What is NSF Certified for Sport®?

Thorne offers an extensive line of NSF Certified for Sport formulations that will give you peace of mind as you strive to reach new heights. This rigorous certification ensures that every batch of Thorne’s NSF Certified for Sport supplements have been third-party tested by NSF International to verify that each product contains exactly what the label claims it does, in the amounts listed, without any of the nearly 300 substances banned from competition by major athletic organizations. The NSF Certified for Sport seal helps athletes make safer decisions in their choice of supplementation and is the only independent third-party certification program recognized by MLB, NHL, and CFL
