Evidence-informed overviews of key supplements, from magnesium and creatine to omega-3s, CoQ10, and antioxidants, through the lens of aging and cellular health.
Collagen supplements may produce modest benefits for selected skin or joint outcomes, but study quality varies and collagen is not a complete protein strategy for healthy aging.
NAD biology is compelling, and precursor supplements show biochemical activity. The unresolved question is whether changing a biomarker produces meaningful, durable health benefits.
Longevity marketing often compresses cell studies, animal experiments, biomarker changes, and human outcomes into one story. An evidence hierarchy helps separate them.
The first question about a supplement is not whether an ingredient is promising. It is whether the bottle reliably contains what the label says it contains.
A sophisticated ingredient list cannot compensate for inaccurate potency or contamination. Supplement quality starts with identity, manufacturing, testing, and transparency.
Vitamin B12 is essential for blood cells and the nervous system, but more is not always better. Risk factors, symptoms, and lab context should guide supplementation.
Magnesium products are marketed for sleep, stress, muscle, glucose, blood pressure, and longevity. The mineral is essential, but an essential nutrient is not automatically an effective treatment for every goal.
"Take omega-3s" sounds simple until the label, dose, food pattern, triglycerides, cardiovascular history, and product category are considered.
Vitamin D has a strong biological role and an even stronger reputation online. Updated guidance offers a more selective approach to testing and supplementation.
Creatine is not a longevity drug, but it is one of the better-studied sports supplements and is increasingly researched for healthy aging. Its strongest role remains supporting training; cognitive findings are promising but less settled.
From collagen peptides and BPC-157 capsules to injectable growth hormone secretagogues, the peptide supplement landscape spans a wide spectrum of evidence quality. Here is how to tell them apart.
Glutathione is the body's master antioxidant. N-acetyl cysteine (NAC) is its most accessible precursor. Their biology is relevant to aging, detoxification, mitochondrial health, immune function, and the management of oxidative stress.
Coenzyme Q10 is essential for mitochondrial energy production and serves as a key antioxidant within cells. Its levels decline with age and are reduced by common medications, making it a meaningful consideration in longevity-focused supplementation.
EPA and DHA from marine sources are among the most extensively studied dietary supplements in longevity research, with consistent evidence for cardiovascular, inflammatory, cognitive, and cellular aging effects.
Creatine is the most researched performance supplement in history. But its biology of benefit extends well beyond athletic performance, to muscle mass preservation, cognitive support, and metabolic function in aging adults.
Magnesium participates in over 300 enzymatic reactions, yet inadequate intake is widespread. Its roles in energy production, sleep, stress response, inflammation, and metabolic health make it one of the most consequential gaps in modern nutrition.
