foods and remain invisible unless you read labels carefully.

By pointing out preservatives as a distinct factor, this study presents a shift on how you think about the progression of diabetes. Simply put, risk does not hinge solely on the consumption of refined sugar or weight gain, although those certainly play a part, too. Chemical additives built into the food supply influence how your body handles glucose over the long-term.

Lower Your Exposure to Harmful Food Additives with These Tips

Health authorities have allowed countless preservatives into the food supply without proper safety testing, but that doesn’t mean they’re unavoidable. Here are my recommendations to help you protect yourself and your loved ones:

1. Steer clear of ultraprocessed foods — Ultraprocessed foods contain long ingredient lists filled with unfamiliar terms, which are most likely loaded with substances your body was never meant to process, and that includes preservatives. In addition, these products rely heavily on other chemicals, such as emulsifiers and artificial flavorings that disrupt metabolic function and compromise gut health.
Focus instead on whole, minimally processed foods such as grass fed meats and dairy, fresh fruits and vegetables, and healthy carbohydrate sources like white rice. The simpler and more natural the ingredients, the better they support your health.
But here’s another thing about ultraprocessed foods — they’re loaded with linoleic acid (LA), which is another good reason to avoid them in the first place. As I noted in my study, published in Nutrients, excess LA intake affects your cellular health, leading to chronic disease.
I recommend you minimize your LA intake to less than 5 grams per day, but if you can get it to below 2 grams, that’s even better. To help you monitor your intake, sign up for the upcoming Mercola Health Coach app. It contains the Seed Oil Sleuth, which is a feature that will calculate the total LA in your food to a tenth of a gram.
2. Prioritize eating a clean, organic diet when possible — Organic foods are far less likely to contain chemical food additives, synthetic pesticides, or hormone-disrupting compounds. Whenever you can, choose organic versions of produce, leafy greens, fruits, and meats.
Organic certification standards restrict the use of artificial dyes, preservatives, and flavor enhancers, helping reduce your overall exposure to hidden toxins.
But what if organic food is out of your budget? I recommend you browse through the Environmental Working Group’s (EWG) Shopper’s Guide to Pesticides in Produce.10 It contains a list of fruits and vegetables that contain the lowest and highest levels of detected pesticides based on their testing.
3. Learn how to read ingredient labels — Many harmful additives are concealed behind misleading names. Artificial sweeteners such as aspartame, preservatives like BHT, potassium sorbate, sodium nitrite, and emulsifiers including polysorbate 80, have all been associated with gut dysfunction and metabolic issues.
Get into the habit of scanning ingredient lists and avoiding products with vague terms like “natural flavors” or “modified food starch.” If an ingredient is unfamiliar, research it before consuming the product.
4. Use safer food packaging and storage methods — Chemical exposure doesn’t stop with what you eat — it also comes from what your food touches. Plastic containers, particularly those containing bisphenol A (BPA) or phthalates, can leach hormone-disrupting chemicals into food. Opt for glass or stainless steel containers for storage and reheating. Never reheat leftovers in plastic, as heat accelerates the release of toxic compounds.
5. Prepare more meals at home — Restaurant meals and packaged foods tend to contain the highest concentrations of preservatives, emulsifiers, artificial colors, and industrial vegetable oils high in LA.
Cooking at home allows complete control over ingredients and preparation methods. Use grass fed butter or ghee in place of vegetable oils, and skip processed seasonings loaded with additives. Making meals from scratch not only reduces chemical exposure but also supports better digestion, sustained energy, and long-term cellular health.

Frequently Asked Questions (FAQs) About the Link Between Preservatives and Rising Cancer Rates

Q: How did humans preserve food before modern preservatives existed?
A: Before refrigeration, people relied on drying, fermenting, curing, and pickling to preserve food. These traditional methods extended shelf life without synthetic chemicals or long-term health tradeoffs.

Q: Why did chemical preservatives become so common in modern food?
A: Industrialization created demand for long shelf life. Manufacturers added chemicals like nitrites, sulfites, and benzoates to stabilize food and maximize distribution efficiency.

Q: What does research show about preservatives and cancer risk?
A: Data showed that higher preservative intake linked to higher cancer rates, especially breast and prostate cancer, with risk increasing as exposure increased over time.

Q: How are food preservatives linked to Type 2 diabetes?
A: Research showed that higher preservative intake tracked with higher diabetes incidence, independent of calories, weight, or sugar, pointing to additives as a metabolic stressor.

Q: What practical steps reduce preservative exposure and health risk?
A: Avoid ultraprocessed foods, read ingredient labels carefully, choose whole and organic foods when possible, store food in safer containers, and prepare more meals at home to limit additive intake.

When it comes to implementing a new supplement routine, most people start out strong. New bottle, fresh resolve, a clear sense that this time will be different. And for a week or two, it is. Then the streak quietly breaks, and within a month the bottle has migrated to the back of a shelf. We tend to blame ourselves for this — call it laziness, lack of discipline, another good habit we couldn’t keep.
That story is wrong, and it’s worth replacing. People don’t stop taking their supplements because they stop caring about their health. They stop because it’s difficult to form new habits.
This is one of the most consistent findings in all of adherence research: adherence fades over time, and fades fast. A real-world analysis that tracked how reliably people kept up with a simple once-daily medication found that the share taking it as directed slipped from 60.3% at six months to 41.5% at one year, and to just 30.1% by the two-year mark.1
Same people, same good intentions, same easy schedule — and within two years, most had drifted off course. If that happens with a single pill that people have every reason to take, what chance does a shelf full of optional supplements have?

The Story We Tell Ourselves Is Wrong

When the routine falls apart, almost everyone reaches for the same explanation: “I failed; I’m just not disciplined enough.” It’s a tidy story, and it puts the blame in a familiar place — on you. It’s also wrong, and it has quietly ended more health efforts than any actual lack of willpower ever has.
Here’s the truth. The thing that predicts whether people keep going isn’t character. It’s load. In a multicenter study of older adults managing several conditions at once, three-quarters reported a high treatment burden and more than two-thirds did not take their medications as directed.
The strongest drivers of that burden weren’t personality or motivation — they were the complexity of the regimen and the sheer number of things to take.2 In plain terms: the heavier and more complicated you make a routine, the more reliably people abandon it. So let’s retire the self-blame. You didn’t lack the willpower. You were handed a routine that almost no one, however motivated, manages to sustain.

The Friction Stack

To see why, look at what a typical supplement routine actually asks of a busy person. Remember which bottles to take. Remember when. Count out a small fistful of capsules. Find water. Get them all down without gagging on the big one. Do it again at lunch with a different set. Refill the organizer on Sunday so the week doesn’t fall apart. Reorder before you run out.
None of these steps is hard on its own. That’s what makes the burden easy to underestimate. But stacked together, every single day, on top of a life already full, those tiny demands start to feel like another series of nagging obligations. Before you know it, you miss a dose — and it hardly seems to matter. Then you miss another, and the routine starts to unravel. Before long, the bottles sit untouched. The miracle isn’t that people quit. It’s that anyone keeps it up at all.

Why the Usual Fixes Don’t Work

This is the hidden friction the supplement industry has never wanted to talk about, because for most products there’s no good answer to it. When the industry does acknowledge the problem, its answer is almost always to push the work back onto you. Buy a better pill organizer. Set a phone alarm. Download an app that nags you. The unspoken message is that the routine is fine and you simply need to try harder to tolerate it.
The research is unkind to that idea. When investigators put the obvious high-tech fix to the test in a randomized trial — a medication-management app with daily reminders, adaptive text messages, and even phone calls from a real person — it made essentially no difference.
Adherence was already high in both groups and statistically identical, and the authors noted plainly that simple reminders had repeatedly failed to solve the problem.3 (The trial was modest in size and stopped early, so it isn’t the last word — but it fits a long pattern.) You can remind someone all day long; if the underlying routine is a burden, the reminders just become one more thing to ignore.
There’s a deeper reason these fixes fall short. Behavioral scientists call it the intention-behavior gap — the wide, well-documented gulf between meaning to do something and actually doing it, day after day. In one qualitative study of people trying to sustain a long-term routine for their own health, researchers linked that gap less to weak intentions and more to the absence of easy, ongoing support; when keeping up required continuous effort and vigilance, even committed people slid.4

We Drew the Opposite Conclusion

We looked at the same problem and came to a very different place. If the burden is what makes people quit, then removing the burden is the entire job. That means reducing the number of doses and amounts to take and reducing the number of decisions you have to make each day.
Part of the solution is to lean into a food-first format so that your supplement regimen feels like it’s part of a meal instead of a medical event. It means a routine simple enough that it survives a chaotic Tuesday, a work trip, a sick kid, a week when everything goes sideways. This is the opposite of the industry’s instinct. Where the old model adds, we subtract. The goal is to create supplements you’ll actually use, because a supplement you don’t take is useless.
The proper role of nutritional supplements is right there in the name. They’re intended to support the nourishment you get from whole foods, not to replace meals or excuse a poor diet. The pill model makes targeted support feel like a separate task, something that is apart from your daily nourishment. A food-first format corrects that mismatch.
It keeps the priority where it belongs: eat real food, then add focused support to that food where it makes sense. The format itself reinforces the hierarchy instead of blurring it. You are not using supplements to cover for bad habits. You’re making a good meal work harder for you.
That shift matters because it aligns the product with the behavior you want to protect. Caring for yourself no longer has to mean one more ritual off to the side, detached from the food on your plate. It becomes part of the same act.
The food-first strategy also restores something the old model quietly took from you: the sense that you’re capable of taking care of yourself. When a routine is built to fail, every lapse feels like proof that you can’t be trusted to follow through. When a routine is built to fit real-world living, following through stops being a test you keep failing and becomes something that is sustainable in the long term.

The Bottom Line

You are not the problem. The reason most people stop taking their supplements has nothing to do with weak character and everything to do with a design that has a low chance of success in the first place. The evidence is remarkably consistent: complexity and pill count drive people away, reminders don’t rescue a routine that’s too heavy, and good intentions can’t close the gap on their own. Blaming yourself for quitting a routine that almost no one sustains isn’t just unfair — it’s aimed at the wrong target entirely.
So, we set out to remove the burden rather than ask you to endure it. Fewer things to take, a food-first format, a routine light enough to survive a real life. Do that, and consistency takes care of itself. Not because you became someone new, but because, for once, the thing was built for the person you already are.

Frequently Asked Questions

Q: What role does willpower play in maintaining a supplement regimen?
A: Willpower exists, but leaning on it is a losing strategy. Motivation rises and falls for everyone, and any routine that depends on feeling inspired every single day will eventually meet a day you don’t. The research is clear that what predicts whether people keep going is how heavy and complicated the routine is — not how disciplined they are. Make the routine light enough and willpower barely enters into it.

Q: Won’t a reminder app or a pill organizer fix the problem?
A: They help a little, but they don’t solve it. When the underlying routine feels like a burden, reminders just become one more stressor and another thing to tune out — which is exactly what controlled trials of high-tech reminder systems have found.

Q: Why does a food-first format make a supplement regimen easier to stick with?
A: Because it’s attached to something you already do every day. Eating happens daily, in a stable context. Folding a supplement into a meal means there’s no separate ritual to remember and no extra step to skip.

Q: Does reformulating a supplement from a pill to a powder mean I’m getting a less effective product?
A: No. It means the product is designed around what you’ll actually keep doing. A simpler routine you can follow indefinitely will do far more for you than an elaborate one that you’ll abandon in a month. Removing friction isn’t about doing less for your health — it’s about making sure the supplement actually gets used.

For decades, people have been told that a glass of wine a day protects your brain. That belief is now collapsing under the weight of new evidence. A comprehensive study — tracking more than half a million adults across the U.S. and United Kingdom — shows that alcohol harms your brain at every level of consumption.1

Dementia is a progressive disease that steals memory, reasoning, and independence. While genetics and aging play a role, lifestyle factors are increasingly recognized as major drivers — and alcohol use stands out as one of the most damaging. Even light drinking is now linked to measurable brain injury.

Instead of protecting cognition, alcohol impairs mitochondrial energy production, damages neurons, and accelerates the biological aging process that leads to dementia. The truth is simple: there’s no safe amount of alcohol when it comes to preserving your brain. This evidence marks a major shift in understanding — one that replaces decades of wishful thinking with hard data.

Genetic Evidence Confirms That Every Drink Raises Dementia Risk

For a study published in BMJ Evidence-Based Medicine, researchers analyzed data from 559,559 adults aged 56 to 72 to uncover how drinking affects long-term brain health.2 These participants were followed for up to 12 years, with 14,540 developing dementia during the study.

The research combined traditional observational data with a genetic method that uses people’s DNA to reveal whether a behavior actually causes disease rather than just correlates with it. This powerful approach allowed scientists to separate cause from coincidence.

• The findings overturned decades of public health messaging — Earlier studies had suggested a U-shaped curve — meaning moderate drinkers supposedly had lower dementia risk than both heavy drinkers and abstainers. This analysis proved that pattern was misleading.

When genetic data were included, the U-shape flattened into a straight, upward slope: the more alcohol people consumed, the higher their dementia risk became. Light drinking offered no protection at all. Alcohol is not a nutrient or a tonic. It’s a neurotoxin that gradually undermines memory, mood, and cognition.

• Researchers found that every level of drinking increased risk — Using genetic proxies for lifetime alcohol intake, they discovered that for every standard deviation increase in drinks per week — a statistical term meaning a measurable rise in consumption — dementia risk rose by 15%.

Even small increases in alcohol use disorder prevalence, such as a twofold rise, led to a 16% higher risk of developing dementia. This means that even a few extra drinks a week have measurable consequences on your brain health.

• The illusion of safety in moderate drinking was caused by reverse causation — People in early stages of dementia often begin drinking less as their brain function declines. When studies compared them with healthy moderate drinkers, it looked like those who drank lightly were healthier — but in reality, their lower risk had nothing to do with alcohol.

It was simply that those already showing symptoms of cognitive decline had stopped drinking. This false signal distorted decades of research and led millions to believe that moderate alcohol intake was harmless, even beneficial.

• The research also revealed who is most at risk — Across European, African, and Latin American ancestry groups, those with alcohol use disorder consistently showed elevated dementia rates. People drinking more than 40 drinks per week faced the steepest risk, but even those drinking far less weren’t exempt. In both men and women, genetic risk for heavier drinking predicted higher dementia incidence, demonstrating that the danger spans all populations.

Alcohol’s Brain Effects Have Far-Reaching Public Health Implications

Based on their findings, the scientists estimated that cutting alcohol use disorder rates in half could lower dementia cases by roughly 16% globally. This doesn’t just apply to people with heavy drinking habits — it means that any reduction in alcohol intake, even among light drinkers, could meaningfully protect brain health. This translates into a simple yet powerful form of prevention: every skipped drink matters.

• Even occasional drinking poses measurable risks — The idea that “just a glass or two” is harmless doesn’t hold up under genetic scrutiny. Every sip increases the burden of oxidative stress and neuronal injury. Alcohol’s impact is cumulative, meaning that damage adds up over years, not weeks.

This makes it especially dangerous for younger adults, who may not notice effects until midlife. The findings strongly suggest that if you want to preserve your mental clarity into older age, lowering or eliminating alcohol is one of the most effective steps you can take.

• Your choices today shape your cognitive future — Whether you drink socially, occasionally, or regularly, this research shows that the dose-response curve for alcohol and dementia risk has no safe zone.

The higher the intake, the greater the damage. If you’ve believed that “a little” alcohol supports health, it’s time to rethink that narrative. Your brain’s longevity depends on protecting its cells from preventable harm — and alcohol is now proven to be a direct and avoidable threat.

Few substances have captured my attention as profoundly as methylene blue. Earlier this year, I engaged in an in-depth discussion with Georgi Dinkov, a respected expert in metabolic health, who shed light on the multifaceted benefits of this remarkable compound.1

Methylene blue, a quinone-like molecule, is not just another supplement; it’s a powerful agent that can play an important role in cellular metabolism. By accepting and donating electrons, methylene blue enhances mitochondrial function, addressing issues like reductive stress that are often overlooked in conventional medicine.

This conversation with Dinkov highlights methylene blue’s role in reaching optimal health and treating a myriad of conditions, ranging from mental health disorders to acute medical emergencies.

Methylene Blue and the Electron Transport Chain

Methylene blue has the ability to integrate seamlessly into the electron transport chain (ETC), which plays a role in cellular energy generation. Unlike traditional antioxidants that either donate or accept electrons and subsequently require excretion, methylene blue possesses the unique capability to cycle between its oxidized and reduced forms indefinitely.

This continuous electron transfer process ensures sustained improvement in mitochondrial efficiency, which is key for energy production and overall cellular health. Dinkov emphasized that methylene blue acts as an emergency oxidant, stepping in to accept electrons even when essential co-actors like NAD+ are deficient.

This makes methylene blue capable of resolving metabolic issues associated with electron buildup and reductive stress. By maintaining the flow of electrons within the ETC, methylene blue prevents the stagnation that leads to cellular dysfunction and various health problems.

Methylene Blue for Enhanced Brain Health

The therapeutic potential of methylene blue is vast and varied, extending across a spectrum of neurological and psychological conditions. Dinkov shared insights into several studies where methylene blue, even at relatively low doses of 15 to 50 milligrams (mg), demonstrated significant benefits in treating treatment-resistant depression and psychosis.2

These findings are groundbreaking, suggesting that methylene blue enhances cognitive function and stabilizes mood by improving mitochondrial performance and reducing oxidative stress in the brain. Methylene blue enhances the benefits of niacinamide (vitamin B3) on brain health and metabolism.3 Furthermore, in terms of neurodegenerative diseases, methylene blue has shown remarkable promise.

A modified version of methylene blue, developed by a UK-based company, has been patented for Alzheimer’s treatment. Clinical trials have reported an astounding 80% reversal of Alzheimer’s symptoms in participants, according to Dinkov, highlighting methylene blue’s ability to not only halt but also reverse cognitive decline.4

These applications underscore the compound’s role in enhancing brain health by ensuring efficient energy production and mitigating the damaging effects of oxidative stress. A stabilized form of methylene blue known as hydromethylthionine (LMTM) also shows promise in treating mild to moderate Alzheimer’s disease.5

Unlike traditional methylene blue, LMTM is a stabilized dihydromesylate salt, which offers improved pharmacokinetic properties, including better brain uptake and longer half-life in humans. The study involved 1,162 patients across two Phase III trials and revealed a concentration-dependent activity of LMTM on cognitive decline and brain atrophy.

Notably, the optimal therapeutic dose was identified around 16 mg a day, which maximizes cognitive benefits without the diminishing returns observed at higher doses of 150 to 250 mg per day. This plateau effect underscores that beyond a certain concentration, no additional benefits are observed, aligning with the study’s findings that higher doses do not confer extra advantages.

Moreover, LMTM demonstrated significant benefits both alone and as an add-on to existing Alzheimer’s treatments. Patients receiving LMTM showed reduced cognitive decline and slower brain atrophy compared to those with lower plasma levels. This suggests that even at lower, more manageable doses, LMTM effectively slows the progression of Alzheimer’s by enhancing mitochondrial function.

Methylene Blue’s Life-Saving Benefits in Septic Shock

Expanding methylene blue’s therapeutic applications, a systematic review and meta-analysis published in Critical Care Explorations evaluated the efficacy and safety of methylene blue in patients with septic shock,6 a condition with high mortality rates.

The analysis included six randomized controlled trials encompassing 302 patients and sought to determine whether methylene blue administration could improve outcomes compared to placebo or usual care.

The findings suggest that methylene blue may significantly reduce short-term mortality, shorten the duration of vasopressor use by approximately 31 hours, and decrease hospital length of stay by about two days.

Additionally, methylene blue was associated with an increase in mean arterial pressure at six hours post-administration. Importantly, the study did not find an increase in adverse events.

Methylene blue functions by inhibiting endothelial and inducible nitric oxide synthase, thereby counteracting the profound vasodilation characteristic of septic shock. By restoring vascular tone, methylene blue helps maintain adequate organ perfusion and oxygenation, which are necessary for patient survival.

Methylene Blue for Cancer Treatment — Targeting Ovarian Tumors

Research is also exploring methylene blue as a treatment for ovarian cancer, particularly in cases resistant to conventional chemotherapies. A study published in Cancers (Basel) used a carboplatin-resistant ovarian cancer tumor model in mice to assess the impact of methylene blue on tumor growth.7

The findings revealed a significant in vivo reduction in tumor proliferation among mice treated with methylene blue compared to those receiving carboplatin alone or no treatment. Specifically, methylene blue demonstrated superior tumor suppression, highlighting its effectiveness against chemoresistant ovarian tumors.

Further in vitro analyses provided insights into the mechanisms underlying methylene blue’s anticancer effects. The study examined the impact of methylene blue on mitochondrial energetics in both cancerous and normal cell lines. Methylene blue altered the oxygen consumption rate and mitochondrial membrane potential in the ovarian cancer cells, suggesting enhanced mitochondrial respiration and induction of apoptosis.

In contrast, normal cells exhibited a markedly different response, with less pronounced changes in mitochondrial function, indicating a selective targeting of cancer cell mitochondria by methylene blue.

The combination of methylene blue with a mixture of lipoic acid and hydroxycitrate and carboplatin was investigated to evaluate synergistic effects. While the combination therapy showed a modest enhancement in tumor response compared to methylene blue alone, the difference was not statistically significant. Importantly, the metabolic therapies did not induce toxicity or weight loss in the treated mice, underscoring the favorable safety profile of methylene blue-based treatments.

By targeting the altered mitochondrial function and inducing apoptosis in chemoresistant cancer cells, methylene blue offers a novel approach that could improve treatment outcomes for patients facing limited options. The differential response between cancerous and normal cells also suggests that methylene blue selectively targets tumor metabolism, minimizing harm to healthy tissues.

Methylene Blue in Emergency Situations, Including Heart Attack

Beyond its chronic health benefits, methylene blue proves invaluable in acute medical emergencies. Dinkov elaborated on its effectiveness in treating conditions such as cyanide and carbon monoxide poisoning. In these scenarios, methylene blue acts swiftly to restore cellular respiration by accepting electrons and facilitating the utilization of oxygen, thereby reversing the toxic effects of these poisons.

I also recommend having methylene blue readily available at home in case of a heart attack. While sudden death is the most common symptom of heart disease, surviving individuals face the serious threat of reperfusion injury, where cellular dysfunction and death may worsen following the restoration of blood flow.

Methylene blue administration significantly mitigates tissue damage; however, proper dosage is important to avoid overdose. Administer methylene blue within minutes of the cardiac event to meet the critical time threshold.

In cases of stroke or heart attack, even a single dose below 50 mg may be life-saving. This rapid benefit makes methylene blue an essential tool in emergency medicine, offering a quick and efficient means to counteract metabolic crises.

I strongly advocate for the inclusion of methylene blue in emergency kits, as its ability to stabilize metabolic function swiftly provides an additional layer of protection against sudden, life-threatening metabolic disturbances. The potential of methylene blue to act as a universal antidote in various poisoning scenarios underscores its significance in both medical and emergency settings.

Methylene Blue and Antiaging Benefits

The antiaging properties of methylene blue is another exciting frontier that Dinkov passionately discussed.8 Studies have indicated that methylene blue reverses aging in human cells by maintaining optimal mitochondrial function and reducing oxidative damage, which are key factors in the aging process. Daily doses ranging from 5 mg to 50 mg help achieve the necessary concentration for these benefits without causing discoloration in urine or tissues.

Moreover, when combined with red light therapy, methylene blue’s effects are significantly amplified. This synergy promotes cellular rejuvenation and longevity by enhancing mitochondrial efficiency and reducing oxidative stress, thereby combating the visible signs of aging and supporting overall cellular health.

Dinkov mentioned an innovative approach where methylene blue is used in a dilution similar to mouthwash as an oral rinse, offering antiseptic benefits without the harsh side effects of conventional mouthwashes.9 This application not only leverages methylene blue’s metabolic benefits but also integrates it into daily routines for enhanced health and longevity.

Beyond the primary benefits discussed, methylene blue exhibits several other promising properties that could significantly enhance various aspects of health and medicine. Dinkov mentioned that methylene blue acts as a powerful aromatase inhibitor at sub-micromolar concentrations, which could have implications in managing hormone-related conditions.10

Additionally, methylene blue’s ability to enhance the flow of electrons within the electron transport chain makes it a versatile supplement for addressing a wide range of metabolic disturbances. Dinkov also introduced the concept of the “Methylene Blue Test of Health,” where the dosage at which an individual’s urine begins to turn blue serves as an indicator of their metabolic health.11

A lower dosage threshold for this coloration suggests better metabolic function, while higher thresholds may indicate underlying health issues such as cancer or diabetes, which are characterized by extreme reduction states in cells.

This innovative approach provides a simple yet effective method for individuals to monitor their metabolic health and take proactive measures to address any issues. As research continues to unfold, the full spectrum of methylene blue’s benefits will likely expand, positioning it as a cornerstone in both preventative and therapeutic health strategies.

Safety and Dosage Considerations

While the benefits of methylene blue are substantial, Dinkov highlighted the importance of appropriate dosing to avoid severe adverse effects that may occur with high doses, particularly serotonin syndrome — a fatal condition caused by excessive serotonin levels in the brain.

Methylene blue is a potent monoamine oxidase type A (MAO-A) inhibitor, which may dangerously elevate serotonin levels when combined with selective serotonin reuptake inhibitors (SSRIs) or other serotonergic drugs. I would advise strong caution for anyone ever to take an SSRI drug, as I don’t believe anyone benefits from them.

Further, at doses exceeding 30 mg to 50 mg, methylene blue may cause temporary blue discoloration of urine and, occasionally, the tongue. Although harmless, this effect is startling if unexpected. High doses may also interfere with pulse oximeter readings, leading to inaccurate assessments of blood oxygen levels.

Individuals with severe renal insufficiency should use methylene blue with caution and under close medical supervision, as impaired kidney function affects drug clearance. Additionally, methylene blue is contraindicated for patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency due to the risk of hemolytic anemia.

Common side effects associated with methylene blue include mild and transient gastrointestinal discomfort, such as nausea and diarrhea. Allergic reactions, ranging from skin rashes to life-threatening anaphylaxis, are also possible. Neurological effects like headaches and confusion may occur.

Cardiovascular effects, though less common, may include increased blood pressure and palpitations. Furthermore, methylene blue interacts with various medications, particularly antidepressants and antimalarials, altering their efficacy or causing adverse reactions.

To mitigate these risks, Dinkov recommends lower daily doses of methylene blue, typically between 5 mg to 15 mg, especially for long-term use. These dosages are sufficient to harness its metabolic benefits without significantly increasing the risk of serotonin syndrome. Additionally, Dinkov pointed out that while higher doses (up to 50 mg) have shown efficacy in certain therapeutic applications, they need to be approached with caution and under professional supervision.

If you’re considering methylene blue supplementation, consult with a knowledgeable health care professional to tailor the dosage to your specific needs and avoid harmful interactions with other medications.

My Recommendations for Methylene Blue Use

There are three types of methylene blue typically sold — industrial-grade, chemical-grade (laboratory-grade), and pharmaceutical-grade. The only one you should use is the pharmaceutical-grade variety in solid, capsule, or tablet form. Avoid using any solutions of methylene blue as dissolving it in water leads to a significant decrease in its effectiveness after 48 to 72 hours.

Methylene blue is a popular choice in aquarium maintenance due to its antifungal, antiparasitic, and oxygen-transporting capabilities. It’s commonly used to alleviate fish stress, combat fungal infections, and eliminate external parasites like Ich (white spot disease). However, aquarium-grade methylene blue often contains harmful contaminants, including heavy metals, which pose serious health risks to your aquatic pets.

To ensure the safety and well-being of your pets, I strongly advise against using methylene blue products designed for aquariums in any pet-related applications. Instead, choose pharmaceutical-grade methylene blue, which undergoes rigorous testing to confirm it is free from harmful impurities.

Personally, I have eliminated my regular intake of methylene blue, finding that daily walks by the ocean are an excellent way to manage reductive stress naturally. However, in scenarios where I might not have access to the ocean, I would consider taking 5 mg of methylene blue daily, adjusting to 3 mg if I were 75 pounds lighter in weight, and doing so six days a week.

It’s essential to emphasize that the appropriate and legal way to use methylene blue is through a prescription from a qualified physician. If you’re contemplating the use of methylene blue for your health, I strongly encourage you to consult with your doctor to determine if it’s suitable for your specific needs and circumstances.

Chronic disease is the defining health crisis of our time. Despite medical advancements, rates of diabetes, heart disease, cancer, and neurodegenerative conditions continue to rise. The U.S. spends more on healthcare than any other country, yet people are getting sicker, not healthier.

This failure stems from conventional medicine’s narrow focus on pharmaceuticals and procedures that only prolong dependence rather than recognizing the role of mitochondrial function and cellular health in preventing and treating chronic disease. It’s time to challenge this system, expose its shortcomings, and demand a shift toward solutions that actually restore health at its foundation.

The Financial Toll of Lifelong Disease Management

The financial burden of managing chronic diseases is overwhelming, even for those with health insurance. This has made medical debt one of the most pressing economic crises in the United States today.1 The problem is not just that these conditions are expensive — it’s that they are rarely resolved. Patients are placed on lifelong prescriptions and procedures that generate billions in revenue for pharmaceutical and insurance companies while failing to restore health.

• A major study reveals chronic conditions heighten financial vulnerability — A study published in JAMA Internal Medicine2 evaluated more than 2.85 million adults and found that over 38% had at least one chronic condition. While many assume that health insurance protects against major medical expenses, their findings show that those with chronic conditions are much more likely to struggle with unpaid medical bills, delinquent debt, and even bankruptcy.

• As the number of chronic conditions increases, so does the likelihood of financial strain — Among individuals with no chronic illnesses, only 7.6% had medical debt in collections. However, that number skyrocketed to 32% for those with seven to 13 chronic conditions. This pattern was also seen in nonmedical debt in collections, which affected only 7.2% of those without chronic illness but increased to 24% among those with the most medical issues.

• Delinquent debt and poor credit scores are more common with chronic illness — Delinquent debt, meaning missed payments on any type of debt, was found among 14% of healthy individuals, compared to nearly 43% among those with multiple chronic conditions.

The financial toll of chronic illness also extends to credit scores and bankruptcy rates. Individuals with no chronic illnesses only had a 17% chance of having a low credit score, while it was 47% for those managing seven to 13 chronic conditions.

• Bankruptcy rates rise dramatically with more chronic conditions — Bankruptcy rates also climbed, with 1.7% of those with multiple chronic conditions filing for bankruptcy, a fourfold increase compared to the 0.4% of healthy individuals who had to take that step. Beyond the likelihood of accumulating debt, the actual amount of medical debt in collections also increased with each additional chronic condition.

• Unpaid medical debt rises sharply with more chronic illnesses — Among those with no chronic conditions, the average amount of unpaid medical bills in collections was $784. For those with multiple chronic illnesses, that number rose to $1,252. This suggests that even with insurance, the out-of-pocket costs of ongoing treatments, medications, and specialist visits quickly add up, leaving patients financially overwhelmed.

The Soaring Economic Burden of Chronic Disease

Chronic disease is the leading cause of healthcare spending in the United States. According to the Centers for Disease Control and Prevention (CDC),3 90% of the nation’s $4.5 trillion annual healthcare costs go toward treating chronic illnesses, averaging $13,493 per person.4 These expenses include doctor visits, hospital stays, surgeries, and long-term prescription drug use.

• Lost productivity from chronic disease also results in billions of dollars in economic losses each year — In 2022, the indirect costs of diabetes in the U.S. economy were estimated to be $106.3 billion.5 Meanwhile, cardiovascular disease alone is projected to cost the U.S. $1.1 trillion annually by 2035.6

• Chronic illness creates generational financial strain — When declining health forces workers to leave their jobs, the financial strain also affects their entire family. Spouses and children often become full-time caregivers and sacrifice their own careers and financial security in the process.

As medical expenses pile up and income dwindles, families are left trapped in a cycle of economic instability that stretches across generations and makes financial recovery a challenge.

• Even government programs are crumbling under the overwhelming cost of chronic disease — The 2024 Centers for Medicare and Medicaid Services (CMS) financial report7 reveals that Medicare alone accounts for 22% of all U.S. healthcare spending, while Medicaid contributes another 17%. In total, these programs handle over a billion fee-for-service claims each year and represent approximately 13% of total federal outlays.

• Most Medicare and Medicaid funds are likely spent on chronic illness care — Given that chronic disease is responsible for 90% of U.S. healthcare expenditures, it is likely that a substantial portion of these Medicare and Medicaid funds are dedicated to managing chronic conditions.

More than a decade ago, Medicare was already spending vastly different amounts depending on how many chronic conditions a person had.

• Medicare costs escalate dramatically with the number of chronic conditions — In 2010, the average Medicare beneficiary with no or just one chronic illness cost the system $2,025 per year. But for those with two or three conditions, that number jumped to $5,698.

Patients with four or five chronic diseases cost an average of $12,174, while those with six or more racked up a staggering $32,658 annually.8 With chronic illness rates climbing higher every year, it’s safe to assume these figures have only grown worse.

• The system profits from lifelong treatment rather than curing disease — The staggering cost of chronic disease is a reflection of a medical system designed to manage symptoms instead of helping you heal, with billions funneled into medications, surgeries, and treatments that ensure a steady flow of profits for pharmaceutical companies and the medical industry. Even the best-selling drugs in the world aren’t designed to treat disease but to keep you dependent.

• Best-selling medications make billions while diseases persist or worsen — Lipitor, a cholesterol-lowering drug, has made over $150 billion in sales,9 yet heart disease remains the leading cause of death. Similarly, insulin costs continue to climb,10 even though Type 2 diabetes is largely preventable with diet and lifestyle changes.

As long as the system profits from keeping people on medication, prevention and real solutions will be ignored. If you want to break free, you have to start looking beyond conventional medicine.

Patient Burnout — When Medications Become a Life Sentence

The endless cycle of seeking relief without healing is the defining reality for millions trapped in the modern medical system. A patient battling chronic pain, for instance, may begin with a mild prescription for relief, only to find themselves escalating to stronger medications as their condition worsens.

• Opioid prescriptions increase over time but don’t improve patient outcomes — A study published in Pain Medicine11 found that among chronic non-cancer pain patients, opioid prescription rates jumped from 59.6% at baseline to 74.3% over two years, with a disturbing 71% of users remaining on the drugs long-term.

Strong opioid use more than doubled, rising from 13% to 31%. Despite this surge in prescriptions, patients continued to report severe pain and high levels of daily life interference.

• Long-term opioid users experience more pain and rarely discontinue use — Additionally, the study found that opioid users were more likely to experience continuous pain and disability compared to those who were not prescribed opioids. Most notably, only 1% of patients successfully discontinued opioid use over the two-year period, showing how once patients start opioid therapy, they rarely stop, even when their pain does not improve.12

• Opioids worsen pain over time by lowering the body’s pain threshold — Research has also demonstrated that long-term opioid use leads to opioid-induced hyperalgesia, a condition where your nervous system becomes more sensitive to pain rather than less.

Instead of providing lasting relief, opioids rewire your pain pathways, lowering your pain threshold and making discomfort feel even more intense. The very drugs meant to ease your suffering actually exacerbate it over time and trap you in a cycle of increasing pain and drug dependency.13

• For those navigating mental health disorders, the pattern is eerily similar — Brooke Siem, writing for The Washington Post,14 recounts how she spent nearly half her life on antidepressants, never once challenged by a doctor to reconsider the necessity of these medications. Like so many others, she accepted the notion that her only choices were to “cope with depression or cope with antidepressants.”15

Years later, she found herself staring out of her Manhattan high-rise window, contemplating suicide despite the drugs that were supposed to keep her stable. It was only when she withdrew from the medications — which involved an excruciating, months-long process riddled with withdrawal symptoms — that she realized the depth of her dependency.16

• Brooke’s story is unfortunately not a one-off case — It’s estimated that nearly 15.5 million Americans have been on antidepressants for over five years, often without reevaluation.17

Moreover, a 2024 systematic review and meta-analysis published in The Lancet Psychiatry18 found that approximately 15% of individuals who discontinued antidepressants experienced withdrawal symptoms directly caused by discontinuation. In about 3% of patients, these symptoms were severe.

• Polypharmacy reduces quality of life by worsening mental and physical health — A 2021 study in Patient Related Outcome Measures19 also found that patients with a high Drug Burden Index (DBI) — which measures exposure to medications with sedative (e.g., benzodiazepines, opioids) and anticholinergic (e.g., some antihistamines, antidepressants, bladder medications) effects — reported significantly worse psychological well-being, functional limitations, and an overall diminished quality of life.

In other words, the more medications a person takes, the more likely they are to experience cognitive impairment, fatigue, and emotional distress. Even when these drugs are prescribed with good intentions, their long-term effects often make daily life more difficult, not better.

The Hidden Costs of Chronic Illness — Mental, Emotional and Social Strain

If you’re living with a chronic illness, you already know that the struggle goes far beyond physical symptoms — the mental and emotional toll can be just as overwhelming. According to a study published in Middle East Current Psychiatry,20 68.7% of chronic disease patients experience stress, 51.1% suffer from anxiety, and 58.8% struggle with depression.

• Psychological strain is especially severe with multiple chronic conditions — These conditions are particularly prevalent among individuals with cardiovascular disease, metabolic disorders, cancer, respiratory illnesses, degenerative diseases, chronic kidney disease, and chronic liver disorders.

The Patient Related Outcome Measures study21 further confirms that those with three or more chronic conditions are significantly more likely to experience poorer psychological well-being.

• The burden of chronic disease affects patients’ families, too — Research shows that 95% of chronically ill patients rely on a caregiver, usually a family member, to help with daily tasks, medications, and medical appointments.

The demands of caregiving can quickly become overwhelming, leading to exhaustion and emotional strain. Many caregivers struggle with constant fatigue, lack of support, and the heavy responsibility of managing someone else’s health while trying to keep up with their own lives.22

• Moreover, chronic illness leaves you feeling isolated — Fatigue, pain, or mobility issues make it difficult to engage in social activities and lead individuals to withdraw from gatherings and hobbies they once enjoyed. Some friendships fade as plans get canceled and invitations stop coming. The loneliness that follows makes depression worse, creating a cycle that fuels both emotional and physical decline.23

• Chronic illness strains marriages, relationships and even children — If you’re in a marriage or long-term partnership, the shift from equal partners to patient and caregiver can be difficult to navigate.

Research24 shows that chronic illness increases the risk of divorce and relationship breakdowns, often due to financial stress, emotional exhaustion, and a loss of intimacy. If you have children, they may struggle emotionally or academically, as the focus of the household shifts toward managing your condition.25

Ultimately, chronic disease affects every aspect of living. As long as the medical system continues to focus only on symptom management, millions will remain stuck in a cycle that chips away at their quality of life.

Conventional Medicine’s Blind Spot

Modern medicine prides itself on advancements in pharmaceuticals and surgical interventions, yet it has continuously overlooked the most fundamental factor in health — cellular function. Few researchers understood this better than the late Dr. Ray Peat, a biologist and pioneer in bioenergetic medicine and human metabolism, whose work challenged nearly every mainstream dietary and metabolic dogma.

• Cellular energy is the foundation of health — Peat’s research on bioenergetic medicine, which became the foundation of my book “Your Guide to Cellular Health,” emphasizes the central role of cellular energy in disease prevention and health restoration. He rejected the low-carb approach, arguing instead that carbohydrates are essential for fueling mitochondrial function and metabolic health.

• Low-carb diets may harm mitochondrial health by restricting glucose — I was once among those who promoted a low-carb diet, but Peat’s work opened my eyes to the reality that mitochondria thrive on glucose, and that denying your body this essential fuel worsens the very conditions low-carb diets claim to treat.

Instead of promoting caloric restriction and macronutrient avoidance, Peat’s work demonstrates that adequate carbohydrate intake fuels energy production, lowers stress hormones, and supports thyroid function.26

• Peat warned against seed oils and their harmful metabolic effects — Peat was also one of the most vocal critics of polyunsaturated fats (PUFs) found in seed oils, long before mainstream medicine acknowledged their risks.

His research demonstrated how excess linoleic acid, a primary component of seed oils, disrupts mitochondrial function and promotes inflammation.27 While the medical community continues to promote vegetable oils as “heart-healthy,” the bioenergetic model reveals their devastating impact on metabolism.

• Important research like Peat’s has been ignored for not aligning with profit — This is just one instance where groundbreaking research has been systematically ignored in favor of profit-driven dietary guidelines.

Peat’s insights have profound implications for conditions ranging from hypothyroidism to neurodegenerative diseases, yet they remain largely unrecognized by modern medicine. It’s no surprise that conventional medicine dismissed Peat’s work as either too obscure or unworthy of serious clinical consideration, subjecting it to censorship and ridicule.

• The medical industry resists change that could reduce reliance on drugs — This deliberate suppression limited its reach, much like the work of the pioneering researchers he built upon. There is no financial motivation to promote dietary and lifestyle interventions that restore mitochondrial function, reduce pharmaceutical reliance, and reverse chronic disease. After all, the medical industry is structured around profitable treatments rather than disease prevention.

As a result, promising research on cellular health and metabolic therapies remains on the fringes of healthcare, while patients are left to navigate the system on their own. Until the medical establishment shifts its focus to supporting mitochondrial function, addressing nutritional deficiencies, and eliminating toxic exposures, the chronic disease epidemic will continue to spiral out of control. The real solutions to health are not hidden — they are simply ignored.

A Wakeup Call — The Healthcare System Is in Desperate Need of Change

Modern medicine is failing the very people it was meant to help. Chronic disease has reached epidemic levels, yet the healthcare system’s only response is more drugs, more procedures, and more expensive interventions — none of which address the root causes of disease.

Your body isn’t lacking pharmaceuticals; it’s deprived of the essential conditions needed for optimal cellular function. Poor nutrition, metabolic dysfunction, environmental toxins and chronic stress are the real drivers of modern disease. Yet, these factors are overlooked in favor of high-cost, high-profit interventions that do nothing to reverse illness at the cellular level.

This cycle does not have to continue. Real health is possible, but it requires a shift from managing illness to restoring function at the cellular level. Instead of masking symptoms, medicine needs to prioritize the conditions that allow the body to heal itself. The good news is that solutions already exist. Research in bioenergetics and metabolic therapies is paving the way for a future where chronic disease is no longer the norm.

The human body is incredibly resilient when given the right tools, and healing is within reach for those willing to step outside the conventional model. By shifting the focus toward cellular health, the future of medicine can finally move beyond disease management and toward real, lasting vitality.

Frequently Asked Questions (FAQs) About the Root Cause of Chronic Disease

Q: Why does the U.S. spend so much on healthcare but see worsening chronic disease outcomes?

A: Despite allocating 90% of its $4.5 trillion annual healthcare budget to chronic illnesses, the U.S. continues to see rising rates of conditions like heart disease, diabetes, and cancer. The reason? Most spending goes toward profitable pharmaceutical treatments and surgeries that do not address the underlying cellular dysfunction. Instead of supporting healing, these interventions promote lifelong dependence and fail to reverse disease progression.

Q: How does chronic illness impact patients financially and emotionally?

A: Chronic illness causes severe financial distress, even for those with insurance. Patients with multiple conditions are four times more likely to file for bankruptcy, with average unpaid medical debt rising from $784 (no illness) to $1,252 (multiple conditions).

Beyond finances, patients and their families face intense emotional strain, stress, isolation, and relationship breakdowns. Caregivers, often family members, endure burnout and lost income as they juggle daily care duties.

Q: Why are prescription medications like opioids and antidepressants problematic for chronic conditions?

A: Prescription drugs often become a life sentence rather than a path to healing. Studies show that patients rarely discontinue opioids, even when their pain doesn’t improve, due to increased sensitivity to pain (opioid-induced hyperalgesia).

Similarly, long-term antidepressant use is widespread, with 15.5 million Americans on them for over 5 years, often without reevaluation. Withdrawal symptoms are common and sometimes severe, and polypharmacy worsens overall mental and physical well-being.

Q: What are the “hidden costs” of chronic illness beyond physical symptoms?

A: Chronic illness takes a deep toll on mental, emotional, and social health. Nearly 70% of patients suffer from stress, anxiety, or depression, particularly those with multiple conditions. Social withdrawal, loneliness, and strained marriages and parent-child relationships are common.

The emotional burden also extends to caregivers, who experience fatigue and diminished quality of life. The system’s focus on symptom management, rather than true healing, only worsens these outcomes.

Q: What approach can help me break the cycle of chronic illness and dependence?

A: Healing begins by addressing the root causes at the cellular level. Prioritizing mitochondrial health, adequate glucose intake, reduced exposure to seed oils, and nutrient-rich diets supports the body’s ability to restore itself. This approach moves beyond managing symptoms, aiming instead to rebuild energy production, balance stress hormones, and reduce pharmaceutical reliance — leading to lasting health instead of chronic dependency.

For decades, women suffering from a constellation of baffling symptoms — irregular periods, stubborn weight gain, acne breakouts, thinning scalp hair, unexplained fatigue, mounting anxiety — were handed a diagnosis that often left them more confused than informed: polycystic ovary syndrome (PCOS). The name pointed at their ovaries. Their actual experience pointed everywhere else.

That disconnect is finally being acknowledged. An international team of researchers, working with dozens of medical organizations and thousands of patients, has formally retired the old label. The condition now carries a new name, polyendocrine metabolic ovarian syndrome (PMOS), that reflects what doctors and patients have long suspected: this disorder reaches well beyond the reproductive system, pulling hormone signaling, blood sugar regulation, cardiovascular health, and mental well-being into its grip.

The renaming is more than cosmetic. Patients have spent years bouncing between specialists who treated each symptom in isolation, missing the metabolic engine driving the whole picture. Women without visible cysts were told they did not qualify for the diagnosis. Lean women were dismissed because they didn’t fit the assumed body type.

Adolescents were waved off as hormonal teenagers while damage accumulated. The new framework changes the conversation entirely, and the findings behind it reveal just how interconnected the breakdown really is and why the old name held so many women back from getting help.

Doctors Finally Admit This Condition Wasn’t Just About Ovarian Cysts

Published in The Lancet, an international policy paper brought together 56 medical organizations, patient advocacy groups, and clinical experts from around the world to address a problem patients had complained about for years — the name polycystic ovary syndrome did not describe the disease accurately at all.1 Researchers collected 14,360 survey responses from women with the condition and health professionals across multiple countries and disciplines.

According to the paper, the old name interfered with diagnosis, delayed treatment, and created confusion among both patients and clinicians. Many women spent years chasing isolated symptoms like acne, infertility, or weight gain without realizing they were connected through the same endocrine and metabolic disorder.

Your endocrine system is your body’s hormone messaging network. Your metabolic system controls how you turn food into energy. In PMOS, both systems start malfunctioning together. Researchers specifically noted that the current name “obscur[ed] diverse endocrine and metabolic features” and contributed to fragmented care.

• The study focused heavily on real-world patient experiences — Women with the condition repeatedly described frustration with doctors focusing narrowly on ovarian scans while ignoring fatigue, insulin resistance, depression, cardiovascular risk, and metabolic dysfunction. Researchers explained that the condition affects far more than fertility, yet many women continue to receive symptom management instead of root-cause metabolic care.

• The researchers found overwhelming support for replacing the old name — About 86% of patients and 71% of health professionals supported moving toward a new “accurate name” instead of preserving the PCOS acronym. Patients prioritized stigma reduction while clinicians prioritized scientific accuracy. Both groups agreed the old terminology failed women.

• The new name intentionally highlights multiple hormone systems — Researchers selected “polyendocrine metabolic ovarian syndrome” because it better reflects what actually goes wrong inside the body. “Polyendocrine” means multiple hormone systems malfunction simultaneously. “Metabolic” acknowledges insulin resistance and blood sugar dysfunction. “Ovarian” recognizes reproductive hormone disruption without falsely implying ovarian cysts.

• Experts removed the word cyst because the condition does not actually involve dangerous ovarian cysts — The paper explained that many women diagnosed with the disorder don’t develop pathological cysts at all. Instead, ultrasounds often show many immature follicles — tiny egg-containing sacs that failed to mature normally because hormone signaling became disrupted. Countless women previously believed they did not have the condition if doctors failed to see cysts on imaging.

• The paper revealed how deeply insulin resistance drives the disorder — Researchers reported that insulin resistance affects about 85% of women with PMOS, including approximately 75% of lean women with normal body weight. Insulin resistance means your cells stop responding properly to insulin’s signal to absorb sugar from the bloodstream.

Your pancreas compensates by pumping out more and more insulin, trying to force the message through. Blood sugar may look normal on a standard test for years, even while insulin levels climb.

Elevated insulin levels increase androgen production from the ovaries and adrenal glands. Androgens are commonly called “male hormones,” though women naturally produce them too. When those hormone levels rise too high, women experience facial hair growth, scalp hair thinning, acne, and menstrual disruption.

Metabolic Dysfunction Extends Far Beyond the Ovaries

Insulin resistance increases androgen production, while elevated androgens worsen abdominal fat accumulation and metabolic dysfunction. The result becomes a self-reinforcing cycle. Many women feel trapped because symptoms intensify each other over time instead of staying isolated.

• The paper also linked the disorder to serious long-term disease risk — Researchers described increased rates of obesity, fatty liver disease, Type 2 diabetes, high blood pressure, and unhealthy cholesterol and triglyceride patterns in women with PMOS. Women with PMOS also faced higher odds of composite cardiovascular disease, heart attack, and stroke compared to women without the disorder.

The communication system between your brain and ovaries also becomes dysregulated. Your brain releases hormones in carefully timed pulses, like a metronome keeping rhythm with your ovaries. In PMOS, that rhythm speeds up and distorts, causing the ovaries to overproduce androgens. Androgens drive traits typically associated with male puberty, like body hair, oil production, and muscle development. In women, even modest excesses can reshape the skin, scalp, and menstrual cycle.

• The metabolic damage often starts early — Adolescents can develop the condition during their teenage years, with irregular cycles and androgen excess appearing before major metabolic disease becomes obvious. Researchers explained that adolescents require different diagnostic criteria because ovarian ultrasound findings alone are unreliable during puberty. Many young girls get dismissed as “normal teenagers” while metabolic dysfunction worsens underneath the surface.

• The ovaries themselves become metabolically stressed — Excess insulin damages the specialized cells inside the ovary responsible for ripening eggs and producing estrogen and progesterone in the right amounts. Once disrupted, follicles fail to mature normally, ovulation becomes irregular, and menstrual cycles become unpredictable.

• Inflammation and fat signaling also worsen the condition — Body fat doesn’t just store calories. It also releases chemical signals that influence inflammation, insulin sensitivity, and hormone balance. When abdominal fat accumulates, these signals become distorted and worsen insulin resistance and ovarian dysfunction.

• Mental health complications emerged as another major feature — The paper listed depression, anxiety, eating disorders, and reduced quality of life among the disorder’s broader manifestations.

Many women blamed themselves for symptoms that actually stemmed from underlying hormonal and metabolic disruption. Insulin resistance, inflammation, and disrupted hormone signaling may affect neurotransmitter production and mood regulation, suggesting these mental health symptoms aren’t separate from the metabolic disorder — they’re part of it.

• The renaming strategy includes a three-year transition period — Researchers outlined a coordinated implementation plan involving electronic medical records, global disease coding systems, universities, journals, and clinical guidelines. That gradual transition aims to prevent confusion while helping doctors, researchers, and patients adapt to the new terminology.2

Aligning the name with modern science strives to improve awareness, diagnosis, care quality, patient satisfaction, and research coherence worldwide. For many women, that shift validates what their bodies have been telling them for years. The fatigue wasn’t laziness. The weight wasn’t a willpower problem. The anxiety wasn’t unrelated. They were all signals from the same disrupted system, finally being recognized as such.

Addressing the Metabolic Factors Linked to PMOS

So, if the diagnosis itself has been overhauled, what should women actually do differently? The answer starts upstream of the symptoms at the metabolic level, where the cascade begins. A name change doesn’t alter the underlying hormone and metabolic dysfunction associated with PMOS.

Much of the focus centers on supporting insulin sensitivity, inflammatory response, and healthier communication between your gut, metabolism, and reproductive hormones. Once those systems begin working together again, symptoms may stop spiraling in multiple directions at once.

1. Support your gut environment, which plays a role in hormone balance — Microbiome disruption and intestinal inflammation have both been linked to PMOS. Your gut bacteria influence insulin sensitivity, inflammation, estrogen metabolism, and even ovarian hormone signaling. When that ecosystem becomes damaged, the entire hormonal cascade may start drifting out of balance.

Postbiotics deliver the beneficial compounds your gut bacteria would produce if your microbiome were healthy, skipping the unreliable middle step of trying to recolonize with live bacteria that may or may not survive the journey.3 Unlike probiotics, which contain living bacteria, postbiotics contain the beneficial compounds healthy bacteria produce. Research suggests those compounds may help calm inflammation, support insulin sensitivity, and strengthen the gut barrier.

One of the best-studied options comes from Akkermansia muciniphila, and a sensible starting point is using the pasteurized, postbiotic form. Research suggests that when pasteurized, this bacterium retains a beneficial protein called Amuc_1100 that may help tighten the gut lining and reduce inflammatory stress. Some products are formulated with enteric coating or microencapsulation to survive stomach acid.

Since everyone’s gut is different, it’s worth checking with your health care provider about whether a postbiotic like this is a good fit for you. At the same time, stop feeding the harmful gut species that worsen inflammation. Processed foods, excessive antibiotics, and seed oils keep your microbiome trapped in a stressed state.

2. Rebuild your diet around stable energy production instead of processed convenience foods — PMOS is deeply tied to metabolic dysfunction. That means your food choices directly influence your hormones every single day. Focus on steady blood sugar regulation and cellular energy production instead of extreme dieting. Severe carbohydrate restriction often worsens stress hormones and metabolic dysfunction in the long term. Your body needs carbohydrates to produce energy efficiently.

Start with easier-to-digest whole foods, like fruit and white rice, if your digestion feels compromised with frequent bloating or bowel movement irregularities. Avoid the foods that drive inflammatory overload, including ultraprocessed foods, restaurant meals, and seed oils such as:

• Soybean oil
• Corn oil
• Canola oil
• Sunflower oil
• Cottonseed oil

Linoleic acid (LA) from seed oils can accumulate in tissues and disrupt mitochondrial energy production. Your mitochondria act like microscopic power plants inside your cells. When they struggle to produce energy efficiently, hormone signaling, blood sugar control, and inflammation all worsen. That metabolic stress may worsen the same insulin and hormone dysfunction associated with PMOS symptoms. Replace seed oils with healthier options like grass fed butter, tallow, or ghee.

3. Use movement every day to improve insulin sensitivity naturally — Your muscles become one of your most powerful metabolic tools once you start using them consistently. Daily movement helps improve glucose handling, lower insulin levels, and stabilize hormone signaling. Walking works especially well because it supports blood sugar regulation without overloading your stress response. If your energy feels low or workouts leave you exhausted, start simpler. Aim for:

• About 60 minutes of walking daily
• Strength training two or three times weekly
• Frequent movement throughout the day instead of prolonged sitting

As your muscles use glucose more efficiently, your body stops needing such high insulin output. That lowers one of the major metabolic drivers behind androgen excess and ovarian dysfunction.

4. Lower chronic stress before it keeps disrupting your hormones all day — Your brain and ovaries constantly communicate through hormone signals. Chronic stress can interfere with that communication system and keep cortisol elevated for long stretches of time. When cortisol stays chronically high, insulin resistance worsens, sleep quality drops, cravings intensify, and hormonal rhythms become less stable.

If your schedule feels nonstop, start creating small pockets of nervous system recovery throughout the day instead of waiting for a perfect wellness routine. Helpful strategies include:

• Morning sunlight exposure, which supports mitochondrial energy production and helps regulate circadian rhythms tied directly to hormone balance
• Mindfulness or meditation
• Better sleep timing
• Counseling or emotional processing work
• Reducing excessive screen exposure late at night

5. Reduce the environmental hormone disruptors surrounding you every day — Many women focus only on food while overlooking another major hormonal stressor — environmental xenoestrogens. These are synthetic compounds that mimic estrogen inside your body.

Microplastics act like artificial hormones by binding to estrogen receptors and disrupting normal signaling patterns. That interference may compound the same estrogen-androgen imbalance already driving PMOS symptoms. The following changes help reduce the constant background hormone interference many women experience every day without realizing it.

• Switch to glass food containers
• Avoid plastic water bottles
• Don’t microwave food in plastic
• Choose natural fiber clothing when possible
• Avoid synthetically fragranced personal care products and cleaning supplies

For the millions of women who spent years being told their symptoms were unrelated, the new name is more than terminology. It’s the first formal acknowledgment that what they felt in their bodies was real, connected, and finally addressable.

These findings come from clinical and observational research, including studies of supplements in specific populations. Results may not apply to all individuals.

FAQs About PCOS’ New Name

Q: Why did doctors change the name from PCOS to PMOS?
A: Researchers concluded that the term “polycystic ovary syndrome” misrepresented the condition because many women don’t develop actual ovarian cysts. The new name, polyendocrine metabolic ovarian syndrome, reflects the broader hormone and metabolic dysfunction involved, including insulin resistance, inflammation, and cardiovascular risk.

Q: What symptoms are linked to PMOS?
A: PMOS is associated with irregular menstrual cycles, infertility, acne, facial hair growth, scalp hair thinning, abdominal weight gain, fatigue, anxiety, and insulin resistance. Many women also experience depression, metabolic dysfunction, and chronic inflammation that affect far more than reproductive health.

Q: Why is insulin resistance such a major part of PMOS?
A: The research showed that insulin resistance affects most women with PMOS, including many women who aren’t overweight. Elevated insulin increases androgen production, which worsens acne, irregular ovulation, facial hair growth, and fat accumulation around the abdomen. That creates a self-reinforcing metabolic cycle that intensifies symptoms over time.

Q: How does gut health influence PMOS symptoms?
A: Your gut microbiome helps regulate inflammation, hormone metabolism, and insulin sensitivity. When the microbiome becomes disrupted, hormone signaling also becomes dysregulated. Research suggests postbiotics from beneficial bacteria such as Akkermansia may help strengthen the gut barrier, support insulin sensitivity, and calm inflammatory stress associated with PMOS symptoms.

Q: What lifestyle changes may help address the metabolic factors linked to PMOS?
A: Focus on improving insulin sensitivity and lowering inflammatory stress instead of only on symptom management. Helpful strategies include removing seed oils and ultraprocessed foods, rebuilding tolerance to whole-food carbohydrates, walking daily, adding strength training, reducing chronic stress, and lowering exposure to hormone-disrupting plastics and synthetic chemicals.

Alzheimer’s doesn’t start with forgetfulness — it starts with damage. Long before memory loss appears, your brain begins breaking down at the cellular level. And one of the hidden drivers behind that destruction is something many people don’t think about: iron.

When iron builds up in your brain tissue and reacts with fats and proteins, it causes oxidative stress that destroys neurons from the inside out. This iron-driven process doesn’t just accompany Alzheimer’s — it could be what kicks it into gear. A study from the University of Southern California and the University of California, Irvine uncovered a key clue: people with Down syndrome who develop Alzheimer’s show far more brain iron than those with Alzheimer’s alone.1

That excess iron is tied to brain cell death, inflammation, and early buildup of harmful plaques. If your body can’t safely store and regulate iron, the damage spreads fast — especially in areas tied to memory and executive function. And once your antioxidant defenses are overwhelmed, there’s little left to stop the cascade. Understanding how and why this happens opens the door to new strategies — not just for slowing Alzheimer’s, but for preventing it before it takes hold.

Too Much Iron in Your Brain Speeds Up Alzheimer’s Damage

The study, published in Alzheimer’s & Dementia, looked at how too much iron in your brain drives Alzheimer’s disease, especially in people with both Down syndrome and Alzheimer’s.2 Researchers studied brain tissue from three groups: healthy adults, adults with Alzheimer’s, and adults with Alzheimer’s related to Down syndrome. Their goal was to understand how iron buildup harms brain cells and leads to sticky protein clumps called amyloid plaques, which are tied to Alzheimer’s.

• Iron levels were much higher in people with both Down syndrome and Alzheimer’s — Compared to healthy adults and those with Alzheimer’s alone, people who had both conditions had about twice as much iron in a key brain region responsible for memory and decision-making.

This group had much higher levels of damage from iron reacting with the fats in brain cells and breaking them down. Making matters worse, the natural defenses that protect brain cells from this type of damage were weakened or missing.

• The brain’s protective enzymes were missing where they were needed most — The study found enzymes that normally repair damage to brain cell membranes were reduced by as much as 70% in the affected areas. These enzymes are important because they help prevent brain cell death triggered by iron overload.

Another protective compound, glutathione, also wasn’t being made properly. That’s because the enzyme needed to make it was also reduced by up to 60%. Without enough glutathione, brain cells lose a major line of defense against stress and oxidation.

• Iron harmed key parts of brain cells that act like control centers — The study found that iron was attacking small areas on the cell’s surface where important proteins are handled and messages are sent. In brains affected by Alzheimer’s — especially in people with Down syndrome — these areas were badly damaged. This damage changed how certain proteins were made, increasing the toxic forms that clump together in the brain and destroy nerve cells.

Are Tiny Brain Bleeds the Source of All That Extra Iron?

One major clue came from the discovery of iron deposits in areas linked to microscopic bleeding. These “microbleeds” are tiny leaks from brain blood vessels that often go unnoticed. When blood escapes into brain tissue, it breaks down and releases iron.

Over time, this creates pockets of stored iron that cause more damage. The study found that a cleanup enzyme, which helps process iron from blood, was three times higher in the brains of people with Down syndrome and Alzheimer’s, suggesting chronic bleeding was driving iron overload.

• The brain’s protein-cutting process turned more destructive under stress — Normally, certain brain proteins can be cut in ways that are either safe or harmful. In the damaged brains, the harmful cutting process became more active — not because there was more of the cutting enzyme, but because it was working faster, likely due to iron-related stress. At the same time, the safer cutting process slowed down. This shift caused the brain to make more toxic proteins instead of removing them.

• Even though the body made more antioxidants, they weren’t in the right place — The brain as a whole seemed to increase antioxidant enzyme levels in response to damage, but those enzymes weren’t where they were most needed. This mismatch meant that cells remained vulnerable to damage, even though the body was trying to defend itself. It showed that Alzheimer’s damage isn’t just about overall inflammation or oxidation — it’s about damage happening in precise, high-risk zones.

• Your genes influence how much iron builds up in your brain — In people with rare forms of Down syndrome who didn’t have an extra copy of a certain protein-making gene, there was far less brain iron, fewer harmful protein clumps, and they lived up to 20 years longer than those with the extra gene. This shows that making too much of that protein leads to more iron buildup, more brain damage, and a shorter life — helping explain why some people’s brains decline faster than others.

How to Protect Your Brain from Iron-Driven Damage

High iron is an under-recognized health threat, and there’s a general lack of awareness in the medical community regarding the health risks associated with high iron levels. If you’re concerned about memory loss or have a family history of Alzheimer’s, it’s time to start thinking about iron — not just in your blood, but in your brain.

The study I’ve shared shows that too much brain iron doesn’t just sit there quietly. It ignites a chain reaction of oxidative stress and cell damage that accelerates cognitive decline. Your first move should be reducing the root cause: excess iron accumulation combined with poor antioxidant defenses. Here’s what I recommend to take control of the iron-oxidation cycle and give your brain the support it needs to stay sharp, focused, and protected.

1. Test your ferritin and gamma-glutamyl transpeptidase (GGT) to assess iron burden and oxidative stress — If you don’t know your ferritin level, that’s where you start. Ferritin is the storage form of iron, and the ideal range is between 60 and 75 ng/mL. High ferritin levels indicate your body is holding onto too much iron, which leaks into your brain and triggers damage.

I also recommend asking for a GGT test. GGT is a key marker of oxidative stress and helps identify if free iron is causing damage inside your body. When both ferritin and GGT are elevated, it’s a strong sign your iron is doing harm.

2. Donate blood or request phlebotomy if your iron is too high — If your body is holding onto more iron than it can safely manage, it increases your risk for heart disease, insulin resistance, and oxidative damage to your organs — including your brain. One of the most effective solutions?

Donate blood two to four times a year. This simple act pulls iron out of storage and lowers your levels gradually. If donation isn’t an option due to your health history, ask for therapeutic phlebotomy to achieve the same result.

3. Balance your copper intake to support healthy iron metabolism — Iron reduction is only one piece of the puzzle. If your copper status is low, which is common, your body can’t regulate iron properly. Copper and iron work together. When copper is deficient, iron builds up in places it doesn’t belong. Consider supplementing with 3 to 4 milligrams of copper bisglycinate daily if your intake is low.

You can also focus on copper-rich foods like bee pollen, grass fed beef liver, and acerola cherries — acerola cherry is very high in vitamin C, which contains copper-rich tyrosinase enzyme. Don’t overlook retinol either — this nutrient, found in beef liver and organ meats, helps your body absorb and use copper effectively.

4. Get calcium from food to help keep iron in check — Proper calcium intake reduces your risk of iron overload naturally. When calcium is low, your body produces more parathyroid hormone, which increases iron storage. That creates a feedback loop that worsens brain inflammation over time.

Focus on getting calcium from whole food sources like raw grass fed dairy, pasture-raised egg yolks, and powdered eggshells. Skip the synthetic calcium supplements unless medically necessary, as they don’t offer the same co-factors for absorption.

5. Remove vegetable oils and increase antioxidant-rich foods — Iron is especially dangerous when it reacts with unstable fats, like polyunsaturated fats in vegetable oils. I recommend eliminating canola, soy, corn, sunflower, safflower, and other vegetable oils from your kitchen. These oils break down in your body and feed oxidative stress.

Replace them with stable fats like grass fed butter, ghee, coconut oil, and tallow. At the same time, boost your antioxidant defenses by eating garlic, onions, and pasture-raised eggs. These foods give your body the building blocks to produce glutathione, your brain’s main defense system against iron-triggered damage.

You can also add molecular hydrogen to your daily routine. Hydrogen activates your body’s own healing system by switching on glutathione — especially important when chronic illness and oxidative stress have shut those systems down. Whether through hydrogen-rich water or tablets, this approach helps reactivate your brain’s defense systems where they’re needed most.

By actively lowering excess iron, restoring mineral balance, and strengthening your antioxidant defenses, you protect your brain from the inside out. These steps are simple, actionable, and backed by clear biological mechanisms. Start with testing, make the dietary swaps, and stay consistent — your future brain will thank you.

FAQs About Iron and Alzheimer’s Disease

Q: What does iron have to do with Alzheimer’s disease?
A: Excess iron in your brain causes oxidative damage by reacting with fats and proteins in brain cells. This process leads to neuron death and helps trigger the development of Alzheimer’s. The damage is especially severe in areas responsible for memory and decision-making.

Q: What did the study find about brain iron and Alzheimer’s?
A: The study found that individuals with both Down syndrome and Alzheimer’s had double the brain iron compared to those with Alzheimer’s alone. The extra iron was linked to faster and more severe buildup of brain plaques, greater cell damage from stress, and weaker natural protections in the brain.

Q: Where does all this excess iron come from?
A: Tiny, undetected brain bleeds (microbleeds) appear to be a key source. When blood leaks into brain tissue, iron from hemoglobin is released and stored locally, causing long-term oxidative stress. People with Down syndrome-related Alzheimer’s had a threefold increase in the enzyme that processes blood-derived iron, suggesting chronic internal bleeding contributes to iron buildup.

Q: How can I find out if I have high iron levels?
A: Start by testing your ferritin, the storage form of iron. Ideal levels fall between 60 and 75 ng/mL. You should also request a GGT test to measure oxidative stress. High ferritin and GGT together suggest your body is not safely managing iron, which impacts brain health.

Q: What steps can I take to reduce the risk of iron-driven brain damage?
A: Donate blood regularly or ask for therapeutic phlebotomy if your ferritin is high. Balance iron with copper-rich foods or supplements, increase calcium from whole food sources, eliminate vegetable oils, and boost antioxidants like glutathione. You can also use molecular hydrogen to reactivate antioxidant enzymes and help your brain neutralize oxidative stress.

Metabolic disease is a global epidemic that has become a significant public health problem. Conditions like obesity and Type 2 diabetes are spreading rapidly across populations worldwide, affecting millions and straining health care systems.1 If left unchecked, these diseases can lead to severe complications, including heart disease, stroke, and premature death.

Gut microbiota plays a crucial role in maintaining your health by regulating your body’s metabolism. Among these microorganisms, Akkermansia muciniphila stands out as a key player. Research suggests Akkermansia plays a role in metabolic and immune functions and may support gut health.2 Low levels of this bacterium have also been linked to an increased risk of a variety of diseases, including intestinal inflammatory diseases and certain parasitic infections.3

Current research highlights the importance of Akkermansia in managing a wide variety of these conditions. For instance, studies published inFrontiers in Immunology and Frontiers in Microbiomes have shown that alterations in Akkermansia abundance are associated with the severity of metabolic disorders and immune-related diseases.4,5

Additionally, research in Critical Reviews in Microbiology and Microbiome Research Reports has explored its role in gut health and its potential as a therapeutic target in ongoing research.6,7,8

Exploring the Benefits of Akkermansia Muciniphila

Low levels of Akkermansia are associated with metabolic diseases such as obesity and Type 2 diabetes. Conventional treatments for these conditions typically involve medications that can have deleterious side effects. For instance, drugs like metformin, commonly prescribed for diabetes, may cause gastrointestinal issues and vitamin B12 deficiency.

• Weight-loss medications like Ozempic are also associated with serious side effects — These include pancreatitis, bowel obstruction, stomach paralysis, and even death. The problem is that these conventional treatments address symptoms rather than the root causes. Researchers are now exploring holistic strategies, and one angle they’re looking into is Akkermansia supplementation, which may play a role in supporting metabolic health.
• The underlying causes of metabolic diseases are multifaceted — They often stem from a combination of genetic predisposition, poor dietary habits, sedentary lifestyles, and environmental factors. High intake of ultraprocessed foods loaded with refined sugar and polyunsaturated fats (PUFs), coupled with low physical activity, lead to obesity, which is a major risk factor for Type 2 diabetes.

Chronic inflammation and insulin resistance — measured by markers such as homeostatic model assessment of insulin resistance (HOMA-IR) — also play crucial roles in the development of these conditions.

Research Explores Akkermansia’s Role in Supporting Metabolic Health

A 2024 Chinese review published in Frontiers in Immunology explored the potential of Akkermansia muciniphila as a probiotic for metabolic conditions and overall human health.9 The researchers investigated how it affects gut microbiota, immune function, and various metabolic processes that are relevant in conditions like obesity, Type 2 diabetes, cardiovascular disease, and fatty liver disease.10*

• Akkermansia makes up about 1% to 4% of the total intestinal microbiota in the human gut — Analyzing data from numerous experiments, the researchers reported a consistent pattern: individuals with lower levels of Akkermansia in their gut microbiota were more likely to have severe metabolic conditions.
Human and animal studies have also reported improvements in metabolic markers in subjects who received Akkermansia, though the published human trials are small, proof-of-concept studies.

In a Nature Medicine 2019 proof-of-concept trial involving 32 overweight/obese volunteers, participants receiving pasteurized Akkermansia for three months showed reductions in body weight, fat mass, and hip circumference compared to placebo, and improved insulin sensitivity.11*

• Akkermansia has also been associated with enhanced gut barrier function — This means it may help reduce the passage of harmful substances into the bloodstream, thereby reducing inflammation. Continuing this line of thought, inflammation is recognized as a contributor to insulin resistance, and researchers are exploring whether Akkermansia’s anti-inflammatory effects may influence Type 2 diabetes-related markers.
In addition, animal research has reported that Akkermansia may attenuate Western diet-induced atherosclerosis (in mouse models), prompting interest in its relationship to cardiovascular health.*

*These findings are from research conducted in clinical settings. Results may not apply to all individuals.

Mechanisms of Action

According to the authors, the proposed mechanisms of action vary by condition.12 In animal models of obesity, pasteurized Akkermansia has been reported to reduce carbohydrate absorption and increase energy excretion through feces, and to inhibit adipocyte (fat cell) formation. In Type 2 diabetes models, Akkermansia has been observed to stimulate GLP-1 secretion and influence insulin production.

GLP-1 is a hormone naturally produced in your intestines that plays a crucial role in blood sugar regulation and appetite control. When released after eating, it stimulates insulin production from the pancreas while suppressing glucagon, helps slow down stomach emptying to promote feelings of fullness, and acts on the appetite centers in your brain to reduce hunger.

It also supports the growth of insulin-producing beta cells in your pancreas and has been associated with cardiovascular benefits in research settings.

In animal models of fatty liver disease, Akkermansia has been reported to support hepatic (liver) fat metabolism. Researchers observed an increase in L-aspartate, which is associated with a metabolic chain reaction that may help reduce hepatic fat storage.

Dosages Used in Metabolic Studies

The following dosages are from animal (mouse) studies and are presented for research context only. They range from 100 million to 200 million colony forming units (CFUs) depending on the condition:†

1. Type 2 diabetes — 200 million CFUs per day (2 × 108 CFU/0.2 mL) administered for four weeks in mice on high-fat diets with researchers observing reduced blood glucose levels.13
2. Cardiovascular disease — 200 million CFUs (2 × 108 CFU/180 μL) in mouse models examining cardiovascular outcomes through effects on gut microbiota and immune function.14
3. Fatty liver disease — 100 million CFUs per day (1 × 108 CFU/mL) administered for six weeks in mice on high-fat/cholesterol diets, with reported reductions in liver steatosis, inflammation, and injury reported.15

†These findings are from laboratory or animal research and may not directly apply to human health.

In human trials, dosages up to 10 billion CFUs have been studied. As mentioned earlier, a three-month proof-of-concept clinical trial tested Akkermansia supplementation in 32 overweight and obese volunteers, using either live Akkermansia (10 billion CFU/day) or pasteurized Akkermansia (30 billion total fluorescent units (TFU)/day).16

• Both forms were safe and well-tolerated — Digging deeper into the data, the pasteurized form was associated with greater improvements in insulin sensitivity, insulinemia, total cholesterol, body weight, fat mass, and hip circumference compared to placebo. The pasteurized form was also associated with decreased white blood cell counts and inflammation markers like LPS. Larger trials are needed though to confirm these findings.
• Additional evidence reporting the safety profile of Akkermansia — In another 12-week proof-of-concept study of overweight and obese subjects with insulin resistance and metabolic syndrome, administration of Akkermansia (at doses of 1 or 10 billion CFU, either live or pasteurized) was associated with distinct changes in fasting plasma metabolites compared to the control group.17

Here, researchers observed several outcomes: improvements in blood lipid markers, glycemic indicators including HOMA-IR-measured insulin resistance, hepatic enzyme levels, and endotoxemia markers. They also noted promising trends in obesity-related body measurements.

Probiotic Potency Explained: CFU, AFU, and TFU

When evaluating the potency of probiotics, there are three units of measurement you need to be aware of: colony forming units (CFU), active fluorescent units (AFU), and total fluorescent units (TFU).

• Colony forming units (CFU) — This is the most widely recognized and utilized metric for quantifying the number of viable bacteria or fungal cells in a probiotic product. One CFU represents a single microorganism capable of dividing and forming a colony under specific laboratory conditions. This measure is important because the activity of probiotics is associated with the number of live microorganisms that reach your gut.
Probiotic manufacturers typically list CFU counts on product labels, indicating the number of live organisms per serving. Higher CFU counts are often marketed as more potent, though the optimal CFU level can vary depending on the specific strains and the health context.
Consumers are also advised to check that the CFU amount listed on the label is specified as the CFU level at the end of shelf life (its expiration date).18 As noted by The Probiotics Institute,19 “The amount of probiotic (CFU) present on the ‘manufacturing date’ is not as important as the amount present at the ‘end of shelf life.'”
• Active fluorescent units (AFU) — This unit is a less conventional and not widely standardized measure in the context of probiotics, with the exception of Akkermansia. While CFU shows the number of bacteria that are alive, AFU refers to the total number of bacteria present, both dead and alive. It is primarily a unit used to measure enzymatic activity.
For instance, AFU could be used to evaluate the activity levels of specific enzymes produced by probiotics, which contribute to their function, such as breaking down lactose or producing vitamins. In some specialized applications, AFU is also used to assess the metabolic activity or functional potency of probiotic strains beyond mere viability.
Most companies that sell Akkermansia probiotics use AFU instead of CFU, and there’s a scientific reason for that. Akkermansia is a strict anaerobe and as such it plate-counts poorly under standard probiotic quality control conditions. Many viable-but-non-culturable (VBNC) cells aren’t captured by CFU even though they’re metabolically active.
Flow cytometry (AFU) was developed in part to address this conundrum. It labels cells with fluorescent dyes that distinguish intact membranes (live) from compromised ones, and counts each cell as it passes through a laser. In short, flow cytometry captures VBNC cells that plate counts miss.
• Total fluorescent units (TFU) — This unit measures the total bacterial mass including both live and dead cells through fluorescent labeling, and is typically used only for pasteurized products. Like AFU, TFU values are higher than CFU counts for the same sample since they include both viable and non-viable cells.

The primary difference between CFU, AFU, and TFU lies in what they measure: CFU quantifies the number of live microorganisms; AFU assesses the functional activity of those microorganisms; and TFU measures the total bacterial mass, regardless of their functional activity. While CFU is an indicator of the potential for colonization and survival of probiotics in the gut, AFU could offer additional insights into the functional capabilities of the probiotic strains.

Akkermansia’s Role in Brain Function

Akkermansia has also been studied for its interactions with brain function through the gut-brain axis. A comprehensive review published in the journal Critical Reviews in Microbiology explored the bacterium’s relationship with various neuropsychiatric conditions, documenting distinct patterns of abundance across different disorders.20 For example, research has reported reduced levels of Akkermansia in depression, anxiety, Alzheimer’s disease, substance use disorders, and ALS.

In Alzheimer’s disease research, patients tended to have reduced levels of Akkermansia, and supplementation has been studied across multiple preclinical models. For example, in Alzheimer’s mouse models, researchers observed reduced Aβ40 and Aβ42 levels — isoforms of amyloid beta peptide implicated in the disease — in the cerebral cortex, along with improvements in spatial learning and memory.

The supplementation also influenced brain measures at a cellular level in mouse studies, reducing microgliosis — the activation and proliferation of microglia (the brain’s immune cells) in response to injury or inflammation. Akkermansia also lowered inflammatory cytokines in the hippocampus, supporting oxidative metabolic activity, and restoring mitochondrial enzyme function.

How Akkermansia Can Support Brain Health

According to the Critical Reviews in Microbiology paper,21 research suggests Akkermansia may influence brain function through three proposed mechanisms:

• It may help protect the intestinal barrier — Akkermansia does this by increasing mucus-producing goblet cells, enhancing tight-junction proteins, and regulating endocannabinoid system molecules and GLP-1/GLP-2. These actions are thought to collectively reduce intestinal permeability and strengthen barrier function.
• Akkermansia aids in producing important metabolites — These include short-chain fatty acids (specifically propionate, acetate, and isovaleric acid) and may influence amino acid metabolism that affects neurotransmitters like GABA and serotonin. It has also been linked to hormones, dopamine, and brain-derived neurotrophic factor (BDNF) levels. Research has reported correlations between Akkermansia abundance and Alzheimer’s disease biomarkers through these metabolic pathways.
• Akkermansia appears to modulate the immune system by reducing inflammatory infiltration and proinflammatory cytokines (TNF-α, IL1α, IL6, IL12A) — At the same time, it increases anti-inflammatory macrophages and regulatory T cells. It also upregulates IL-10 expression, which in turn reduces transcription of pro-inflammatory cytokines.
In terms of brain-specific immune effects, there is also limited evidence suggesting it may help prevent high-fat diet-induced microgliosis in the hippocampus.

However, the paper emphasizes that while these mechanisms show promise, many aspects remain unclear. Most hypotheses about Akkermansia’s effects on brain function are based on its documented impacts on intestinal barrier protection, immune modulation, and metabolite production rather than direct evidence. Additional research, particularly human studies, is needed to fully understand its therapeutic potential for neuropsychiatric disorders.

Akkermansia in Intestinal-Related Diseases

Akkermansia is also being researched for its role in supporting intestinal health, with implications for certain intestinal conditions, according to a 2024 Microbiome Research Reports review.22 As in the other studies discussed, one of the standout findings was that Akkermansia is associated with improved gut barrier function.

• The gut barrier acts like a protective wall lining your intestines — This can help prevent harmful substances from leaking into your bloodstream. Research suggests that strengthening it may reduce inflammation and support resistance to certain infections — factors that are relevant in inflammatory bowel disease (IBD) research.23

According to the cited paper, Akkermansia operates through several interconnected mechanisms. In terms of microbiota regulation, it produces short-chain fatty acids like acetate and propionate while supporting the growth of beneficial butyrate-producing bacteria. Researchers have also reported that it reshapes the gut microbial community by inhibiting harmful bacteria like Salmonella pullorum while promoting beneficial species.

• Research associates Akkermansia with enhanced barrier function through multiple pathways — For starters, it increases the expression of tight junction proteins and supports both mucus production and antimicrobial peptide expression. It also stimulates intestinal barrier protein production and upregulates specific proteins that maintain the structural integrity of the intestinal barrier.
• Immune system modulation is another proposed mechanism — As mentioned in the previous section, Akkermansia has been reported to reduce pro-inflammatory cytokines and increasing anti-inflammatory cytokines. It also has effects on T cell responses, particularly cytotoxic T lymphocytes (CTLs), and influences both dendritic cell and macrophage function.

These relationships are important. By influencing T cells (which fight infections and cancer), dendritic cells (which help identify threats), and macrophages (which eliminate harmful substances), Akkermansia is thought to help maintain balanced immune responses. This modulation may affect how well your body responds to threats while supporting against excessive inflammation that could damage healthy tissue.

Akkermansia May Have a Unique Role in Stress Management

Last but not least, Akkermansia supplementation has been studied in the context of stress-related conditions. A scientific review published in the September 2024 issue of Microbiome Research Reports investigated how Akkermansia interacts with the body to support mental health and assessed its activity in stress management.24

Although the research did not specify a particular study population, it provides insights into the potential applications of this bacterium.

As noted in this paper, animal research suggests that Akkermansia may reduce stress-related behaviors through several proposed mechanisms involving the microbiota-gut-brain axis, including the upregulation of BDNF. For context, BDNF is a protein that supports the survival and growth of neurons in the brain, essential for learning and memory.

Higher levels of BDNF have been associated with reduced symptoms of depression and improved cognitive function in research. Through its connection with BDNF, Akkermansia may support neuronal health and stress resilience, according to current published data.

Akkermansia also produces extracellular vesicles (EVs) that can interact with the host gut epithelium and may have biological activity comparable to whole bacterial cells. EVs are tiny particles released by cells that can transfer proteins and genetic material to other cells, and the EVs produced by Akkermansia have been observed in research to induce central nervous system-linked effects.

Here’s a summary of four studies examining Akkermansia effects on different neurological and stress conditions in mouse models,†† and the dosages used:25

• Depression with colitis — 1 billion CFUs per mL (1 × 109 CFU/mL) via fecal microbiota transplantation after antibiotic treatment in mice with chronic restraint stress and colitis. Researchers observed improvements in behavioral tests measuring depression-like symptoms (open field, tail suspension, and forced swim tests).
• Chronic stress effects — 500 million CFUs per mL (5 × 108 CFU/mL) orally for three weeks in stressed mice. Results showed improved behavioral test scores, reduced stress hormone levels, increased dopamine and BDNF, and changes in gut microbiota.
• Depression with alcohol exposure — 2.5 billion CFUs per 200 μL (2.5 × 109 CFU/200 μL) orally for five weeks in mice exposed to chronic stress and alcohol. Improvements were observed in body weight, depression-like behavior, and sucrose preference.
• Antibiotic-induced depression — Mice treated with antibiotics were given 1.5 billion CFUs per 200 μL (1.5 × 109 CFU/200 μL) daily for two weeks. Results showed reduction in depression-like behaviors caused by the antibiotic treatment.

How Research Suggests You Can Support Akkermansia Levels

One area researchers have studied is whether dietary patterns can shift Akkermansia abundance. As reported in Frontiers of Immunology:26

“Supplementation with prebiotics, fructo-oligosaccharides, FODMAP (fermentable Oligo-, Di- and Mono-saccharides and Polyols — which includes fructose, lactose, oligosaccharides, polyols, and sugar alcohols (polyols, such as sorbitol, mannitol, xylitol, and maltitol)), and dietary polyphenols may increase the abundance of Akkermansia in healthy humans or animals. In addition, prebiotics can reverse the reduction of Akkermansia abundance due to high-sugar or high-fat diets.”

Pasteurized Akkermansia postbiotics and live Akkermansia supplements are another area of research and clinical use. Based on the published evidence (see Nature Medicine 2019 and Gut Microbes 2021 cited earlier), research has used live Akkermansia at 1 billion to 10 billion CFUs per day in human studies, with the pasteurized form showing greater associated benefit in the published proof-of-concept trial. That said, I recommend a two-phase approach:

• Phase 1 (Pasteurized Akkermansia postbiotics) — Postbiotics are non-living bacterial components that still deliver biological signals. Pasteurized forms of Akkermansia muciniphila contain Amuc_1100, a protein associated with tightening the gut barrier and reducing inflammation in research.
Look for postbiotic formulas with enteric coating or microencapsulation so the active components survive stomach acid and reach the colon intact. Without that protection, very little Amuc_1100 reaches the colon, and megadosing to compensate is expensive and inefficient — coated formats are more practical.
• Phase 2 (Live Akkermansia) — Introduce live probiotic Akkermansia only after all of the following: bloating remains minimal or absent; stool form stays consistent for at least seven days; fiber tolerance expands without symptom return. At this stage, live Akkermansia may be introduced alongside gentle prebiotics — like small amounts of resistant starch — to support the growth of butyrate-producing strains.

In closing, growing evidence suggests Akkermansia muciniphila may have implications for multiple aspects of health.

Keep in mind that the research findings are not universal, and individual responses may likely vary. My team is developing an affordable test to analyze your gut microbiome, with specific focus on Akkermansia. With that baseline, your health care practitioner will be able to make better-informed recommendations about whether Akkermansia augmentation might be appropriate for your specific condition.***

FAQs About Akkermansia Muciniphila

Q: What is Akkermansia muciniphila, and why is it important for gut health?
A: Akkermansia muciniphila is a bacterial species that resides in the mucus layer of the human intestinal tract, where research suggests it plays a role in supporting the gut barrier. It typically makes up roughly 1% to 4% of the gut microbiota. Studies have associated higher levels of Akkermansia with various markers of metabolic and intestinal health, though most direct mechanistic evidence comes from animal models, and larger human studies are still emerging.

Q: What does the research say about pasteurized versus live Akkermansia?
A: In a 2019 proof-of-concept human trial published in Nature Medicine that involved 32 overweight or obese adults for three months, pasteurized Akkermansia was associated with greater improvements in insulin sensitivity and several metabolic markers compared to live Akkermansia or placebo.
You can follow a two-phase approach: starting with pasteurized Akkermansia postbiotics (which retain the Amuc_1100 protein associated with gut barrier function) before introducing live Akkermansia once gut tolerance is established. Larger trials are still needed to confirm these findings.

Q: What dietary approaches may support Akkermansia levels?
A: Diets high in refined sugar and seed-oil-derived polyunsaturated fats have been associated with reduced Akkermansia levels in research. For most adults working to restore gut function, the first-step approach is white rice and whole fruits rather than high-fiber or extensive prebiotic interventions, because fiber can increase endotoxin load in a compromised gut. As always, dietary changes need to be made with attention to individual tolerance and in consultation with a qualified health care provider.

Q: Is Akkermansia supplementation safe?
A: In the published human trials to date (see Nature Medicine 2019 and Gut Microbes 2021 in the article), both live and pasteurized Akkermansia were reported as safe and well-tolerated over the three-month study periods. However, these were proof-of-concept studies with small participant numbers, and longer-term safety data are still emerging. Talk to your health care provider before beginning any new supplement, particularly if you have a medical condition or take medications.

Q: How does Akkermansia interact with the gut-brain axis?
A: Research has explored several proposed mechanisms by which Akkermansia may influence brain function — including supporting the intestinal barrier, producing short-chain fatty acids, and modulating immune signaling that interacts with the central nervous system.
Studies have observed associations between Akkermansia levels and markers in conditions such as depression, anxiety, and Alzheimer’s, though most direct mechanistic evidence comes from mouse models. Larger human studies are needed.
