The relationship between the FDA and USP

Functions of the FDA and the United States Pharmacopeia (USP):

FDA: A government regulatory agency responsible for ensuring the safety and effectiveness of food, drugs, medical devices, etc., and enforcing relevant laws and regulations.

USP: An independent scientific organization focused on developing quality standards for dietary supplements, food ingredients, drugs, etc., which are included in the United States Pharmacopeia-National Formulary (USP-NF) and the Food Chemical Code (FCC).

Relationship between FDA and USP:

In short, the FDA is a government regulatory agency and the USP is an independent organization. There is no organizational affiliation between the two agencies, but the FDA will refer to the quality standards issued by the USP, namely FCC and USP-NF, in the management of some foods, drugs, and dietary supplements.
