More Information

NSF International (NSF) is proud to offer the Dietary Supplement Certification Program. In today's rapidly growing dietary supplements industry, manufacturers can now differentiate their product through NSF's independent, third-party, product evaluation services including product testing and facility inspections. NSF International began its Dietary Supplement Program at the request of industry and public health representatives.

Purpose of Certification

To offer a unique, voluntary, independent, third-party, product evaluation service to the rapidly-growing dietary supplements industry. Verification of ingredients listed on product labels, contaminant testing, auditing against Good Manufacturing Practice (GMP) principles and ongoing monitoring are the basis of the program.

Benefits of NSF Certification include:

  • Confirms that product conforms to strict NSF requirements.
  • Increased product credibility and demonstrated commitment to quality.

Cost

Fees for initial certification include annual listing, qualification audits, testing and professional services. NSF provides quotes to companies upon request.

Communication/Marketing - Quality vs. Efficacy

NSF will be certifying raw materials and finished product on the basis of identity, quantity (when on label), consistency and purity where criteria for such can be established. NSF will not be certifying efficacy. The Mark and accompanying marketing materials will be designed to make it clear to the consumer precisely what NSF is certifying.
