List the medicines and supplements you take
Some supplements change how medicines are absorbed or processed. Bring the labels for everything you take, including over-the-counter medicines.
Do not replace a prescribed medicine with a supplement because of something you read in an article or advertisement.
- Could this supplement interact with another medicine?
- Do several products contain the same ingredient?
- Does your health history give you a reason to avoid it?

Pregnancy, breastfeeding, surgery and children
Talk with your doctor or pharmacist about supplements during pregnancy or breastfeeding, before surgery, and before giving a product to a child.
Safety research is limited for many supplements in children and during pregnancy or breastfeeding. What is written for adults does not settle the question for a child.

FDA does not approve supplements before sale
FDA does not approve supplements for safety and effectiveness before they go on sale. A product being available to buy is not proof that it is safe for you.
