NSF GMP for Sport Registration
Issued by NSF International
CertificationAudit Scope
Facility-level GMP registration under the NSF Certified for Sport program (NSF 306 — NSF's own protocol designation per the official registry; not an ANSI-designated standard, unlike NSF/ANSI 455-2): third-party audit of the manufacturing facility's GMP compliance plus banned-substance controls. Does not test individual products.
What It Proves
The manufacturing FACILITY holds NSF's GMP-for-Sport registration (NSF 306): audited GMP compliance with banned-substance control procedures, listed in NSF's GMP facility directory.
What It Does Not Prove
Does NOT mean any product is NSF Certified for Sport — product-level certification (banned-substance lot testing, label verification at nsfsport.com) is a separate program. A facility registration cannot be cited as evidence for product-level Certified for Sport claims.
