SPORTS NUTRITION

Protein Supplements

Protein powders can make it easier to add high-quality protein when food alone does not fit your schedule or needs. They are convenient foods, not a requirement for building strength.

SPORTS NUTRITION

Creatine Supplements

Creatine is among the best-studied sports supplements. Evidence is strongest for repeated short, high-intensity efforts such as lifting or sprinting; it is not a universal performance enhancer.

FATTY ACIDS

Omega-3 Supplements

Omega-3 supplements commonly provide EPA and DHA from fish oil, krill oil, or algae. The best choice depends on diet, health context, and the specific question you are trying to answer.

VITAMINS

Vitamin D Supplements

Vitamin D helps the body absorb calcium and supports normal bone mineralization. Whether a supplement is useful depends on diet, sun exposure, age, health, and sometimes a clinician-guided blood test.

MINERALS

Magnesium Supplements

Magnesium is an essential mineral found in many foods and also in supplements and some medicines. A supplement may help fill an identified gap, but claims about sleep, cramps, or stress need careful scrutiny.

GUT HEALTH

Probiotic Supplements

Probiotics are live microorganisms that may have health benefits in particular contexts. Products are not interchangeable: effects can depend on the strain, dose, person, and reason for use.

A better starting point

Food, health, and context come first.

Supplements can be useful in specific situations, but they are not all necessary or right for everyone. A clinician or registered dietitian can help connect the research to your health history, medications, and goals.

How we work

We show the evidence, including its limits.

Guides link to NIH, FDA, and other public health resources. We distinguish established nutrient roles from emerging or uncertain supplement claims.
