NSF International offers a comprehensive range of services to meet the needs of the dietary supplements industry globally. Our role is to ensure product and ingredient safety, giving both industry and consumers peace of mind through facility GMP compliance, accredited product certification programs and testing services.

Product and Ingredient Testing and Certification
The NSF Dietary Supplement Certification Program certifies dietary/nutritional supplements, ingredients and functional foods to ensure they meet the requirements of the official American National Standard for Dietary Supplements (NSF/ANSI Standard 173). The certification process includes: a toxicology and label review to verify product formulation and marketing claims, testing to identify and quantify dietary ingredients declared on the product label, testing to ensure the product does not contain unacceptable levels of contaminants, and twice annual Good Manufacturing Practices (GMP) facility inspections.

NSF Certified for Sport®
To meet the growing demands of athletes, coaches and all those concerned about athletic banned substances in sports supplements, we created the NSF Certified for Sport®​ Program. This program builds on the NSF Dietary Supplement Product Certification Program by additionally screening for approximately 300+ athletic banned substances to ensure the product is free of prohibited substances on the WADA, NFL and MLB prohibited substances lists. NSF Certified for Sport® is used by the NFL, NFLPA, MLB, MLBPA, LPGA, PGA, CPSDA, CCES and individual athletes to help ensure the supplements and sports nutrition products their athletes use are free of prohibited/banned substances.
