How to Read a Supplement Label Before You Buy
Start with serving size
Read the serving size and servings per container before comparing amounts. The amount shown may refer to more than one capsule.
Keep comparisons consistent
A hypothetical bottle with 60 capsules and a two-capsule serving contains 30 servings. Another with 60 capsules and a one-capsule serving contains 60 servings. This is arithmetic, not a dosing recommendation.
Record what the label says
Write down ingredient names, amounts, units, and any unclear information. Do not fill gaps using the label of a different product.
Examine the claims
FDA explains that dietary supplements are not approved for safety and effectiveness before marketing. Availability for sale is not FDA approval.
Check the version
Keep the product name, label image, seller, and date. Ask the seller about any discrepancy between the advertised label and the delivered product.
