Nitric oxide plays an important role in blood vessel health, circulation, blood pressure, and exercise performance. Beetroot and nitrate-rich vegetables may help support nitric oxide production, but the strongest approach is still food-first: leafy greens, beets, exercise, and overall cardiovascular prevention before relying on supplements.

Fluoride can help prevent cavities, but total exposure matters — especially for young children. This article reviews the benefits of community water fluoridation, fluoride toothpaste, and dental treatments, while also discussing concerns about excessive exposure, dental fluorosis, thyroid and bone effects, and ongoing research on neurodevelopment.

Gardening is more than a hobby — it is a lifestyle habit that supports movement, nutrition, stress reduction, sunlight exposure, mental health, and connection to nature. Research suggests gardening is associated with lower mortality and better cardiovascular, metabolic, and emotional well-being, making it a powerful example of lifestyle medicine in action.

Sea moss has become a popular wellness supplement for gut health, thyroid support, immunity, and longevity. While it contains minerals, iodine, and promising bioactive compounds, strong human evidence is limited — and excessive iodine intake, thyroid effects, heavy metals, and product quality are important concerns.

Glutathione is one of the body’s most important antioxidant and detoxification molecules, supporting cellular repair, immune function, and mitochondrial health. While glutathione levels decline with age, current evidence does not show that supplementation extends lifespan — making diet, exercise, sleep, and metabolic health the foundation.

Soy is often criticized for its potential effects on hormones, but the evidence is far more reassuring than the hype suggests. Whole soy foods like tofu, tempeh, edamame, and unsweetened soy milk can be part of a healthy, longevity-focused diet, while high-dose soy supplements and ultra-processed soy products deserve more caution.

Akkermansia muciniphila is one of the newest “hot” gut health supplements, promoted for metabolism, inflammation, gut barrier support, and bloating. Early research is promising, especially for metabolic health, but human evidence remains limited — and it is not yet a valid treatment for chronic bloating.

Bluetooth earbuds produce very low levels of non-ionizing electromagnetic exposure, and current evidence does not show a clear cancer risk. The bigger health concerns are hearing loss from loud volume, prolonged use, ear irritation, wax buildup, and proper ear hygiene.

Mycotoxins are toxic compounds produced by certain molds that can contaminate foods like grains, nuts, coffee, dried fruit, and spices. Learn how they may affect health, why testing is complicated, and the practical steps you can take to reduce exposure without unnecessary fear.

Red meat remains one of the most debated foods in longevity nutrition. Processed meat is consistently linked to higher chronic disease risk, while unprocessed red meat is more nuanced. Here’s how to think about red meat, protein quality, food processing, and long-term health.

Cigarette smoking rates continue to decline, but vaping and other nicotine products are becoming increasingly common. While e-cigarettes may be less harmful than traditional cigarettes, emerging research shows they are far from harmless. Learn what the latest evidence reveals about smoking, vaping, secondhand smoke, and long-term health risks.

Parabens are preservatives commonly found in cosmetics, personal care products, medications, and some foods. While research suggests they can act as weak endocrine disruptors, the real-world health risks remain debated. Learn what parabens are, where they're found, and whether avoiding them is worth the effort.

Hyperbaric oxygen therapy dramatically increases oxygen delivery to tissues and has proven benefits for conditions such as carbon monoxide poisoning, radiation injury, and difficult-to-heal wounds. But does it improve longevity, cognition, or healthy aging in otherwise healthy adults? Here's what the current evidence actually shows.

Whey protein is one of the most studied nutritional supplements available. Research suggests it may support muscle growth, exercise recovery, weight management, cardiometabolic health, healthy aging, and even gut microbiome diversity. Learn how whey protein works and who may benefit most from supplementation.

Not all magnesium supplements are the same. Learn the differences between magnesium glycinate, citrate, oxide, L-threonate, and other formulations—including their absorption, side effects, and potential benefits.

Grounding, or “earthing,” has gained popularity for claims involving inflammation, sleep, and chronic disease. Here’s what the current evidence actually shows.

Chemical sunscreen ingredients such as oxybenzone and octocrylene are absorbed into the bloodstream and have raised questions about endocrine and long-term safety. Here’s why I personally choose mineral sunscreens instead.

Sulforaphane, a compound found in broccoli sprouts and other cruciferous vegetables, may support antioxidant defenses, metabolic health, and cancer prevention through activation of the Nrf2 pathway. Here’s what the research shows.

Reverse osmosis (RO) systems are highly effective at removing contaminants like PFAS, heavy metals, and microorganisms, but they also remove beneficial minerals and fluoride. Here’s what the evidence says about the benefits and potential downsides.

Radiation exposure from sunlight, medical imaging, and radon is part of everyday life. Learn the health risks, how exposure accumulates over time, and practical ways to reduce unnecessary risk.
