Common questions

What does USP Verified mean on a label?

USP Verified means USP checked that the product contains what its label lists, in the amounts the label states. U.S. Pharmacopeia says: “Contains the ingredients listed on the label in the declared strength and amounts”

Does USP Verified mean the product has none of the additives we check for?

Not on its own. The seal's definition says what it covers. We check the other ingredients on the label, separately.
