NSF/ANSI 455-2: Dietary Supplements

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

NSF International is transitioning clients from its current GMP registration (NSF/ANSI 173 Section 8) to NSF/ANSI 455 GMP certification to be able to certify facilities to a consensus-based national standard, and to allow manufacturers to reduce their annual audit burden.

We are currently accepting applications for audits for dietary supplements (NSF /ANSI 455-2), and the current dietary supplement GMP registration will be phased out entirely by 2022.

The updates to the NSF/ANSI 173 GMP registration for dietary supplements audits implemented in 2019 were the first step toward this new standard, and incorporated many of the audit requirements of NSF/ANSI 455-2. For manufacturers, the key differences between GMP registration and the NSF/ANSI 455 GMP certification are:

  • The leading GMP audits for dietary supplements, cosmetics and OTC drugs based on current Good Manufacturing Practices and current federal regulations for each scope
  • A defined audit process that determines audit duration, timeline for CAR reviews and ongoing monitoring requirements
  • A grading system based on the number and severity of non-conformances
  • Best industry practices based on retailer requirements
  • Certification recognized by the Global Retailer and Manufacturer Alliance (GRMA) made up of leading retailers, manufacturers and other stakeholders

Transition smoothly from NSF/ANSI 173 GMP registration to NSF/ANSI 455-2.
