Visualize a huge workshop in your body that never stops working. Every second of the day, this workshop — your cells — transforms the food you eat into the energy and building blocks you need to survive. Picture endless supplies of raw materials being delivered to this workshop. When the workshop receives exactly what it needs, it hums along smoothly, producing vital components and discarding waste at a comfortable pace.

But when it is flooded with more resources than it can handle, chaos develops that reminds you of an old “I Love Lucy” episode. Conveyor belts clog, half-finished products pile up, and machines begin malfunctioning. That chaos mirrors what happens inside your cells when blood sugar stays chronically high, as it does in Type 2 diabetes.

Scientists once focused on how too much sugar in your bloodstream creates damage through something called oxidative stress — an onslaught of destructive, oxygen-containing molecules. While that is important, a less-discussed process — reductive stress — may be at least as central to the damage.1 For an easy-to-understand overview of what reductive stress is, and how it’s caused, see “Redox Simplified, Part 1.”

Reductive stress was described in the literature as early as 1989 — in a study of hepatocytes under chemical hypoxia — and has only relatively recently been applied to chronic high blood sugar.2 It is at least as significant as oxidative stress for explaining why your cells lose their balance under conditions of prolonged high blood sugar. Reductive stress is proposed to be the hidden spark that sets off a harmful chain reaction, one that may eventually contribute to problems for cells, tissues, and organs.

Type 2 diabetes is frequently described as a disease of “overnutrition.” People consume more caloric energy than their bodies know what to do with, so cells try to cope with that oversupply. Insulin is the hormone that helps move sugar from the bloodstream into cells for use or storage.

This sugar is primarily glucose — a simple sugar that is chemically identical to what’s sometimes called dextrose, especially when you find it as a commercially available product in a store or used in intravenous lines (IVs). In the early stages of Type 2 diabetes, cells grow resistant to insulin’s signal, making them slow to remove excess sugar from circulation.

However, in the late 1980s, scientists began to understand that there was another, more significant explanation beyond overnutrition. They couldn’t fully explain the observed pathologies solely based on excessive nutrient intake.

While overnutrition can contribute to health problems, the deeper issue appears to be a disruption in the cellular machinery responsible for metabolizing fuel. Essentially, the “furnaces” within cells, the mitochondria, become less efficient at burning fuel. This diminished capacity to use fuel effectively leads to a buildup of harmful byproducts and, ultimately, cellular damage.

Why Overly High Sugar Leads to Reductive Stress

Many researchers once blamed only oxidative stress for the damage caused by chronic elevated blood sugars, but the story is far more complex. A less publicized culprit called reductive stress occurs when there is an oversupply of special electron-carrying molecules in your cells.

• Too many electron-carrying molecules in your cells — One of the key carriers is nicotinamide adenine dinucleotide (NADH), which picks up electrons when sugar is broken down for energy. Ordinarily, NADH unloads its electrons in the electron transport chain (ETC) of your mitochondria. When you have too much sugar around, your metabolic pathways generate more NADH than your cells can handle. This oversupply forms a traffic jam of electrons stuck in your mitochondrial ETC.

• The impact of excess NADH — During normal metabolism, oxygen in your mitochondria eventually accepts electrons from carriers like NADH, letting adenosine triphosphate (ATP) and water form. However, if NADH is piling up too fast or is not being recycled quickly enough, your mitochondria reach a bottleneck and start leaking electrons onto oxygen in erratic ways. That partial reaction creates a reactive oxygen species (ROS) called superoxide.

• Having excess NADH can cause reductive stress — This is thought to set off a cascade that leads to excessive oxidative stress. The two stresses work hand in hand — they both push the system toward an oxidative meltdown. Realizing that they are connected helps explain many of the complications tied to long-term high blood sugar.

Cells also have backup systems like NADPH, which help defend against or repair routine oxidative damage. But when you have high blood sugar, these carriers are also thrown off balance, sometimes contributing further to reductive stress. So, what should be a finely tuned assembly line of electrons becomes a crowded, poorly managed factory.

How Mitochondria and Enzymes Suffer Under Excess Sugar

Under healthy conditions, most sugar flows through glycolysis and then the Krebs cycle in your mitochondria, leading to a steady generation of NADH for ATP production. In a state of chronically high blood sugar, a steady flood of sugar pours in, leading to overly high rates of NADH production.

• Influx of sugar creates electron pressure — Pancreatic beta cells and liver cells are particularly vulnerable because they possess an enzyme called glucokinase, which does not slow down as sugar accumulates. It just keeps stuffing sugar into the mill, generating more pyruvate and acetyl-CoA, and eventually too much NADH.

This leads to what some researchers call electron pressure. Think of it as building water pressure in a dam. The more NADH, the more “water” is pushing against the gates of the ETC. If the gates can’t relieve that pressure quickly enough, water (electrons) spills out in harmful ways, forming superoxide and other ROS.

• Rethinking the accepted causes of oxidative stress — Though fat metabolism or a lack of antioxidants is typically considered the reasons for oxidative stress, this featured review argues that an overabundance of electron carriers such as NADH is what triggers the chain of events.

• Low oxygen consumption occurs — Low oxygen usage in cells, sometimes referred to as pseudohypoxia, can also happen under these conditions. Even though oxygen might be physically present, the cell’s ability to use that oxygen effectively stalls when electron carriers accumulate. It’s the same effect as having enough workers on an assembly line but not being able to move products forward because the packaging stations are jammed.

When Reductive Stress Morphs Into Oxidative Damage

Too much NADH sets the stage for oxidative stress, but how does that transition really happen?

• The process behind excess NADH creation — The mitochondria’s Complex I tries to oxidize NADH — basically convert it back to NAD+ — but an overwhelming influx of NADH leads to partial electron leaks onto oxygen, generating superoxide.

• Superoxide transforms into more harmful substances — The superoxide easily transforms into other even more hazardous molecules, such as hydrogen peroxide or hydroxyl radicals, intensifying the cell’s damage. Hence, reductive stress is proposed to be the fuse that ignites oxidative stress.

Researchers used to think of oxidative stress and reductive stress as opposites, but this review makes the case that a large wave of oxidative molecules generally follows an upstream buildup of electrons. The meltdown occurs when all these unwanted oxygen-based molecules assault proteins, lipids, and genetic material within cells, blocking regular functions and straining the system further.

How Key Enzymes Become Blocked, Triggering Toxic Side Routes

Glyceraldehyde 3-phosphate dehydrogenase, or GAPDH, is an important enzyme in glycolysis. You can think of it as a traffic cop, directing the flow of carbon units down the main route for energy production.

• Reductive stress roadblocks GAPDH — In reductive stress conditions, superoxide and other reactive molecules can chemically inactivate GAPDH, jamming the normal route. That means partially digested sugar fragments accumulate, searching for an escape route. If the main road of glycolysis is blocked, these fragments slip into alternative pathways — often called branching pathways.

• Examples of branching pathways — One of the branches is the polyol pathway, where sugar is first turned into sorbitol and then into fructose. This route increases NADH and drains NADPH, leaving the cell less capable of defending against oxidative threats. Another branch is the hexosamine pathway, which decorates proteins with sugar-like attachments and can promote even more harmful byproducts.

A third branch leads to the creation of advanced glycation end products, lumps of sugar stuck onto proteins that distort them and spark inflammation.

Each of these side roads is linked to the production or amplification of ROS, so the cell can find itself in an escalating cycle — high sugar contributing to reductive stress, which can add to oxidative stress. This damages enzymes, diverting leftover sugar into alternative routes that generate still more oxidative stress.

• Where diabetic complications may come from — This cyclical process is proposed to underlie the hallmark problems of diabetes — nerves lose function (neuropathy), eyes develop vision problems (retinopathy), kidneys are damaged (nephropathy), and blood vessels narrow or weaken (contributing to strokes, heart attacks, and amputations). It’s a chain reaction that the review traces back to too much sugar and too many electrons in the wrong place at the wrong time.

The following graph, Figure 4 from Liang-Jun Yan’s 2014 review article, “Pathogenesis of chronic hyperglycemia: from reductive stress to oxidative stress,”3 published in the Journal of Diabetes Research, illustrates this proposed process.

It is worth noting what kind of paper this is — a narrative review that synthesizes laboratory and animal findings into a proposed mechanism, rather than a clinical trial in people. The pathway it describes is a well-argued hypothesis, not a demonstrated cause-and-effect sequence in human patients.

What This May Mean for People with Diabetes

As chronic hyperglycemia persists, cells get battered by waves of destructive molecules. This environment disrupts insulin secretion, lowers insulin sensitivity, and robs tissues of normal functioning. Studies measuring oxidative stress markers have reported higher levels in people with poor blood sugar control, a pattern consistent with — though not proof of — the idea that excess electron carriers translate into oxidative harm.

• There is a glimmer of hope — If the fundamental problem is that NADH builds up too fast, then reducing or balancing that electron overload might help limit the downstream damage.

• Looking further upstream — While many diabetes treatments focus on lowering blood sugar in general, or on clearing ROS after they form, researchers have suggested that approaches which curb the production of extra NADH, or help cells recycle NADH back to NAD+ more efficiently, deserve further study.

• Other directions under investigation — Some researchers suggest that strengthening the ETC, or using dietary or pharmaceutical interventions that enhance NAD+ regeneration, may short-circuit the cascade before oxidative stress escalates.

In simpler language, controlling reductive stress means improving the traffic flow of electrons in the cell, ensuring they don’t stack up to dangerous levels. If you manage the electron flow at the front end, you reduce the chance of harmful chain reactions downstream.

Putting It All Together — Why Reductive Stress Matters So Much

Prolonged high blood sugar is well-documented as toxic to cells, but the featured review proposes that the toxicity operates through a two-phase process — first, reductive stress (an electron overload), then oxidative stress (excess oxygen-based radicals) completing the damage.

• Oxidative stress is just one piece of the puzzle — The statement above modifies the classic narrative that only oxidative stress is to blame. Recognizing how reductive stress kindles oxidative stress helps us see that lowering sugar might not be enough; we also need to keep watch on the entire electron-handling machinery within cells.

• Reductive stress needs to be detected earlier — One of the big questions is why reductive stress has been overlooked for so long if it’s so central. Part of the answer is that oxidative stress is easier to detect with standard lab tests and known chemical markers, whereas reductive stress is more subtle, only revealing itself in how the electron carriers build up.

Also, reductive stress was first documented decades ago and then largely forgotten, overshadowed by the simpler story of oxygen-based radicals. Only with improved technologies and a deeper dive into ETC dynamics did researchers rediscover how an oversupply of NADH or NADPH can disrupt everything.

In everyday life, the main message remains consistent — support healthy blood sugar regulation, and give your mitochondria what they need to process fuel efficiently in the first place.

• Strategies to address reductive stress — Good nutrition, regular movement, and routine medical check-ups all form part of the frontline in keeping reductive stress from escalating into widespread oxidative damage.

• The importance of studying reductive stress — Long term, the real advantage in understanding reductive stress is that it offers a new angle — one that goes beyond the usual talk of high sugar and ROS. By focusing on the earliest link in the chain, researchers hope that several downstream problems might be addressed at once — a possibility the featured review raises for insulin production, inflammation and organ function, though it remains to be tested.

Supplements That May Help Address Reductive Stress

Several nutrients have been discussed in the research literature in connection with mitochondrial electron flow. It is important to be clear about what that does and does not mean — none of these have been tested as a treatment for reductive stress in people with Type 2 diabetes, and the featured review cited above does not evaluate any of them. What follows is a summary of proposed mechanisms; it’s not a treatment protocol:

• Coenzyme Q10 (CoQ10) / Ubiquinol:

◦ Mechanism — CoQ10 is a vital component of the ETC in mitochondria. It acts as an electron shuttle, helping to move electrons along the ETC and facilitate ATP production. In its reduced form, ubiquinol, it can also act as an antioxidant.

◦ Relevance to reductive stress — Because of its role in the ETC, CoQ10 has been proposed to influence NADH handling and electron leakage.

• Alpha-lipoic acid (ALA):

◦ Mechanism — ALA is a potent antioxidant that can also regenerate other antioxidants, such as vitamin C. It also plays a role in mitochondrial energy metabolism.

◦ Relevance to reductive stress — ALA’s antioxidant properties have been discussed in relation to the oxidative damage that follows reductive stress. Worth noting, though — adding reducing equivalents is a different strategy from relieving the electron overload described earlier in this article, and the featured Journal of Diabetes Research review cited earlier points toward improving NADH oxidation rather than adding antioxidants.

◦ Note — ALA exists in two forms (R-lipoic acid and S-lipoic acid), and the R form is generally considered more biologically active.

• Methylene blue:

◦ Mechanism — Methylene blue acts as an alternative electron acceptor in the ETC, effectively bypassing Complex I and III. It can cycle between its oxidized and reduced forms, shuttling electrons directly to cytochrome c and oxygen, improving mitochondrial function even when the standard ETC is impaired.

Methylene blue’s ability to accept electrons makes it particularly useful in conditions where the standard ETC is overwhelmed or dysfunctional.

◦ Relevance to reductive stress — By providing an alternative route for electron flow, methylene blue helps relieve the electron congestion that characterizes reductive stress. It effectively acts as an “electron pressure release valve,” helping to prevent the buildup of NADH and reducing the likelihood of electron leakage and subsequent oxidative damage.

◦ Important safety parameters — If you are considering methylene blue, use only pharmaceutical-grade methylene blue in capsule or tablet form, prescribed by a health care professional and sourced from a compounding pharmacy. The dose typically discussed for reductive stress is 5 milligrams once daily, regardless of body weight. Industrial or aquarium-grade methylene blue is not suitable for human use.

• Pyrroloquinoline quinone (PQQ):

◦ Mechanism — PQQ is a potent antioxidant that has been reported in laboratory and animal research to stimulate mitochondrial biogenesis (the creation of new mitochondria).*

◦ Relevance to reductive stress — If PQQ does increase the number of mitochondria and improve their function, it could in principle expand the cell’s capacity to handle electron flow. This has not been tested against reductive stress in people.

• Riboflavin (B2), niacinamide (B3) and thiamine (B1):

◦ Mechanism — B vitamins play essential roles as coenzymes in various metabolic pathways, including those involved in energy production and the ETC. Riboflavin is a precursor to FAD, and niacinamide is a precursor to NAD+. Both are electron carriers.

◦ Relevance to reductive stress — Adequate levels of B vitamins are essential for the proper functioning of the ETC and may help to prevent the buildup of reducing equivalents.

Frequently Asked Questions (FAQs) on Reductive Stress and Type 2 Diabetes

Q: What is reductive stress, and how does it relate to Type 2 diabetes?

A: Reductive stress occurs when cells accumulate too many electron-carrying molecules, such as NADH, due to prolonged high blood sugar levels. This overload creates a bottleneck in the mitochondria, leading to an imbalance that ultimately triggers oxidative stress. In Type 2 diabetes, more fuel arrives than the cell’s machinery can process, and this overload is proposed to set off a cascade of effects that may damage cells, tissues, and organs.

Q: How does reductive stress contribute to oxidative stress and cellular damage?

A: When NADH builds up in cells, it overwhelms the electron transport chain (ETC) in mitochondria, leading to electron leakage. These leaked electrons react with oxygen to form harmful reactive oxygen species (ROS) like superoxide and hydrogen peroxide. This oxidative damage disrupts cellular processes, impairs insulin function and contributes to complications like neuropathy, retinopathy and kidney disease.

Q: Why is reductive stress often overlooked in diabetes research?

A: Traditionally, scientists have focused on oxidative stress as the primary cause of cellular damage in diabetes. However, newer research proposes that reductive stress precedes oxidative stress and acts as the initial trigger. The difficulty in measuring reductive stress and its more subtle effects led to its underappreciation for decades, but advances in mitochondrial research have revived interest in its role.

Q: What strategies can help manage reductive stress in Type 2 diabetes?

A: Supporting healthy blood sugar regulation through good nutrition and regular movement is a practical starting point. Some researchers have also examined supplements such as coenzyme Q10 (CoQ10), alpha-lipoic acid (ALA), and methylene blue in connection with mitochondrial electron flow, though none has been established as a treatment for reductive stress.

Q: How do supplements like CoQ10 and alpha-lipoic acid help with reductive stress?

A: CoQ10 is involved in mitochondrial function by facilitating electron transfer in the ETC, which has been proposed to reduce the buildup of NADH. Alpha-lipoic acid (ALA) acts as an antioxidant and helps regenerate other protective molecules like glutathione. Whether either of these translates into meaningful changes in cellular redox balance or insulin sensitivity in people with diabetes has not been established, and neither is a substitute for medical care.

Most people think of tooth decay as a surface problem — something that starts on the outside of your tooth and works its way in. Brushing, flossing and regular dental visits target that outer layer, and they matter. But your teeth aren’t static objects. They’re living structures that constantly lose and regain minerals. That process depends on what’s happening inside your body, not just what you do at the bathroom sink.

One nutrient that rarely enters the conversation about dental health is vitamin K2. Unlike vitamin K1, which is abundant in leafy greens and primarily supports normal blood clotting, vitamin K2 is found mainly in fermented foods and certain animal products1 — foods that appear far less often in the typical American diet. That gap matters, because vitamin K2 plays a direct role in where calcium ends up inside your body — and whether it reaches your teeth at all.

Research links low vitamin K2 levels to measurable damage in the tissues that hold your teeth in place, and the relationship isn’t a simple on-or-off distinction. The findings suggest that as vitamin K2 status declines, the destruction becomes progressively worse. Those results raise an important question for anyone who wants to keep their natural teeth for life: Is your body getting what it needs to maintain them from the inside out?

Vitamin K2 Levels Fell as Gum Disease Became More Severe

A study published in Healthcare (Basel) investigated whether vitamin K2 blood levels were linked to periodontitis and whether those levels changed as the disease became more advanced.2 Periodontitis is the most advanced stage of gum disease. It develops when early gum inflammation progresses deeper below the gumline, destroying the bone and connective tissue that hold your teeth in place and eventually increasing the risk of loose teeth and tooth loss.

The researchers directly measured vitamin K2 levels in the blood of 100 generally healthy adults. Half had healthy gums, while the other half had diagnosed periodontitis. The goal was to determine whether vitamin K2 status reflected the severity, extent, and progression of the disease.

Because the study compared healthy individuals with patients at different stages of periodontal disease, it also allowed researchers to examine whether vitamin K2 declined steadily as the condition worsened instead of simply comparing healthy versus unhealthy mouths. That provides a clearer picture of how vitamin K2 relates to disease progression.

• The lowest vitamin K2 levels appeared in the people with the most advanced disease — The researchers found that average vitamin K2 blood levels measured 0.43 nmol/L in healthy adults but only 0.27 nmol/L in those with periodontitis. The difference remained statistically significant regardless of age or sex, showing that lower vitamin K2 was consistently associated with periodontal disease throughout the study population.

Even more striking, vitamin K2 levels dropped step by step as the disease became more severe. Average levels measured approximately 0.37 nmol/L in stage I disease, 0.27 nmol/L in stage II, 0.22 nmol/L in stage III and only 0.19 nmol/L in stage IV, the most advanced form. Instead of one sudden decline, vitamin K2 steadily decreased as destruction of the supporting tissues around the teeth increased.

The same pattern appeared when researchers examined how aggressively the disease progressed. Participants with the slowest progression (grade A) averaged 0.36 nmol/L, those with moderate progression (grade B) averaged 0.27 nmol/L and those with the fastest progression (grade C) averaged just 0.21 nmol/L.

• Lower vitamin K2 matched greater bleeding, deeper pockets and more bone destruction — The researchers compared vitamin K2 levels with individual signs of tissue damage. The strongest relationship appeared with bleeding during a dental examination. As vitamin K2 levels declined, bleeding on probing increased substantially, producing one of the strongest statistical associations in the study.

Lower vitamin K2 also corresponded with greater clinical attachment loss, meaning more of the tissues that anchor each tooth had been destroyed. Pocket depth increased as well. These pockets form when the gums pull away from the teeth, creating spaces where harmful bacteria collect and continue damaging the surrounding tissues. The lower the vitamin K2 level, the deeper these pockets became.

The researchers also found strong relationships between lower vitamin K2 and greater jawbone loss around the teeth. This finding matters because once the bone supporting a tooth disappears, that tooth becomes increasingly unstable. Together, bleeding, attachment loss, deep pockets and bone destruction all followed the same pattern as vitamin K2 declined.

• People with disease throughout the mouth had even lower vitamin K2 levels — The study also separated participants based on how much of their mouth was affected. Individuals whose disease involved less than 30% of the teeth had higher vitamin K2 levels than those whose disease had spread throughout much of the mouth. Patients with generalized periodontitis averaged about 0.26 nmol/L, compared with approximately 0.30 nmol/L in those whose disease remained localized.

That finding suggests vitamin K2 status was associated not only with how severe the disease became at individual teeth but also with how widely it spread across the mouth. In other words, lower vitamin K2 accompanied broader destruction of the tissues that support your teeth.

A practical challenge for you is simple: bleeding gums are easy to ignore because they rarely hurt. Yet this study showed that measurable tissue destruction and lower vitamin K2 frequently occur long before teeth become loose enough for people to seek treatment.

• Vitamin K2 supports several biological systems that protect the tissues around your teeth — The researchers discussed several reasons why vitamin K2 could influence periodontal health. One of its best-known jobs is activating proteins involved in building and maintaining healthy bone.

Vitamin K2 supports osteoblasts, the cells responsible for building new bone, while reducing the activity and formation of osteoclasts, the cells responsible for breaking bone down. This shifts the balance toward preserving the bone that anchors your teeth.

The paper also explains that vitamin K2 helps reduce production of RANKL, a signaling molecule that stimulates osteoclast formation. Fewer osteoclasts mean less bone breakdown. At the same time, vitamin K2 supports proteins involved in normal mineralization, allowing calcium to become incorporated into hard tissues instead of remaining in circulation.

For your mouth, that means vitamin K2 participates in maintaining the foundation beneath every tooth rather than affecting only the tooth itself. Healthy teeth require healthy supporting bone, and this study found lower vitamin K2 consistently accompanied greater loss of that foundation.

• The study identifies a strong association but stops short of proving cause and effect — One important strength of this research is that it directly measured vitamin K2 in blood samples instead of estimating intake from food questionnaires. The researchers also carefully excluded many factors that could distort the results, making the comparison between healthy participants and those with periodontitis more reliable.

At the same time, this was a case-control study, meaning it identified relationships rather than proving that low vitamin K2 directly caused periodontal disease. The researchers specifically state that additional clinical research is needed to determine whether improving vitamin K2 status alongside standard periodontal treatment improves long-term outcomes.

Even so, the findings establish an important message: vitamin K2 didn’t simply differ between healthy and unhealthy mouths. It closely tracked the severity, extent and progression of periodontal destruction across nearly every clinical measurement the researchers evaluated. Those findings show what happens when vitamin K2 levels are low. The next question is why — what exactly is vitamin K2 doing inside your teeth and the bone that supports them?

Vitamin K2 Helps Your Teeth Put Calcium to Work

An educational review from Rejuvenation Dentistry focuses on the practical side of this equation, specifically how vitamin K2 works alongside vitamin D3 and calcium to maintain strong enamel from the inside out.3 Getting enough calcium is only part of the equation.

Your body also needs nutrients that help direct calcium to the places where it belongs. Vitamin K2 plays a central role in that process by activating proteins responsible for incorporating calcium into mineralized tissues such as teeth and bones. If you focus only on calcium intake while overlooking vitamin K2, you miss an important part of the system that helps maintain healthy teeth throughout your life.

• Vitamin K2 activates the protein that locks calcium into your teeth — Vitamin K2 activates osteocalcin, a protein that binds calcium to hard tissues like enamel and bone. Without adequate vitamin K2, osteocalcin remains inactive and calcium circulates without being efficiently deposited where your teeth need it most.

Because enamel constantly loses small amounts of minerals to acids from bacteria and food, this activation step matters every day, not just during dental appointments.

• Vitamin D3 and vitamin K2 perform different jobs that complement each other — The review emphasizes that vitamin D3 and vitamin K2 work together instead of replacing one another. Vitamin D3 increases your body’s ability to absorb calcium from food, while vitamin K2 helps guide that absorbed calcium into the places where it belongs.

If you picture building a brick wall, vitamin D3 delivers the bricks to the jobsite while vitamin K2 is the mason who sets each one in place. Both steps matter. Without either one, the finished structure is weaker than it could be.

• Many people eat very little vitamin K2 without realizing it — Unlike vitamin K1, which is abundant in leafy green vegetables, vitamin K2 comes primarily from fermented foods and select animal foods. According to the review, that makes vitamin K2 deficiency more common than vitamin K1 deficiency in modern diets.

Healthy intestinal bacteria produce some vitamin K2. However, because food choices differ greatly from person to person, dietary intake remains an important contributor to overall vitamin K2 status.

• The review highlights whole-food sources before discussing supplements — Foods naturally rich in vitamin K2 include natto, certain fermented cheeses like Gouda, pastured egg yolks, grass fed meats like liver, and some other animal products. Vitamin K2 supplements also exist for individuals who struggle to obtain enough vitamin K2 through food alone.

Building your meals around nutrient-rich whole foods supplies vitamin K2 alongside protein, minerals, and many other compounds that support overall health. If you want stronger teeth over the long term, consistently eating foods that naturally contain vitamin K2 is a habit you build meal by meal instead of trying to correct years later.

How to Build Stronger Teeth from the Inside Out

Every day, your body is repairing the enamel on your teeth and maintaining the bone that keeps them firmly in place. Vitamin K2 is one of the nutrients involved in that process. If you focus only on cleaning your teeth without giving your body the nutrients it needs to maintain them, you’re overlooking an important part of lifelong oral health. Here are five practical steps to support your teeth from the inside out.

1. Eat more foods that naturally provide vitamin K2 — The richest dietary sources of vitamin K2 mentioned above have become much less common in modern diets, making low vitamin K2 intake surprisingly common. Instead of thinking about vitamin K2 as an occasional nutrient, make it part of your regular meal planning.

Adding one or two of these foods several times each week is a simple habit that supports healthy teeth, bones, and gums over the long term.

2. Fill dietary gaps with the right vitamin K2 supplement — If you rarely eat vitamin K2-rich foods, a high-quality supplement is a sensible option. Research suggests that for most adults, daily amounts between 90 and 180 micrograms (mcg) may provide nutritional support, while children up to age 10 generally require about 45 mcg daily and those between 10 and 18 years old about 90 mcg daily.

Some practitioners suggest taking vitamin K2 with your evening meal, especially if you already take vitamin D3, calcium, or magnesium, since this fits well with your body’s normal mineral metabolism.

Vitamin K2 supplements are available primarily as MK-4 and MK-7. MK-4 is the form naturally found in animal foods and remains in the bloodstream for a shorter time, while MK-7, the form abundant in natto, stays available much longer. Because people respond differently to each form, selecting the one that best matches your individual needs helps maintain consistent support for healthy calcium transport.

3. Treat vitamin D3 and vitamin K2 as partners — Vitamin D3 helps your body absorb calcium, but vitamin K2 helps direct that calcium into your teeth and bones instead of allowing it to accumulate in soft tissues. Taking one without enough of the other leaves your body with an incomplete system for handling calcium.

As a practical guideline, if your daily routine includes about 5,000 IU of vitamin D3, research suggests pairing it with approximately 180 micrograms of vitamin K2. Looking at these nutrients as a team instead of separate supplements helps your body put calcium where it benefits you most.

4. Pay attention to your gums before serious damage develops — Bleeding gums aren’t something to brush off. If your gums bleed when you brush or floss, appear swollen or have started pulling away from your teeth, view those changes as early warning signs. The study showed that lower vitamin K2 levels were associated with more extensive periodontal damage.

Addressing gum problems early gives you a much better opportunity to preserve the bone and connective tissue that keep your teeth stable.

5. Build one lasting habit instead of chasing quick fixes — You don’t need to overhaul your entire diet overnight. Pick one realistic goal this week, such as adding a pastured egg yolk to breakfast, choosing grass fed Gouda instead of processed cheese or including another vitamin K2-rich food in several meals. Once that habit feels effortless, add another. Small improvements repeated consistently almost always outperform dramatic changes that don’t last.

FAQs About Vitamin K and Tooth Decay

Q: How does vitamin K2 help protect my teeth?
A: Vitamin K2 activates proteins that help move calcium into your teeth and the bone that supports them. This helps maintain strong enamel and a healthy jawbone instead of leaving calcium circulating where it serves little benefit. Healthy teeth depend on this internal mineral balance just as much as they depend on daily brushing and flossing.

Q: What’s the connection between vitamin K2 and gum disease?
A: Researchers found that people with lower vitamin K2 blood levels had more severe periodontitis, including greater gum bleeding, deeper pockets around the teeth, increased attachment loss and more bone destruction. The study found a strong association between vitamin K2 status and the severity of periodontal disease, although it didn’t prove that low vitamin K2 directly caused the condition.

Q: Which foods provide the most vitamin K2?
A: The richest natural sources include natto, aged cheeses such as Gouda, pastured egg yolks and grass fed organ meats like liver. Because these foods aren’t common in many modern diets, some people consume much less vitamin K2 than they realize. If these foods are rarely part of your meals, a vitamin K2 supplement is another option.

Q: Why should vitamin D3 and vitamin K2 be taken together?
A: Vitamin D3 increases the amount of calcium your body absorbs, while vitamin K2 helps direct that calcium into your teeth and bones. Taking vitamin D3 without enough vitamin K2 leaves your body with more calcium to manage but fewer tools to help place it where it belongs. Balancing these nutrients supports healthy calcium metabolism.

Q: What are the first signs that my gums need attention?
A: Bleeding when you brush or floss, swollen or tender gums, receding gums and persistent bad breath are all warning signs that deserve attention. Gum disease often progresses quietly before pain develops, so recognizing these early changes and supporting your oral health through proper nutrition and daily dental care gives you a better chance of protecting your natural teeth for the long term.

Neurodegenerative diseases (NDs) are disorders characterized by the progressive loss of structure or function of neurons, leading to their eventual death. This decline disrupts essential brain functions, resulting in symptoms that significantly impair daily living and overall quality of life.

Common neurodegenerative diseases include Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS).1 Individuals affected by these conditions often experience memory loss, impaired movement, and difficulties with speech and coordination. As the diseases advance, patients may face severe cognitive and physical challenges, necessitating extensive care and support.

Neurodegenerative diseases now affect millions worldwide, with Alzheimer’s alone responsible for approximately 60% to 70% of dementia cases.2 On the other hand, the prevalence of Parkinson’s disease is expected to double by 2040, underscoring a growing public health concern.3 Additionally, ALS affects about 2 per 100,000 people in Europe and the U.S., with no known cure currently available.4

Risk Factors Associated with Neurodegenerative Diseases

Understanding the underlying causes of NDs is complex, as they often involve a combination of factors. For example, genetic mutations can predispose individuals to conditions like Alzheimer’s and Parkinson’s. According to a review published in the NPJ Parkinson’s Disease journal, genetic factors are linked to 56% to 79% of the risk for developing Alzheimer’s disease.5

• Environmental toxins — Exposure to heavy metals and pesticides, may contribute to neuronal damage. According to the aforementioned study:

“Several studies have suggested that lead (Pb), arsenic (As), and methyl mercury (MeHg) are also neurotoxins and can disrupt brain function, cause cognitive dysfunction, and increase the risk of AD and PD by disrupting mRNA splicing, the ubiquitin-proteasome system, the electron transport chain, and oxidative stress.”6

• Lifestyle factors — Poor diet, lack of exercise and chronic stress exacerbate NDs by affecting overall brain health and function. The progression from these underlying causes to full-blown NDs involves a cascade of biological events. Neurons, the brain’s communication cells, begin to lose their structure and function due to factors like oxidative stress and inflammation.

This deterioration disrupts the brain’s ability to process information, leading to symptoms such as memory loss and impaired motor skills. Over time, the cumulative effect of these disruptions results in the characteristic decline associated with NDs.

• Diagnosing NDs can be challenging — Often, symptoms overlap with other conditions, making it difficult to pinpoint the exact disease. For instance, memory loss could be attributed to normal aging, stress, or other medical issues, leading to potential misdiagnosis. Additionally, the lack of definitive biomarkers for many NDs means that diagnosis often relies on clinical assessments and patient history, which can be subjective and vary between practitioners.

• Limitations in diagnostic tools complicate the process — Imaging techniques like MRI and CT scans show brain changes, but these are not always specific to NDs. Blood tests and genetic screenings may offer clues but are not conclusive.

As a result, patients may undergo a lengthy diagnostic journey, experiencing uncertainty and anxiety while seeking answers. This underscores the need for more precise and reliable diagnostic methods to improve early detection and treatment outcomes.

Beyond the immediate symptoms, neurodegenerative diseases lead to profound emotional and financial burden for patients and their families. The progressive nature of these disorders often results in loss of independence, increased healthcare costs and emotional stress. Addressing these multifaceted challenges is crucial in improving patient outcomes and enhancing the quality of life for those affected.

What Research Shows About Probiotics and Alzheimer’s Disease

A 2023 study published in the journal Nutrients7 investigated the impact of probiotics on individuals diagnosed with Alzheimer’s disease. The research, conducted by Taiwanese researchers, aimed to determine whether different doses of a multi-strain probiotic supplement could influence neurotrophic, inflammatory and oxidative-stress markers, and cognitive function, in patients with Alzheimer’s disease.

• Investigating the effects of probiotics — The study involved 40 adults diagnosed with Alzheimer’s disease, 32 of whom completed the 12-week trial. In this double-blind, active-controlled design, participants were randomized to a lower-dose or a higher-dose multi-strain probiotic supplement — there was no placebo group.

Both groups took a probiotic capsule containing Bifidobacterium longum BLI-02, B. breve Bv-889, B. animalis lactis CP-9, B. bifidum VDD088, and Lactobacillus plantarum PL-02, differing only in dose. The goal was to assess changes in brain-derived neurotrophic factor (BDNF), inflammatory and oxidative-stress markers, and cognitive function as a result of the higher-dose probiotic intervention.

• What the study found on cognitive function — Cognitive test scores (MMSE, ADAS-Cog, ADL, and CDR) did not differ significantly between the higher-dose and lower-dose groups after 12 weeks. Researchers noted a nonsignificant trend toward less cognitive deterioration in the higher-dose group, though this did not reach statistical significance.*

• Inflammation and antioxidant markers — The higher-dose group showed a 36% increase in brain-derived neurotrophic factor (BDNF), a reduction in the inflammatory marker IL-1β, and an increase in the antioxidant enzyme superoxide dismutase (SOD), compared to the lower-dose group.* “Considering these findings, specific probiotics demonstrate robust and effective antioxidant capabilities,” the study authors reported.8

Probiotics Reduce Inflammation and Oxidative Stress

The mechanism behind these improvements is believed to involve the gut-brain axis, a communication network between the gastrointestinal tract and the brain.

• Probiotics balance your gut health — Probiotics help maintain a healthy balance of gut microbiota, which in turn may influence brain function. By promoting a diverse and balanced microbiome, probiotics may help reduce systemic inflammation and oxidative stress, both of which are implicated in the progression of Alzheimer’s disease. For more information on how gut health affects your mental health, read “Gut Health’s Impact on Mental Well-Being.”

• Benefits of SCFAs — Short-chain fatty acids (SCFAs) are metabolites produced by beneficial bacteria in the gut. SCFAs have been shown to support brain health by providing energy to neurons and reducing inflammation. The increased abundance of Lactobacillus species in the probiotic group likely contributed to higher SCFA levels, fostering an environment conducive to cognitive stability and improvement.

• Benefits are observed in a short amount of time — While this trial’s cognitive measures did not reach statistical significance over 12 weeks, the BDNF, inflammation and oxidative-stress changes emerged in that same short window — suggesting some biological effects of probiotic supplementation may appear relatively quickly, even though longer or larger trials are needed to determine whether measurable cognitive benefits follow.*

Comparing the higher- and lower-dose groups, the higher dose was associated with measurable improvements in BDNF, inflammatory and oxidative-stress markers, while cognitive test scores were similar between groups. This suggests probiotic dose may influence some physiological markers of brain health, though further research is needed to determine whether this translates into measurable cognitive benefit.

Probiotics’ Mechanisms of Action Against Neurodegenerative Disorders

Biologically, the action of probiotics involves several interconnected pathways. By restoring a healthy balance of gut bacteria, probiotics may help reduce the production of harmful substances like lipopolysaccharides (LPS) that trigger inflammation in the brain.9

• Enhancing the integrity of the gut barrier — They may help prevent the leakage of proinflammatory agents into the bloodstream, which could otherwise reach the brain and exacerbate neuroinflammation.10

• Affecting neurotransmitter production — Probiotics may influence the production of neurotransmitters such as dopamine and gamma-aminobutyric acid (GABA).11 These chemicals are crucial for mood regulation and cognitive function. By increasing the levels of these neurotransmitters, probiotics may contribute to improved mental health and greater cognitive resilience against the degenerative processes of Alzheimer’s disease.

Four Ways to Support Your Brain Through Gut Health

Your gut microbiome is closely connected to brain function, and emerging research suggests it may influence cognitive health and play a role in the risk of neurodegenerative conditions. For example, a study published in Scientific Reports showed that certain bacterial strains in the gut, such as Collinsella, Lachnospira, and Veillonella, increased the risk of Alzheimer’s disease.12

However, they also identified strains that provide protective benefits against Alzheimer’s disease, such as Eubacterium nodatum and Eisenbergiella. These produce short-chain fatty acids (SCFAs), particularly butyrate, from dietary carbohydrates.

Butyrate nourishes your colonic epithelial cells, reinforcing the intestinal barrier. SCFAs also stimulate mucin production, creating a protective shield against harmful bacteria. Akkermansia muciniphila also produces SCFAs, and research has shown that Alzheimer’s patients tend to have very low levels of this important keystone species.13 Here are four strategies that may help support the Akkermansia in your gut to enhance your brain health:

1. Increase Akkermansia through targeted diet and supplementation — Prioritize foods and supplements that promote the growth of Akkermansia. Include well-cooked, prebiotic-rich vegetables and fiber sources that nourish this crucial bacterium.

Look for well-researched Akkermansia-supporting probiotic or postbiotic formulas, which may help support gut barrier integrity and, in turn, healthy inflammation levels. Avoid processed foods and high-fat diets that can hinder Akkermansia growth.

2. Enhance beneficial short-chain fatty acids — Focus on increasing butyrate-producing bacteria alongside Akkermansia which researchers believe may help support healthy amyloid clearance processes in the brain. Incorporate fermented foods and resistant starches that feed these beneficial microbes.

Tailor your carbohydrate intake to support your unique microbiome, aiming for at least 250 grams of targeted carbs daily, and adjust based on your activity level to optimize Akkermansia and short-chain fatty acid production.

3. Support your gut-brain connection — Optimize your gut barrier integrity to prevent inflammatory compounds from reaching your brain. This includes removing inflammatory processed foods and supporting the growth of protective bacteria like Akkermansia, which strengthens your intestinal lining.

Maintain a balanced diet with sufficient carbohydrates tailored to your microbiome, and consider a well-researched Akkermansia-supporting supplement, taken as advised by your healthcare provider, to help sustain your levels.

4. Address systemic inflammation by promoting Akkermansia diversity — Lower inflammation throughout your body by enhancing microbiome diversity, with a specific emphasis on increasing Akkermansia.

Eliminate vegetable oils and other proinflammatory fats that damage gut bacteria, and incorporate foods that reduce inflammatory markers while supporting Akkermansia growth. Regularly monitor biomarkers such as C-reactive protein levels to track your progress in reducing systemic inflammation and maintaining a healthy gut microbiome.

Additional Strategies That May Support Alzheimer’s Risk Reduction

Aside from optimizing your gut health and Akkermansia levels, there’s a plethora of helpful Alzheimer’s prevention strategies, several of which are outlined below:

• Avoid gluten and casein (primarily wheat and pasteurized dairy, but not dairy fat, such as butter) — As noted in a 2022 study,14 your blood-brain barrier is negatively affected by gluten. When bacteria enter your bloodstream, the risk of Alzheimer’s disease increases. Other cognitive disorders are linked to a weakened blood-brain barrier as well, such as Parkinson’s disease, anxiety and depression.

• Make sure you’re getting enough animal-based omega-3 fats — Omega-3 fats, namely EPA and DHA, have been studied for a possible role in protecting brain cells and supporting healthy cognitive aging. That said, omega-3s are PUFAs, so don’t overdo it.

• Optimize your vitamin D level with safe sun exposure — Strong links between low levels of vitamin D in Alzheimer’s patients and poor outcomes on cognitive tests have been revealed. In a 2023 observational study,15 vitamin D supplementation was associated with a 40% lower rate of incident dementia.

The best way to get vitamin D is through sensible sun exposure, aiming for a blood level between 60 and 80 ng/mL. However, you need to purge vegetable oils from your body before going into the sun at solar noon. The LA in your skin oxidizes when exposed to sunlight, causing inflammation and skin damage.

To protect your skin, avoid sun exposure during solar noon for four to six months as you work on removing LA from your body. Stick to sunlight during early morning and late afternoon in the meantime. For additional skin defense, you can take astaxanthin, a low-dose aspirin or molecular hydrogen. Niacinamide cream will also lower your risk of skin damage.

• Keep your fasting insulin levels below 3 — Insulin resistance is linked to accelerated brain aging, as well as neurodegeneration.16

• Eat a nutritious diet, rich in folate — Vegetables, without question, are your best form of folate. Avoid supplements like folic acid, which is the inferior synthetic version of folate. Research shows that folate is a protective factor against Alzheimer’s disease.17

• Avoid and eliminate mercury and aluminum from your body — Dental amalgam fillings, which are 50% mercury by weight, are one of the major sources of heavy metal toxicity. Make sure you use a biological dentist to have your amalgams removed. Sources of aluminum include antiperspirants, nonstick cookware and vaccine adjuvants.

• Make sure your iron isn’t elevated and donate blood if it is — A study18 published in Aging Medicine shows that excess iron increases your risk of Alzheimer’s disease by initiating the Fenton reaction, leading to increased oxidative stress.

• Exercise regularly — Exercise triggers beneficial changes that support cognitive function. Particularly, it’s been shown to improve blood flow to the brain, leading to an increase in biomarkers related to improved neuronal plasticity and better cell survival.19

• Eat blueberries and other antioxidant-rich foods — Wild blueberries, which have high anthocyanin and antioxidant content, are known to guard against neurological diseases.

• Challenge your mind daily — Mental stimulation, such as learning to play a musical instrument, is associated with a decreased risk of Alzheimer’s.20

• Avoid anticholinergics and statin drugs — Drugs that block acetylcholine, a nervous system neurotransmitter, have been shown to increase your risk of dementia. These drugs include certain nighttime pain relievers, antihistamines, sleep aids, certain antidepressants, medications to control incontinence, and certain narcotic pain relievers.

Statin drugs are particularly problematic because they suppress the synthesis of cholesterol, deplete your brain of CoQ10 and neurotransmitter precursors, and prevent adequate delivery of essential fatty acids and fat-soluble antioxidants to your brain by inhibiting the production of the indispensable carrier biomolecule known as low-density lipoprotein.

Early research is exploring whether beneficial bacteria could help support cognitive health in conditions like Alzheimer’s and Parkinson’s, though more research is needed to confirm effects on cognitive decline.

Q: What research supports the benefits of probiotics for Alzheimer’s patients?

A: A 12-week clinical trial published in Nutrients compared higher- and lower-dose multi-strain probiotic supplementation in patients with Alzheimer’s disease (there was no placebo group). The higher dose was associated with increased BDNF and antioxidant activity and reduced inflammatory markers, though cognitive test scores did not differ significantly between groups.

Q: What mechanisms make probiotics beneficial for brain health?

A: Probiotics help may help reduce inflammation by lowering harmful substances like lipopolysaccharides (LPS), enhancing gut barrier integrity, and influencing neurotransmitter production (e.g., dopamine and GABA). They also promote the production of short-chain fatty acids (SCFAs), which support brain health.

Q: Can improving gut health help prevent neurodegenerative diseases?

A: Possibly. A diverse gut microbiome, particularly the presence of beneficial bacteria like Akkermansia muciniphila, may play a role in supporting healthy inflammation levels and could contribute to long-term brain health, though more research is needed to confirm a protective effect against neurodegeneration. Consuming prebiotic-rich foods, fermented foods, and maintaining a fiber-rich diet can support gut health.

Q: What other lifestyle changes can support brain health and reduce Alzheimer’s risk?

A: In addition to probiotics, strategies like avoiding processed foods, eliminating heavy metal exposure (e.g., mercury and aluminum), maintaining optimal vitamin D and omega-3 levels, exercising regularly, and engaging in mental stimulation activities can help prevent cognitive decline and support brain health.

Chronic inflammation and cancer are health challenges that affect millions of individuals worldwide. Inflammation is your body’s natural response to injury or infection, characterized by redness, swelling and pain. However, when inflammation becomes persistent, it is associated with tissue damage and with the development of various diseases, including cancer.

Cancer itself is marked by the uncontrolled growth and spread of abnormal cells, which invade surrounding tissues and form harmful tumors. If left untreated, these conditions significantly impair quality of life and increase mortality rates. Mitochondria, often referred to as the powerhouses of the cell, play a key role in producing adenosine triphosphate (ATP), the energy currency essential for numerous cellular functions.

When mitochondrial function is compromised, ATP production decreases, leading to cellular energy deficits. This reduction in energy impairs the cell’s ability to regulate normal processes, which researchers have linked to conditions that favor chronic inflammation.

According to research published in Immunity,1 impaired mitochondrial function activates the NOD-like receptor protein 3 (NLRP3) inflammasome, a key component in the inflammatory response. The researchers propose that this activation sustains inflammation and may create conditions that favor cancer development by allowing damaged cells to survive.

An important note: This work was carried out in cultured cells and in frog tadpoles, so its findings describe a mechanism, not a demonstrated effect in people.

Mitochondrial Function Is Intricately Involved in Inflammation and Cancer

The impact of mitochondrial dysfunction on inflammation and cancer is significant. Studies show that approximately 20% of all cancers are linked to chronic inflammation, highlighting the strong connection between these conditions.2 Additionally, individuals with mitochondrial disorders are at a higher risk of developing inflammatory diseases compared to the general population.3

• Millions of Americans are affected by mitochondrial dysfunction — In the U.S. alone, chronic inflammatory conditions affect close to 125 million adults,4 while cancer remains the second leading cause of death, accounting for more than 613,000 fatalities each year.5 Moreover, research indicates that mitochondrial dysfunction contributes to the resistance of cancer cells to conventional therapies, making treatment more challenging.6

• Why mitochondrial health is drawing research attention — These figures help explain why mitochondrial function has become an active area of investigation in inflammation and cancer research.

Beyond their direct effects, chronic inflammation and cancer are associated with a cascade of additional health problems. Persistent inflammation is associated with cardiovascular diseases, diabetes and neurodegenerative disorders, further compounding the burden on affected individuals.

• Mitochondrial dysfunction is under investigation as a factor in cancer — Cancer progression often results in debilitating symptoms such as pain, fatigue and loss of organ function, which drastically reduces life expectancy and quality of life.
Understanding the role of mitochondrial dysfunction in inflammation and cancer not only illuminates possible therapeutic targets but also underscores why researchers are examining mitochondrial health across a wide range of conditions.

• Mitochondrial dysfunction is a key player in the development of NLRP3-related conditions — When mitochondria fail to produce adequate ATP, it sets off a cascade of cellular stress signals.

These signals activate the NLRP3 inflammasome, a protein complex that plays a significant role in the body’s inflammatory response.7 The activation of this inflammasome is linked to various diseases, including chronic inflammation and cancer, as it is associated with uncontrolled cell death and tissue damage.

What the Study Found About Mitochondrial Function and Inflammation

A 2025 study investigated the intricate relationship between mitochondrial function and the activation of the NLRP3 inflammasome. The research focused on understanding how the inhibition of oxidative phosphorylation (OXPHOS), the process by which mitochondria produce ATP, affects cell death and inflammation.

The study employed various cell types, including myeloid cells, primary murine microglia, human monocyte-derived macrophages, HCT116 and HeLa cells, as well as conducted in vivo experiments using Xenopus laevis tadpoles.8 Note: This is laboratory and animal research that identifies a mechanism in cultured cells and amphibians; it does not measure outcomes in people, and the findings below should be read on those terms.

• The NLRP3 inflammasome negatively impacts mitochondrial health — The population studied encompassed a diverse range of cells to mimic different physiological conditions. The findings revealed that activators of NLRP3 significantly hinder mitochondrial ATP production, which in turn suppresses apoptosis, the process of programmed cell death.

This suppression allows damaged cells to survive longer than they should, which the authors describe as a plausible contributor to inflammation and, over time, to cancer development. The study demonstrated that when OXPHOS is inhibited, mitochondrial cristae — the inner folds of mitochondria — undergo structural changes that trap cytochrome c, a molecule essential for apoptosis.9

• Other factors that diminish apoptosis — The research also showed that various NLRP3 activators, such as nigericin, imiquimod and extracellular ATP, inhibit apoptosis not by activating the inflammasome directly, but through their disruptive effects on mitochondrial function. These compounds cause the closure of crista junctions, preventing cytochrome c from being released into the cytoplasm, which is a necessary step for apoptosis to proceed.

• The impact of viral infections on mitochondrial function and apoptosis — It was observed that infections like SARS-CoV-2 could strongly suppress apoptosis by inhibiting the cleavage of caspase-3, an enzyme involved in the execution of apoptosis. This suppression not only hinders the removal of infected cells but also facilitates the activation of the NLRP3 inflammasome, thereby promoting an inflammatory response.10

Why Mitochondrial Function Matters Across Chronic Disease

Biologically, the mechanism at play involves the inhibition of mitochondrial ATP production by NLRP3 activators. When OXPHOS is blocked, mitochondria cannot produce sufficient ATP, leading to the rearrangement of cristae and retention of cytochrome c within the mitochondria. This retention prevents apoptosis, allowing damaged cells to survive and multiply unchecked.

• The process of NLRP3 signaling and activation — The suppression of ATP production provides a necessary signal for the activation of NLRP3. However, full activation of NLRP3 requires a second signal, highlighting the complexity of the inflammasome’s regulation.11

The study also compared the effects of different NLRP3 activators and OXPHOS inhibitors, revealing that while all these agents suppress apoptosis, only certain ones could activate NLRP3 without an additional signal.

• What this may mean for future research — This comparison highlights the intricate relationship between mitochondrial function and inflammasome activation, suggesting that modulating mitochondrial processes may warrant further study as an approach to influencing inflammation.12

The research provides mechanistic evidence that mitochondrial dysfunction, specifically through the inhibition of OXPHOS, plays a pivotal role in suppressing apoptosis and activating the NLRP3 inflammasome.

This dual action not only fosters a proinflammatory environment but also allows for the survival of malignant cells, thereby linking reduced mitochondrial function to the progression of inflammation and cancer.13 As noted on Georgi Dinkov’s blog, the study demonstrates that mitochondrial dysfunction is a key player in both cancer and inflammation:14

“Yet another study, which demonstrates the inseparable link between metabolism and ‘structural’ problems such as cellular integrity and lifecycle (e.g. apoptosis), as well as mysterious processes of systemic inflammation, often occurring without any cause that medicine can identify.

Both of these processes are highly visible in cancer — i.e., lack of apoptosis in ‘cancer’ cells despite their wrecked genome and metabolic dysfunction, as well as their highly inflamed nature that ‘recruits’ nearby cells to the ‘cancer’ process through the cytokines the ‘cancer’ cells produce and releases in the blood.

In other words, all that takes for systemic inflammation and even cancer (i.e., lack of apoptosis in damaged cells) to form is reduced mitochondrial function, resulting in a prolonged drop of ATP levels.

Thus, chronic stress, inflammatory diet (PUFA anyone?), endocrine disruptors, and the ‘modern’ life characterized by never-ending soul-crushing routines are all direct causes of all our ailments as the one thing all those pathological processes have in common is their profoundly suppressive effects on mitochondria/OXPHOS.”

How to Address Mitochondrial Dysfunction and Reduce Inflammation

Your mitochondria power every cell in your body. When they don’t work properly, inflammation rises and damaged cells multiply instead of dying off naturally. The following are general dietary and lifestyle measures associated with mitochondrial and metabolic health. They are not a treatment for any disease, and they are not a substitute for care from your healthcare provider:

1. Eliminate processed foods and vegetable oils — The modern diet is rife with processed foods and vegetable oils rich in linoleic acid (LA) that damage your gut microbiome and promote harmful bacteria.

Though LA is an essential fatty acid required for normal mitochondrial function, when consumed in excess, it can compromise cellular energy production, so the goal is to bring intake back to historical levels, not to remove it entirely. Aim to keep your LA intake within 2 to 5 grams per day from all sources To help track your LA intake, enter your daily meals into the Food Buddy feature in the Pax health platform, and use its Seed-Oil Sleuth feature to check the LA content of individual foods.
In addition to processed foods, avoid nuts and seeds as well to reduce LA intake. It’s also advisable to avoid dining out, since most restaurants use vegetable oils in their cooking, sauces and dressings.
Additionally, limit your consumption of chicken and pork, which are typically high in LA. Replace processed foods with whole, unprocessed foods and healthy fats such as grass fed butter, tallow, and ghee.
2. Optimize carbohydrate intake — Carbohydrates play an important role in supporting mitochondrial function since glucose is the preferred fuel for energy production at the cellular level. Tailor your carbohydrate consumption to support cellular energy by aiming for at least 250 grams of targeted carbohydrates daily for most adults. Individuals with higher activity levels typically require more.

Introduce carbohydrates gradually to allow your gut to adapt, thereby minimizing digestive issues and endotoxin levels. Begin with white rice and whole fruits to nourish beneficial bacteria before considering vegetables, whole grains and starches. Avoiding high-fiber diets initially is important if your gut microbiome is compromised, as excessive fiber will increase endotoxin levels.

If your gut health is severely compromised, focus on easily digestible carbohydrates like dextrose water for the first week or two. Sip it slowly throughout the day to support gradual gut healing.

3. Reduce exposure to environmental toxins — Exposure to synthetic endocrine-disrupting chemicals (EDCs), estrogen and pervasive electromagnetic fields (EMFs) further impairs your cells’ ability to generate energy efficiently. Energy deficit makes it challenging to sustain the oxygen-free gut environment necessary for beneficial bacteria like Akkermansia to flourish.

Further, a lack of cellular energy creates an environment in your gut that favors endotoxin-producing bacteria, damaging mitochondria and creating a vicious cycle of worsening health. By tackling excess LA, estrogens (xenoestrogens found in everyday items like plastic), EDCs and EMFs, you help restore your cellular energy.

4. Support NAD+ levels — Niacinamide is a precursor to NAD+, which supports mitochondrial energy production. NAD+ also enables proper cell death signaling and supports your immune system’s ability to identify and remove damaged cells.

5. Get safe sun exposure — Daily sun exposure is also important, for two reasons: its near-infrared wavelengths are absorbed by mitochondria to support cellular energy production15,16 and they also stimulate mitochondrial melatonin — a potent antioxidant that neutralizes reactive oxygen species right where they’re generated.17,18

One caveat: It’s important to avoid direct sunlight during peak hours (from 10 a.m. to 4 p.m. in most U.S. regions) until you’ve eliminated vegetable oils from your diet for at least four to six months to reduce sunburn risk associated with stored linoleic acid.

Frequently Asked Questions About Mitochondrial Dysfunction and Inflammation

Q: What is the connection between mitochondrial dysfunction and chronic inflammation?

A: When mitochondria underproduce ATP, the body perceives this energy deficit as cellular stress. This stress triggers the NLRP3 inflammasome, a protein complex that amplifies inflammation. Over time, chronic inflammation damages tissues and has been associated with serious conditions including cancer.

Q: How does mitochondrial dysfunction contribute to cancer development?

A: Damaged mitochondria hinder the cell’s ability to undergo apoptosis (programmed cell death). When apoptosis is suppressed, abnormal cells survive longer than they should, which in laboratory models allows mutations to accumulate. Researchers are investigating whether chronic inflammation associated with impaired mitochondrial function contributes to cancer progression.

Q: Why is linoleic acid problematic for mitochondrial health?

A: LA, found in most vegetable oils and many processed foods, is essential in small amounts but problematic in excess. Consuming high amounts has been associated with gut dysbiosis (an imbalance of gut bacteria) and increased inflammation. The recommended range is 2 to 5 grams per day — enough to meet the body’s requirement, without the excess typical of a modern diet.

Q: Can improving carbohydrate intake help restore mitochondrial function?

A: Glucose is a key fuel for energy production (via oxidative phosphorylation) in the mitochondria. By incorporating adequate, easily digestible carbohydrates — such as white rice or whole fruits — you’ll be able to support cellular energy and encourage healthier gut bacteria. This approach is especially important if your gut microbiome is already compromised.

Q: What lifestyle strategies can support better mitochondrial function?

A: Key strategies include eliminating processed foods (especially those high in vegetable oils), optimizing carbohydrate intake, reducing exposure to toxins like endocrine disruptors and heavy electromagnetic fields, getting regular sun exposure, and supporting NAD+ levels. These measures are associated with lower inflammation and improved mitochondrial function markers. They are general wellness measures, not a treatment or preventive for any disease.

Every once in a while, someone looks at an industry that has become too complicated and decides it doesn’t have to be that way. Nest did it with the thermostat, turning a fussy household control panel into something people could understand at a glance.

The invention of GPS-enabled digital mapping revolutionized navigation. If you’re old enough, you’ll remember the multi-step procedure we had to go through: planning routes the night before, printing the turn-by-turn sheet, unfolding a map at a red light, or pulling over to ask a stranger for directions. Now you just enter a destination, and a voice guides you the whole way, rerouting on its own when you miss a turn. Now, anyone with a smartphone can drive to unfamiliar destinations without the hassle of getting lost.

Supplements have been waiting their turn. For as long as most of us can remember, they’ve involved remembering to take fistfuls of pills and capsules, turning into a clinical chore performed out of a sense of obligation to one’s health — and abandoned due to the complexity of the schedules and the busyness of modern life.

A supplement routine that only works when days are relaxed and organized usually ends in feelings of personal failure. But the failure was in the design, not you. And a design problem is something that can be fixed, which is precisely what we’re doing.

One Idea, Told Ten Ways

Everything in this article series has been a single idea told from several angles: by redesigning supplements to fit modern lifestyles, we can help people improve their nutrition and hence their health — as opposed to insisting that people just work on their willpower.

The hidden burden that makes so many people quit a supplement routine is removed, by design, because the research shows that complicated regimens and plain forgetfulness are among the biggest reasons people stop a daily routine, while a simplified one is among the strongest factors that keep them going.1

The fistful of pills oftentimes doesn’t fit the way people live, simply because they forget to take them when busy, and most days are that way. For many, a simpler food-centered model, where nutritional powder is added to food you’re eating anyway, is the answer to that dilemma.

The mega-dose game is also up for revision, as how much of a nutrient actually reaches you depends heavily on its form and delivery method, not the total dose.2 The psychology of why we quit is also being addressed by coming up with a routine so simple it can survive your worst days, anchored to something you already do, because a behavior repeated in a stable, everyday context is the kind that becomes automatic and lasts.3

Food-centered supplementation even tackles the self-blame that comes from backsliding. When you view a nutritional supplement as part of your diet, you’re less likely to view a missed dose as a personal failure. And without the self-shaming, you’re more likely to just pick up where you left off. As research has shown, treating yourself kindly after a slip is linked to better follow-through.4

The test every decision in this approach must pass is “does this fit the life of a busy, imperfect person?” When the answer is yes, the engineering has done its job — by disappearing into a routine so natural you barely think of it as a routine at all.

The Bottom Line

The whole article series comes down to this: a supplement only helps if you take it, you’ll only keep taking it if it fits your real life, and fitting your life is a design choice the industry has spent decades ignoring. We’re choosing to make it a central point instead. We want to make supplements you’ll use long enough for them to make a difference. We’ve been working toward this for a long time, and we’re glad you’re here for it.

Frequently Asked Questions

Q: Why do so many supplement routines fail?
A: Most fail because they ask too much of you. A complicated routine depends on a calm, organized day, and real life rarely works that way. When you have to remember multiple bottles, doses, and timing rules, the routine becomes easy to skip. A better model removes as much friction as possible so consistency feels less like a daily test.

Q: Why does a food-first supplement format make sense?
A: A food-first format connects supplements to the way you already nourish yourself. Instead of treating supplements like a separate clinical task, you add nutrition to a meal you already planned to eat. That makes the routine feel more natural and much easier to repeat.

Q: Are fewer pills really better?
A: Fewer pills can make a routine easier to keep. The point is not to remove useful nutrients. The point is to stop turning supplementation into a pile of capsules that feels like a clinical chore. A simpler format with fewer pills can help you stay consistent without relying so heavily on willpower.

Q: Why is the “mega-dose” approach being reconsidered?
A: More is not always better. The amount listed on a label does not tell you how much your body can absorb or use. Nutrient form, delivery method, and dose all matter. A sensible supplement focuses on what reaches you in a useful form, not just what looks impressive on the bottle.

Q: What’s the main takeaway from this article series?
A: A supplement only helps if you actually take it, and you’ll only keep taking it if the routine fits the life you live. Make it simple, food-first, and staying consistent stops being such a battle.

Omega-3 fats are essential for life itself, powering everything from the way your heart pumps to how your brain processes information. Your body can’t produce these fats on its own, which is why you need to obtain them from outside sources. Fatty fish like wild-caught salmon, sardines, and mackerel are traditional foods rich in omega-3s, while supplements such as fish oil and krill oil have become popular for those who want a concentrated dose.

The problem isn’t just getting omega-3s into your system — it’s whether your body absorbs and uses them effectively. Krill oil has gained attention because it delivers omega-3s in a phospholipid form, which slips into your cell membranes more easily. Fish oil, on the other hand, usually comes in triglyceride or ethyl ester forms, requiring more processing before your body can use it.

This structural difference changes how well you absorb fatty acids and how much benefit you actually receive. A study published in Food Chemistry: X showed clear differences in absorption depending on both the omega-3 source and formulation.1 Understanding these differences directly affects the benefits you feel in your heart, brain, joints, and beyond.

Krill Oil Shows a Clear Edge Over Fish Oil in Absorption

For the Food Chemistry: X study, researchers analyzed 26 high-quality randomized controlled trials with data collected between 2003 and 2023.2 The goal was to compare how well your body absorbs omega-3 fats from different sources — fish oil and krill oil.

Researchers focused on key markers in the blood, such as the omega-3 index, maximum blood concentration, time to reach peak levels, and the total exposure over time. These are standard ways scientists measure how efficiently nutrients get into your system and how long they stay there.

• Krill oil raised omega-3s more at lower doses — The findings showed that krill oil was more effective than fish oil at raising blood omega-3 levels when given at lower doses, while fish oil needed higher amounts to achieve a similar effect. When dosages were under 2,000 milligrams (mg), krill oil consistently outperformed fish oil.

This means if you take krill oil, you could use a smaller dose and still improve your omega-3 status. Fish oil required higher intakes — sometimes above 3,000 mg — to move the omega-3 index upward in a meaningful way. The omega-3 index is the percentage of EPA and DHA in your red blood cell membranes, and higher scores are strongly linked to better heart and brain outcomes.

• Fish oil emulsions delivered strong short-term results but come with a downside — While standard fish oil capsules lagged behind krill oil, emulsified forms of fish oil were an exception. Emulsions are blends where the oil is broken into tiny droplets, making it easier for your digestive system to process. These emulsions increased peak blood concentrations of omega-3s more than either regular fish oil or krill oil, meaning your body gets a faster boost.

Fish oil emulsions do carry some downsides, however, and rancidity is one of the main concerns. Because emulsions mix oil with water to improve absorption, they have a much larger surface area exposed to oxygen compared to standard capsules. That makes them more vulnerable to oxidation, the chemical reaction that turns fats rancid.
When fish oil oxidizes, it produces harmful byproducts that increase inflammation instead of reducing it — the exact opposite of what you want from omega-3s.

• High-dose fish oil improved long-term levels but with serious trade-offs — Fish oil above 3,000 mg per day raised the omega-3 index more strongly than lower doses. However, the researchers cautioned that higher intakes also raised the risk of unpleasant side effects, including digestive upset and excessive blood thinning.

High doses of omega-3s, especially from supplements, have also been linked to an increased risk of atrial fibrillation, a serious heart rhythm problem.3 This means that while high-dose fish oil works, it comes with a price. Krill oil at lower doses delivered a safer path to similar benefits without forcing your body to handle such a heavy load.

• Krill oil phospholipids gave it a unique advantage — The key reason krill oil worked better at lower doses was its structure. In krill oil, omega-3s are attached to phospholipids, a type of fat that naturally makes up your cell membranes. Because your cells are already built from phospholipids, this form of omega-3 slips in more easily.

The researchers explained that phospholipids in krill oil have amphiphilic properties, meaning they dissolve well in both water and fat. This makes them more compatible with your digestive system and easier to transport into your bloodstream. Fish oil, by contrast, usually contains triglycerides or ethyl esters, which are less efficient because they require pancreatic enzymes and bile acids to be broken apart before absorption. That extra step slows absorption and reduces efficiency.

What the Research Shows on Krill Oil and Knee Osteoarthritis

The differences in absorption and stability help explain why krill oil is being studied for more than just heart and metabolic health. Beyond improving how omega-3s are delivered to your cells, researchers have begun asking whether these benefits translate into relief for conditions linked to chronic inflammation, such as osteoarthritis.

That’s where the next study comes in — a closer look at how krill oil performs for people struggling with knee pain and mobility challenges. The study, published in Medicine (Baltimore), pulled together data from five randomized controlled trials involving 730 people diagnosed with knee osteoarthritis.4 The researchers wanted to see whether krill oil supplements were effective at relieving symptoms like pain, stiffness, and difficulty with daily movement.

• Study participants were mostly middle-aged and older adults — The people included in these trials were adults aged 30 to 85 years with mild to moderate knee osteoarthritis.

Some had additional issues like cardiovascular disease or rheumatoid arthritis, but the main focus was on knee pain and reduced mobility from osteoarthritis. Participants received krill oil in doses ranging from 2 to 4 grams per day, while control groups received placebos such as vegetable oils or inactive capsules. Treatment lasted from one month to 24 weeks, depending on the trial.

• Krill oil improved WOMAC stiffness, pain, and function — though the pain evidence was mixed — On the WOMAC index, krill oil was associated with statistically significant improvements in pain, stiffness, and physical function versus controls.
The pain evidence was mixed, however: The improvement did not reach statistical significance on the separate visual analog scale, and the authors concluded that krill oil’s effect on pain relief warrants additional investigation. They described krill oil as a promising option for knee osteoarthritis, with the optimal dose still to be determined.

• Side effects were rare and showed no difference from controls — When researchers looked at side effects, they found no significant differences between krill oil and placebo groups. Safety was comparable — krill oil did not cause more adverse effects than standard care. This reinforces the idea that krill oil is safe for most people when taken in typical doses.

• Possible mechanisms include anti-inflammatory and antioxidant effects — Scientists believe the benefits of krill oil stem from its high content of omega-3 fatty acids (EPA and DHA) and the antioxidant astaxanthin. Omega-3s may reduce the activity of inflammatory pathways in your body, which lowers the release of chemicals that drive joint swelling and pain.

Astaxanthin adds an extra layer of protection by neutralizing free radicals — unstable molecules that damage joint tissues and worsen osteoarthritis. Together, these compounds create a protective environment that may slow down joint damage and ease symptoms.

Krill Oil Supports Smoother, Better-Hydrated Skin in 12 Weeks

Krill oil’s benefits also extend to your skin. In a study published in the Journal of Cosmetic Dermatology, researchers ran two placebo-controlled pilot trials testing 1 and 2 grams of krill oil per day for up to 12 weeks.5 The goal was straightforward: does daily krill oil improve transepidermal water loss — a marker of skin barrier strength — surface hydration, elasticity, and the omega-3 index compared with placebo?

One important caveat: This skin research was funded by a krill-oil manufacturer (Aker BioMarine), two of its authors are employees of that company, and the company supplied the krill and placebo capsules. The two trials were also small pilot studies in healthy adults, so the findings await independent confirmation.

• Omega-3 status rose and skin barrier loss fell — Krill oil significantly raised the omega-3 index versus placebo in both studies. The authors noted “dose-dependent improvements” in skin barrier strength, hydration, and elasticity compared to placebo. While benefits were seen for both groups, they were greater at 2 grams per day.

• Hydration and elasticity improved meaningfully — Compared with placebo, hydration increased at 12 weeks, and elasticity rose, with large effect sizes, indicating robust, visible changes in skin properties. In other words, skin held water better and bounced back more readily. Gains emerged by week six and continued to week 12.

• Mechanisms likely involve membrane lipids, ceramides, collagen, and hyaluronic acid — The authors noted krill oil’s EPA/DHA in phospholipid form supports membrane structure and may influence barrier lipids like ceramides; Preclinical work cited in the paper links krill oil to higher skin collagen and hyaluronic acid gene expression and protection from ultraviolet-B-induced inflammation, aligning with the human improvements in skin barrier strength, hydration, and elasticity.

For normal-to-slightly-dry skin, 1 to 2 g/day krill oil for 12 weeks was associated with improved barrier strength, increased moisture, and improved elasticity, with larger gains at 2 g/day and outcomes tied directly to rising omega-3 index — an objective marker you can track.

Krill Oil and Liver Fat: Findings from an Animal Study

Researchers have also studied krill oil and liver fat, though so far in animals rather than people. Published in Nutrients, a mouse-and-cell study tested Antarctic krill oil against a high-fat diet to see whether it curbs fatty liver and oxidative stress, while also mapping the exact liver signaling pathways involved.6 Male mice were fed a high-fat diet for 60 days and received krill oil at 400 mg/kg per day.

• Liver fat dropped and “bad” lipid patterns eased — Compared with high-fat diet alone, krill oil lowered liver triglycerides and reduced visible liver fat. Blood lipids shifted in a favorable direction alongside improved atherogenic indexes that estimate artery risk.

• Krill oil helped the liver fight damage from stress — Eating a high-fat diet caused more “wear and tear” inside the liver by raising harmful byproducts (MDA) and lowering the activity of protective enzymes. Krill oil reversed this trend: it lowered MDA and boosted the activity of key liver defenses. That means less damage and stronger protection in the organ that processes most of your fat.

• Lab tests showed how krill oil interacts at the enzyme level — Computer modeling revealed that compounds in krill oil — including astaxanthin, EPA, and DHA — physically fit into the cholesterol-making enzyme in ways that explain why it slows cholesterol production. This provides a biological explanation for the cholesterol-lowering effects seen in the study.

• Fat storage outside the liver trended down as well — Krill oil cut down belly fat in mice fed a high-fat diet, suggesting it doesn’t just help your liver but may also improve how fat is stored across your body.

Note: The liver fat findings are from animal research and may not directly apply to human health. The remaining findings are from research conducted in clinical settings; results may not apply to all individuals.

Practical Steps to Make Omega-3s Work Better for You

If you’re trying to decide between fish oil and krill oil, it helps to know how differently they work in your body. Fish oil delivers omega-3s attached to triglycerides, while krill oil carries them in phospholipids — the same fats that make up your cell membranes.

That simple difference means krill oil slips into your cells more easily and delivers its benefits more efficiently. On top of that, krill oil contains astaxanthin, a natural antioxidant that keeps the oil stable and resists rancidity, something standard fish oils struggle with. Here’s how you can put this knowledge to use.

1. Choose krill oil for better absorption and added protection — If you’re taking omega-3s in supplement form, consider krill oil. Its phospholipid-bound EPA and DHA integrate directly into your cell membranes, which means your body makes better use of every milligram. In animal research, krill oil improved liver fat levels and lowered oxidative stress in just two months.7 You also get the astaxanthin, which helps make krill oil less likely to go rancid compared to fish oil.

Keep the Omega-3 Paradox in mind, though: More is not better. Daily omega-3 supplementation above about 1 gram has been linked to an increased risk of atrial fibrillation, especially in people with pre-existing heart conditions.8 Favor lower doses and whole-food sources, and increase your intake only under the guidance of your health care provider.

2. Focus on omega-3-rich whole foods — If you’d rather rely on your plate instead of a capsule, focus on wild-caught fatty fish such as Alaskan salmon, sardines, anchovies, and mackerel. These foods naturally deliver omega-3s in a balanced form that supports inflammation control and helps your liver handle fat more effectively. Eating fish a few times a week is one of the simplest, most natural ways to keep your omega-3 status strong.

3. Skip cheap fish oils that work against you — If you’re grabbing a bargain bottle of fish oil, you may be doing more harm than good. Many low-quality oils oxidize quickly, especially if they’re stored in warm or bright conditions. Once oxidized, fish oil produces compounds that fuel inflammation instead of calming it. Krill oil is naturally protected by astaxanthin, which keeps it stable and safe to use over time.

4. Avoid overdoing your intake — If you think more omega-3 is always better, think again. High-dose supplements — especially fish oil — have been linked to increased risks such as atrial fibrillation, a dangerous heart rhythm disorder.9 You don’t need megadoses to see real benefits. A food-first approach paired with a moderate amount of krill oil is enough to support your heart, brain, and liver without tipping into risky territory.

5. Clean up your fat sources to let omega-3s work — If you’re still eating ultraprocessed foods loaded with seed oils like soybean, canola, corn, or sunflower oil, you’re making it harder for omega-3s to do their job. These oils flood your system with linoleic acid, which may worsen inflammation and crowd out omega-3 activity.
Replace them with healthier fats like grass fed butter, tallow, and ghee, while using krill oil or fatty fish as your main omega-3 sources. This shift removes the roadblocks and lets the benefits of omega-3s fully reach your cells.

FAQs About Krill Oil vs. Fish Oil

Q: Why are omega-3 fats so important for health?
A: Omega-3s are essential fats that your body can’t make on its own. They power everything from your heart rhythm to brain function. You need to get them from outside sources like fatty fish or supplements such as fish oil and krill oil.

Q: How is krill oil different from fish oil?
A: Krill oil carries omega-3s in phospholipids, which match the structure of your cell membranes, making absorption more efficient. Fish oil usually delivers them in triglyceride or ethyl ester forms, which require more processing before your body can use them.

Q: What does the research say about krill oil’s absorption compared to fish oil?
A: A study in Food Chemistry: X found krill oil raised omega-3 blood levels more effectively at lower doses, while fish oil needed higher amounts to get similar results.10 Fish oil emulsions gave a quick boost but are more prone to rancidity, and high-dose fish oil carries risks like digestive upset and atrial fibrillation.

Q: Does krill oil help with joint pain from osteoarthritis?
A: The evidence is mixed. A meta-analysis in Medicine (Baltimore) reviewed five clinical trials with 730 participants. On the WOMAC index, krill oil significantly improved pain, stiffness, and function, but the improvement in pain did not hold up on a separate visual analog scale, and the authors concluded its effect on pain relief needs further study.11 Side effects were minimal and similar to placebo.

Q: Are there other benefits of krill oil beyond heart and joint health?
A: Research shows krill oil supports skin hydration and elasticity, strengthens your skin barrier, and reduces liver fat and oxidative stress in obesity models.12,13 These benefits come from its unique phospholipid omega-3s plus astaxanthin, a natural antioxidant that protects cells and prevents rancidity.

Everywhere you turn, chlorine is part of your environment, quietly embedded in your drinking water, shower steam, pool systems, and the cleaning products under your sink. It’s praised for its germ-killing power and assumed to be harmless in small doses. But the research on repeated, low-level contact is more nuanced than that — and there is a good deal you can do about it.

From the outside, chlorine looks like it’s doing its job: disinfecting, sanitizing, and sterilizing. But inside your body, it interacts with delicate tissues in ways researchers have linked to oxidative stress, irritation of your lungs and skin, and (in the case of its reaction byproducts) open questions about hormone signaling. You might brush off a sore throat after scrubbing a bathroom or chalk up itchy skin to “pool chemicals,” but those are worth paying attention to rather than ignoring.

People who work around chlorine, like lifeguards, janitors, and health care staff, often don’t realize how much cumulative contact a workday involves. Casual swimmers and children also report symptoms that seem unrelated at first, from cough to recurring skin rashes. Moreover, household tap water and cleaning routines add to the total exposure picture.

Understanding where chlorine exposure happens, how it affects different tissues and what habits make it worse is the first step to protecting your health. What you’ll see next are the ways this chemical interacts with your body — what the evidence supports, where it is thinner than headlines suggest, and the straightforward changes that reduce your exposure.

What the Research Links Chlorine to in Skin, Lungs, and Hormones

Chlorine exposure has been associated with several forms of irritation, and not only dry skin. Chlorine doesn’t stay stable in water — it reacts with organic materials like sweat, skin cells and urine to form toxic byproducts such as chloramines and trihalomethanes, which your body absorbs through your skin or inhales during swimming.1

• Chlorine byproducts are the focus of airway research — Indoor pools are a particular problem. Chloramines accumulate in the air when ventilation is poor, making you breathe them in deeply with every stroke. These airborne compounds irritate the airways, and occupational studies have reported increased airway reactivity among people with sustained exposure.

Reactive airways dysfunction syndrome (RADS), an asthma-like condition, has been documented in the toxicological literature — though the cases described there followed acute high-concentration incidents rather than routine pool use. The telltale “chlorine smell” is a practical signal that chloramines have built up in the air and ventilation is inadequate.

• Even brief exposure to pool water has been associated with eye irritation — A 2020 cross-sectional study of 96 swimmers aged 15 to 35 years old at a single university pool in Lampung, Indonesia, found that swimming for more than 15 minutes was associated with roughly 2.9 times the odds of eye irritation.2 Swimmers exposed to chlorine concentrations above the local regulatory standard had about 4.6 times the odds.

Because this is a single-site cross-sectional study, it shows association rather than cause, and the authors note that chlorine levels vary with dosing procedure, bacterial load, and weather.3 These effects are generally attributed to chlorine disrupting away the protective tear film on your eyes, leading to symptoms like redness, burning, and blurry vision.

• Your hair and skin take a hit after every swim — Chlorine can affect the skin’s barrier function, and people with eczema or sensitive skin appear to be more susceptible. A 2003 comparative study in The Journal of Dermatology immersed the forearms of 20 patients with atopic dermatitis and 10 control subjects in 40 degrees Celsius water at 0, 0.5, 1.0, and 2.0 mg/L residual chlorine.

Water-holding capacity of the stratum corneum (the outermost layer of the epidermis) decreased significantly at 0.5 mg/L or higher in the atopic group. In the controls, the effect appeared only at 2.0 mg/L. The study measured barrier hydration, not inflammation, and the authors suggest chlorine may play a role in exacerbating atopic dermatitis.4 The result is more itching, redness, and even flares of eczema or pool-related dermatitis.

Your hair isn’t immune either — chlorine is hard on it. Chlorine binds to hair proteins like keratin and dissolves the natural sebum that keeps your hair strong and shiny.5 This leaves strands brittle, dry, and prone to breakage and split ends. Blonde hair is especially vulnerable, often turning green due to the oxidation of copper in pool water.

• Chlorine reacts with sunscreen to create byproducts of largely unknown toxicity — In a 2020 paper published in Environment International, researchers noted that chlorine reacts with avobenzone (a common ingredient in chemical sunscreens) creating chlorinated phenols and acetophenones (acetylbenzene compounds).6

Note that this was a laboratory chemical analysis — gas chromatography–mass spectrometry work plus samples from two Slovenian pools — and it identified more than 60 byproducts.

Here, the authors state plainly that “the toxicity of the majority of these products remain unknown,” while noting that chlorinated phenols and acetophenones are recognized as relatively toxic. Bacterial luminescence testing showed the chlorinated mixtures were more toxic than unreacted avobenzone.7

• Chloramines, more than chlorine itself, are the harder problem — While chlorine itself is a strong disinfectant, it’s the compounds formed when it reacts with organic matter that account for much of the irritation research. These secondary byproducts are more likely to be inhaled or absorbed, and they don’t dissipate quickly — especially in indoor pools with stagnant air. That makes ventilation and post-swim rinsing more useful levers than most people assume.

What the Toxicological Profile Reports at the Cellular Level

According to the Toxicological Profile for Chlorine from the Agency for Toxic Substances and Disease Registry (ATSDR), chlorine is classified as a highly reactive and corrosive gas that damages tissue on contact.8

Even short bursts of high exposure cause immediate injury to your respiratory tract. For people working in water treatment, public sanitation, pool maintenance, or chemical manufacturing, the risk is especially relevant. Swimming or bathing in chlorinated water contributes at much lower concentrations.

• What the profile does and does not conclude about long-term low-dose exposure — The ATSDR profile is more cautious than most secondary coverage of it.

On chronic low-to-moderate exposure it states that “the preponderance of the evidence suggests that no serious long-term respiratory alterations result from acute exposure to low to moderate (up to approximately 20 ppm) concentrations of chlorine gas,” and its long-term occupational studies showed no clear dose-response relationship for respiratory endpoints.9

The profile does document persistent findings at the higher end: airflow obstruction and increased bronchial reactivity in some studies, and bronchial hyperresponsiveness persisting up to 30 months after accidental high-concentration releases. Occupational “gassing” studies found a higher prevalence of obstructive patterns and airway hyperresponsiveness.

Overall, the honest summary is that the evidence is mixed, stronger for repeated higher-concentration exposures than for everyday low-level contact, and that this is an argument for reducing avoidable exposure rather than for alarm.10

Hospital janitors, gym staff, university maintenance crews, and those working in sewage or water treatment are among the most regularly exposed groups.11 Unlike people who choose to swim, these workers often handle chlorine directly, clean with it, or breathe it in from treated surfaces and air systems without adequate protection.

• Chlorine reacts readily with moist tissues in your eyes, mouth and lungs — When inhaled, chlorine reacts with water to form hydrochloric and hypochlorous acids, both corrosive. The ATSDR profile documents this chemistry in water directly; its application to the respiratory tract is described there as a proposed mechanism rather than a confirmed one.

What is well-documented clinically is the symptom picture: burning sensations, coughing, chest tightness, and, in some cases, delayed-onset breathing difficulties.

• Your airways are the first line of contact — The ATSDR notes that damage often begins in your upper airways, with irritation of your nose and throat, then spreads to the tiny air sacs where oxygen exchange happens. In the more severe exposure cases the profile describes, recovery of symptoms did not always mean full recovery of function; RADS persisted for months in some patients. These outcomes are documented after significant exposures, not after routine swimming.

In some of these studies, exposed individuals showed heightened airway responses — lungs that react to small irritants like dust or cold air. The pattern resembles asthma without an allergic trigger. The ATSDR profile also records studies that found no such effect, so this should be read as a documented possibility at meaningful exposure levels rather than an established consequence of everyday contact.

• Unlike many pollutants, chlorine doesn’t just enter your body; it forms new compounds along the way — Chlorine doesn’t float passively through your system. Once inhaled or absorbed, it chemically transforms into reactive species that can stress the tissues they contact.

The ATSDR profile documents that chlorine oxidizes tissue sulfhydryl groups in the respiratory mucosa, and that antioxidant pretreatment reduced lung injury in an animal study — both consistent with oxidative stress playing a role.

It is worth adding bioenergetic context, though. Oxidative stress of this kind is one of the pathways through which environmental exposures are thought to erode mitochondrial energy production, and cellular energy output is the foundation your body repairs and defends itself from. That is the practical reason to reduce an avoidable chemical load rather than absorb it daily.

• The most severe cases occur when chlorine is mixed with other common chemicals — A key risk outlined in the report involves household or industrial settings where chlorine is accidentally mixed with ammonia or acidic cleaners.

This produces chloramine gas, a highly dangerous compound that can cause rapid-onset respiratory distress and, at high concentrations, respiratory failure. This is the one scenario that is a genuine emergency rather than a cumulative-exposure concern — never mix bleach with ammonia-based or acidic cleaners.

Many people clean their homes with bleach-based products in closed spaces like bathrooms or kitchens. Without fans or open windows, that gas accumulates quickly. Ventilation is the simple fix, and it matters most in small, enclosed rooms.12

Simple Swim Habits That Protect Your Skin from Chlorine Damage

Coach Slava Fattakhov, a former professional swimmer and coach, published a step-by-step skin protection guide on his website designed for swimmers, families and anyone regularly exposed to pool water. Note that the guide is practical experience rather than clinical research, so treat it as coaching advice.13 His goal is clear: help people swim often without sacrificing their health.

• Hydrating your skin before swimming makes it less absorbent to pool chemicals — Coach Slava recommends rinsing your body with clean, chlorine-free water before entering the pool — not just for hygiene, but to protect your skin. This initial rinse saturates your skin cells with clean moisture, which he reasons leaves less capacity to take up chlorinated water. While the mechanism is plausible, it hasn’t been formally tested, but the habit only costs a couple of minutes either way.

• Using a barrier cream or natural oil helps seal in moisture — Applying a layer of protection before swimming helps. Coach Slava suggests coconut, jojoba, or sweet almond oil. I suspect pure lanolin or tallow would perform better. Either one forms a physical layer between your skin and the water and slows chlorine’s ability to strip your natural oils. Lanolin is wool-derived, so skip it if you have a known wool-alcohol sensitivity.

• Getting chlorine off quickly is one of the most important steps — Right after your swim, rinse thoroughly with fresh water. Chlorine keeps reacting with your skin even after you leave the pool, so washing it off promptly limits how long that continues. The sooner you rinse, the less contact time chlorine has with your skin barrier.

• Locking in moisture after your swim speeds up recovery — Post-shower, apply a thick, nourishing moisturizer while your skin is still damp. Pure lanolin is a good choice here, and tallow works well, too. Both help restore your skin’s barrier function and retain hydration. This is especially important for frequent swimmers or anyone with dry or aging skin.

• Stay hydrated inside and out to maintain healthy skin — Internal hydration matters as well. Drinking pure, filtered water before and after swimming supports overall skin hydration, and well-hydrated skin generally tolerates irritants better than dry skin does.

Simple Ways to Protect Your Body from Chlorine Exposure

If chlorine exposure is drying out your skin, interfering with your breathing or making your eyes sting every time you swim, it’s time to change your routine. Whether you’re a swimmer, a parent of water-loving children or someone working around chlorinated environments, these steps will help you take control.
The good news is that chlorine exposure is one of the more controllable environmental variables in daily life. A handful of changes cut most of it out, and none of them are expensive or complicated. Here’s what I recommend:

1. Switch to a saltwater pool or skip indoor pools entirely — Chlorine exposure hits hardest when it’s concentrated and trapped, like in a steamy indoor pool. That “chlorine smell” is chloramines building up in the air.

Saltwater systems generate chlorine from salt electrolytically rather than dosing it in directly, which typically means lower free-chlorine levels and less chloramine odor — but they still produce chlorine and its byproducts, so they reduce exposure rather than eliminate it. If you have the option, outdoor saltwater pools are a much easier choice for your lungs, skin and eyes.

2. Apply pure lanolin as a pre-swim skin barrier — If you’re going to be in chlorinated water, coat your skin with pure lanolin or tallow first. Both create a thick, natural barrier, and both are preferable to petroleum jelly. This step helps hold moisture in and puts a physical layer between chlorinated water and your skin. If you’ve reacted to wool products before, use tallow rather than lanolin.

3. Install a whole-house water filter to reduce chlorine at home — You’re not just exposed to chlorine in pools — it’s also in your shower and tap water. That said, a high-quality whole-house filtration system can remove chlorine before it reaches your skin or lungs.

Inhaling chlorine steam during hot showers is a frequently overlooked route of exposure, since hot water volatilizes chlorine and the bathroom is usually the smallest, least-ventilated room in the house.

4. Rinse off before and after swimming — Always rinse with clean, fresh water before getting into the pool. Hydrated skin absorbs less chlorine. After you’re done, shower immediately using a natural, fragrance-free cleanser. Then, moisturize while your skin is still damp to lock in hydration. This two-step rinse routine reduces chlorine’s contact time and minimizes its irritating effects.

5. Avoid chemical sunscreens — Chlorine reacts with certain sunscreen ingredients like avobenzone to form chlorinated byproducts whose toxicity is largely uncharacterized. If you want sun protection while in the water, a natural mineral-based sunscreen is the better option. Clothing works too.

FAQs About Chlorine Exposure

Q: What are the long-term effects of chlorine exposure?

A: Long-term exposure to chlorine has been associated with irritation of the lungs, skin, and eyes, and occupational research has reported higher rates of airway reactivity and asthma-like conditions among heavily exposed workers.

Q: Where does chlorine exposure commonly happen?

A: Most people encounter chlorine through swimming pools, tap water, household cleaning products and workplaces like hospitals, gyms, and water treatment facilities. Indoor pools and poorly ventilated cleaning areas are especially risky because chloramines build up in the air where ventilation is inadequate.

Q: How does chlorine harm my body at the cellular level?

A: Once chlorine contacts moist tissues in your eyes, lungs, or skin, it forms corrosive acids that irritate and can injure cells. Toxicological data also point to oxidative stress — chlorine oxidizes sulfhydryl groups in respiratory tissue, and antioxidants reduced injury in animal work.

Oxidative stress of this kind is one of the pathways through which environmental exposures are thought to burden mitochondrial energy production, which is why lowering an avoidable chemical load is worth the small effort it takes.

Q: What steps can I take to protect myself from chlorine?

A: Use pure lanolin or tallow as a barrier on your skin before swimming. Shower with filtered water and moisturize immediately after. Avoid chemical sunscreens and use a high-quality whole-house filtration system to reduce chlorine in your drinking water and shower. Whenever possible, choose saltwater pools or swim outdoors, and never mix chlorine-based cleaners with other products.

Q: Who has the highest risk for chlorine-related health issues?

A: People working in sanitation, pool maintenance, hospitals, and gyms face the highest cumulative exposure, along with frequent swimmers and children. Anyone exposed to chlorine regularly, especially in poorly ventilated environments, should take steps to minimize contact and support skin, lung, and overall health.

None of this needs to keep anyone out of the water — swimming is excellent movement, and outdoor swimming pairs it with the sun exposure your mitochondria depend on. The goal is to enjoy it while keeping the chemical load low.

Estrogen dominance is one of the most misunderstood hormonal imbalances in modern medicine — and it’s costing people their energy, fertility, and peace of mind. You might be told your estrogen is low because your blood levels look normal or even depleted. But if you’re still battling mood swings, fluid retention, fatigue, or persistent inflammation, something deeper is going on.

What most people don’t realize is that hormones don’t just float through your bloodstream — they get trapped inside your tissues. And over time, this hidden buildup of estrogen quietly may disrupt everything from your thyroid to your immune function. Worse, it often shows up alongside rising levels of histamine, serotonin, and inflammatory endotoxins, creating a biochemical storm that conventional lab testing often misses.

This happens in women who can’t lose weight no matter what they eat. In men who feel drained, anxious, and foggy but are told their hormones are “fine.” In couples struggling with infertility while chasing normal blood results. The pattern is always the same: The labs don’t match the symptoms, and the treatments fall short.

If your intuition is telling you something’s off — even when the test results say otherwise — you’re not imagining it. The key is knowing where to look and how to measure what’s really going on. That’s where bioenergetic researcher Georgi Dinkov’s work comes in. He’s uncovering a deeper layer of hormone disruption that could explain exactly what’s keeping you stuck.

Estrogen Builds in Your Cells, Not Your Bloodstream

In the video interview above, Dinkov explained a significant blind spot in hormone testing: most doctors measure what’s circulating in your blood but not what’s building up inside your cells.1 Dinkov referenced a study analyzing hair samples from women, drawn from a cohort of 196 women ages 25 to 45.2

According to Dinkov, the study found that estrogen levels increased with age at the tissue level, while key protective hormones like progesterone, thyroid hormone (T3), pregnenolone, and DHEA steadily declined. Hair is made of dead cells and reflects long-term accumulation, which makes it a useful marker for what’s happening inside your tissues over months — not just in the blood for a single moment.

• Blood tests miss the full picture, leading to misdiagnosis — Dinkov emphasized that conventional lab testing fails to detect estrogen overload because blood levels don’t reflect what’s stored in your tissues. Even though your ovaries are failing and blood estradiol levels drop, every other cell in your body can still make estrogen — and they do, he explained.

This means that symptoms like fatigue, swelling, breast tenderness, and even breast cancer are often still estrogen-driven, even when your labs show low estrogen. Blood tests are only showing what’s circulating, not what’s stuck in your tissues, and that’s where estrogen may cause harm.

• Symptoms of estrogen dominance are wrongly blamed on deficiency — Many women are told they need estrogen replacement because their blood levels appear low. But Dinkov warned, “The most popular kind of breast cancer is estrogen receptor-positive. How can you have an estrogen-driven disease if you’re deficient in estrogen?”

He pointed out that tissue estrogen is often high in menopausal women, and that hormone therapy based solely on bloodwork often makes things worse. Estrogen dominance symptoms — like water retention, fatigue, insomnia, and infertility — aren’t signs of deficiency. They’re signs your body is overloaded, and your doctor just isn’t seeing it.

• Hair and nail testing offer a better picture of long-term hormone exposure — According to Dinkov, each half-inch of hair growth reflects about one month of internal biochemistry. This makes it a powerful tool for uncovering chronic hormonal imbalances. Unlike bloodwork, which only captures a moment in time and fluctuates wildly based on stress or food intake, hair and nail analysis shows trends, giving you data you can actually act on.

Tissue Testing Reveals Patterns That Explain Unresolved Health Issues

Dinkov described how many people come to his lab saying, “Something’s not right, but my doctor says all my tests are normal.” In many cases, he finds hidden overloads of estrogen, serotonin, or heavy metals like lead, cadmium, and titanium. Titanium dioxide is in many drugs and supplements, and even tiny doses may increase diabetes risk, he said. Because these substances build up gradually, they’re often missed by blood tests but are detectable in hair or nail analysis.

• Serotonin and histamine track closely with estrogen in stressed or inflamed states — Dinkov noted that elevated serotonin and histamine often show up alongside estrogen in hair and nail samples. These biochemicals all share overlapping pathways that reflect systemic stress and immune activation, he explained.

High serotonin levels are often falsely celebrated as good, but chronically elevated serotonin contributes to inflammation, suppressed metabolism, and gut dysfunction. Similarly, histamine overload mimics allergy symptoms or anxiety, but it’s often a byproduct of deeper biochemical chaos linked to estrogen overload.

• Declining thyroid hormone worsens estrogen buildup — Thyroid hormone T3 plays a key role in metabolizing estrogen and clearing it from tissues. In the study referenced by Dinkov, T3 levels steadily declined with age, right alongside progesterone and DHEA.3

This sets the stage for estrogen to accumulate, because your body lacks the metabolic drive to get rid of it. When thyroid output slows down, estrogen builds up faster, and has been associated with a range of effects, from low energy to mood instability to abnormal cell growth.

• Blood test snapshots miss the bigger picture — Dinkov shared that steroid levels fluctuate minute-by-minute, especially during stressful doctor visits. Some people get nervous and their cortisol spikes, others feel fine at the clinic but are actually under chronic stress the rest of the time.

What matters isn’t your hormone levels during a 10-minute appointment — it’s the pattern over weeks or months. That’s what hair shows you. With each strand, you can trace your biochemical state month by month, uncover what triggered past symptoms, and start making informed changes that actually match your biology.

How to Stop Estrogen, Histamine, and Serotonin from Hijacking Your Health

If your hormones feel “off,” but your labs keep coming back normal, it’s not your imagination — it’s the testing. What’s in your blood isn’t always what’s in your tissues.

Most hormone panels miss the estrogen, serotonin, and histamine that get stuck inside your cells, where they quietly may affect your energy, fertility, mood, and metabolism. If you’re stuck in that frustrating loop — bloated, wired, exhausted, or inflamed — it’s time to shift your strategy. Here’s how to get to the root of what’s actually happening and start undoing the damage.

1. Start with a tissue-level test and get your prolactin checked — If you’ve been told your estrogen is low but still feel estrogen-dominant, you need a better way to measure what’s really happening. Hair or nail analysis gives you a timeline of hormone buildup in your tissues, month by month, allowing you to track stored estrogen, serotonin, cortisol, and even heavy metals.

On top of that, check your prolactin levels. High prolactin is a marker of excess estrogen activity, even when your estrogen looks low on a blood test. If your prolactin is elevated and your thyroid is low, that’s a red flag your cells are swimming in estrogen. This step alone helps you stop chasing the wrong diagnosis and finally start correcting the right imbalance. Talk to your healthcare provider about whether this testing is appropriate for you.

2. Eliminate the things that mimic estrogen — Most people are unknowingly loading their bodies with estrogen-like chemicals from everyday products. Vegetable oils — like canola, soybean, and sunflower — are high in linoleic acid (LA), which promotes estrogen dominance by potentially impairing thyroid function, slowing estrogen detox, and reducing mitochondrial energy production.

Keep your LA intake between 2 and 5 grams per day — the historical norm before industrial seed oil consumption rose, and a level your body still needs for healthy mitochondrial function.

At the same time, ditch endocrine-disrupting chemicals (EDCs) lurking in plastics, personal care products, and cleaning supplies. Swap out anything with parabens, phthalates, and synthetic fragrance. Store food in glass. Drink from stainless steel or glass bottles. Don’t microwave food in plastic, and filter your tap water to reduce microplastic exposure.

3. Stop feeding the gut bacteria that keep this cycle going — Estrogen, histamine, and serotonin all get recycled and amplified in your gut, especially if you’re overfeeding oxygen-tolerant bacteria. Beans, leafy greens, cruciferous veggies, and whole grains all ferment quickly and feed the wrong microbes when your gut is compromised.

That drives more bloating, inflammation, and gas. If you have a damaged gut, focus on whole fruit and white rice, which digest cleanly without fermenting too fast. Then, gradually introduce higher-fiber foods that you can tolerate.

Avoid high-histamine foods (like fermented vegetables, leftover meats, or aged cheeses) while your system resets. You’ll also want to support liver detox with collagen-rich foods like gelatin or bone broth — this helps clear out excess histamine and serotonin before they build up in your tissues again.

4. If you’re using hormonal therapies, reassess your load — If you’re on estrogen-based hormone replacement therapy (HRT) or birth control, step back and look at the bigger picture. Bioidentical or not, you’re still adding to your estrogen load. And if your tissues are already saturated, more estrogen — especially without enough progesterone to balance it — just adds fuel to the fire.

Consider switching to natural methods that support your body’s own hormonal rhythm. If you’re in perimenopause or menopause, natural progesterone is especially helpful. It opposes estrogen, stabilizes your mood, and supports your thyroid. This isn’t about giving up support — it’s about choosing the kind that restores your body instead of flooding it.

5. Clear out the estrogen you’ve already stored — To lower your tissue estrogen load, support your body with natural progesterone. Progesterone acts as a natural antagonist to estrogen, helping to balance its effects. Given the tendency toward estrogen dominance, incorporating natural progesterone may help restore a more balanced hormonal ratio.

Once you shift your focus to what’s happening inside your tissues — and not just what shows up in your blood — you’ll finally understand why the old strategies stopped working. And more importantly, you’ll know exactly what to do next.

FAQs About Estrogen, Histamine, Serotonin, and Endotoxin

Q: Why do my hormone blood tests say I’m low in estrogen, even though I feel estrogen dominant?
A: Because blood tests only measure what’s circulating at that moment — not what’s trapped inside your tissues. Estrogen often builds up inside cells, where it continues to exert strong biological effects. If you’re experiencing symptoms like fatigue, breast tenderness, water retention, or mood swings, you’re likely dealing with high tissue estrogen, even if your lab work says otherwise.

Q: How do histamine, serotonin, and endotoxin relate to estrogen overload?
A: These compounds often rise together and create a compounding effect. Elevated histamine and serotonin worsen symptoms like anxiety, gut issues, and sleep problems. Endotoxins, which come from gut bacteria, amplify the cycle by driving inflammation and hormonal disruption. Estrogen slows gut motility, which increases endotoxin exposure, setting off a cascade of biochemical stressors.

Q: What’s the most accurate way to measure what’s happening with my hormones?
A: Hair and nail analysis may provide a timeline of your tissue hormone levels over weeks or months, something blood tests can’t capture. This method reveals chronic overloads of estrogen, cortisol, serotonin, and even heavy metals, giving you actionable insights into what’s really going on inside your body.
In addition, prolactin is a useful marker of estrogen activity, since estrogen stimulates prolactin production. If your prolactin is high, especially alongside low thyroid, it’s a strong sign that your estrogen load is elevated at the tissue level.

Q: What can I do to lower my estrogen load and feel better?
A: Start by removing vegetable oils (like soybean and canola), which promote estrogen dominance, and avoid endocrine-disrupting chemicals found in plastics and personal care products. Support detox with collagen-rich foods and avoid high-histamine or fermentable foods that feed harmful gut bacteria. Use natural progesterone to help counter estrogen’s harmful effects and support hormonal balance.

Q: Should I be using estrogen-based therapies like birth control or HRT?
A: If your tissues are already overloaded with estrogen, adding more — even if it’s “bioidentical” — worsens the imbalance. Estrogen-based therapies should be reassessed, especially if you’re dealing with unresolved symptoms. Natural progesterone is a safer, more supportive option for rebalancing your hormonal ratio and protecting your thyroid and metabolism.

Vestibular migraine is a neurological condition that affects your balance system, often without producing the severe head pain most people associate with migraine. That distinction is exactly why it goes unrecognized so often. When dizziness is the primary symptom and headache doesn’t occur, neither patients nor physicians think to connect what they are seeing to migraine at all.

This single blind spot explains an enormous amount of unnecessary suffering. People cycle through emergency rooms, ENT offices, and anxiety diagnoses while the actual disorder hides behind symptoms that, taken individually, each look like something else. The pattern is remarkably consistent: each complaint is evaluated in isolation, so no one steps back far enough to see that a single condition ties them together.

Unlike disorders that damage the inner ear itself, vestibular migraine affects the way your brain processes balance and sensory information. Left untreated, attacks interfere with work, driving, travel, and everyday activities, while constant uncertainty often adds another layer of emotional stress.

The good news is that researchers have learned much more about why this disorder develops, why it’s so commonly misdiagnosed, and what clues separate it from other causes of dizziness. Those discoveries begin with a closer look at why vestibular migraine remains hidden in plain sight.

Many People with Vestibular Migraine Spend Months Chasing the Wrong Diagnosis

Despite affecting millions of people, vestibular migraine remains one of the least recognized neurological disorders, a problem a New York Times feature explored in detail.1 The greatest barrier isn’t a lack of symptoms but a failure to recognize what those symptoms mean.

• Many people receive several incorrect diagnoses before anyone identifies vestibular migraine — The article followed Alicia Wolf, whose symptoms began after an overseas trip while she was recovering from a cold and coping with intense work stress. As her dizziness worsened, she developed severe light sensitivity, sound sensitivity, and difficulty using a computer, yet each symptom was treated separately instead of being connected to a single neurological disorder.

An emergency physician diagnosed vertigo, but vertigo is only the sensation of spinning, not the disease itself. It took five months before she finally received the diagnosis that explained everything she had been experiencing.

If you’ve been told your dizziness comes from anxiety, stress, or an unexplained balance disorder, it’s worth asking whether those explanations account for every symptom you experience. The article repeatedly showed that focusing on one complaint at a time often delays the correct diagnosis.

• Vestibular migraine often falls between two medical specialties — Dr. Jeffrey Sharon, an associate professor of otolaryngology at the University of California, San Francisco, explained that the condition occupies “a forgotten corner of medicine” because neurologists usually treat migraine while ear specialists evaluate balance disorders. Patients frequently move between both specialties before someone recognizes that migraine is driving the symptoms.

Sharon called vestibular migraine “the most common disease you’ve never heard of.” He explained that disorders such as Ménière’s disease and persistent postural-perceptual dizziness often resemble vestibular migraine, making diagnosis more challenging.

Formal diagnostic criteria weren’t established until 2012, and according to Cynthia Ryan of the Vestibular Disorders Association, awareness continues to improve even though many clinicians remain unfamiliar with the condition.

• Recognizing the pattern is the first step toward effective treatment — Once specialists connected Wolf’s symptoms under a single diagnosis, her treatment changed completely. Instead of chasing one symptom after another, she received a plan tailored to vestibular migraine, illustrating why identifying the underlying disorder, not simply treating dizziness, is often the turning point in recovery.

Tracking Your Symptoms Reveals the Triggers That Keep Attacks Coming

In an educational resource developed with Dr. Shin Beh, founding director of UT Southwestern Medical Center’s Vestibular and Neuro-Visual Disorders Clinic, the American Migraine Foundation explains how patients and physicians work together to recognize recurring symptom patterns, distinguish vestibular migraine from similar disorders, and build a treatment plan tailored to the individual.2

Rather than focusing only on diagnosis, the guidance emphasizes daily habits that help reduce attacks and improve quality of life.

• The guidance focuses on people whose dizziness interferes with normal life — According to the Foundation, vestibular migraine affects up to 3% of adults and occurs up to five times more often in women than men. Beh notes that many patients are women in their late 30s or 40s with a history of migraine headaches, motion sickness, or a family history of migraine.

Their symptoms commonly interfere with driving, work, travel, and other everyday activities, but identifying personal triggers often becomes the turning point toward better symptom control.

• Keeping detailed records helps uncover patterns that memory misses — Instead of relying on memory after an attack, the Foundation encourages tracking each episode as it happens. Every entry provides another clue about what happened before symptoms started and what circumstances surrounded the attack. Over time, those details often reveal patterns that are impossible to recognize by memory alone and make it easier to build a treatment plan that addresses your specific triggers.

• Common triggers vary from one person to the next — Beh identifies weather changes, poor sleep, emotional stress, menstrual cycle changes, bright or flashing lights, skipped meals, caffeine, chocolate, and alcohol among the most frequently reported triggers. The important lesson is that your trigger pattern is unique.

Finding the factors that repeatedly precede your attacks is far more valuable than assuming someone else’s trigger list applies to you. The Foundation recommends keeping a symptom journal to record what you ate, how well you slept, your stress level, how long symptoms lasted, and any unusual events that occurred before each episode.

• Several overlooked symptoms help distinguish vestibular migraine from other balance disorders — In addition to dizziness, the Foundation highlights brain fog, fatigue, word-finding difficulty, dry mouth, sweating, diarrhea, excessive yawning, tingling, scalp tenderness, and blurred vision as clues that point toward vestibular migraine.

Childhood motion sickness also provides an important clue because many patients describe unusual sensitivity to car rides, boats, or amusement rides years before their migraine symptoms appeared. Likewise, grocery stores, shopping malls, scrolling quickly on a phone, or visually busy environments often make symptoms worse, giving patients additional clues to record in their journals.3

• Comparing your symptoms with similar disorders helps narrow the diagnosis and guide treatment — Benign paroxysmal positional vertigo (BPPV) usually causes spinning episodes lasting less than one minute after specific head movements, while vestibular migraine episodes often continue for minutes, hours, or even days. Ménière’s disease, by comparison, usually produces hearing loss, ringing in one ear, or ear pressure that doesn’t define vestibular migraine.

Beh emphasizes that treatment is never one-size-fits-all, stating, “The key is to find what works for you.” Depending on the individual, conventional treatment often combines lifestyle changes with vitamin B2, magnesium, coenzyme Q10 (CoQ10), prescription medications, or neuromodulation devices. Consistently tracking symptoms and making gradual adjustments gives you an active role in reducing future attacks instead of simply reacting to them after they begin.

Supporting Your Nervous System Health When You Have Vestibular Migraine

Rather than focusing only on stopping the dizziness, it’s important to figure out what repeatedly pushes your nervous system into an attack. Vestibular migraine rarely appears out of nowhere. Most people develop recognizable patterns, and once you identify them, you gain far more control over your symptoms.

A reasonable goal is to support your nervous system health by encouraging healthy cellular energy production while identifying and reducing the triggers that may contribute to sensory overload.

1. Lower your linoleic acid (LA) intake to support healthier mitochondria — If you make only one dietary change, I recommend starting here. Excess LA, the primary polyunsaturated fat in seed oils, may compromise the integrity of inner mitochondrial membranes where energy production takes place, potentially leaving your brain cells short of the energy they need to process sensory information normally.

It may also mimic estrogen in the body, potentially contributing to estrogen dominance. That hormonal effect may help explain why vestibular migraine disproportionately affects women, particularly during their late 30s and 40s when estrogen levels are already fluctuating.

Estrogen may influence how readily your nervous system relays pain and sensory signals.4 When estrogenic activity rises, whether from hormonal shifts or from external sources, those neurons may fire more easily in response to motion, light, and sound. This is also why menstrual cycle changes rank among the most commonly reported triggers: the same hormonal swings that drive a normal cycle can push an already-sensitized nervous system past its threshold.

I recommend keeping your LA intake below 5 grams per day, and ideally 2 grams, by removing soybean, corn, sunflower, safflower, canola, and cottonseed oils from your diet. That also means avoiding most processed foods and restaurant meals, where these oils are widely used. Instead, prepare food with more stable fats such as grass fed butter, ghee, or tallow.

If you want an easy way to monitor your intake, food-tracking tools with seed oil detection features, such as the Seed Oil Sleuth in the Pax health platform, can help identify hidden sources of LA in your diet and estimate your total daily intake.

2. Reduce the three vestibular migraine triggers that commonly stack together — The sources consistently point to stress, poor sleep, and inflammation as major drivers of vestibular migraine. Rather than trying to eliminate every possible trigger, focus on the ones you control every day.

Build a consistent sleep schedule, plan your diet around whole foods, give yourself recovery time after busy workdays or travel, and identify situations that repeatedly overload your senses. Small daily improvements often produce larger long-term results than dramatic short-lived changes.

3. Give your mitochondria the nutrients they need to produce energy — Frequent migraine attacks often reflect cells that struggle to produce enough energy efficiently. Vitamin D supports healthy nerve signaling and has been studied for its role in modulating inflammatory responses.5 Some researchers have explored whether maintaining adequate vitamin D levels may be relevant for people who experience migraine.6

B vitamins, including riboflavin (vitamin B2), folate, vitamin B6, and vitamin B12, help convert the food you eat into usable cellular energy. Magnesium helps calm overactive nerve signaling, while CoQ10 supports the electron transport chain, the sequence of reactions inside mitochondria that generates most of your cells’ energy.

That energy supply matters directly for vestibular migraine because your brain’s balance-processing centers are among the most energy-demanding structures in your nervous system.

When those neurons struggle to produce energy efficiently, they may become more sensitive to normal sensory input, potentially interpreting routine signals from your eyes, inner ears, and muscles as overwhelming, which may contribute to the sensory overload and dizziness characteristic of vestibular migraine.

Increase magnesium-rich foods such as leafy greens whenever possible. If you use a magnesium supplement, well-absorbed forms such as magnesium glycinate or malate may support cellular uptake. In clinical settings, health care providers have explored the use of intravenous magnesium as a supportive measure during severe migraine episodes.

4. Pay attention to your sensory environment — If bright lights, crowded stores, scrolling on your phone, loud environments, or long hours in front of a computer consistently make you feel worse, start treating those situations as warning signs instead of pushing through them.

I recommend planning short breaks before symptoms escalate. If you notice motion sensitivity while driving or shopping, write it down. Those details help reveal your unique pattern and help you avoid unnecessary attacks.

5. Find the right holistic specialist if your symptoms don’t fit the diagnosis you’ve been given — If you’ve been told you have anxiety, unexplained vertigo, or an inner ear disorder but your symptoms still don’t fully add up, don’t assume the search is over. Vestibular migraine frequently goes unrecognized because many attacks occur without headache.

I recommend keeping detailed records of your symptoms and bringing them to an integrative physician with experience treating migraine and balance disorders. The more complete your history becomes, the easier it is to connect symptoms that once appeared unrelated.

FAQs About Vestibular Migraine

Q: What makes vestibular migraine different from a typical migraine?
A: Vestibular migraine primarily disrupts your balance system instead of causing severe head pain. You may experience dizziness, unsteadiness, motion sensitivity, or a feeling that your surroundings are moving, even if you have little or no headache. Because many people expect migraine to mean headache, the condition is frequently overlooked or mistaken for an inner ear problem or anxiety.

Q: Why does it often take so long to receive the correct diagnosis?
A: Vestibular migraine shares symptoms with several other conditions, including inner ear disorders and anxiety-related dizziness. Because different symptoms are often evaluated separately by different specialists, the underlying neurological cause can remain hidden for months before someone recognizes the overall pattern.

Q: How can you identify what’s triggering your attacks?
A: Keeping a detailed symptom journal is one of the most effective ways to uncover personal trigger patterns. Recording factors such as sleep quality, meals, stress levels, weather changes, menstrual cycle changes, caffeine, alcohol, and visual or sensory exposures can reveal recurring connections that are difficult to remember after an episode has passed.

Q: What symptoms besides dizziness can point toward vestibular migraine?
A: Many people also experience brain fog, fatigue, blurred vision, sensitivity to light or sound, difficulty finding words, motion sickness, or discomfort in visually busy environments such as grocery stores or while scrolling on a phone. Looking at the full combination of symptoms often provides important clues that a balance disorder alone can’t explain.

Q: What steps may help reduce future vestibular migraine attacks?
A: Long-term improvement usually comes from identifying and minimizing your personal triggers while supporting overall nervous system health. Consistent sleep, stress management, avoiding dietary factors that worsen symptoms, tracking sensory triggers, and working with a knowledgeable clinician to develop an individualized treatment plan can all help reduce the frequency and severity of attacks over time.

Endocrinology is a branch of medicine that focuses on the study of hormones and the glands and tissues that produce them. It addresses the intricate balance of hormones that regulate many of your body’s essential functions, and how to keep them in the proper equilibrium. I interviewed U.K. clinician Keith Littlewood on this topic, revealing details that may be useful for understanding and supporting your endocrine health.

Littlewood, who splits his time between consulting with patients and completing a Ph.D. in endocrine research, bases much of his work on Ray Peat and has extensive clinical experience on how to improve energy, metabolism, digestion, sleep, fertility and other key foundations of optimal health.

The Importance of Understanding Thyroid Physiology

One of Littlewood’s areas of focus is looking at how endocrine disruptors affect thyroid physiology at the molecular level and the super molecular level. Of the many hormones in your body, thyroid hormones are perhaps the most important, as they regulate your metabolism and are required for nearly every physiological process in your body. When your thyroid levels are unbalanced, the effects can be wide-ranging.

Thyroid dysfunction has been associated in the clinical literature with a range of health issues, including fibromyalgia, irritable bowel syndrome, eczema, gum disease, and autoimmune disorders. However, observational associations of this kind do not establish that thyroid imbalance causes these conditions.

This is because your thyroid impacts various parts of your body, making the symptoms of dysfunction diverse. Your hypothalamus secretes thyrotropin-releasing hormone (TRH) that triggers your pituitary gland to release thyroid-stimulating hormone (TSH) that then causes your thyroid to release T4.

Approximately 90% of your thyroid hormone is released in the relatively inactive form T4, according to standard endocrinology references.1 Deiodinase enzymes then convert T4 into the active form, T3 — primarily in your liver and kidneys, though the conversion also takes place in other tissues. Thyroid problems may exist, however, even when standard thyroid function tests show normal results. Littlewood says:

“TSH can be just a completely redundant test for multiple reasons … even abundance of T4 can be problematic and stimulate certain pathways. And that’s really why … T3 should be being looked at as opposed to TSH because stressed people have generally suppressed TSH values.

Chronic dieters can have suppressed TSH values. There are hormone-disrupting chemicals in the environment that can suppress how thyroid function is being modulated.

And I think that makes it even more complex when a clinician would just look at TSH and T4 and go, ‘Well, your blood tests are completely normal, let’s move on to something else or it’s in your head.’ This is a common theme that I’ve seen well over a decade now with clients who’ve had their blood tests and just because they looked at these two markers, they’re euthyroid [normal thyroid function] rather than potentially hypothyroid.

… just looking at TSH and T4 on its own, it can be very muddy water to look into. That’s why the relatively crude test of temperature and pulse can be pretty useful. But again, you want other markers as well. You want cholesterol, you might want to look at prolactin, other hormone levels, you might want to look at lactate, all of these other markers that could be useful in getting you to understand what thyroid is actually doing.”

While people with subclinical hypothyroidism will often have normal lab work, low body temperature and pulse rate have long been used clinically as supporting signs worth investigating — though neither is diagnostic on its own. Also, a TSH toward the lower end of the reference range is often viewed favorably, but it can also be suppressed by cortisol and adrenaline — so, a low reading is not automatically reassuring. Checking your temperature and pulse after eating is one way to double-check that.

A cholesterol test can also be helpful. In the bioenergetic literature, elevated cholesterol (mid- to high-200s) is interpreted as a possible sign that the conversion of cholesterol into steroid hormones is sluggish, and low cholesterol is associated with infection. These interpretations are not established in conventional endocrinology and are best reviewed with a clinician who knows your history. If you decide to go on this route, talk to your health care provider about whether this testing is appropriate for you.

The Primary Causes of Thyroid Disruption

While there are dozens of factors that may disrupt thyroid function, Littlewood believes estrogen dominance and estrogen excess are among the primary causes.

“I think if we look to the major kind of cohort who tend to suffer the most, it’s women … estrogen will suppress thyroid function and when there’s an estrogen dominance and estrogen excess, it will suppress how much thyroid hormone is being produced,” he says. “This kind of state will need supplementing with thyroid hormone because thyroid hormone will help increase estrogen metabolism.”

That said, note that thyroid hormone is a prescription therapy. Whether it is appropriate, and at what dose, is a decision for a qualified clinician who can diagnose and monitor treatment — not something to start on your own.

Other factors, including diet and environmental pollution, also need to be addressed. “The diet becomes intricately involved with trying to resolve this. You can’t just throw thyroid hormones and expect that you’re going to, A, lose weight and B, resolve all those issues because if you don’t have enough energy in the tank, then you’re not going to be able to function at that point as well,” Littlewood says.

He mentions Brassica vegetables, such as cabbage, Brussels sprouts, broccoli and cauliflower, which contain thiocyanates that may suppress thyroid function in large quantities, as one example. However, he adds that environmental pollutants can also be damaging, particularly if you have a genetic predisposition for thyroid problems or your diet isn’t ideal. These factors can compound one another, in what Littlewood describes as a “perfect storm”:

“If you’ve got poor inheritable traits … your nutrition’s not in good order … you’re under lots of stress and you’re exposing yourself to certain endocrine disruptors … [via] food choices, certain pesticides, very polluted environments in the city, perhaps even wireless exposure … All of these things can create a perfect storm. So, it becomes almost like a clinical ecology exercise to start with.

What can you remove from your environment that might be damaging you? And that could be a thousand different things for a thousand different people. So that’s where it becomes quite useful to do your due diligence about what somebody needs. It’s a needs analysis to get people to where they want to be. There’s no point in just saying, ‘Hey, his thyroid hormone, everything’s going to work out right,’ because it never happens like that.”

Get Your Diet Right First

Many lifestyle factors can contribute to low thyroid function, including stress, inadequate light exposure and exposures to endocrine-disrupting chemicals. In terms of diet, high polyunsaturated fat (PUF) intake, including linoleic acid, is one factor that has drawn attention, as research suggests PUFs may interfere with your cells’ ability to use active thyroid hormone.

With so many factors affecting your endocrine health, where should you begin to get it all sorted out? Littlewood recommends targeting your diet first:

“One of the most common themes that I’ve found — and my practice is probably about 70% females overall — it’s getting enough protein in, it’s getting enough calories in, it’s getting enough carbohydrates in and making sure that you can utilize those carbohydrates quite well … what you should be able to do is utilize carbohydrates as a fuel, everybody should be able to do it.”

Low-carb diets may work against healthy thyroid function. For healthy thyroid function, you need to make sure T4 can be efficiently converted into T3.

To support the conversion of T4 to T3, focus on whole, unprocessed or minimally processed foods, with enough protein and easily digested carbohydrates that are less likely to cause intestinal irritation or endotoxin production — whole fruits and white rice are the usual starting points in this regard. Littlewood explains that he often sees issues among his patients who have followed low-carb diets:

“This is something that I’ve seen with lots of females coming in who’ve gone keto, they’ve gone carnivore and they’re experiencing more disturbed menstrual cycles, increased hair loss. You can see that they’re progesterone deficient. You see that estrogen taking a hold, and this is where it becomes problematic and you start to see the sleep, the digestion, the mood, energy, all of these things that tend to go out of whack.

So, I would say that the diet is the base for everybody to get that right. A lot of people are unsure of some of the chemicals that are around, and they tend to become more aware of that as the process goes on.

So, I do think it’s getting the diet right first of all. I think it’s becoming aware of the things that could potentially disrupt thyroid, decrease progesterone, increase estrogen, and then you could start to look at that straight away. But it’s certainly something, I often work for at least a month or two, getting the diet right before you even consider entertaining them to think about thyroid hormone.”

Fixing your gut health is also important. “Digestion goes hand in hand with thyroid. It goes hand in hand with regulating thyroid, absorbing thyroid from the gut as well, and also how to regulate insulin as well. And if you can’t digest your nutrients, you are always going to have a problem with supporting the thyroid,” Littlewood says.

The Estrogen Connection

As I noted in this interview, many people believe that they are low in estrogen due to bloodwork, when they actually have high levels in their organs. This is because serum estrogen levels are not fully representative of estrogen that’s stored in tissues. Estrogen can be low in plasma, but high in tissues.2,3,4 Littlewood agreed:

“Yep. I would concur with that. I mean, where is the highest amount of T3 found? The highest amount of T3 is found intracellularly. It’s not in serum. So if you apply that rationale to estradiol, for example, and maybe the other weaker estrogens like estrone and estriol, they are going to be in the tissues.

Now, bear in mind, if you have any amount of adipose tissue, you are generating estrogen by default, and the amount of aromatase that’s being produced will convert testosterone and other hormones also to estrogen. So looking at the serum test, I think urinary tests can be useful, but again, they have their pitfalls because they’re not representative of systemic tissue status of these hormones.”

Estrogen appears to inhibit the conversion of T4 to T3, and, in my view, excess estrogen is among the more significant contributors to cancer risk — a position that sits outside the conventional consensus. Many clinicians also assume serum levels are equivalent to tissue levels, which may not hold. If that is right, some people may be reassured by a low serum result while tissue exposure remains higher.

One indirect option some clinicians use to gauge estrogen activity in fat and tissues is a prolactin blood test, though prolactin is not a validated measure of tissue estrogen. With this in mind, estrogen promotes the production of prolactin, which is a hormone produced by the pituitary gland. If you decide to have it tested, talk to your health care provider whether it’s appropriate for you:

“Prolactin can be very, very useful. I think keeping prolactin round about 10 milligrams per deciliter is the general idea. I think the average reference range is anywhere from 20 up to a couple of hundred … when you start to see prolactin that high, you start to infer that there’re going to be some problems probably related to high estrogen.

Sometimes you can actually look at someone and tell whether they’re estrogen dominant. You can certainly see it in guys drinking a lot of beer, a lot of phytoestrogens. You will tend to see a combination of weight gain that is promoted by high phytoestrogen exposure.

And in females, you can see that too. There are certainly estrogen-like traits with increased adiposity, certainly hormone dysregulation, which can go from dysregulated cycles to heavy clotting to dysmenorrhea, amenorrhea.

It can go both ways. And there are, again, the mixing or muddying of the water tends to be conflated by the increased estradiol will suppress thyroid hormone, will suppress progesterone … I think keeping prolactin as low as possible is great. And … progesterone will do that. It is predominantly a female hormone, but men do need it as well.”

A Comprehensive Approach Works Best

Littlewood emphasizes that addressing your thyroid problems isn’t as simple as taking thyroid hormones. You need to use a comprehensive approach that addresses what you’re eating — avoiding low-carb and low-calorie diets — your stress levels and your exposure to environmental pollutants, like endocrine-disrupting chemicals.

“You can throw light deficiency with that as well, inadequate vitamin D,” Littlewood says. “All of these things contribute to it.” Often, it’s the most fundamental, simple changes that make the biggest difference in your health. To that end, Littlewood also recommends regular exercise and movement, especially walking, to address endocrine issues and take your health to the next level:

“Very simple strategies can lead to some amazing results, and some of these things just get wrapped up in medical diagnosis, overtreatment, overdiagnosis, and I think this is still a huge problem. And like the ideas that we talked about, what are some of the things that Ray [Peat said that] have stuck with me? It’s understanding that you don’t need to go through this kind of overdiagnosis and overcomplication.

… exercise, I think, is key … I don’t think he [Peat] placed exercise as high up there as he might’ve done. But again, he talked about living a life that had a lot of contentment to it and doing things that were useful and interesting, rather than spending a life of overexercising and breathless exercise, which would lead to this hyperthyroid state anyway.

… the right amount of exercise, it’s not too much, certainly not too little, and that’s, again, something you tend to see — people who’ve been exercising five, six days a week push themselves into a hole. So yeah, adequate strength training, mobility training, moderate amount of cardiovascular exercise through regular walking I think is where most people need to be.”

Your body runs on a roughly 24-hour internal clock called the circadian rhythm, and it governs far more than when you feel sleepy or wide awake — it may also affect when you’re most vulnerable to a stroke. For a lot of people, the riskiest stretch falls in the hours right after they get out of bed.

Researchers who investigated stroke incidents keep noticing the same pattern: Cases tend to bunch up in the morning rather than spreading evenly across the day. With strokes now one of the leading causes of death (more than 795,000 Americans have a stroke every year1) and disability in the U.S.,2 knowing this pattern can help sharpen how quickly you and the people around you catch the warning signs.

So what is it about the morning that seems to tip the scales toward a stroke? The trail leads to the daily swings in your blood pressure, changes in how easily your blood clots, and the internal timekeeping system that helps coordinate both.

Ischemic Strokes Cluster in the Morning, While Nighttime Strokes Tend To Be More Severe

A 2026 systematic review published in the International Journal of Cardiology Cardiovascular Risk and Prevention set out to map when strokes actually occur and whether the timing lines up with how severe they turn out to be.3 The researchers combed six databases including PubMed, Embase, and Scopus, starting with 1,010 records and eventually narrowing it down to 58 observational studies for analysis. Each study was graded for quality using the Newcastle-Ottawa Scale, a scoring tool for observational research.

The researchers looked at two types of stroke: ischemic stroke, which occurs when a clot or plaque blocks a vessel feeding the brain, and hemorrhagic stroke, caused when a vessel ruptures and bleeds; the review noted that ischemic strokes make up roughly 87% of cases.

• Ischemic strokes concentrated in the morning hours — Across the included studies, ischemic strokes tended to occur between 6:00 a.m. and noon, with some studies instead recording a bimodal pattern, meaning two peaks — one in the morning and a second in the evening.

To keep comparisons consistent, the reviewers grouped the day into four blocks: night (midnight to 5:59 a.m.), morning (6:00 to 11:59 a.m.), afternoon (noon to 5:59 p.m.), and evening (6:00 to 11:59 p.m.). The morning clustering showed up repeatedly across different research teams and countries, which is part of why the authors treated it as a reasonably well-supported trend rather than a one-off result.

• One large analysis put numbers on the morning spike — The review cited a meta-analysis of 11,816 stroke patients reporting that risk ran significantly higher during the 6:00 a.m.-to-noon window than across the remaining 18 hours of the day.

In that analysis (which will be discussed in detail in the next section), the risk of ischemic stroke was elevated by about 89%, hemorrhagic stroke by 52%, and transient ischemic attack (also known as a “mini-stroke”) by 80% during the morning hours. The overnight stretch from midnight to 6:00 a.m. showed the opposite: notably lower risk for every stroke type compared with the rest of the day.

• Hemorrhagic stroke timing was less consistent — The picture for bleeding strokes was mixed. Some studies found the highest incidence in the early morning, with one reporting that roughly 48% of intracerebral hemorrhage cases occurred between 6:00 a.m. and noon, while others pointed to a peak in the late evening or nighttime.

Subarachnoid hemorrhage, a bleed in the space around the brain, showed a morning peak in some reports plus a secondary evening peak in others. The authors were candid that this inconsistency likely reflects different underlying mechanisms and patient factors.

“Multiple studies demonstrated that the incidence of hemorrhagic stroke exhibits a circadian variation; however, this rhythmic pattern is not entirely consistent and may differ according to stroke subtype, patient-specific characteristics, and environmental influences,” they noted.4

• Strokes that began at night tended to be more severe — Beyond counting cases, the review examined outcomes and found that nocturnal and early-morning strokes were associated with more serious symptoms and poorer recovery. Patients with nighttime onset often arrived with higher scores on the National Institutes of Health Stroke Scale, a measure where higher numbers mean greater neurological impairment.

• The authors suggested this may owe partly to delays in treatment — A stroke that starts during sleep can go unwitnessed and unrecognized until hours later. They also noted that not every study agreed — one study, for example, found no significant difference in three-month mortality by time of onset. “Wang et al. reported no significant difference regarding three-month mortality rates or early reperfusion success among patients with strokes occurring at different times,” the researchers said.

• Daily swings in blood pressure and clotting offer a plausible explanation — For the morning pattern, the review pointed to normal circadian physiology. Blood pressure typically falls overnight and rises rapidly on waking, and that abrupt shift may destabilize blood flow in the brain.

The authors also cited evidence that platelet activity and clotting factors climb in the morning, which can raise the chance of a vessel-blocking clot. Because the included studies spanned varied populations and settings, the reviewers cautioned that these trends need further research to fully untangle.

An Earlier Analysis Found a Morning Spike Across Every Type of Stroke

The morning clustering seen in the broader review didn’t come out of nowhere — much of it traces back to an earlier landmark meta-analysis. Published in 1998 in Stroke (the journal of the American Heart Association), the research pulled together decades of scattered reports to ask a single question: Is there a time of day when strokes are more likely to begin?5

• The analysis pooled 31 studies covering 11,816 strokes — The author gathered published reports from around the world that recorded when stroke symptoms began, then sorted them by time of onset and, where possible, by stroke type. When a study didn’t give precise timing, those strokes were spread evenly across the day on purpose, a conservative choice that makes any real pattern harder to detect rather than easier.

In other words, the method was tilted against finding a morning spike, which makes the result that follows more convincing. The strokes were divided into standardized blocks such as midnight to 6 a.m., 6 a.m. to noon, noon to 6 p.m., and 6 p.m. to midnight.

• Strokes of all types spiked between 6 a.m. and noon — Across every way the data were sliced into three-, four-, or six-hour windows, a statistically significant morning pattern appeared. Compared with what you’d expect if strokes fell evenly across the day, there was a 49% increase in strokes of all types during the 6 a.m.-to-noon window, with a 95% confidence interval of 44% to 55%.

Measured against the normalized rate for the other 18 hours of the day, that same morning excess worked out to a 79% increase.

• The morning window ran higher for ischemic, hemorrhagic, and mini-strokes alike — When broken out by type, all three subtypes showed a significantly elevated morning risk. Ischemic strokes were 55% more likely between 6 a.m. and noon across 8,250 cases, while hemorrhagic strokes were 34% more likely in that window across 1,801 cases.

Meanwhile, transient ischemic attacks were 50% more likely across 405 cases. These per-type figures are the same analysis the 2026 review drew on when it reported the morning excess above.

• The quietest stretch was overnight, while the morning share was sizable — The six-hour block from midnight to 6 a.m. carried the lowest risk, with 29% fewer strokes than expected under an even distribution, or a 35% drop compared with the other 18 hours. Putting the excess in plain terms, the author estimated that roughly 1 in every 8 strokes is attributable to the morning surge, breaking down to about 1 in 7 ischemic strokes, 1 in 10 hemorrhagic strokes, and 1 in 8 transient ischemic attacks.

• These findings overturned an older assumption about sleep — For years, the prevailing view held that strokes mostly struck during sleep and therefore weren’t a medical emergency worth rushing to catch. This analysis contradicted that idea, indicating that regardless of stroke type, most patients are awake when symptoms begin. The author argued that recognizing new neurological deficits early warrants treating the event as an emergency, or a “brain attack.”.
• Daily blood pressure swings offer the leading explanation — The author pointed to blood pressure as one of the most powerful stroke risk factors, noting that its natural daily rhythm closely parallels the timing of stroke onset. Blood pressure and heart rate climb roughly 20% in the hours around waking, the same stretch tied to higher rates of stroke, heart attack, and sudden cardiac death.

The morning surge also lines up with daily patterns in physical activity and stress hormones such as cortisol and catecholamines.

Because the underlying reports were rarely population-based, could be subject to publication bias, and relied on patients or witnesses recalling when symptoms started, the conclusions come with real limits. The data weren’t adjusted for wake times or for people working night and evening shifts, so more research was needed to refine the picture.

How the Shift from Sleep to Waking Raises Stroke Risk

The two featured studies establish that strokes favor the morning; but to provide better understanding, it helps to know the many small biological shifts that stack up in those hours — when you transition from sleeping to waking — and how they raise your risk.

• The move from sleep to waking strains the heart and vessels — During sleep, blood pressure and heart rate drop, but when you wake up, both jump back up. That abrupt swing can stress blood vessels and raise stroke risk.

Heart rate variability, the natural variation in time between heartbeats and a rough gauge of how well the heart adapts to stress, tends to run higher at night and lower in the morning, with lower readings linked to greater stress and stroke risk. In addition, cortisol, a stress hormone that peaks in the morning, can push blood pressure up during the same window, compounding the effect.6

• Overnight dehydration may thicken the blood — Fluid balance is another morning factor that has been associated with stroke risk.7 Because you go for hours without drinking during sleep, the body’s fluid levels are lowest on waking, which can decrease blood volume and increase viscosity. Thicker, stickier blood is described as more prone to clotting,8 which ties overnight dehydration to the morning clot-formation pattern. Spreading fluid intake across the day may help keep the blood more fluid.

• Seasonal factors add to the morning load — Winter carries a higher stroke risk, especially in the mornings, because cold temperatures cause blood vessels to narrow, which can raise blood pressure. Large temperature swings could also be a stressor, since the body works harder to stay warm, adding strain to the heart and circulation.

• Timing patterns shift across age, gender, and ethnicity — In particular, older adults tend to have strokes in the morning, which is attributed partly to blood pressure changes and stiffer, less flexible blood vessels with age. Women may experience strokes at different times than men, possibly related to hormonal changes, although more research is needed on the gender difference.

African Americans also face a higher stroke risk than other groups, with different timing patterns, tied to a mix of genetic, lifestyle, and social factors.

• The time of day can shape how fast help arrives — Figures suggest hospital staffing and readiness vary by hour, with higher daytime staffing and faster average response, and lower staffing overnight with slower response. This may be one reason nighttime strokes can fare worse, since recognition and care may lag.9

BE FAST — The Warning Signs That Matter Most When a Stroke Strikes

A stroke happens when a clot or blockage keeps part of the brain from getting the blood it needs. Because a starved brain region simply stops working, the symptom of this condition is often something disappearing rather than a new pain or sensation. Loss of vision, speech, movement, sensation, or balance are key signs, especially when they show up on one side of the body.10 Hence, it pays off to be able to recognize these signs when they happen, so you can act fast.

• The “BE FAST” acronym packs the signs into six letters — A HuffPost article lays out a memory aid that turns stroke symptoms into something you can recall under pressure: BE FAST, which stands for:

◦ Balance — Sudden loss of coordination
◦ Eyes — Blurred vision or vision loss
◦ Face — Drooping on one side
◦ Arm — Weakening of the limbs
◦ Speech — Speech difficulty or slurring of words
◦ Time — Call 911 right away

As soon as any of these appear, contact emergency medical services and get help immediately.
• Sudden onset is what separates a stroke from a slower problem — Dr. Gregory Albers, a professor of neurosurgery and director of the Stanford Stroke Center in California, said that stroke symptoms come on instantly rather than building gradually over days. “So, if your arm has been getting weaker for days … that’s not a stroke. It’s your arm is fine, and then bam, all of a sudden it gets weak,” he explained.11

• Speed changes what treatment is even possible — The reason BE FAST hinges on that final “T” is that stroke care runs on a tight clock. Dr. Dileep Raghvendra Yavagal, a professor of clinical neurology and neurosurgery at the University of Miami Miller School of Medicine, noted that strokes are treatable.

Clot-busting medication can be given up to four-and-a-half hours after symptoms begin, he explained, and beyond that window a procedure called a thrombectomy can physically remove the clot to restore blood flow. The earlier a stroke patient seeks emergency assistance, the more treatment options are available.

Everyday Habits That Support a Lower Stroke Risk

Experts view stroke as a largely avoidable health condition — “In 2026, stroke is highly preventable,” Yavagal said.12 Following healthy lifestyle habits, including consuming a nutritious diet, doing regular physical activity, avoiding tobacco, getting adequate sleep, and keeping blood sugar and blood pressure in healthy ranges, is linked to a substantially lower risk of stroke. Below are some of my recommendations:

1. Move your body regularly — Exercise helps normalize your blood sugar and improve insulin and leptin receptor signaling, which in turn supports healthy blood pressure — a key piece of the stroke-risk picture.

In a 2013 study published in Stroke, walking at least three hours a week was associated with lower stroke risk in women, not only compared with being inactive but also compared with high-intensity cardio.13 If you’ve already had a stroke, staying active is linked to better physical and mental recovery and a lower chance of a repeat event.

2. Get the right amount of sleep — A 2020 study published in Neurology noted that regularly sleeping nine hours or more was associated with a 23% higher stroke risk, compared with sleeping seven to eight hours a night. Sleeping less than six hours showed no significant effect.14

Long midday naps of more than 90 minutes were also linked to a 25% higher risk than napping 30 minutes or less. People who both slept nine-plus hours and napped more than 90 minutes carried the highest risk, an 85% increase over moderate sleepers and nappers. Poor sleep cuts the other way too: a genetic predisposition to insomnia has been associated with higher rates of large-artery, small-vessel, and cardioembolic stroke.15

3. Eliminate “diet” soda and energy drinks — A 2017 study published in Stroke reported that regular consumption of artificially sweetened “diet” soda has been linked to a significantly higher 10-year stroke risk.16 Caffeine-loaded energy drinks are another concern, since they can make the blood stickier, which may contribute to clot formation.

Case reports have described cardiovascular events following heavy energy-drink consumption, though the size of any added risk is not well established. Reaching for water, mineral-rich whole fruit, or other real-food options in their place is a simple daily swap.

4. Build in stress relief into your routine — A 2008 study found that higher psychological distress tracked with greater stroke risk: For every notch lower a person scored on a well-being scale, their risk rose by about 11%, and the link was most pronounced for fatal strokes.17

Emotional Freedom Techniques (EFT) is a favorite tool for defusing stress in the moment, and prayer, meditation, laughter, and yoga are other approaches with strong track records. Finding one that fits your routine makes it easier to stick with.

5. Reconsider alcohol and tobacco — Heavy drinking in midlife has been flagged as a stroke risk factor — in one study, people averaging more than two drinks a day showed a 34% higher risk than those averaging less than half a drink.18 In one analysis of identical twins, heavy drinking shortened the time to stroke by roughly five years.

Meanwhile, smoking ranks among the major risk factors for stroke, so quitting is one of the highest-impact moves available if you’re working to bring your risk down.19

Frequently Asked Questions (FAQs) About Strokes

Q: What time of day are strokes most common?
A: Research consistently points to the morning, generally between 6 a.m. and noon, as the window when strokes are most likely to begin. A meta-analysis of 11,816 strokes found a significant morning increase across every stroke type, and a systematic review of 58 studies reported the same clustering for ischemic strokes, the clot-caused type. Strokes can still happen at any hour, but the early-morning stretch stands out in the data.

Q: Why are strokes more common in the morning?
A: Researchers attribute the pattern mainly to your body’s natural circadian rhythm. Blood pressure typically dips overnight and rises as you wake, and that abrupt swing can strain blood vessels. Studies also indicate that the blood tends to be “stickier” and more prone to clotting in the early hours, while the body’s clot-dissolving mechanisms work less effectively.

Q: How can I recognize the warning signs of a stroke?
A: Stroke specialists recommend the acronym BE FAST: B for balance loss, E for eye or vision changes, F for facial drooping, A for arm weakness, S for speech difficulty, and T for time to call 911. A key feature is that stroke symptoms come on suddenly rather than building gradually over days, often affecting one side of the body. Because the tell is usually something that abruptly stops working, quick recognition matters.

Q: Are strokes that happen at night more dangerous?
A: Some evidence suggests strokes that begin overnight are associated with greater severity and poorer recovery. Part of the reason appears to be delayed treatment, since a stroke that starts during sleep can go unwitnessed and unrecognized until hours later. Not every study agreed, though — at least one found no significant difference in three-month mortality by time of onset.

Q: Is stroke actually preventable?
A: Experts describe stroke as largely preventable, with one specialist estimating roughly an 80% chance of prevention through healthy lifestyle habits. Everyday factors linked to lower risk include regular physical activity, adequate sleep, stress management, moderating alcohol, and avoiding tobacco. Keeping blood pressure, blood sugar, and other markers in healthy ranges is also part of the picture.

Nutrient absorption
Liver enzyme activity

The human body is designed to thrive with the right conditions — proper nutrition, regular movement, and minimal toxin exposure. These factors create the foundation for optimal health, allowing every system to function as intended.

However, modern lifestyles are working against these basic needs, causing disruptions at the cellular level. The result is widespread chronic illness, dependency on prescription drugs, and a health care system that treats symptoms rather than addressing the underlying problem. Reducing these modern exposures and returning to habits that support cellular health is a practical starting point for many people.

Dietary Catastrophe Has Redefined What We Call Food

Walk into any grocery store, and you’ll see shelves lined with products that claim to be “healthy,” “natural,” or even “nutrient-packed.” Flip them over, and the ingredient lists tell a different story. These foods are filled with artificial flavors, preservatives, and cheap fillers that extend shelf-life and make them highly palatable and easy to overeat.1 What they lack, however, is real nutrition.

• Foods are stripped of essential nutrients during processing — When you consume a diet full of packaged snacks, sugary cereals, ready-made meals, and other processed options, you’re getting plenty of calories, but you’re missing out on important nutrients, including magnesium, B vitamins, vitamin E, omega-3s, and zinc.2 This can leave you undernourished in key micronutrients even when you are eating more than enough food.3

• Excess sugar is another major culprit in modern diets — Decades ago, sugar was a rare treat,4 but now it is hidden in almost everything, from salad dressings to yogurt to so-called “healthy” protein bars. This makes it easy to consume far more sugar than your body handles well — a pattern associated with weight gain, insulin resistance and, over time, Type 2 diabetes.5

• Seed oils are among the most problematic fats in the modern diet — Extracted under extreme heat and pressure from sources like soybean, canola, corn, safflower, and sunflower, highly processed industrial seed oils didn’t even exist in the human diet until the 20th century. Now, they make up a massive portion of daily fat intake.6

Sold as “vegetable oils” and marketed as healthy alternatives to traditional animal fats, seed oils are actually loaded with linoleic acid (LA), an omega-6 polyunsaturated fat (PUF) that is highly unstable and prone to oxidation.

• LA promotes inflammation at the cellular level — Unlike saturated fats, which remain chemically stable, LA undergoes lipid peroxidation, generating toxic byproducts called oxidative linoleic acid metabolites (OXLAMs). One example is 4-HNE (4-hydroxynonenal), a compound shown in laboratory research to damage DNA, proteins and mitochondria.7

• Excess LA accumulates in your fat tissue over time — Once inside your body, LA remains for years and can convert into metabolites that promote inflammation. Researchers have proposed that this contributes to mitochondrial dysfunction, which is being investigated as an underlying factor in metabolic conditions including obesity, diabetes, cardiovascular disease and neurodegenerative disorders.
Importantly, LA is an essential fatty acid and is required for normal mitochondrial function — the goal is not to eliminate it, but to keep your intake within 2 to 5 grams per day.

• Convenience has replaced real food preparation — Meals used to be prepared with fresh, whole ingredients, but now, convenience is king. Instead of real food, processed and fast food make up a majority of most people’s daily diet. This results in a slow but steady decline in health, leaving people unhealthier than ever before.

• Ultraprocessed foods are designed to keep you hooked — Food companies employ scientists to engineer the perfect mix of fat, sugar, and salt to trigger cravings and hijack your brain’s reward system in ways that real food never could.8 The more ultraprocessed food you eat, the harder it is to stop — your taste buds adapt, your metabolism adjusts, and cravings for those same foods intensify.

A Sedentary Lifestyle Is One of the Biggest Health Threats

The human body was built for movement, yet modern life has turned sedentary lifestyles into the norm. A 2024 survey found that one-third of Americans spend at least eight hours a day sitting, whether at a desk, in the car, or in front of a screen.9 Prolonged inactivity is associated with faster physical decline, and pooled observational data have linked the highest sitting levels to roughly a 30% higher risk of premature death. Notably, this association persists even among people who exercise regularly.10

• Prolonged sitting disrupts blood sugar regulation — Sitting for long periods reduces muscle activity, which makes glucose uptake less efficient — a pattern associated with insulin resistance and, over time, Type 2 diabetes.11 In observational research, adults who sat more than eight hours a day had about a 17% higher relative risk of developing diabetes than those who moved regularly.12

• Inactivity takes a toll on your heart — Inactivity is associated with stiffer blood vessels, slower circulation and greater arterial plaque buildup.13 Observational studies report higher rates of heart disease among adults who sit for most of the day, even when they exercise occasionally.14

• A sedentary lifestyle promotes fat storage — Physical inactivity shifts your metabolism in ways that favor fat storage.15 In observational research, physically inactive adults had about a 52% higher relative risk of obesity than more active individuals.16 This process creates a vicious cycle where inactivity causes weight gain, and excess weight makes movement even harder, leading to even more health complications.

• Your brain suffers from inactivity, too — Exercise stimulates the release of brain-derived neurotrophic factor (BDNF), a protein essential for cognitive function and mental clarity. Lower BDNF levels have been associated with declines in memory, focus, and mood.17 Studies have linked sedentary lifestyles to an approximately 40% higher risk of depressive symptoms18 and a 30% higher risk of developing neurodegenerative diseases like Alzheimer’s.19

• Inactivity triggers emotional and mental stagnation — People who don’t move enough often feel foggy, unmotivated, and even anxious, as physical movement is essential for proper brain function and emotional regulation.

• Children are affected just as much, if not more — Where past generations spent their childhood climbing trees, riding bikes, and running around for hours, today’s youth spend an average of 7.5 hours per day in front of screens.20 This shift has paralleled rising childhood obesity rates, reduced muscular fitness and greater long-term chronic disease risk.21

• Early inactivity has long-term consequences — Approximately 19.7% of U.S. youths are classified as obese, affecting 14.7 million children and adolescents aged 2 to 19 years.22 The habits formed in childhood don’t just disappear in adulthood — they shape long-term health outcomes in ways that are difficult to undo.

The Toxins Hiding in Your Everyday Environment

Every day, you are exposed to various environmental toxins, some of which didn’t even exist a century ago. Industrial pollutants, plastics, pesticides, and synthetic additives have infiltrated the food you eat, the air you breathe, and the water you drink. Many of these substances interfere with your body’s natural functions, and the longer you wait to address these exposures, the more damage they do.

• Endocrine disruptors interfere with hormone activity — Endocrine disruptors (EDCs) are one of the most insidious culprits in your environment. Your endocrine system regulates everything from metabolism to reproduction, and even small disruptions have considerable consequences.23 EDCs mimic, block, or alter hormone activity. Research has associated EDC exposure with infertility, thyroid disorders, metabolic dysfunction, and hormone-related cancers.24

• Plastics are a major source of EDC exposure — Water bottles, food containers and plastic wraps leach harmful chemicals like bisphenol A (BPA) and phthalates into food and beverages. Many of these compounds act as xenoestrogens, meaning they mimic estrogen and disrupt hormonal balance.

• Plastic exposure affects men and women differently — For men, this means lower testosterone, reduced muscle mass, and increased fat storage.25 For women, exposure has been associated with irregular menstrual cycles, fertility problems and higher rates of estrogen-driven cancers.26 Research has shown that more than 90% of Americans have detectable levels of BPA in their urine,27 an indication of how widespread plastic exposure has become.

• VOCs pollute indoor environments — Some volatile organic compounds (VOCs) also act as EDCs.28 VOCs are a group of chemicals that easily evaporate into the air. They’re emitted from air fresheners, cleaning chemicals and disinfectants, and even furniture.29 Indoor air is often two to five times more polluted than outdoor air,30 meaning that without proper ventilation, you are inhaling a constant stream of airborne toxins inside your own home.

• VOCs trigger serious health effects — VOC exposure has been linked to respiratory problems, fatigue, headaches, and nervous system effects. Some VOCs, like benzene and formaldehyde, are also classified as carcinogens. Long-term exposure has been linked to liver and kidney damage, immune suppression, and hormone disruption.31,32

• Water contamination is a hidden danger — Water contamination is another major issue as it exposes you to a cocktail of harmful chemicals in the very water you drink. Municipal water supplies can contain chlorine, fluoride, heavy metals, and pesticide runoff, and some of these — heavy metals in particular — accumulate in your body over time.33

Chlorine affects your gut bacteria,34 fluoride has been linked to altered thyroid function35 and heavy metals like lead, arsenic, and mercury are established neurotoxins.36 If your tap water is fluoridated, a high-quality filtration system designed to remove fluoride is the practical fix (Be aware that common pitcher filters such as Brita or PUR will not remove it).

• Pharmaceutical residues contaminate drinking water — Antibiotics, birth control hormones, antidepressants, and blood pressure medications persist in drinking water and contribute to endocrine disruption, antibiotic resistance, reproductive issues, and developmental problems.37

Even bottled water isn’t necessarily safer, as many brands test positive for microplastics38 and the industry is regulated less stringently than public tap water — the U.S. Food and Drug Administration (FDA) lacks authority to require bottlers to use certified testing labs or report their results, both of which the Environmental Protection Agency (EPA) requires of municipal systems.39

Electromagnetic Fields — An Invisible Modern-Day Threat

Another hidden but serious threat to cellular health is electromagnetic field (EMF) exposure. Unlike chemical toxins, which are ingested or inhaled, EMFs are invisible, surrounding you every day through cellphones, Wi-Fi routers, smart meters and other wireless technology. Because they permeate the environment, they are nearly impossible to avoid, making them one of the most overlooked dangers to human health.

• Modern EMFs operate at biologically disruptive frequencies — EMFs cover a broad spectrum, including natural sources like sunlight, which play essential roles in biological function. However, modern high-frequency EMFs, emitted by cellphones, Wi-Fi and 5G networks, operate in the gigahertz range, and researchers have raised concerns that they disrupt cellular processes in ways current safety standards do not fully account for.

• Nonthermal EMFs disrupt cellular signaling — Unlike ionizing radiation, such as X-rays, which directly break DNA, EMFs cause harm through nonthermal effects, meaning they disrupt cells without raising tissue temperature. This makes the effects harder to detect, which is part of why they remain contested.

Research indicates EMFs can alter cellular signaling and activate voltage-gated calcium channels, which may in turn affect mitochondrial function and contribute to oxidative stress and DNA damage.

• EMFs trigger mitochondrial breakdown through calcium flooding — One of the most concerning effects is how EMFs flood cells with excess calcium ions, which triggers a chain reaction that fuels oxidative stress and mitochondrial failure.

This process mirrors the damage caused by seed oils and EDCs. Researchers have proposed that this contributes to chronic inflammation and reduced cellular energy, and have called for further investigation into links with neurodegenerative disease, infertility, and cancer.

• Telecom industries have downplayed these dangers for decades — In 1996, the Telecommunications Act was passed. Section 704 prevents state and local governments from blocking wireless facilities on the basis of RF emissions that comply with FCC limits — a provision critics say has insulated the industry from health-based challenges.40 Industry-funded research have since drawn sustained criticism from independent researchers.41

• The “no heat, no harm” myth is false — The narrative that “if it doesn’t burn you, it’s safe” is deeply misleading. Dr. Martin Pall, Emeritus Professor of Biochemistry and Basic Medical Sciences at Washington State University, has argued that existing safety standards for non-ionizing EMFs substantially understate biological effects.42

• Chronic exposure leads to cumulative damage — While EMFs don’t cause immediate thermal damage, the long-term, cumulative effects of exposure warrant closer attention. The World Health Organization’s cancer agency classifies radiofrequency electromagnetic fields as possibly carcinogenic to humans, based on an observed increase in glioma risk associated with wireless phone use.43 Because any effects develop gradually, they are easy to overlook.

The Impact of Stress and the Mental Health Crisis

Modern life has introduced an overwhelming number of stressors to the human body, such as work deadlines, financial strain, digital overload and the constant pressure to perform. Unlike short bursts of stress, which help you react to danger, chronic stress keeps your body in a permanent state of emergency, disrupting nearly every system.

• Chronic stress keeps cortisol dangerously elevated — The human body isn’t designed to handle this amount of relentless assault, and the damage is showing. When stress becomes chronic, cortisol — the body’s primary stress hormone — remains elevated for long periods. Sustained cortisol elevation is associated with increased inflammation and reduced immune function.44

• Stress significantly raises the risk of major diseases — Observational studies have associated chronic stress with a 40% to 60% higher relative risk of cardiovascular disease45 and with increased risk of Type 2 diabetes.46 In one cohort study, people reporting high stress were about 33% more likely to experience a stroke.47

• High cortisol levels disrupt sleep and brain recovery — When your brain is flooded with stress hormones, your brain also struggles to wind down. This is why insomnia and restless sleep are common in people with high-stress lifestyles.48

• Sleep deprivation worsens metabolic and hormonal function — Sleep deprivation is associated with impaired metabolic function,49 reduced memory performance,50 higher obesity risk, and lower insulin sensitivity.51 It also increases ghrelin (which makes you feel hungry) and reduces leptin (which signals fullness), leading to overeating and food cravings.52

• The mental toll of chronic stress is just as destructive — Anxiety disorders affect more than 40 million adults in the U.S.,53 making them the most common mental health issue today. Depression is a leading cause of disability among working-age Americans,54 and chronic stress is a well-documented contributing factor.

• Stress physically rewires your brain for fear and dysfunction — When your brain is exposed to prolonged stress, it rewires itself for fear, overreaction and negativity. This makes it harder for you to regulate emotions and focus. Prolonged stress has also been associated with reduced hippocampal volume — the brain region central to memory and learning55 — along with brain fog, difficulty concentrating and, in some longitudinal research, higher rates of Alzheimer’s disease.56

• Chronic stress shortens lifespan — Chronic stress has been associated with markers of cellular aging,57 including shorter telomere length — the protective caps on DNA that play a significant role in longevity.58

• The stress cycle becomes self-perpetuating — The more stress you endure, the harder it becomes to escape its grip. Left unaddressed, chronic stress affects far more than mood — it influences your biology in ways associated with poorer long-term health.

A Wakeup Call

Despite medical advancements and a health care system that spends trillions each year, Americans are getting sicker. Poor diet, environmental toxins, sedentary lifestyles, and chronic stress are each associated with metabolic dysfunction and reduced cellular energy production — together creating conditions in which chronic disease becomes more likely.

• Conventional medicine focuses on symptoms, not root causes — Instead of targeting the root causes of this modern health crisis, conventional medicine remains fixated on symptom management. Medications often manage symptoms without addressing what drives them. Both approaches have a place — but without more attention to underlying causes, the burden of chronic disease is likely to keep growing.

• The good news is, chronic ill health is not unavoidable — Many chronic conditions are strongly influenced by modifiable factors, and research suggests meaningful improvement is possible for many people. Your body is not failing — it is responding to an environment that makes optimal cellular function harder to sustain.

• True healing requires a shift in focus — A growing body of research points to cellular and mitochondrial function as an underexplored factor in chronic disease — one that short-term interventions alone are unlikely to address. The future of medicine will likely need to look beyond symptom control to where health begins: at the cellular level.

The encouraging part is how much of this sits within your control. Eating real food, getting sunlight, walking an hour a day, filtering your water, reducing plastic use, and putting your phone down at night are ordinary changes with real physiological effects. None of it requires perfection — small, consistent choices compound, and the body is remarkably responsive when conditions improve.

Frequently Asked Questions (FAQs) About the Modern Drivers of Chronic Disease

Q: What are the factors behind today’s chronic disease epidemic?

A: Modern lifestyles disrupt cellular health through poor nutrition, lack of movement, environmental toxins, and chronic stress. These conditions are associated with impaired mitochondrial function, reduced energy production, and increased inflammation — factors researchers link to chronic illness.

Q: Why is the modern food supply damaging to health?

A: Today’s processed foods are stripped of essential nutrients and loaded with sugar, synthetic additives, and seed oils high in linoleic acid. These ingredients are associated with disrupted metabolism, increased inflammation, and higher rates of obesity, insulin resistance, and other metabolic disorders.

Q: What role does chronic stress play in long-term illness?

A: Chronic stress keeps cortisol levels elevated, which triggers inflammation, weakens the immune system, and disrupts sleep and metabolism. Over time, this pattern has been associated with changes in brain structure, accelerated cellular aging and higher risk of cardiovascular disease, diabetes, and neurodegeneration.

Q: How do everyday toxins contribute to disease?

A: Plastics, endocrine disruptors, VOCs, and contaminated water interfere with hormone function, damage mitochondria, and accumulate in tissues. These exposures are constant and, in some cases, cumulative, and researchers are investigating their combined contribution to chronic dysfunction.

Q: Are EMFs actually harmful?

A: Research indicates EMFs from wireless devices, Wi-Fi, and 5G networks can affect calcium signaling, mitochondrial function and oxidative stress. Any effects are not immediate, which is part of why they remain debated — but they warrant attention.

When a morning bowel movement doesn’t happen on schedule, the usual suspect is yesterday’s dinner. More often, the real culprit is what happened after dinner — specifically, how you slept and when. Your digestive tract doesn’t simply respond to what you eat. It also responds to how well you sleep and, just as importantly, when you sleep.

That connection gets overlooked because conventional advice almost always focuses on fiber, water and exercise. Those recommendations matter, but they leave out a factor that influences your digestion from the moment you close your eyes until the moment your feet hit the floor. Your evening routine, your bedtime consistency and even how much time you allow yourself after waking up all play a role in whether your body cooperates the next morning.

Rather than relying on coffee or hoping for better luck tomorrow, you have far more control over your morning than you might realize. The research below explains exactly how your sleep schedule shapes your digestive rhythm and what you can do each evening to support a better morning.

Your Digestive System Follows a Built-In Daily Schedule

A review published in Current Treatment Options in Gastroenterology examined how sleep affects the digestive system in both healthy people and those with disorders of gut-brain interaction.1 The researchers evaluated evidence covering normal digestive function, sleep disorders and conditions such as irritable bowel syndrome (IBS), while also reviewing available treatments that target sleep.

Their goal was to determine whether poor sleep makes digestive symptoms worse, whether digestive problems disrupt sleep or whether both influence each other. The researchers concluded that sleep deserves much more attention in digestive care, noting, “Sleep, a cornerstone of lifestyle management, appears to be the forgotten factor.”

• Your digestive tract intentionally slows down overnight before becoming active again — Every part of your digestive system follows a predictable daily rhythm. According to the review, saliva production falls by about 50% overnight, stomach emptying slows during the evening, and the waves of muscle contractions that move food through your intestines become much less active while you’re asleep.

Even the muscles of your colon reduce their normal activity during the night. These changes don’t mean digestion has stopped. Your digestive system is following a programmed rest period, slowing down overnight so it can ramp back up when you wake.

• Your gut and brain communicate constantly through hormones, nerves and gut bacteria — The review explained that your digestive tract actually contains up to 400 times more melatonin than your pineal gland in the brain. Inside your intestines, melatonin helps regulate gut movement and supports healthy gut bacteria.

At the same time, sleep deprivation activates your body’s main stress response system, called the hypothalamic-pituitary-adrenal (HPA) axis, increasing stress hormones that weaken the intestinal barrier and interfere with normal gut-brain communication. The researchers also found that your gut bacteria follow their own daily rhythm, so irregular sleep disrupts the balance of microbes that help digestion stay on track.

• Poor sleep predicted worse digestive symptoms better than digestive symptoms predicted poor sleep — People with IBS experienced sleep disturbances far more often than healthy adults, with a pooled prevalence of 37.6%. Many participants actually logged more hours of sleep than healthy individuals but still woke up feeling unrested; their sleep was fragmented by more frequent awakenings and spent disproportionately in lighter stages.

Those repeated awakenings were associated with greater abdominal pain, more digestive distress and lower quality of life. Researchers also found that insomnia predicted worse abdominal pain, anxiety and fatigue the following day, while digestive symptoms didn’t consistently predict the following night’s sleep quality.

• Disrupted body clocks increased digestive problems in everyday life — The review highlighted several real-world examples showing what happens when your internal clock falls out of sync. Waking up naturally increases colon contractions that move stool toward the rectum, preparing your body for a morning bowel movement. When sleep schedules constantly change, that timing becomes less predictable.

Researchers also reported that IBS occurred 81% more often among shift workers than among people with regular daytime schedules. Shift work often brings irregular eating habits and greater intake of processed foods, creating multiple pressures on normal digestive function at the same time.

• Sleep-focused treatments improved digestive health alongside better sleep — Because sleep influences so many parts of digestion, the researchers also reviewed therapies that target sleep rather than bowel symptoms alone. They found sufficient evidence that melatonin reduced overall IBS symptom severity while improving quality of life.

Cognitive behavioral therapy for insomnia also improved insomnia severity, sleep efficiency and overall sleep quality, with one study showing improvements in both sleep and digestive symptoms among college students with IBS and insomnia.

Based on the evidence reviewed, the researchers concluded that improving sleep deserves a much larger role in first-line digestive care alongside diet, exercise and stress management because healthy digestion depends on healthy sleep from the very beginning.

The research makes a convincing case that sleep shapes digestion at every level — hormones, gut bacteria, colon contractions, even the strength of your intestinal lining. The practical question is what that means for your evening routine and your morning.

Your Evening Routine Determines How Easily You Poop the Next Morning

As noted in a news feature published by EatingWell, a consistent bedtime teaches your digestive system when it’s time to go.2 Gastroenterologist Dr. Catherine Ngo explains that “consistent, high-quality sleep helps the digestive system maintain predictable patterns of motility, which supports regular bowel habits.” Instead of wondering whether your body will cooperate each morning, keeping a regular bedtime teaches your digestive tract when to rest and when to prepare for elimination.

Ngo also explains that going to bed and waking up at roughly the same time each day creates predictability and safety for your nervous system. Because your digestive tract responds to signals from both your brain and your gut, that steady schedule helps your colon anticipate periods of activity and rest, making it easier to move stool forward before you even head to the bathroom.

• Late nights disrupt the hormones that help keep digestion on schedule — Gastroenterologist Dr. Rucha Shah explains that staying awake far later than normal throws off the timing of cortisol, your body’s primary stress hormone.3 As she puts it, “When people are staying up really late, those cortisol levels are spiking at times that they’re not normally used to … and so then it creates this pattern where digestion gets thrown off.”

Shah adds that this problem often appears in people who work overnight shifts because their internal body clock rarely follows a regular daily rhythm. When your sleep schedule constantly changes, your digestive system loses the consistency it depends on.

• Human research linked poor sleep to measurable changes in the gut microbiome — A 2026 systematic review analyzed 41 human studies published between 2016 and 2025 that examined how sleep duration, sleep quality, insomnia and disrupted body clocks affect the gut microbiome — the community of bacteria and other microbes living in your digestive tract.4

Researchers found that poor sleep and circadian disruption were associated with changes in both the types of gut bacteria present and the beneficial substances they produce, including short-chain fatty acids, vitamins, hormones, neurotransmitters and bile acids that help regulate digestion, metabolism and immune function.

While the findings varied between studies because of differences in diet, age, health and research methods, the review concluded that improving sleep and circadian rhythms supports a healthier gut microbiome, giving you another reason to treat a consistent bedtime as part of your digestive health routine instead of simply a way to feel more rested.

• Rushing through your morning trains your body to ignore its own signals — The experts point out that many people accidentally work against their body’s natural urge to have a bowel movement simply because they’re trying to get out the door quickly. Ngo explains that “if rushed in the morning, you don’t have the time to relax and let the bowels evacuate.”5

Shah adds that successful bowel movements require the muscles around the rectum to relax. If you repeatedly suppress the urge because you’re short on time, your body gradually becomes less responsive to those natural signals, making regular bowel movements more difficult over time.

• A simple change in body position helps stool pass more easily — One practical recommendation involves placing a small stool beneath your feet while sitting on the toilet. According to Shah, raising your knees above your hips helps open the muscles involved in bowel movements, making it “exponentially easier to poop.”

It’s a straightforward mechanical adjustment that changes the angle of your lower bowel, helping stool move through more comfortably without medication, supplements or expensive equipment.

Make Your Evening Routine Work for Your Gut

If your mornings rarely go as planned, don’t focus only on breakfast or coffee. Start the night before. Your digestive system follows a daily rhythm, and the habits you repeat every evening shape what happens the next morning. Try making a few simple changes and sticking with them long enough for your body to recognize the pattern. Consistency matters far more than perfection.

1. Keep the same bedtime every day — Your digestive tract performs best when your sleep schedule stays predictable. Go to bed and wake up at roughly the same time every day, including weekends. That steady routine helps your body recognize when it’s time to rest and when it’s time to prepare for a morning bowel movement. If you stay up late several nights in a row, don’t expect your digestive system to stay perfectly regular. Your body responds best to repetition.

2. Give yourself enough time after you wake up — If you usually race through your morning, build in an extra 15 to 30 minutes. Your digestive system works better when you aren’t under pressure. Don’t ignore the urge to have a bowel movement because you’re running late. Repeatedly holding it trains your body to become less responsive over time, making constipation more likely.

If you often feel rushed, shifting your bedtime earlier is one of the simplest ways to create more time the next morning.

3. Support digestion after dinner instead of collapsing on the couch — Finish eating at least three hours before bedtime whenever possible so your digestive system has time to process your meal before you fall asleep. A light walk after your evening meal helps keep food moving through your digestive tract.

Even 10 to 20 minutes is enough to encourage normal stomach emptying and healthy intestinal movement. Pair that habit with steady hydration throughout the day instead of drinking large amounts of water right before bed, which interrupts sleep with nighttime bathroom trips.

4. Use better bathroom mechanics — Your body was designed to empty your bowels in more of a squat than a seated position. Place a small footstool under your feet so your knees sit higher than your hips while you’re on the toilet. That simple adjustment straightens the lower part of your bowel and allows the muscles involved in a bowel movement to relax more completely. If you haven’t tried it, you’ll often notice the difference immediately.

5. Build regularity through daily habits instead of quick fixes — Your digestive system responds to patterns, not shortcuts. Protect your sleep as carefully as you protect your diet. If your gut tolerates it well, gradually increase fiber-rich whole foods and stay physically active every day, but recognize that without consistent sleep, those habits lose some of their power.

I also encourage you to keep a simple journal for two weeks that tracks your bedtime, wake time and bowel habits. You’ll often spot patterns that weren’t obvious before, making it much easier to identify the routines that keep your digestive system working on schedule.

FAQs About Sleep and Bowel Movements

Q: Does poor sleep really affect my bowel movements?
A: Yes. Your digestive system follows a daily rhythm that depends on consistent sleep. Irregular bedtimes, poor-quality sleep and disrupted body clocks interfere with the normal patterns that move stool through your colon, making it harder for your body to stay regular.

Q: Why are morning bowel movements more common than bowel movements later in the day?
A: Your colon naturally becomes more active after you wake up, helping move stool toward the rectum. A regular sleep schedule reinforces this built-in timing, while inconsistent bedtimes make the process less predictable and increase the likelihood of constipation or delayed bowel movements.

Q: What nighttime habits help promote a morning bowel movement?
A: Going to bed at the same time each night, finishing your last meal at least three hours before bedtime, taking a 10- to 20-minute walk after dinner and staying well hydrated throughout the day all help support your digestive system’s natural rhythm. These simple habits work together to encourage more regular bowel movements.

Q: Why does rushing in the morning make it harder to poop?
A: Your body needs time to respond to its natural urge to have a bowel movement. If you repeatedly ignore that urge because you’re in a hurry, your body gradually becomes less responsive to those signals. Giving yourself an extra 15 to 30 minutes each morning makes it easier for your bowels to empty completely.

Q: Is there a simple way to make bowel movements easier without medication?
A: Yes. Placing a small footstool under your feet while sitting on the toilet raises your knees above your hips, creating a more natural squatting position. This helps relax the muscles involved in bowel movements and allows stool to pass more comfortably, especially when combined with healthy sleep habits and a consistent daily routine.

What can cause tonsil stones to keep coming back?

Bacteria and debris collecting in tonsil folds
Bacteria, food particles, mucus, and dead cells can collect in the folds of the tonsils, allowing stones to form again. Learn more.
Drinking too much water, causing debris to become stuck
Eating crunchy fruits and vegetables
Breathing only through the nose

Tonsil stones, also called tonsilloliths, are small, hardened deposits that form inside the natural folds of your tonsils.1 Most people who develop them share the same frustrating experience; they remove the stone, feel relieved and then discover another one weeks or months later. In the meantime, the stones often produce persistent bad breath that no amount of brushing seems to fix, adding a social burden on top of the physical discomfort.

The cycle continues because removal alone does nothing to change the environment that produced the stone in the first place. That pattern points to a deeper issue worth understanding. Your tonsils aren’t passive tissue — they actively filter bacteria and debris entering through your mouth and nose. But when the conditions inside your mouth shift in the wrong direction, that filtering system becomes overwhelmed.

Instead of clearing material away, your tonsils begin trapping it, and that trapped material is exactly what hardens into a stone.2 If you have dealt with recurring tonsil stones, the path forward isn’t a better removal technique. It starts with identifying the everyday habits and oral conditions that keep inviting them back, then making targeted changes that interrupt the cycle before the next stone has a chance to form.

The Conditions That Allow Tonsil Stones to Return

As noted in an educational article from Pure Holistic Dental, it’s not only important to remove visible tonsil stones but to understand why they develop in the first place.3 Tonsil stones are a sign that bacteria, food particles, mucus and dead cells continue to collect inside the tonsils instead of clearing away normally. Rather than treating them as an isolated problem, identify the habits and conditions that allow the buildup to continue so you reduce the chance that new stones develop.

Your tonsils serve as part of your immune system by filtering bacteria and other unwanted material entering through your mouth and nose. According to the authors, “The tonsils are the first line of defense for the immune system.”4 As this filtering system becomes overloaded, debris accumulates inside the tonsil crypts, the natural pockets and folds within the tonsils, where it gradually hardens into stones.

• Several everyday habits increase your risk of recurring tonsil stones — This includes poor oral hygiene, mouth breathing, chronic tonsillitis, enlarged tonsils, deep tonsil crypts, hormonal changes and an imbalance in the oral microbiome, the community of bacteria that naturally lives inside your mouth. Some of these factors are outside your control. For example, genetics determine the size of your tonsils and how deep the natural folds become.

Others are habits that you have the ability to improve. Every time food debris remains in your mouth, saliva decreases because of mouth breathing, or bacteria accumulate around your teeth and tongue, more material becomes available to collect inside the tonsils.

• Bacterial biofilms help explain why debris stays trapped instead of washing away — Biofilm is a thin, sticky layer created by bacteria that allows them to cling tightly to surfaces instead of being easily rinsed away. Dental plaque is one familiar example of a biofilm.

Bacteria thrive inside the tonsil crypts. As these bacterial communities grow, they trap food particles, mucus and dead cells together, creating what the authors compare to “large, clogged pores.”

That sticky environment makes it much easier for material to remain lodged long enough to harden into a tonsil stone. Simply removing an existing stone does not remove the sticky bacterial community that helped create it. Improving daily oral hygiene helps reduce that bacterial buildup before another stone has a chance to form.

• Dry mouth and sinus problems allow bacteria to multiply more easily — Saliva does much more than keep your mouth comfortable. Saliva constantly rinses away bacteria and food debris while helping maintain a healthier balance of microorganisms inside your mouth.

Mouth breathing reduces that natural cleansing process because the tissues dry out more quickly. Certain medications also contribute by causing dry mouth, meaning your mouth doesn’t produce enough saliva. In addition, ongoing sinus drainage supplies extra mucus and bacteria that collect around the tonsils, adding even more material that becomes trapped inside the crypts.

If you often wake with a dry mouth, breathe through your mouth while sleeping or deal with frequent sinus congestion, those issues deserve attention because they create conditions that favor repeated stone formation rather than simply causing temporary discomfort. Once you understand the conditions driving the cycle, the next step is a daily routine that targets each one directly.

Simple Home Remedies Help Remove Small Tonsil Stones Safely

According to a Healthgrades article, many tonsil stones respond to simple self-care techniques that loosen trapped material without damaging the surrounding tissue.5 Small stones often respond well to conservative approaches performed carefully at home, while larger stones or persistent symptoms deserve medical attention.

This gives you a clear action plan. Instead of reaching for sharp tools or trying aggressive techniques, you can begin with the least invasive methods and move to professional care only if those steps fail.

• Salt water remains one of the simplest and most commonly recommended first steps — Try dissolving 1 teaspoon of table salt in 8 ounces of warm water and gargling for several seconds before spitting the solution out. Repeating this several times a day helps loosen small stones and also supports prevention by flushing debris from around the tonsils.

The benefit is mechanical as much as medicinal. Gargling creates movement that helps free trapped material while the warm salt water washes away bacteria and mucus from areas that are difficult to reach with a toothbrush. If you’re unsure where to start, make this your first challenge. Spend a few minutes each day gargling consistently before trying more direct removal methods.

• Gentle techniques reduce the risk of injuring delicate tissue — If gargling doesn’t remove the stone, try using the soft end of a cotton swab to carefully nudge stones that are easy to see and reach. Stand in front of a mirror in a well-lit room where you won’t be bumped unexpectedly. That reduces the chance of accidentally pushing too hard or scratching the tonsil tissue.

The goal is patience rather than force. If a stone doesn’t move with gentle pressure, stop instead of repeatedly poking at it. Protecting the surrounding tissue is more important than removing the stone immediately.

• Natural body responses often loosen stones without direct contact — Coughing sometimes dislodges tonsil stones on its own. Many people discover a stone after a hard coughing spell without realizing it had been trapped inside the tonsil beforehand.

Another option is a water irrigator. A gentle stream of water directed toward the tonsils helps wash away trapped debris while also encouraging coughing that finishes the job. Healthgrades stresses that an irrigator supplements brushing and flossing rather than replacing either habit. Think of these methods as working with your body’s normal cleaning systems instead of against them. Gentle rinsing and coughing place much less stress on your throat than aggressive scraping.

• A few simple foods support your mouth’s natural defenses — One recommendation that stands out in the article involves eating crunchy carrots or apples. Apples contain natural acids that may help fight bacteria, while carrots stimulate saliva production. Saliva constantly rinses your mouth, carrying away loose food particles and bacteria before they settle into hard-to-clean areas.

While these foods aren’t proven medical treatments, increasing saliva production supports a cleaner oral environment throughout the day. Consider adding one crunchy fruit or vegetable after meals as part of your daily routine. It’s a simple habit that works alongside brushing, flossing and other preventive measures instead of replacing them.

• Knowing when to stop home treatment protects your health — Home remedies are typically appropriate only for small stones that aren’t causing severe symptoms. If the stones continue returning, become difficult to remove, interfere with swallowing, or create persistent throat irritation, contact your primary care physician, who may refer you to an ear, nose and throat specialist.

One easy way to judge your progress is to ask yourself two questions each week: “Are the stones becoming less frequent?” and “Are my symptoms improving?” If the answer remains no despite careful home care, professional evaluation becomes the next logical step.

How to Keep Your Tonsils Clean Every Day

The remedies above address stones that have already formed. The next step is building daily habits that change the conditions inside your mouth so fewer stones develop in the first place. Earlier sections explained why bacteria, dry mouth and chronic drainage create the right environment for tonsil stones. The practical strategies below target each of those conditions directly, turning what you now understand about the problem into a routine you can follow every day.

1. Build a daily routine that removes bacteria before they collect — Brush your teeth twice a day, floss every day, and clean your tongue. If you skip even one of these habits regularly, bacteria have more places to grow. Think of these habits as a daily sequence rather than a checklist of equal parts. Brushing twice a day and flossing form the foundation. Cleaning your tongue targets the bacterial reservoir closest to your tonsils.

Rinsing your mouth after meals catches loose debris before it has a chance to migrate. When you run through that sequence consistently, each step reinforces the others, and the environment inside your mouth becomes far less hospitable to the buildup that leads to stones.

2. Keep your mouth moist and support a healthier oral microbiome — If you wake with a dry mouth or notice that you breathe through your mouth while sleeping, make nasal breathing one of your goals. Saliva constantly rinses away bacteria and loose particles, so keeping your mouth moist helps reduce buildup. Avoid alcohol-based or harsh antibacterial mouthwashes that disrupt the beneficial microbes living in your mouth.

Instead, try oil pulling with coconut oil. Use about 1 tablespoon for adults or 1 teaspoon for children. Gently swish the oil around your mouth and between your teeth for up to 20 minutes, then spit it into the trash and rinse with warm water. If you’re new to oil pulling, begin with one or two minutes and gradually increase the time.

3. Choose foods and rinses that help keep your mouth cleaner — Your diet influences the environment inside your mouth. Reduce heavily processed foods and foods loaded with refined sugar that encourage bacterial growth. Add crunchy foods such as apples or carrots after meals to stimulate saliva production, and drink enough water throughout the day so your mouth stays naturally clean.

If your throat feels irritated or you notice a small stone beginning to form, gargle with warm salt water or a mixture of about one-third cup of apple cider vinegar diluted in warm water to help loosen trapped debris.

4. Use gentle home removal methods instead of aggressive tools — If a tonsil stone is easy to see, begin with gargling. If it remains, try coughing deeply before attempting anything else. Sometimes that simple action is enough to dislodge the stone naturally. If necessary, gently ease it forward with a cotton swab, taking care not to push it deeper into the tonsil or back toward your throat.

If you’re helping a child, use extra caution because a loose stone could become a choking hazard. Never use sharp objects such as toothpicks or other pointed instruments because they can puncture the delicate tissue in your throat and cause bleeding. Remember that many tonsil stones loosen and fall out on their own without any intervention.

5. Think beyond the stone and improve your long-term oral health — Every stone you remove is a signal — your mouth is telling you the conditions that created it are still in place. Keep regular dental cleanings with a biological dentist on your schedule, especially if you have a history of recurring tonsil stones or chronic bad breath.

If you’re able to work with a biological dentist, ask about ways to support your oral microbiome and identify habits that contribute to recurring buildup. The more consistently you improve the environment inside your mouth, the less opportunity bacteria and debris have to collect inside your tonsils.

FAQs About Tonsil Stones

Q: What causes tonsil stones to keep coming back even after you remove them?
A: Tonsil stones return because removing the stone doesn’t remove the conditions that created it. Bacteria, food particles, mucus and dead cells continue to collect inside the tiny folds of your tonsils if your oral hygiene, saliva flow or oral microbiome remain unchanged. Addressing those underlying issues helps break the cycle instead of repeatedly treating the symptoms.

Q: What are the safest ways to remove a tonsil stone at home?
A: Start with the gentlest methods first. Gargling with warm salt water, coughing deeply or using a gentle stream from a water irrigator often loosens small stones without injuring your throat. If the stone is easy to see, a soft cotton swab works carefully in some cases. Avoid sharp objects such as toothpicks because they can puncture the delicate tissue in your tonsils.

Q: Why does mouth breathing increase the risk of tonsil stones?
A: Mouth breathing dries out your mouth, reducing the amount of saliva available to rinse away bacteria and food debris. As your mouth becomes drier, more material stays trapped inside your tonsils, making it easier for stones to develop. Improving nasal breathing helps restore your mouth’s natural cleaning system.

Q: Does your diet affect your chances of developing tonsil stones?
A: Yes. Diet influences the environment inside your mouth. Foods high in refined sugar encourage bacterial growth, while staying well hydrated and eating crunchy foods such as apples and carrots stimulates saliva production, which helps wash away bacteria and loose debris before they become trapped.

Q: When is it time to stop treating tonsil stones at home?
A: Home care works best for small stones that are easy to reach and not causing severe symptoms. If the stones keep returning, become difficult to remove, cause significant pain, interfere with swallowing or breathing, or continue despite good oral hygiene, it’s time to seek a professional evaluation.

Modern agriculture is straining under its own weight — and the soil is paying the price. Across the U.S., topsoil is washing away, microbial life is disappearing, and farmers are going broke trying to prop up a system that wasn’t built to last. What used to be self-sustaining, living ecosystems are now bare, lifeless fields that repel rain instead of absorbing it.

When soil biology declines, more water runs off instead of soaking in — a sequence that’s linked to increased flooding and crop failure.

The root problem is that soil no longer captures sunlight or holds water the way nature intended. Former U.S. Department of Agriculture soil scientist Ray Archuleta has spent decades working with farmers across six continents, and he says the pattern is always the same. Overgrazing, chemical fertilizers, and relentless tillage strip the land of its living cover, leaving it naked, hungry, thirsty, and “running a fever.”1

Archuleta frames this as a measurable breakdown of four core ecosystem processes: sunlight capture, water cycling, nutrient flow, and biodiversity. On his reading, what’s at stake isn’t only soil quality — it’s the foundation of a functioning food system. What many people don’t realize is that these degraded lands aren’t beyond repair.

A biology-based approach is already being applied in the field, and it starts with livestock. Cows, when moved in the right way, can help reactivate dormant ecosystems by fertilizing, stirring, and reseeding the land — much like wild bison once did. Archuleta reports that rotational grazing paired with plant diversity rebuilds topsoil and, on the landscapes he has worked on, has coincided with improved local rainfall and returning vegetation.

That’s why Archuleta’s work is so compelling: it suggests that healing land isn’t about adding more chemicals or inventing new technology. It’s about stepping back and learning how to mimic the architecture of nature itself. Let’s dig into what happens when you do.

Healing the Land Starts with Changing How You See It

In a lecture at the 2024 R-SOIL Conference, soil scientist Archuleta broke down the destructive myths behind conventional farming and laid out a new model based on nature’s original blueprint.2 His focus? Teaching producers to stop treating soil like dirt and start seeing it as a living, breathing ecosystem.

The presentation, published on Matt Powers’ YouTube channel, Regenerative Soil & Permaculture, walks viewers through a decades-long journey of failure, insight, and practical strategies for land restoration that rely on biology rather than synthetic inputs.

• Farmers around the world are dealing with the same problems — and the same wrong mindset — After traveling across six continents, Archuleta observed that most producers, regardless of geography, suffer from the same core issue: a mindset shaped by reductionist science and industrial agriculture.

This narrow way of thinking sees problems and solutions in fragments rather than interconnected systems. Whether in Idaho or India, he found that focusing only on fertilizers, equipment, or outputs misses the larger design — nature’s design — and that design always starts with life in the soil.

• Real recovery begins when you mimic nature instead of fighting it — Rather than relying on synthetic inputs or new technologies, Archuleta stresses the importance of mimicking nature’s architecture: diverse plant cover, tightly managed grazing, minimal soil disturbance, and continuous sunlight capture. This method is visible in ranches he’s worked with in New Mexico, where desert land has been transformed into thriving green pastures using nothing more than animals, fencing, and timing.

• Mindset is the first thing that needs to change — Archuleta says the greatest barrier to regeneration isn’t technical — it’s mental. Farmers conditioned by university training or generational habits resist holistic thinking. Many farmers have been conditioned to beat down anything that challenges the norm, including biological methods that have outperformed conventional ones on the operations Archuleta has worked with.

• The industrial model is bankrupting rural communities — Archuleta presents data showing that most of the wealth generated from agriculture doesn’t stay with the farmer. Charts of U.S. and Canadian farm income show a dramatic decline over time, with most profits now going to agribusiness. The current system leaves many farmers unable to pass their land to their children — not because they lack knowledge, but because they’re trapped in a broken economic and ecological loop.

• Conventional soil looks dead for a reason — Archuleta used simple but powerful demonstrations to drive home his message. In one rainfall simulator test, bare tilled soil shed nearly all the water as runoff, carrying precious topsoil with it. But next to it, a biologically active, covered soil sample absorbed every drop, a visual demonstration of how aggregation and living soil biology affect infiltration.

Another striking test compared soil from a conventional field with soil from a farm using cover crops and no tillage. When dropped in water, the tilled sample disintegrated instantly, while the regenerative soil stayed intact. Why? Because living soils produce “biotic glues” — compounds created by microbes and fungi that bind soil particles into aggregates. These sponge-like structures are essential for absorbing water and holding nutrients.

Healthy Soil Is the Foundation of a Functional Ecosystem

Archuleta’s argument is that the real disruptor isn’t carbon dioxide — it’s bare soil. He challenges the idea that CO2 emissions from human activity are the main issue. Citing NASA satellite imagery, he argues that springtime tillage across croplands contributes to seasonal spikes in atmospheric CO2 across North America — an interpretation that differs from the conventional explanation, which attributes the seasonal cycle mainly to plant dormancy and decomposition.

Unlike industrial sources, planted fields draw that carbon back down — if they’re covered with living crops. When corn and soybeans grow in early summer, they absorb large amounts of carbon through photosynthesis. The real crisis is that bare soil no longer functions as a biological pump. Without plants, it loses its ability to absorb water, store carbon, and regulate surface temperatures.

Archuleta argues that water vapor, more than CO2, drives rainfall and temperature swings and that soil plays a key role in managing it — He explains that water vapor is far more abundant in the atmosphere than CO2 — depending on temperature and humidity, roughly 10 to 100 times as much near the surface.

When soil is hard, bare, or packed too tightly, it can’t soak up water the way it should. That throws off the local water cycle — the natural loop where plants release moisture into the air, which then falls back down as rain.

Archuleta says roughly 40% of the rain that falls over land comes from moisture released by plants and soils rather than directly from the ocean — a figure broadly in line with published estimates of terrestrial moisture recycling.3 When land is bare, it doesn’t hold water or cool the air; it reflects heat instead. That extra heat builds up and in his account, feeds more erratic local weather — longer dry spells, hotter days, and sudden heavy downpours.

Soil isn’t just ground; it’s architecture — One of Archuleta’s core teachings is that soil has a complex design, with multiple functional layers known as spheres: the surface skin (dermis), the rhizosphere (around roots), the porosphere (pore spaces), and more.

These layers coordinate the exchange of gases, water, nutrients, and microbial life. Disturb them with chemicals or tillage, Archuleta says, and the system’s function degrades. Nurture them with plant cover and rest, and the entire soil body becomes a functioning, self-regulating organism again.

Life pulls minerals from rocks, not chemicals — In degraded soils, biology has been replaced with inputs. In nature, it’s the living things in the soil — especially fungi and plant roots — that pull minerals out of rocks. They do this by releasing natural acids and enzymes and by breathing, which helps break the minerals down into a form plants can use.

Archuleta drives this home with images of trees growing out of bare rock faces, illustrating his point that it’s not the nutrients in a bag that matter — it’s the life in the soil that makes minerals bioavailable. Without biology, the soil is just dirt.

• Land can be restored even in extreme conditions — On a ranch in the Chihuahuan Desert, where annual rainfall averages just 10 inches and summer temperatures soar past 105 degrees Fahrenheit, Archuleta documented a full landscape transformation using nothing but rotational grazing and ecosystem mimicry.

Two cowboys moved the herd over 800 times per year, mimicking bison migration patterns. Archuleta reports that grasslands returned, soils darkened, measured rainfall rose over the period he documented, and areas previously thought unchangeable began supporting vegetation again. Note that these are field observations from a single operation rather than controlled research, and the specific contribution of grazing management to the rainfall change has not been isolated.

• The lesson is simple: if you want to heal your land, let nature lead — Archuleta urges farmers to stop trying to dominate nature and start asking, “What would nature do here?” He recommends following resources like the Biomimicry Institute and using simple tools — a shovel, a rainfall test, a visual assessment — to measure success. “Soil without plant and without microbial life is just geology,” he says. “It’s life that brings it out.”

How to Support Regenerative Agriculture and Healthier Soil

You don’t have to be a farmer to help heal the land. Most food choices push in one direction or the other — toward systems that rebuild soil, or systems that deplete it. Right now, conventional agriculture is draining the life out of our soil, and the consequences show up in your food, your community, and your environment.

But regenerative farmers are showing that it’s possible to grow nutrient-dense food while restoring biodiversity, improving water infiltration, and rebuilding soil organic matter. If you want cleaner air, cleaner water, and healthier food, it starts by shifting your support away from industrial systems and toward the farmers who are doing it right. Here’s how to be part of the solution.

1. Buy directly from regenerative farmers whenever you can — Seek out farmers who use cover crops, rotational grazing, composting, and no-till methods. Ask about their practices — not just whether they’re “organic.” Use directories like the Regenerative Farmers of America,4 attend local farmers markets, or join a regenerative community-supported agriculture (CSA) program. When you support these growers, you help fund living systems instead of synthetic ones.

2. Choose meat and raw dairy from animals raised on pasture — Livestock are not the enemy when they’re managed properly. Rotationally grazed cattle, sheep, goats, and poultry can fertilize the land and help restore plant diversity. Look for labels like “100% grass fed,” “pasture-raised,” or better yet, talk directly with the farmer. Dollars spent on meat raised this way go to a system built to rebuild land rather than deplete it.

3. Stop supporting brands that rely on industrial agriculture — Many processed foods, plant-based meat substitutes, and industrial dairy products are made from crops grown on degraded land with heavy chemical inputs — a supply chain associated with runoff, erosion, and soil loss. When possible, avoid ultraprocessed foods and buy from smaller brands that disclose sourcing practices. If a brand can’t tell you how its ingredients are grown, it’s probably not worth supporting.

4. Raise awareness in your community and online — Most people have never seen a soil profile, a rainfall simulator, or the difference between living and dead land. Share content from educators like Ray Archuleta and before-and-after case studies that show real land restoration. Invite your friends to farm tours, local talks, or online webinars. The more people see what healthy soil looks like, the faster this movement grows.

5. Vote with your fork and your voice — Every purchase you make is a signal. Every conversation you start, every farmer you support, every city council comment you submit — those things matter. Advocate for policies that encourage soil regeneration, not chemical subsidies. Support local food programs in schools. Ask your grocery store to carry pasture-raised options.

You have more power than you think when you act consistently and with intention. Healing the land doesn’t just belong to farmers — it belongs to anyone who eats. Your daily choices shape the system. Choose to support the ones working with nature, not against it.

FAQs About Regenerative Agriculture

Q: What is regenerative agriculture and how does it work?

A: Regenerative agriculture is a system of farming that mimics nature’s patterns to restore soil health, increase biodiversity, and improve water retention. It uses practices like rotational grazing, cover cropping, and minimal soil disturbance to build living soil biology, which supports healthier plants, builds soil organic matter, and reduces the need for synthetic inputs.

Q: Why is conventional farming damaging the land?

A: Conventional agriculture relies on heavy tillage, chemical fertilizers, and monocultures. These practices break down soil structure, reduce microbial life, and leave the ground bare, which contributes to water runoff, erosion, and loss of fertility. As Archuleta explained, this has turned once-thriving land into lifeless dirt that repels rain and contributes to environmental problems.

Q: How do cows help regenerate soil instead of harming it?

A: When managed properly through rotational grazing, cows fertilize the land with manure, spread seeds, and stimulate plant growth, just like wild herds once did. Moving livestock frequently allows grasslands to rest and regrow, rebuilding soil structure and increasing water infiltration. This turns animals into tools for healing degraded ecosystems.

Q: What can I do if I’m not a farmer?

A: You can support regenerative agriculture by buying directly from farmers who use regenerative practices, choosing pasture-raised meat and dairy, avoiding processed foods grown with industrial methods, and spreading awareness. Every food choice you make helps support or dismantle the current system.

Q: How does healthy soil impact me personally?

A: Living soil tends to produce more nutrient-dense food, holds water better during droughts, and supports cleaner air and water. It also stores more carbon as organic matter — which is part of what gives it that water-holding capacity in the first place. Supporting regenerative systems means investing in your own health, your community’s resilience, and the future of the planet.

Three years ago, a nationwide infant formula shortage shook America, and before long led to fights at grocery stores1 and stories like this flooding the media:

At the time, significant outrage was directed at the FDA since the shortage was due to their inspection triggering a major recall by one of the leading formula manufacturers (along with tight supplies and subsequent panic buying).

Furthermore, many could not grasp why the FDA was willing to enact such a strong enforcement action against potentially contaminated infant formula which was linked to two deaths. Still, they had no issue with the large numbers of people dying from the COVID vaccines nor the immense degree of contamination and deadly hot COVID vaccine lots the public had discovered.

As I watched this unfold, my thoughts were a bit different. Could there possibly be another way to feed your infants? Perhaps one that you could do at home that did not rely upon an unstable supply chain — but surprisingly, I did not see that offered anywhere (even in homesteading groups).

I thus took the events of 2022 as a remarkable testament to just how effectively the formula industry had convinced mothers they needed to do anything besides breastfeed their children, and since then, have tried to help create a window to end this dysfunctional paradigm.

Fortunately, on March 18th, RFK Jr. announced an FDA initiative2 to make America’s infant formula healthy again (e.g., conducting a comprehensive review of its nutritional content, testing formula for heavy metals, and objectively assessing the health issues that arise from formula feeding). This is extremely important and I believe that for “Operation Stork Speed” to succeed,3 it’s critical for us to understand what went awry with infant formula.

Note: In addition to heavy metals4 (and other harmful chemicals), infant formula has also repeatedly been found to be contaminated with aluminum,5 something which is quite problematic due to its adverse effects on the physiologic zeta potential6 (which can cause microclots in the nervous system).

The History of Formula Feeding

Throughout history and cultures, there are references to (likely malnourished) mothers who could not sufficiently nourish their children with their breast milk, who then sought out milk from other mothers or, if that was not available, from animals.

This process led to a variety of attempts (starting in 1865)7 to create a milk substitute that more accurately matched the safety and efficacy of human breast milk, a process which was revolutionized through the discovery of evaporated milk powder and its adaptation into infant formulas in the early 1900s.

As infant formulas improved in the 1920s,8 manufacturers began targeting physicians with their advertising. By 1929, the American Medical Association (AMA) established a committee to evaluate the safety and quality of formula compositions, leading many companies to seek the AMA’s “Seal of Acceptance,” bringing physicians closer to formula manufacturers.

By the 1940s and 1950s, formula use became widely accepted as a safe alternative to breast milk, and with the help of aggressive marketing and the inappropriate medicalization of childbirth, successfully displaced breastfeeding.9

Note: The AMA’s seal of approval was created in 1905,10 and was designed to be a source of revenue to keep the struggling organization afloat (as it was given in return for advertising dollars rather than any assurance of safety11 — for instance the AMA widely promoted the benefits of smoking their sponsor’s cigarette brand).

Sadly, once this funding allowed the AMA to begin establishing a foothold in the medical market, the organization then switched to blacklisting every competing therapy which would not sell out to the AMA12 (which is essentially why there are so many remarkable forgotten medical therapies exist emerged in the early 1900s).

Many recognized this shift was harmful to both mothers and children, so a variety of groups (particularly the La Leche League13) mobilized the public to support mothers breastfeeding. In the 1970s, they finally reached the public (due to both scientific data emerging in support of breastfeeding and a growing societal dissatisfaction with the paternalistic and insensitive attitude medicine had towards women). Since then breastfeeding has gradually made a comeback.

One of the key events that catalyzed this shift away from formula was the Nestlé formula scandal (which began in 197314), which began after the public learned Nestlé was aggressively targeting poor women in undeveloped countries for infant formula sales.

This was accomplished by paying hospitals to give free samples to mothers after delivery and telling mothers (frequently via sales reps impersonating nurses) that they would not be able to produce enough milk for their babies. This, in turn, created anxiety that suppressed maternal milk production and led to the impoverished mothers frequently not only switching to infant formula but also diluting it (as they could not afford standard doses).

Millions of infants died as a result of these practices,15 and Nestlé eventually came under widespread public scrutiny (e.g., boycotts, celebrity protests, government investigations, and some of its predatory marketing practices being banned).

The fact that Nestlé was able to convince millions of mothers to starve their babies to death again illustrates how predatory many of these marketing tactics were16 (particularly since some of those now outlawed practices still continue in the poorer nations).

Formula Marketing

During pediatric “well-child” visits, doctors frequently diagnose children as underweight based on growth charts and then promote (frequently unnecessary) infant formula17 that routinely contains unhealthy ingredients like obesity promoting corn syrup and seed oils.

Note: This is somewhat analogous to how a widely used (but erroneous) calculator routinely tells patients they are at high risk of a heart attack and hence must start a dangerous and unnecessary statin.

Robert S. Mendelsohn,18 in How to Raise a Healthy Child In Spite of Your Doctor,19 critiqued this, noting industry sponsored growth charts often favor formula-fed children, misclassifying breastfed babies as “underweight.”

This is particularly true for CDC’s charts as their weights are derived from too many formula fed babies,20 and hence can diagnose breastfed babies as “underweight.” Hence, formula-feeding is promoted as the “new normal” despite studies showing it leads to rapid weight gain and adult obesity.21,22,23

As such, the formula’s role in the continually increasing childhood obesity rates24 (e.g., 19.7% in 2020)25 must be considered (but unfortunately, we are instead “solving” it by putting children on Ozempic26 — a drug which has a great deal of issues).

This again illustrates the longstanding tendency of the formula industry to engage in a variety of predatory tactics (e.g., making a variety of false claims not supported by the existing evidence to create parental anxiety, funding pediatrician’s “education,” having the doctors and hospitals push unhealthy infant formula, levying sanctions against countries that promote breastfeeding and lobbying against laws allowing maternity leave27).

Sadly, due to that (and spending 3 billion each year on marketing) the formula industry now has a 10.15% annual growth rate and an annual market worth 90.91 billion.28

So while breastfeeding has many proven health benefits, less than 50% of babies worldwide are breastfed according to WHO recommendations — which results in nearly $350 billion dollars of economic losses annually.29

Seed Oils in Formula

Since seed oils are linked to obesity, inflammation, and metabolic dysfunction, many parents do not want to give them to their children. In turn, I am frequently contacted by frustrated patients after they discover that every infant formula is full of seed oils. This is because:

• FDA regulations require infant formulas to have at least 2.7% of its calories (300 mg per 100 Kcal) come from linoleic acid (LA, the problematic omega-6 fat in seed oils), which the FDA aggressively enforces. The regulations have no upper limit, resulting in some formulas containing over 15% LA.

• The Infant Formula Act of 1980 is the source of that FDA regulation.30

• Its requirements came from 1960s research that erroneously deemed LA essential for infant development (largely because infants consuming no other fats would have their skin dry out).

• Modern science shows that the required amount of LA is much lower once other essential fats are present,31 that high LA blocks the synthesis and accumulation of fats which are critical for brain and eye development (hence impairing neurological development), and that LA increases the brain’s vulnerability to inflammation.32

Because of this, other governments (e.g., China’s33 and Europe’s34) have revised their infant formula requirements. Remarkably however, despite the Infant Formula Act granting H.H.S. Secretaries the authority to update the nutritional requirements of infant formula since 1980, all they’ve done is slightly raise the required phosphorus and calcium and require the addition of selenium to formula (which ultimately happened 26 years after the scientific community concluded it was essential).

As such, many fats we now know are essential for developing infants are largely absent from formula, and simultaneously, LA remains a primary ingredient (likely on account of industry lobbying as LA is one of the cheapest ingredients available to the food industry).

Raw Milk

Throughout history, infants in many societies whose mothers could not produce sufficient milk have gotten supplemental milk from a variety of animals, and in America, prior to World War II, many textbooks advocated for feeding children raw animal milk.35

At the time pasteurization began to be implemented for milk in the late 1800s,36 it was arguably immensely valuable as while millions of children had been successfully raised on raw animal milks, children were also being sickened by microbial contaminated milk (as things were much less sanitary then than they are now and not every children had access to clean cow’s milk).

As such, before long, humanity’s long history of consuming raw milk was forgotten and raw milk came to be viewed as extremely dangerous (largely due to raw milk significantly increasing the risk of causing a listeria infection — something which can be quite hazardous to mothers, children, and the elderly).

However, the data does not support that belief. For example, a (likely biased) 2003 risk assessment from the FDA found many commonly consumed foods (that no one ever objects to) had a much greater risk of causing a listeria infection than raw milk.37

Similarly, a 2007 FOIA request showed that from 1980 to 2005, there had only been three total cases of listeria and two of brucella (all of which came from raw cheese not raw milk) and that all other microbial infections in raw milk (most of which aren’t that dangerous) were also quite rare (typically under a 100 cases per year).38

Note: While raw milk is relatively safe (provided you get it from a clean and grass fed source), there is a small elevated risk of infection from soft raw cheeses.

In contrast, pasteurizing milk damages essential vitamins and denatures proteins, leading to issues such as:

The loss of beneficial enzymes.
Denatured proteins lose their negative charge, thereby adversely affecting the physiologic zeta potential (which in turn can create congestion throughout the body).
Pasteurized milk can turn proteins into allergens, leading to allergies, rashes, and respiratory problems like asthma — whereas raw milk rarely causes those issues.

Note: While still problematic, evaporated milk causes fewer allergies than liquid pasteurized milk. Additionally, some individuals who have difficulty consuming dairy find switching from A1 to A2 milk (which is much rarer than A1 milk) improves their symptoms, while others better tolerate goat’s milk (but also can cause constipation and lacks B₁₂). However, while each can be helpful, in most cases, individuals best tolerate raw milk.

Conversely, the plant “milks” can be quite problematic for infants as they lack many of the essential nutrients found in animal milks and often contain various unhealthy substances. Soy milk is particularly problematic due to the high amount of phytoestrogens soy puts into the bloodstream,39 soy’s effect on thyroid function,40 soy’s frequent contamination with other chemicals (e.g., herbicides), and soy’s tendency to block the absorption of many critical nutrients.41

In short, if a formula is consumed, it is vital that it safely meets an infant’s nutritional needs. Consequently, many have observed, infants fed on those natural formulas (or breast milk) thrive and lack many of the illnesses seen in most infants.

The Benefits of Breast Milk

One of the most reliable approaches for creating a successful business is to replace something (free) that people rely upon with a patentable product. Unfortunately, when this happens, the synthetic substitute is often a meager shadow of what it replaces.

Breast milk, for example, is a complex, nutrient-rich substance that is crucial to infant health and development.42 It contains growth factors, antibodies, cytokines, and enzymes that support the immune system, digestive health, and overall growth.43,44,45,46

MicroRNA47 in breast milk helps regulate gene expression, prevents allergies, and aids in immune development. Unique to breast milk, these components provide immune protection and foster a baby’s development in ways formula cannot fully replicate.48

Breast milk also contains essential fatty acids,49 cholesterol,50 human milk oligosaccharides,51 (and many other unique lipids)52 that are critical for brain development,53 eye development54 and cognitive function (e.g., academic success55).

These nutrients are absent or less abundant in formula, making breast milk a superior choice for infants. Additionally, it offers bioavailable nutrients,56 reducing nutrient competition (e.g., for zinc absorption).57 The benefits of breastfeeding are numerous and include:

• Lower rates of infections (e.g., pneumonia,58 ear infections59) and lower hospitalization rates (e.g., for infections).60

• Lower rates of gastrointestinal issues (e.g., stomach problems,61 constipation,62 gas,63 diarrhea64) and allergies65 (e.g., being half as likely to develop asthma66).

• Being half as likely to die67 from Sudden Infant Death Syndrome68 (a condition decades of evidence shows is linked to vaccination).

• Being less likely to develop cancers69 (particularly leukemia70).

• Improved brain development (particularly white matter growth71).

• Improved cognition (e.g., verbal and spatial skills72 or mathematical ability and working memory73). Likewise, breastfeeding for 12 months was associated with a three-point increase in IQ74 (along with a 0.8 point increase for each additional month75), and higher educational and financial success in life.76

• Being significantly less likely to develop autism or ADHD.77

Breastfeeding also offers significant benefits to the mother, both immediately after pregnancy and later in life. In the short term, it promotes better infant bonding,78 enhances maternal mood,79 aids in post-pregnancy weight loss,80 and reduces the likelihood of developing postpartum depression.81

Additionally, breastfeeding over 12 months of breastfeeding reduces the risk of breast cancer by 4.3%,82 ovarian cancer by 34%83 (and by up to 91% with extended breastfeeding84), and also decreases the risks of endometrial cancer,85 heart attacks,86 and high blood pressure.87

Breastfeeding also promotes stronger bonding, aids in postpartum weight loss, and improves maternal mood. In short, the complexity and richness of breast milk and the mother-child bond it fosters make it an unparalleled source of nutrition, providing essential support for both infant and mother.

As such, it is always imperative that mothers are given the proper support to nourish their children (e.g., lactation consultants can be immensely helpful).

Similarly, one of the most important, but frequently missed points is that the mother needs to be supported as much as possible during the post-delivery process (e.g., with maternity leave and a supportive family), since stress (particularly chronic stress) frequently significantly decreases milk production. In contrast, if her well-being is prioritized, the other necessary areas (e.g., the marriage and the infant’s health) tend to work themselves out.

Conclusion

In my eyes, there are three reasons why the issues I’ve outlined here are so important:

• First, it is a fundamental aspect of human life which (like many other things) industry has usurped from us and replaced with an inferior product that takes away our independence and health.

• Second, our early nutrition during childhood sets the stage for the rest of our lives. As such, we must reclaim a healthy way to raise our children, particularly since many of the principles for a healthy infant diet also hold true for the rest of one’s life.

• Third, infants raised on nutritious breast milk or formula tend to be much healthier, and many people I’ve spoken to over the years notice those differences.

RFK Jr., through his newly enacted “Operation Stork Speed,”88 is taking a stand to reform the formula industry, update the science, and protect our families. For this to succeed, we too must do all we can to make the food we feed our children healthy again, and I am deeply grateful that an opportunity like this is at last before us.

Do you enjoy alcoholic drinks every now and then? While it’s commonly believed that moderate drinking is fine,1 growing evidence suggests that alcohol, even in modest amounts, may harm your body. Previous research has shown that it increases your risk for premature death and cancer. Now, there’s a growing body of evidence showing that it also damages your brain, and may increase your risk of dementia.

Any Intake of Alcohol Raises Your Risk for Brain Damage

A study published in Neurology explored how alcohol consumption affects the brain over time, particularly in older adults.2,3 Researchers, based in Brazil, examined brain autopsies from 1,781 people who have an average age of 75 years old at death. Then, they compared those findings to how much alcohol each person drank throughout life as reported by family members. Here’s what they found:

• Defining the parameters of the study — The participants were split into four groups — those who never drank, moderate drinkers (up to seven drinks per week), heavy drinkers (eight or more drinks weekly), and former heavy drinkers who had quit.

A single drink was defined as containing 14 grams (g) of alcohol, which is roughly equivalent to 350 milliliters (mL) of beer, 150 mL of wine, or 45 mL of liquor.

• Those who drank regularly had more vascular brain lesions — Among heavy drinkers, 44% had vascular brain lesions. That compares to 40% for those who never drank, and 50% for former heavy drinkers.

Vascular brain lesions are also known as hyaline arteriolosclerosis, which is the thickening and stiffening of the small blood vessels in your brain. These lesions reduce blood flow (thus oxygen delivery) to brain cells, which may contribute to tissue damage, cognitive dysfunction, and long-term memory problems.

• The presence of lesions persisted even after quitting — Even former drinkers who quit years before death showed lasting damage. This suggests alcohol’s impact on your brain is not only acute, but also cumulative.

• Your lifestyle greatly influences the risk for brain lesions — After adjusting for other health factors like smoking, exercise, and age, heavy drinkers had a 133% higher chance of developing these brain lesions compared to those who never drank.

Former heavy drinkers weren’t far behind, with an 89% increased risk. Even moderate drinkers still had a 60% higher risk for brain damage than lifelong abstainers.

• Alcohol increases your risk for dementia — In addition to vascular damage, the researchers also examined another biomarker of brain degeneration called tau tangles. These are abnormal protein clumps that interfere with neuron function and are linked to Alzheimer’s disease.

Heavy drinkers had a 41% higher risk of developing tau tangles, while former heavy drinkers had a 31% increased risk compared to those who never consumed alcohol.

• Former heavy drinkers had a significantly lower brain mass ratio — This means this test group’s brains were smaller relative to their body size. Shrinking brain mass may set the stage for poor memory, slower thinking, and more difficulty managing daily tasks. Worse yet, this group also scored lower in cognitive function tests.

• Drinking is linked to a shorter lifespan in this study — Heavy drinkers died an average of 13 years earlier than those who never drank.

The findings raise serious concerns. Even if you feel fine now, and even if your drinking is within what’s often defined as “moderate,” your brain may be experiencing asymptomatic injury. These findings raise serious doubts about the assumption that a beer here or there is harmless.

Further Research Shows That No Alcohol Intake Is Safe for Your Brain

A study published in eClinicalMedicine set out to answer a long-standing hypothesis — does alcohol cause dementia, or are the two loosely associated?4

To answer that, researchers analyzed data from 313,958 United Kingdom (U.K.) participants who currently drank alcohol, all of whom were free of dementia when the study began (2006 to 2010). Over a follow-up period that lasted until 2021, researchers tracked those who developed dementia. They categorized alcohol consumption levels and matched these to genetic profiles designed to estimate lifelong alcohol exposure.

• Genes leaning toward higher alcohol intake were more at risk for dementia — Using individual-level analysis, researchers found that every increase in genetically predicted alcohol consumption pushed dementia risk higher. Interestingly, the strongest effects were seen in women. As noted by the researchers:

“Our analyses found a distinctly more significant association between alcohol consumption and dementia risk among women drinkers … who typically had lower rates of other risk factors, such as smoking, compared to men. For men, the presence of multiple risk factors could mask alcohol’s specific effects.”5

• The study also invalidated the idea that there’s a safe range for drinking — The researchers looked for a non-linear relationship — a curve where low-level drinking might be neutral or even protective, but didn’t find one. “Our findings suggested that there was no safe level of alcohol consumption for dementia,” the authors wrote.

• The data is clear regarding alcohol consumption — To check their results, the researchers created positive control criteria — a known consequence of alcohol use — such as alcoholic liver disease. Their model showed that people with alcohol-promoting genes had a much higher risk of liver damage.

Then, the researchers used age as a negative control (something alcohol doesn’t influence) and found no relationship. These comparisons confirmed that their models were functioning properly, and that the dementia link was genuine — not a statistical coincidence.

Cut Back on Alcohol and Repair the Damage Before It’s Too Late

I’ll admit that I bought into the many common myths about alcohol. I used to drink alcohol a few times a year, believing that it was relatively harmless — and even beneficial. But after diving into the research further, I’ve changed my stance.

Now, I don’t drink any alcohol at all, and I recommend you do the same. If you’re drinking regularly, even a few drinks a week, you may be putting your cognition at risk. As noted by the research earlier, there is no safe level of alcohol when it comes to protecting your memory, your ability to think clearly, or your overall brain health. It’s time for you to take control of your brain health again, starting with these strategies:

1. Cut your alcohol intake to zero — The most important step is to stop the damage at its source. If you’re drinking daily, or even several times weekly, this may be impairing blood flow to your brain and contributing to shrinkage in the areas responsible for memory and cognition.

If you’re not ready to quit completely, start by eliminating weekday drinking or limiting yourself to special occasions. But remember, “moderation” isn’t protective like some have suggested — the evidence increasingly challenges that idea. Your brain is better off without it.

2. Take N-acetylcysteine (NAC) before and after occasional alcohol use — It’s thought to support the liver’s handling of acetaldehyde, a byproduct of alcohol metabolism, though this is not a substitute for reducing alcohol intake.

If you choose to explore NAC or B-vitamin support around alcohol use, talk to a healthcare provider about whether it’s appropriate and what dose may make sense for you. But as mentioned earlier, there’s still no substitute for avoiding alcohol completely.

3. Replace alcohol with beverages that nourish you — If alcohol is your way to unwind, reward yourself, or deal with stress, it’s time to change your routine. Switch to other drinks, such as teas, freshly homemade juices with pulp, or pure sparkling water with natural flavors added.

4. Rebuild your mitochondria with healthy carbohydrate intake — Alcohol can impair mitochondrial function. To restore it, you need fuel, and that is glucose.

I recommend aiming for 200 to 250 grams of carbs per day, mostly from sources like white rice, fruit juices with pulp, and whole fruits. This gives your body what it needs to produce adenosine triphosphate (ATP), the energy currency of every cell, especially brain cells. And if you’ve struggled with brain fog or fatigue before, this shift alone has the power to drastically change your health for the better.

5. Start healing your gut to reduce endotoxin load — Alcohol may damage your gut, allowing endotoxins to be produced. Endotoxins are bacterial fragments that leak into your bloodstream and may contribute to inflammation, especially in your brain. To repair your gut, again, stop drinking alcohol. Moreover, add fermented foods into your diet to diversify your gut flora, allowing better crosstalk between your gut and brain.

Strategies for Eliminating Alcohol Consumption

Are you having trouble quitting alcohol? Dr. Brooke Scheller, founder of Functional Sobriety (a nutrition-based program for alcohol reduction) and author of “How to Eat to Change How You Drink,” offers several helpful tips:

1. Get curious and educate yourself — Read books, listen to podcasts, and learn about the health impacts of alcohol.

2. Find community support — Scheller runs an online community called the Functional Sobriety Network. There are many other support groups and resources available as well.

3. Examine your social media — Unfollow accounts that glamorize drinking and follow sober influencers instead.

4. Address the root causes — Look at why you drink — stress, social pressure, habit — and find healthier alternatives.

5. Support your body nutritionally — Supplements like L-theanine, L-glutamine, NAC, B-complex vitamins, and milk thistle are commonly used by some people to help with cravings and support detoxification.

6. Stabilize blood sugar — Increasing protein intake and eating regularly helps reduce alcohol cravings.

7. Be open about your choice — Scheller encourages people to simply say they’re not drinking for their health if asked.

One of the most powerful shifts Scheller advocates for is changing how you think about alcohol in your life in order to reframe your relationship with drinking:

“Previously, the only people who did quit drinking were people that identified themselves as having a problem or maybe had to quit. And so the first thing I’ll say if you’re listening and you’re interested is you don’t have to have a problem to decide that you want to explore this.

You don’t need to even be that regular of a drinker for you to say, ‘You know what? This is something I may want to explore.'”

In other words, choosing not to drink alcohol is a positive, empowering decision for your health and longevity — not a punishment or deprivation.

Frequently Asked Questions (FAQs) About the Impact of Alcohol on Brain Health

Q: Is moderate drinking safe for my brain?

A: No. Even moderate drinking — defined as seven or fewer drinks per week — raises your risk for vascular brain lesions by 60% compared to people who never drank alcohol. These lesions reduce blood flow and oxygen in your brain, which may contribute to cognitive decline and memory issues over time.

Q: Does quitting alcohol reverse the brain damage?

A: According to the research, the answer is no. Former heavy drinkers in the study had even more brain lesions than current heavy drinkers and showed lower brain mass ratios and worse cognitive function. This suggests alcohol’s damage is long-lasting and accumulates over time, even after you stop.

Q: What exactly does alcohol do to the brain?

A: Alcohol has been linked to hyaline arteriolosclerosis, which is the hardening and narrowing of the brain’s small blood vessels. It also increases tau tangles, which are abnormal proteins linked to Alzheimer’s disease. These changes are associated with shrinking brain tissue, impaired memory, and reduced your ability to think clearly and manage daily tasks.

Q: Is there any safe level of alcohol that doesn’t affect dementia risk?

A: No. Genetic analysis from over 313,958 people showed a direct link between alcohol intake and dementia risk. Researchers found no evidence of a protective effect at any level of drinking — dementia risk increased steadily with every uptick in alcohol consumption.

Q: How can I protect my brain if I’ve been drinking regularly?

A: Start by eliminating alcohol completely to stop further damage. Support your detox pathways with N-acetylcysteine (NAC), repair your mitochondria with healthy carbs like fruit and white rice, and rebuild your gut by avoiding alcohol and adding fermented foods. These steps may help support brain function and reduce further damage.
