NSF Certified for Sport®

NSF logo

NSF International’s Certified for Sport® program tests and certifies nutritional supplements used by athletes in Major League Baseball (MLB), the National Football League (NFL), the Professional Golf Association (PGA), the Ladies Professional Golf Association (LPGA) and the Canadian Centre for Ethics in Sport (CCES). The NSF Certified for Sport® mark on products helps athletes of all levels buy supplements with confidence.

Certified supplements must meet rigorous standards that include comprehensive lab testing and extensive evaluation of the manufacturing process to ensure products meet their label claims and contain no harmful levels of contaminants.  These requirements are in accordance with the NSF American National Standard for Dietary Supplements (NSF/ANSI 173). NSF’s Certified for Sport® Program builds on this standard through additional screening for prohibited substances on the World Anti-Doping Agency (WADA), NSF Annex B, NFL and MLB prohibited substance lists.

The NSFSport.com website

Sports nutrition products that meet all of NSF’s criteria are then certified by NSF and appear on NSFsport.com; a multilingual resource (in English, Spanish and Chinese) for athletes to easily see what supplements are safe for consumption. Each product is listed by brand name with key product information, and the company sales contact and logo are prominently featured. In addition to highlighting NSF certified products, NSFsport.com contains performance training tips, lists prohibited substances and features a Dietary Supplement Fact Kit with information on how to understand product labels and claims. Twitter updates (twitter.com/HS_NSF) on recent news stories on doping in sports and other timely events also are available at NSFsport.com.

“News stories on steroid use in sports underscore the need for more screening of dietary supplements and sports nutrition products for banned substances. NSFsport.com helps sports dietitians, athletes and coaches identify NSF certified products that have been tested for steroids and other prohibited substances so they can be confident that the products they purchase will not result in accidental doping,” said Lisa Thomas, General Manager of NSF International’s Dietary Supplement Certification Programs.

NSF developed the only U.S. national standard for dietary supplements

NSF International developed the American National Standard for Dietary Supplements (NSF/ANSI Standard 173). The standard, which is the only U.S. national standard for dietary supplements, was developed with participation from a balanced stakeholder group, including the U.S. Food and Drug administration (FDA), National Institutes of Health (NIH), other federal agencies, state regulatory agencies, manufacturers, product retailers, industry trade associations and consumer groups. Working in concert with sports organizations, anti-doping agencies and supplement manufacturers, NSF evaluates dietary/nutritional supplements and functional ingredients to ensure they meet the requirements of NSF/ANSI 173 standard.
