NSF/ANSI 455-2: Dietary Supplements GMP Certification

February 22, 2024

NSF offers audits and certification for dietary supplement products under the NSF/ANSI 455-2 Good Manufacturing Practices (GMP) standard.

NSF facilitated the NSF/ANSI 455-2 GMP audit standard with industry representatives, public health officials, regulators and consumer interest groups to promote safer dietary supplement products for consumers worldwide.

The standard is designed to strengthen safety, quality and trust throughout the supply chain and encompass regulatory requirements, retailer quality requirements, as well as industry best practices. Certification to the standard serves as a communication tool between manufacturers, regulators, retailers, and consumers.

Once certified, brands will receive an NSF certificate with the globally accepted ANSI logo, use the NSF/ANSI 455 GMP certification mark according to policy and appear on the NSF Product and Services Listings for Dietary Supplement GMPs . Certified clients will also have access to a dedicated 455 GMP certification co-marketing portal that contains certification marks and assets to help promote their certification.

The benefits of NSF/ANSI 455-2 GMP certification include:

Increases protection of your brand and minimizes risks
Prepares your facility for regulatory inspections
Helps your facility to build a strong quality and GMP program
Reduces the number of GMP audits and the financial costs associated with audits
