NSF GMP Registration / Certification

Issued by NSF International

Certification

Audit Scope

Third-party audit of dietary supplement GMP compliance per NSF/ANSI 455-2 standard. Annual facility inspections.

What It Proves

Independent third-party audit confirms the facility meets NSF/ANSI 455-2 dietary supplement GMP requirements. Annual inspections with unannounced audits possible.

What It Does Not Prove

Does NOT test individual products. Does NOT mean products are safe or effective. 'NSF Certified' alone is ambiguous — could refer to GMP registration, product certification, or Certified for Sport. 'Registered' vs 'Certified' distinction matters: registration is the base level.
