Our reviews, guides, scores, and articles are written to help you understand supplements. They are not a diagnosis or a treatment plan, and reading them does not create a doctor and patient relationship between you and us.

Never ignore professional medical advice, or delay getting it, because of something you read here. Never stop or change a medicine your doctor prescribed, for example for diabetes or blood pressure, because of a supplement review.

Statements about supplements on this site have not been evaluated by the US Food and Drug Administration or by the health regulator in your country. Supplements are not intended to diagnose, treat, cure, or prevent any disease.

Check with a doctor or pharmacist before you start any supplement, especially if you:

• are pregnant, planning a pregnancy, or breastfeeding
• take prescription or over-the-counter medicine, since some supplements can interact with it
• have a medical condition or an upcoming surgery
• have allergies, or are giving a supplement to a child

Read the full ingredient label before you buy. If you notice a bad reaction, stop taking the product and get medical help. In an emergency, call your local emergency number. Do not use this website for emergencies.

When we describe what a product is "marketed for", that is the company's claim, not a fact we are confirming. Our team's own experience with a product is one person's experience, and it isn't clinical proof. Results differ from person to person. See how we work on our methodology page.

Formulas, prices, and refund policies change. We update our reviews and show the date, but we can't promise that every detail is current. Check the label and the seller's page before you buy.

Some links take you to websites we don't control, and some are affiliate links (see our affiliate disclosure). We are not responsible for the content or practices of those sites.
