Good manufacturing practices (GMPs) are rules 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 supplies are listed in Section 8 of NSF/ANSI 173 which is the only accredited American National Standard in the dietary supplement industry developed in accordance with the FDA’s 21 CFR part 111. NSF International’s GMP Registration Program enables manufacturers to become independently registered by NSF to meet GMP necessities. 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.
