To protect and improve their health, many people purchase dietary supplements and herbal medicines over the counter—often assuming they’re regulated like drugs. While the law requires pharmaceuticals to meet specific quality standards set by USP, the same requirements don’t apply to supplements. That’s why we’ve created quality standards and a verification process specifically for these health products, giving manufacturers the tools they need to safeguard the health of their consumers. Brands that display the USP Verified Mark signal to the public that what’s on their label is what’s in the bottle, allowing their vetted product to stand apart from a majority of the competition.
