USP Verified Mark

USP Verified MarkThe distinctive USP Verified Mark is awarded by USP to dietary supplement products that successfully undergo and meet the stringent requirements of its voluntary USP Dietary Supplement Verification Process.

Seeing the USP Verified Mark on a dietary supplement label indicates that the product:

  • Contains the ingredients listed on the label, in the declared potency and amounts
    Tests have shown that contents of some supplements don't match the label and some contain significantly less or more than the claimed amount of key ingredients. USP Dietary Supplement Verification helps assure customers that they are getting the value they expect from a product they are purchasing.
  • Does not contain harmful levels of specified contaminants
    Some supplements have been shown to contain harmful levels of certain heavy metals (e.g., lead and mercury), microbes, pesticides, or other contaminants. At specific levels these contaminants can pose serious risks to one's health.
  • Will break down and release into the body within a specified amount of time
    If a supplement does not break down properly to allow its ingredients to be available for absorption in the body, the consumer will not get the full benefit of its contents. USP Dietary Supplement Verification tests products against federally-recognized dissolution standards.
  • Has been made according to FDA current Good Manufacturing Practices using sanitary and well-controlled procedures
    Assurance of safe, sanitary, well-controlled, and well-documented manufacturing and monitoring processes indicates that a supplement manufacturer is quality-conscious, and that the supplement will be manufactured with consistent quality from batch to batch.
