About USP

The United States Pharmacopeial Convention (USP) is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide. USP’s drug standards are enforceable in the United States by the Food and Drug Administration, and these standards are developed and relied upon in more than 130 countries.

USP standards are developed and revised by more than 800 volunteer experts, including international participants, who work with USP under strict conflict-of-interest rules. Since its founding in 1820, USP has helped secure the quality of the American drug supply. Building on that legacy, USP today works with scientists, practitioners, and regulators of many nations to help protect public health worldwide.
