NSF Certifications

Three Certifications. One Facility.

Each certification is independently audited annually by NSF International — the global leader in public health and safety testing.

Certification 1 of 3

NSF/ANSI 455 Grade A

Highest-Tier Dietary Supplement GMP

NSF/ANSI 455 is the most comprehensive and demanding GMP standard available for dietary supplement manufacturers. Grade A represents the top tier of compliance, covering quality systems, personnel, facilities, equipment, production controls, laboratory operations, and documentation at a level far exceeding basic FDA requirements.

NSF GMP Registration (ANSI 173)

Third-Party Verified Good Manufacturing Practices

NSF GMP Registration under ANSI/NSF 173 certifies that our facility meets rigorous Good Manufacturing Practice requirements through independent auditing. This goes beyond self-declared GMP compliance by involving third-party verification of processes, documentation, and quality controls.

FAQ

Frequently Asked Questions

Questions about our certifications and compliance standards.

What is NSF/ANSI 455 Grade A?
NSF/ANSI 455 is the most rigorous Good Manufacturing Practice standard for dietary supplements in the United States. Grade A is the highest tier, requiring compliance with comprehensive quality systems that go far beyond FDA 21 CFR Part 111 requirements. Very few manufacturers achieve this level.
How is NSF different from FDA GMP?
FDA 21 CFR Part 111 sets the baseline GMP requirements. NSF certifications (ANSI 173, ANSI 455) go significantly beyond with third-party auditing, more stringent testing protocols, and continuous monitoring. NSF Certified for Sport adds banned substance testing on top.
Are your certifications current and independently audited?
Yes. All three NSF certifications are maintained through annual independent audits conducted by NSF International. Our FDA registration is current, and our facility undergoes regular inspections. We can provide current certification documentation upon request.
Why do certifications matter when choosing a manufacturer?
Certifications are the only third-party verified proof that a manufacturer follows proper quality procedures. FDA registration alone only means the facility is on the FDA's radar — it doesn't verify GMP compliance. NSF certifications prove it. Contact us to discuss your certification needs.
