Health Supplement Lab publishes research notes about dietary supplements. Those notes are general information. They are not medical advice, and they do not replace a visit with a qualified health professional.

No medical advice
Nothing on this site is meant to diagnose, treat, cure or prevent any disease. Our reviews describe labels, published research, prices and refund terms. They do not tell you what is right for your body.
Who writes our content
Our reviews are written by Ellis Warren, Lead Reviewer. Ellis is a researcher and editor. Ellis is not a doctor, nurse, pharmacist or dietitian. Our content has not been reviewed by a medical professional unless a page says so.
We do not test products
We do not run lab tests, and we do not take or buy products to try them. We cannot confirm what is inside any bottle. Our notes reflect what labels, studies and public records say. Learn more on our how we review page.
Talk to a professional first
Speak with your doctor or pharmacist before you start any supplement. This matters most if you:
- Take prescription or over the counter medicine.
- Are pregnant, trying to get pregnant or breastfeeding.
- Have a long term health condition, such as diabetes, heart disease or kidney disease.
- Have surgery planned.
- Are buying for a child or a teen.
Some supplements interact with medicines. Some can change blood sugar, blood pressure or how your blood clots.
FDA status of supplements
In the United States, the FDA does not approve dietary supplements for safety or effectiveness before they are sold. Statements on supplement labels have not been evaluated by the FDA. A product being on sale does not mean it works or that it is safe for you.
Results vary
Research findings describe groups of people under study conditions. Your own result may differ. Never stop or change a prescribed treatment because of something you read here.
In an emergency
If you think you are having a medical emergency, call 911 or your local emergency number right away. If you think you have had a bad reaction to a supplement, stop taking it and contact a health professional. You can also report the reaction to the FDA through MedWatch.
