Dr. Joseph Mercola - Take Control of Your Health

Every so often, someone takes an industry that had become cold and complicated puts the humanity back into it. The way we take supplements is overdue for exactly that For decades, supplements were one of the least human corners of health, requiring people to take fistfuls of pills and capsules and maintaining a dosing schedule that was easily forgotten on a busy day This article series has presented one idea from several angles: removing the burden that makes people quit, retiring the pill pile, abandoning the mega-dose game, and meeting the inevitable backsliding with forgiveness instead of shame Underneath all...

Vestibular migraine often causes dizziness, imbalance and motion sensitivity without a severe headache, so many people spend months or even years treating the wrong condition before receiving the correct diagnosis Looking at all of your symptoms together instead of treating each one separately makes it much easier to recognize vestibular migraine and begin a treatment plan that targets the underlying neurological problem Keeping a detailed symptom journal helps uncover your personal trigger pattern, allowing you to identify factors such as poor sleep, stress, skipped meals, weather changes or certain foods before they lead to another attack Symptoms such as brain...

Research consistently finds that strokes cluster in the morning, roughly between 6 a.m. and noon, rather than spreading evenly across the 24-hour day A meta-analysis of 11,816 strokes and a systematic review of 58 studies both linked this window to higher stroke onset across ischemic, hemorrhagic, and transient ischemic attacks Scientists attribute the pattern largely to normal circadian shifts, including the blood pressure surge on waking and morning changes that make the blood more prone to clotting Strokes that begin overnight are often recognized late and have been associated with greater severity, which makes knowing the sudden warning signs especially useful Experts...

Having both excess body fat and low muscle mass and strength increased the risk of developing Type 2 diabetes by more than 3.5 times, showing that muscle health is just as important as body weight for protecting your metabolism Your diabetes risk changes as your body composition changes, meaning that building and preserving muscle while reducing excess body fat helps shift your long-term metabolic health in the right direction Women and adults younger than 60 experienced a greater increase in diabetes risk from poor muscle health than other groups, highlighting the importance of protecting muscle long before older age Two people can weigh...

A nutritional supplement regimen is only helpful when it fits the way you actually live Health communication research suggests narrative messages can influence health intentions when people identify with the story being told. Identification matters because it turns a health message from something abstract into something you can recognize in your own day A practical supplement routine reduces friction that can otherwise derail the best of intentions. For example, a scoop of nutritional powder added to food you already eat makes adherence as easy as adding spice to your meal, and makes restarting after a missed day or week easy...

Long-term xanthan gum consumption triggered measurable inflammation in the colon of otherwise healthy rats, even though their weight, blood sugar and cholesterol remained normal, suggesting digestive changes can develop before routine health markers reveal a problem Researchers found that xanthan gum altered proteins that help maintain the gut's protective barrier, making the intestinal lining more permeable and allowing inflammation to become established The study also found subtle shifts in specific groups of gut bacteria that occurred alongside inflammation, indicating that repeated xanthan gum exposure affected both the gut microbiome and the intestinal environment Xanthan gum is widely used in processed...

GLP-1 medications lower body weight, but rapid weight loss often includes muscle loss, which reduces strength, slows your metabolism and makes it easier to regain weight after stopping the medication Simply eating less doesn't guarantee better health. Preserving muscle through adequate protein intake and regular resistance exercise is essential if you want to improve your long-term metabolic health instead of just lowering the number on the scale National Poison Center data show reports involving GLP-1 medications rose sharply after semaglutide received FDA approval for chronic weight management, with many cases involving accidental dosing mistakes and a growing number requiring medical...

Researchers identified 111 PFAS-containing active ingredients used in human medicines and found that 87% already have a PFAS-free alternative available, with alternatives in development for nearly all of the rest, challenging the idea that these "forever chemicals" are required in modern pharmaceuticals Fluorine is usually added to medicines to improve stability or how they move through your body, not because it provides the medicine's therapeutic effect, meaning many drugs could deliver the same benefits without PFAS More than 80% of the PFAS-containing medicines examined break down into trifluoroacetic acid (TFA), a highly persistent environmental contaminant that's extremely difficult to remove once it reaches...

People with healthier chest and back muscles had a significantly lower risk of both heart attack and early death over the next 10 years, suggesting that muscle quality may be an important marker of long-term heart health The condition of the muscles mattered more than their size; muscles with less fat trapped inside the fibers were linked to better cardiovascular outcomes than simply having larger muscles Strong chest and back muscles remained associated with a lower heart attack risk even after researchers accounted for age, sex, and calcium buildup in the arteries, suggesting muscle quality provides important information beyond conventional heart...

Research suggests that spending more time in bright daytime light was linked to a lower risk of developing dementia, with measurable brightness targets that are often reached outdoors. However, the researchers caution these thresholds may not transfer directly to other populations In the study's machine-learning analysis, bright daytime light ranked as a stronger predictor of future dementia risk than several familiar factors, including alcohol consumption, obesity, hearing loss, and traumatic brain injury The strongest association between brighter daytime light and lower dementia risk was found in people already at higher risk, including those with an evening chronotype and people who...

Most Americans favor clear definitions and practical dietary guidance about ultraprocessed foods over taxes, suggesting that better information is the policy change people want most Federal dietary guidelines now advise limiting highly processed foods for the first time, reflecting growing scientific concern that diets built around these products are linked to higher risks of chronic disease In a tightly controlled feeding study of 20 adults housed in a metabolic ward, those who ate ultraprocessed foods consumed about 500 more calories per day than those who ate minimally processed foods, even when the diets contained similar amounts of nutrients Learning how to identify...

For decades the supplement industry has competed in one direction only — toward more ingredients, more milligrams, more capsules — on the unspoken assumption that more is better and a complex, multi-ingredient supplement is better than a simpler one with fewer ingredients The complexity of many supplement routines works against the only outcome that matters — whether you take it, consistently, for long enough to make a difference Higher doses do not guarantee that more reaches your cells. In a poorly absorbed form, a larger dose simply means more is wasted Simplicity is the harder achievement; it's easy to throw more into a bottle...

Long-term residential exposure to the insecticide chlorpyrifos was associated with more than a 2.5-fold higher risk of developing Parkinson's disease, adding to growing evidence that certain pesticides may pose a significant risk to brain health Researchers strengthened the findings by showing that chlorpyrifos produced similar Parkinson's-like changes in laboratory animals (via mice exposed by inhalation over 11 weeks), including loss of dopamine-producing nerve cells, harmful protein buildup, and chronic brain inflammation The pesticide disrupted the brain's natural recycling system in these animal models, allowing damaged proteins to accumulate inside nerve cells instead of being cleared away, which may help explain how...

Previous research, including the large COSMOS clinical trial, found that consuming about 500 milligrams (mg) of flavanols daily was associated with a lower risk of dying from cardiovascular disease and fewer major cardiovascular events. However, note that COSMOS tested a cocoa extract supplement rather than food, enrolled adults aged 60 and older, and the reduction in major cardiovascular events came from a post hoc analysis The featured study found following current fruit and vegetable recommendations didn't provide enough flavanols for most people to reach the intake linked with better heart health, showing that which foods you choose affects flavanol intake more than...

Non-stimulant pre-workout supplements may improve exercise performance by supporting your muscles' natural energy production, blood flow, and recovery instead of relying on large doses of caffeine to keep you alert Creatine remains one of the most researched non-stimulant ingredients for supporting increases in strength, power, and the number of quality repetitions you complete during high-intensity training Beta-alanine works only after consistent daily use because your body converts it into carnosine, a compound that helps your muscles resist fatigue during demanding exercise Reading the ingredient label is just as important as choosing the supplement itself because proprietary blends often hide ingredient...

Dehydrated foods last longer because water removal slows spoilage, but the process also concentrates sugars, calories, salt, and other ingredients into much smaller portions Dried fruits retain fiber and plant compounds, yet research on their effects on blood sugar, cholesterol, and blood pressure remains mixed, especially when they add extra calories instead of replacing processed snacks Prunes showed the clearest evidence for digestive and bone support, with studies linking regular intake to more frequent bowel movements and better preservation of hip bone density in postmenopausal women Drying method matters: conventional hot-air drying caused far larger losses of vitamin C in...

Cancers diagnosed before age 50 increased 24% worldwide between 1990 and 2019, while younger generations also show signs of faster biological aging Biological age reflects the condition of your cells, tissues, and organ systems, giving you a more complete picture of your health than chronological age alone Faster biological aging was associated with higher risks of early-onset lung, gastrointestinal, and uterine cancers, although the strength of these links varied depending on how researchers measured aging Different parts of your body age at different rates, with faster immune system aging linked to early-onset lung cancer and accelerated fat tissue aging linked to early-onset colorectal cancer...

Long-term exposure to even moderate levels of air pollution was associated with more calcium buildup, more plaque and more advanced coronary artery disease, suggesting your heart is affected long before symptoms appear Women exposed to higher levels of fine particle pollution were about 80% more likely to have severe blockages in the arteries supplying the heart, highlighting that air pollution doesn't affect everyone equally Ultrafine particles from vehicle exhaust, industrial emissions, power plants and gas stoves are even smaller than the pollutants measured in the study, travel throughout your body after entering your lungs and outnumber microplastics by an enormous margin...

Spending most of your day sitting increases your risk of chronic disease and early death, but taking a five-minute walk every hour is a simple habit that helps counter many of those harmful effects Researchers found that hourly walking breaks offered the best balance between meaningful health benefits and a routine that people could realistically maintain, while also improving mood and reducing fatigue without hurting work performance You don't need to reach 10,000 daily steps before your health improves; increasing your daily total to about 4,000 to 4,500 steps was associated with substantial reductions in the risk of death and cardiovascular disease The...

When it comes to maintaining a nutritional supplement regimen, the decisive question is not "what's in the bottle" — it's what makes a person actually take it, day after day, long after the first burst of motivation fades Motivation behaves like weather: it rolls in and rolls out. Any routine that depends on feeling inspired every morning is built on sand Friction is where habits die. Every extra step becomes another reason to skip a dose, and people rarely quit a supplement routine in one dramatic moment; they drift, one missed dose at a time We are creatures of cue and co...

UCLA researchers found that creatine may do more than support muscle performance; early research suggests it also helps power key immune cells that coordinate the body's defense against cancer When immune cells were unable to absorb creatine, they showed lower survival, weaker activation, and a reduced ability to stimulate the T cells responsible for attacking abnormal cells Creatine helped immune cells maintain higher levels of ATP, the body's primary cellular energy source, allowing them to stay active and communicate more effectively In a mouse melanoma model, creatine supplementation was linked to slower tumor growth, more active immune cells inside tumors...

A study of more than 31,000 adults with Type 2 diabetes found that a widely prescribed class of blood pressure medications was associated with a 33% higher risk of serious kidney complications, including substantial loss of kidney function, dialysis or transplantation The increased kidney risk persisted even though all participants were already taking modern kidney-protective therapies that are considered standard treatment for diabetic kidney disease Researchers believe these medications may increase pressure inside the kidneys' filtering units, exposing already damaged tissue to additional mechanical stress, which may accelerate kidney decline High blood pressure not only raises the risk of heart disease but also...

Vitamin K does far more than support blood clotting; research in mice found it helps regulate the constant cycle of removing old bone and building new bone — a process that influences long-term bone strength Researchers identified a vitamin K-dependent protein called GAS6 that acts as a messenger between bone-building cells and bone-removing cells, helping coordinate the remodeling process that keeps your skeleton healthy Bone-building cells use vitamin K at remarkably high levels; researchers found that the enzymes responsible for vitamin K activity were 10 to 40 times more abundant in bone-building cells than in bone-removing cells, a sign that bone-building cells are am...

Researchers found that Wegovy showed the strongest reported association with a rare optic nerve injury that can cause sudden vision loss, raising new questions about the safety of high-dose semaglutide formulations Men using Wegovy showed the highest reported risk in the FDA safety database, with odds of optic nerve injury appearing substantially higher than those reported for women Analysis of more than 400,000 online discussions revealed that many GLP-1 users frequently reported fatigue, low energy, menstrual changes, chills and hot flashes — symptoms that receive far less attention than digestive side effects Real-world patient conversations and artificial intelligence analysis are helping researchers id...

Your digestive system continues healing long after vomiting and diarrhea stop, so gradually returning to a varied, nutrient-rich diet supports recovery better than prolonged reliance on a few bland foods The BRAT diet (bananas, rice, applesauce, and toast) lacks enough protein, healthy fats and several key vitamins and minerals to fully support recovery, making it better as a small part of your diet than your entire eating plan Temporary bloating or difficulty digesting milk and larger servings of starch after a stomach bug often reflects a healing digestive tract, not a lifelong food intolerance, and many people regain their normal...

Long-term exercise success depends less on willpower than on choosing activities you enjoy, keeping workouts at a manageable level and creating a routine that fits naturally into your daily life Positive experiences during exercise, such as feeling energized, accomplished or connected to other people, make you far more likely to return than workouts that leave you exhausted or discouraged Building confidence starts with following through on realistic goals, tracking your progress and creating a backup plan for busy days instead of expecting every workout to be perfect Exercise habits form at different speeds for different people, so consistency over weeks...

We're wired to embrace food and to resist anything that feels like medicine — and day to day, behavior follows that feeling far more than it follows logic Nutritional supplements in food-based formats slip into meals you already eat, thereby removing most of the friction that undermines pill routines Habits tend to stick better when they're anchored to something you already do every day, and eating is about the most reliable daily anchor there is How a supplement tastes and feels strongly shapes whether people keep taking it: pleasant and easy gets taken, unpleasant gets abandoned A food-first format also rewrites th...

Sleeping fewer than seven hours per night is strongly linked to reduced long-term well-being, even when factors like diet, exercise, income, and access to health care are taken into account Large-scale U.S. data shows sleep loss predicts reduced overall well-being more reliably than many habits people focus on daily, including physical inactivity and poor dietary choices Chronic short sleep keeps your body's natural maintenance systems under greater demand, preventing the nightly repair work your body relies on to stay resilient over time Sleep pressure builds when your cells work harder to produce energy, leading to natural signals that guide...

Chronic kidney disease now affects an estimated 788 million adults worldwide, roughly one in seven adults, making it one of the largest and fastest-growing chronic health challenges on the planet Most people with kidney disease are in the early stages and often have no obvious symptoms, allowing damage to progress silently for years before it's discovered Kidney disease extends far beyond the kidneys themselves; impaired kidney function contributes to more than one in 10 cardiovascular deaths worldwide by increasing strain on the heart and blood vessels High fasting blood sugar, high blood pressure, and excess body weight were identified as leading contributors...

A study of more than 450,000 adults found that every additional 30 grams of processed meat consumed daily was associated with a 9% higher risk of gastric cancer and a 13% higher risk of esophageal adenocarcinoma People who ate the most processed meat had a 46% higher risk of gastric cancer and more than double the risk of esophageal adenocarcinoma compared to those who ate the least Research on oral cancer found that smoked, fried, roasted, and other heavily heat-treated meats were linked to greater risk, with smoked meat emerging as the strongest independent risk factor High-temperature cooking creates compounds called polycyclic aromatic hydrocarbons (PAHs...

Dental amalgam is approximately 50% mercury by weight, and it releases a vapor that can be inhaled and absorbed, with children's developing neurological systems potentially more sensitive to its effects Since 2020, the U.S. Food and Drug Administration (FDA) has advised dentists to avoid mercury fillings in children under 6 and other higher-risk patients, but the recommendation carries no obligation and no penalty for ignoring it Access to mercury-free care remains unequal, with low-income children, children of color, indigenous communities, Medicaid patients, service members, and institutionalized people often having fewer choices about the materials used Forty-six countries have banned amalgam by law...

The supplement aisle runs on a single promise — that bigger numbers are better — but past a point, "more" stops translating into more that your body actually keeps The neon-yellow urine after a big multivitamin is mostly riboflavin passing straight through; it's a daily receipt for the part you paid for and didn't absorb Absorption is dose-dependent: the fraction your body takes up tends to fall as the dose climbs, so doubling the dose doesn't double what reaches your cells With some nutrients the body actively limits how much it admits at once, so how and when you take a supplement can...

Chronic kidney disease affects 844 million people worldwide, yet women are less likely than men to be tested, diagnosed, referred to specialists, or receive treatments that have been adequately studied in female patients Up to 30% to 50% of chronic kidney disease cases go undiagnosed in high-income countries, and women are up to twice as likely as white men to remain undiagnosed even when kidney damage is present Women account for about 55% of the global chronic kidney disease population but represented only 45.4% of participants in kidney disease clinical trials, creating major gaps in knowledge about how treatments affect women Social and economic factors...

August 16 through 22, 2026, we celebrate our 16th Mercury-Free Dentistry Week. Consumers for Dental Choice has engineered a tectonic shift in dentistry — modern dentists no longer place mercury-based dental fillings (amalgam) — and aware consumers shun them Unlike a decade ago, neither the U.S. Food and Drug Administration nor the World Health Organization defends amalgam, and major dental products companies have stopped making it During the last 16 years, I have watched my friend Charlie Brown, executive director for Consumers for Dental Choice, build a powerhouse national and international force that is changing dentistry 180-degrees, from mercury-based to mercury-free In early February 2026, the U.S...

Microplastics and nanoplastics are now found in food, water, and air, and research suggests they accumulate in organs such as the liver, pancreas, kidneys, and brain. Laboratory and animal studies indicate they may contribute to oxidative stress, inflammation, and insulin resistance in these areas The same biological changes linked to microplastic exposure are also associated with Type 2 diabetes, including impaired blood sugar control, disrupted gut bacteria, and metabolic dysfunction that develops long before symptoms appear In animal studies, nanoplastics, which are microscopic, crossed the blood-brain barrier, where they triggered inflammation, interfered with how brain cells use glucose for energy, and...

The morning handful of capsules is a holdover from a slower era — nearly every other part of daily life has been simplified, but the pill routine never was The sheer number of capsules required for some nutritional supplement regimens is itself a barrier to long-term adherence Difficulty swallowing pills is far more common than most people assume, and larger pills are dramatically harder to get down — a common reason for why so many people fail to maintain their supplement routines Multiple daily schedules and travel make a pill or capsule routine fragile; it's often the first thing to fall by the...

In a small, eight-week trial, participants who drank 1 liter of hydrogen-rich water daily showed higher GLP-1 levels than those drinking plain water Participants who consumed hydrogen-rich water experienced substantially larger reductions in food cravings than those who drank regular water, which may make it easier to resist unnecessary snacking The strongest improvements occurred in physical hunger-related cravings, which may reflect an effect on the body's appetite signals rather than simple appetite suppression, though the study did not test this mechanism directly Along with supporting appetite regulation, hydrogen-rich water improved subjective sleep quality and lowered both total cholesterol and LDL cholesterol...

After heavy sweating, plain water doesn't fully replace what your body loses because sweat carries away sodium, potassium and other electrolytes that are necessary for proper hydration, muscle function and recovery In a study of firefighters recovering from extreme heat exposure, carbohydrate-electrolyte drinks restored hydration more effectively than water alone, even though all participants drank the same amount of fluid People who consumed electrolyte-containing drinks remained less thirsty, retained more fluid and cleared exercise-related lactate faster, helping their bodies recover more efficiently after strenuous activity Hydration isn't just about how much you drink; paying attention to thirst, urine color and...

More than 53 million Americans live with arthritis, yet regular physical activity is considered one of the most effective non-drug strategies for reducing pain, improving mobility, and supporting independence — without relying solely on medications You don't need intense workouts to benefit; even short bouts of walking, stretching, gardening, or other movement throughout the day help improve joint function and contribute toward recommended activity goals Strength training helps protect painful joints by building the muscles that support them, and blood flow restriction methods such as KAATSU may allow you to gain strength using much lighter weights Sitting for long periods allows joints to...

A landmark trial involving more than 8,400 heart attack survivors found that beta blockers did not reduce the risk of death, repeat heart attack, or hospitalization for heart failure in patients whose hearts maintained relatively normal pumping function Death rates, repeat heart attacks, and heart-failure admissions were nearly identical between patients who took beta blockers and those who did not, challenging a treatment practice that has been standard for nearly 40 years A follow-up analysis found that women taking beta blockers faced a 45% higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who did not receive...
