About NSF Certified for Sport®

Not all supplements are created equal. NSF Certified for Sport® products have undergone independent, third-party testing by NSF International, one of the most rigorous certification bodies in the world, to verify exactly what's on the label is what's in the bottle, and nothing more.

Every product in this collection has been tested for over 270 substances banned by major athletic organizations including WADA, NFL, MLB, NBA, PGA, and NCAA. That means no undisclosed ingredients, no harmful contaminants, and no banned substances, giving athletes and health-conscious consumers the confidence to perform and recover without compromise.

Unlike self-certified or GMP-only supplements, NSF Certified for Sport® requires annual facility audits, ongoing product testing, and strict label accuracy verification. It's the gold standard trusted by professional sports leagues and elite athletes worldwide.

Shop our full range of NSF Certified for Sport® vitamins, minerals, proteins, and performance supplements, all independently verified for purity, potency, and safety.
