Product and Ingredient Certification
NSF/ANSI 173 Certification
NSF certifies to NSF/ANSI 173, the only American National Standard for testing and certifying dietary supplements. Our expert team of chemists, microbiologists and toxicologists works in testing laboratories in the U.S., Europe and China.
We evaluate the composition of dietary supplements, ingredients and personal care products, including vitamins, minerals, herbs, botanicals, amino acids, sports supplements, concentrates, metabolites, constituents and extracts.
Unlike other supplement certification programs, we conduct annual audits and periodically retest each dietary supplement product to ensure continued compliance with the most rigorous testing standard in the world.
Certified for Sport®
Our Certified for Sport® program certifies dietary supplements to be free from substances banned by major sporting organizations and helps athletes, dietitians, coaches and consumers make more informed decisions when choosing sports supplements.
Certified for Sport® is the only independent, third-party certification program recognized by the United States Anti-Doping Agency (USADA), Major League Baseball, the National Hockey League and the Canadian Football League.
Certified for Sport® is also recommended by the NFL, NBA, PGA, LPGA, CCES, CPSDA, iNADO, Ironman, NASCAR, Taylor Hooton Foundation and other organizations that seek to mitigate the risks of contaminated dietary supplements.
Verify the identity and quantity of dietary ingredients declared on your product label. Our team of experts evaluates product labels or material specifications, selects and performs tests and assures your ingredients meet the necessary safety and quality requirements.
Private Label Certification
Leverage your NSF products to attract new customers and nurture existing business relationships by offering the NSF Contents Certified mark for product labels.
In addition to prequalifying your company for new business opportunities, certification ensures that all ingredients are processed to FDA’s 21 CFR Part 111 and all products are produced in a GMP-compliant facility. You'll lower your costs by decreasing the number of customer audits conducted at your facility, making your manufacturing team safer and more efficient.
