Reading a supplement label

Every dietary supplement sold in the United States carries a Supplement Facts panel. Once you know the four parts of it, comparing products across brands takes a minute.

1. Serving size and servings per container

Everything else on the panel is “per serving”, so start here. Two products with the same amount of an ingredient can differ a lot if one serving is one capsule and the other is three. Divide the price by servings per container to compare cost honestly; our catalog lists container sizes in the product name where the brand provides them (for example “60 capsules” or “4 oz”).

2. The ingredient panel

Named ingredients with amounts are listed first. Amounts are in milligrams, micrograms or international units, with a percent Daily Value where one exists. A “proprietary blend” lists ingredients together with a single total amount; you cannot tell how much of each is inside.

3. “Other ingredients”

Below the line are the non-active parts: capsule material, flavors, sweeteners, flow agents. This is where you check for things you avoid, such as gelatin capsules if you are vegetarian, or specific sweeteners.

4. The disclaimer

Supplements carry the statement: “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” It is required whenever a product makes a structure/function claim (for example “supports normal sleep”). It means the product is a supplement, not a drug, and that the brand is describing support for normal function, not a medical effect. You will see the same disclaimer on every supplement page on this marketplace.

Where to find the panel for our products

Each product page links to the brand’s own site (“View on <brand>”) where the full Supplement Facts panel and lot information are published. If a label detail matters to you, check the brand page before you buy, and ask your clinician if you take medication.
