Medical Disclaimer

The Health Primer provides general information and education. It is not personalized medical advice, and nothing on this site should be used to diagnose, treat, cure, or prevent any disease or medical condition.

Talk to a healthcare provider

Always consult a qualified healthcare provider before starting any new supplement, exercise program, or significant change to your diet or routine — especially if you have an existing health condition, take prescription medication, or are pregnant or nursing. Individual results and needs vary, and general information cannot account for your specific medical history.

Tools and calculators

Every calculator and tool on this site produces an educational estimate based on general, publicly available reference guidance — never a personalized recommendation. Each tool’s methodology section states its assumptions, sourcing, and limitations.

Product reviews

Our product reviews and evidence ratings reflect our editorial assessment of publicly available information and research. They are not a substitute for consulting a healthcare provider about whether a specific product is appropriate for you.

Emergency situations

If you are experiencing a medical emergency, call your local emergency services number immediately. Do not rely on this website in an emergency.
