The mark represents that USP has rigorously tested and verified the supplement to assure the following:
- What's on the label is in fact in the bottle.
- The supplement does not contain harmful levels of contaminants.
- The supplement will break down and release ingredients in the body.
- The supplement has been made under good manufacturing practices.
USP is an independent, not-for-profit organization. No other organization in the U.S. that tests supplements is recognized in federal law as the nation's official standard-setting body for medicines and supplements. USP standards are enforceable by the FDA.
