Pharmaceutical science expertise, of our staff and world-wide volunteer experts, is the foundation of USP’s work to help advance public health and ensure the quality and safety of medicines, dietary supplements and foods.

The quality standards we develop help manufacturers deliver safe products to billions of people worldwide. The United States Pharmacopeia–National Formulary (USP–NF) includes over 6,800 of those quality standards for medicines, both chemical and biologic; active pharmaceutical ingredients; and excipients (inactive ingredients). It is the most comprehensive source in the world for quality standards and is utilized in over 150 countries worldwide and integrated into the laws of more than 40 countries, including in the U.S.
