Good Manufacturing Practices (GMPs) are guidelines that provide a system of processes, procedures and documentation to assure a product has the identity, strength, composition, quality and purity that appear on its label. These GMP requirements are listed in Section 8 of NSF/ANSI 173 which is the only American National Standard in the dietary supplement industry developed in accordance with the FDA’s 21 CFR part 111.
NSF International independently registers manufacturers as meeting GMP requirements. The program is open not just to manufacturers of dietary supplements but also to manufacturers of ingredients and raw materials, as well as distribution, warehousing and packaging companies, who want to demonstrate their commitment to public safety.
