Is My Supplement Third-Party Tested?

Search our database of 300+ supplements to see which carry NSF Certified for Sport, USP Verified, Informed Sport, or ConsumerLab certification — the four gold standards of supplement quality verification.

NSF Certified for Sport®

USP Verified®

US Pharmacopeia verification. Tests label accuracy, purity, potency, dissolution, and GMP compliance. Consumer-focused; most rigorous for ingredient amounts.

Informed Sport®

UK-based, used globally. Every batch tested for banned substances. Favoured by Olympic athletes and sports governing bodies. Strict batch-level testing.

ConsumerLab◆

Independent testing organisation. Purchases products off shelves and tests label accuracy, contaminants, and disintegration. Publishes pass/fail reports.

FAQs

Which certification is best for athletes?
NSF Certified for Sport and Informed Sport are the most recognised by professional sports leagues and anti-doping authorities (WADA, USADA). Both test specifically for substances banned in sport. NSF is preferred by North American leagues (NFL, MLB, NBA); Informed Sport is favoured by many Olympic sports and is the standard recommended by UK Anti-Doping.
What percentage of supplements are third-party tested?
Fewer than 5% of supplements sold in the US carry a recognised third-party certification. This means the vast majority of supplements on the market have not been independently verified for label accuracy, purity, or potency — they rely on manufacturer self-certification only.
