Who is United States Pharmacopeia?


The United States Pharmacopeia (USP) is a scientific, nonprofit organization that sets federally recognized public standards of quality for medicines, dietary supplements, and foods. USP has been establishing standards since 1820, and today USP standards are used by manufacturers and regulators in more than 140 countries. While others may provide testing and quality seals, USP is the only standards-setting organization recognized in U.S. federal law that offers third-party verification.

Only those products that meet USP’s stringent criteria are permitted to display the USP Verified Mark on their label. The USP Verified Mark on Nature Made products tells you that they have been independently verified for quality and:

Contain the ingredients listed on the label, in the declared potency and amounts;
Do not contain harmful levels of specified contaminants;
Will break down and release into the body within a specified amount of time; and
Have been made according to FDA current Good Manufacturing Practices using sanitary and well-controlled procedures.

Nature Made was the first national vitamin brand to earn USP Verification on many of its products and is the national vitamin brand with the most products carrying the USP Dietary Supplement Verified Mark. Many Nature Made products currently hold the USP Verified Mark, and we are committed to increasing the number of products reviewed and verified by USP in the future.
