USP Verification Services
USP offers verification services for dietary supplement finished products, dietary ingredients, pharmaceutical ingredients, and excipients. Products and ingredients that meet all USP verification requirements—including a GMP audit, product and ingredient testing, and manufacturing documentation review—are awarded use of the distinctive USP Verified Marks (pictured below). Participation is voluntary and available to manufacturers worldwide.
USP's verification services draw upon our experience setting federally recognized public standards of quality for medicines, dietary supplements, and foods. USP has been establishing standards since 1820, and, today our standards are used in more than 140 countries.
