USP Verified Mark
Issued by United States Pharmacopeia (USP)
CertificationAudit Scope
Product-level verification: ingredient identity and potency, contaminant screening (heavy metals, microbes, pesticides), manufacturing practices, label accuracy.
What It Proves
Specific products have passed USP's rigorous testing program for identity, potency, purity, and manufacturing practices. One of the highest standards in the supplement industry.
What It Does Not Prove
USP Verified is product-specific, NOT facility-wide. A company may have one USP Verified product while the rest of its line is not verified. Does NOT evaluate efficacy or health claims. The USP Verified mark must be renewed annually.
