Healthamu publishes general information about dietary supplements to help readers make careful buying decisions. Nothing on this site is medical advice, and reading it does not create any kind of patient or provider relationship.

Check with a professional before you start
Talk to your doctor or pharmacist before taking any supplement, especially if you:
- Take prescription or over-the-counter medicines.
- Are pregnant, trying to become pregnant or breastfeeding.
- Have a long-term condition such as diabetes, heart disease, kidney or liver disease, or a thyroid condition.
- Have surgery coming up.
- Are buying for someone under 18.
Do not stop, delay or change a prescribed treatment because of something you read here.
How supplements are regulated
In the US, the FDA does not approve dietary supplements for safety or effectiveness before they are sold. Makers are responsible for their own products and claims. Statements on a supplement label or ad have usually not been evaluated by the FDA. You can read more on the FDA dietary supplements page and the NIH Office of Dietary Supplements.
Research has limits
Our evidence grades describe the research on individual ingredients, not on the finished product. Study results are averages and may not apply to you. Research also changes over time, and a review can fall behind newer findings.
Emergencies
If you think you are having a medical emergency or a serious reaction, call 911 right away. For a possible poisoning or overdose, call Poison Control at 1-800-222-1222.
Report a bad reaction
If a supplement causes a side effect, stop taking it, contact your doctor, and consider reporting it to the FDA through MedWatch. Reports help the FDA spot unsafe products.
