A supplement label helps identify a product, but it does not answer every question about benefit or safety. Start by checking the serving size. The amount listed for a serving may involve more than one tablet, capsule or scoop.
Look at each ingredient and its amount. Compare the label with other products you already take, since several bottles may contain the same nutrient. More products can make the total harder to see.
In the United States, supplements follow a different regulatory pathway from medicines. FDA guidance explains that it does not approve supplements for safety and effectiveness before they are marketed. A familiar-looking package should not be mistaken for a drug approval.
A claim about supporting a body function does not show that a product treats a disease. Ask for research on the exact proposed use rather than relying on a phrase on the front of the bottle.
Write down questions before shopping: why am I considering this, what outcome matters, and who will review whether it is appropriate? A clinician or pharmacist can help interpret the label in the context of your medicines and health.
Keep receipts, packaging and a record of use. If the label is unclear or the seller will not provide ingredient information, pause the purchase and look for independent advice. You should be able to understand what you would be taking.
