NSF Certified for Sport products go above and beyond the minimum requirements of the dietary supplement industry. Each batch is tested for accuracy of ingredients and screened to ensure there are no levels of contaminants, masking agents or banned substances. It is not uncommon for high profile athletes to test positive for banned substances they accidentally consume through their supplements. That's why the NFL, MLB, NHL and PGA recommend athletes only take products that are NSF Certified for Sport.
