The content on Nutrition Reviews is for general information and education only. It is not medical advice and is not a substitute for diagnosis, treatment or advice from a qualified healthcare professional.
Information, not medical advice
Our reviews, scores, articles, newsletter and the videos we embed are meant to help you understand products and the research behind them. They can't take into account your health history, medications, diet or goals, and reading them doesn't create a doctor–patient or any other professional relationship with Nutrition Reviews.
Never ignore professional medical advice, or delay seeking it, because of something you read or watched on this site.
Talk to a healthcare professional first
Speak with a doctor, pharmacist or registered dietitian before starting any new supplement, especially if you:
- are pregnant, trying to become pregnant or breastfeeding
- take prescription or over-the-counter medicines (some supplements change how medicines work; vitamin K, for example, can make the blood thinner warfarin less effective)
- have a chronic health condition, such as heart, kidney or liver disease, diabetes, high blood pressure or a thyroid disorder
- have surgery or a medical procedure coming up, since some supplements can increase bleeding risk or affect your response to anesthesia
- are under 18 (most products we review are formulated for adults and shouldn't be given to children or teens without a pediatrician's advice)
- have, or have had, an eating disorder, particularly before using weight-management products
- are sensitive to caffeine or other stimulants, which are common in pre-workout and energy products
- are an athlete subject to drug testing (certification programs reduce the risk of banned substances but can't eliminate it)
How dietary supplements are regulated
In the United States, dietary supplements are regulated under the Dietary Supplement Health and Education Act of 1994 (DSHEA), which treats them differently from drugs. The FDA does not approve dietary supplements for safety or effectiveness before they're sold. Manufacturers and distributors are responsible for making sure their products are safe and properly labeled and that their claims are truthful and not misleading. The FDA can take action against adulterated or misbranded supplements after they reach the market.
That's why the label, third-party testing and the evidence behind each ingredient matter so much, and why they carry so much weight in our reviews.
Statements on this site about dietary supplements have not been evaluated by the Food and Drug Administration. The products we discuss are not intended to diagnose, treat, cure or prevent any disease.
Everyone responds differently
Research describes average effects across groups of people, and your results may differ. Our scores and reviews assess products; they don't guarantee safety or results for any individual. Formulas also change, so read the label on the product you actually buy, follow its directions and warnings, and don't take more than the recommended serving unless a healthcare professional advises you to.
If you have a side effect
If you think a supplement is causing a problem, stop taking it and contact your healthcare provider. You can also report the problem to the FDA, which uses these reports to identify unsafe products. The FDA explains how on its page about reporting a problem with a dietary supplement.
In an emergency
If you think you or someone else is having a medical emergency, call 911 immediately.
For a suspected poisoning or overdose, including a child swallowing supplements, call Poison Help at 1-800-222-1222. This free, confidential line connects you to your local poison center from anywhere in the United States. Keep all supplements out of children's reach: accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6.
