The United States Pharmacopeia (USP) is the official authority in setting standards for all prescription and over-the-counter medicines, dietary supplements, and other healthcare products manufactured and sold in the United States. Founded in 1820, the USP is an independent not-for-profit public health organization and is committed to developing public standards to help assure good quality in medicines, healthcare delivery, dietary supplements, and related products and practices.
USP – Verified Ingredients
The USP – Verified Dietary Ingredients Program conducts testing to verify active and inactive ingredients used to manufacture dietary supplements to ensure consistent quality. These ingredients include:
- Fine chemicals
- Amino Acids
- Botanical Extracts
- Non Botanicals
USP – Verified Ingredient certification means that the ingredients used are consistent in quality; they meet label claims for strength, purity, and quality; ingredients and products are prepared in accordance with accepted manufacturing processes; and the ingredients meet requirements for acceptable limits of contamination.
USP standards are enforceable by the FDA. Testing is voluntary and is available to all interested manufacturers. A USP – Verified Ingredient certification seal is displayed on all verified products and a list of all certified products is available on www.usp.org.
USP – Verified Ingredient status is obtained through vigorous testing of the following:
- Laboratory evaluation of ingredient samples for compliance with label claims and USP program requirements
- Review of manufacturing and quality control documentation
- Audit of manufacturers quality systems for compliance with Good Manufacturing Processes
Previously verified ingredients are often re-tested to ensure continued compliance with USP requirements.
- Test active and inactive ingredients
- Quality Control Documentation Review
- Audit of manufacturing systems
- Open to all manufacturers
- Voluntary participation
- Fee paid for testing
