USP & Manufacturers

USP is a nonprofit, scientific organization that sets standards of identity, quality, purity, and strength for prescription and over-the-counter medicines, dietary supplements, and food ingredients. Recognized and used in more than 140 countries, USP standards help manufacturers ensure the production of consistent quality ingredients and finished products. For almost 200 years, USP has collaborated with industry, regulators, and other experts to create its written standards and, more recently, physical Reference Standards.
