QUALITY COMMITMENT
Science in Sport is internationally recognised as the safest sports nutrition brand in the world. Our products are trusted by professional teams and athletes because of our commitment to testing and certification. Each finished product that leaves the factory is screened against the World Anti-Doping Agency (WADA) list for banned substances. This rigorous testing process is undertaken externally by Informed Sport.
Driven by insights from elite athletes and practitioners, our cutting-edge research programme, and an innovative, novel product development team, we relentlessly test and refine our products with athletes and consumers alike. This approach ensures we deliver the right range of products, made with the highest-quality ingredients, so you can focus on performing at your very best.
INFORMED SPORT CERTIFIED
Science in Sport is proud to be part of Informed Sport’s quality assurance program for sports nutrition products. The program certifies that all nutritional supplements and/or ingredients that bear the Informed Sport logo have been tested for banned substances by the world-class sports anti-doping laboratory, LGC.
Banned substances, including steroids, are tested to the level of 10 Nanograms per gram, and stimulants to 100 Nanograms per gram.
Every batch produced receives the recognised and respected Informed Sport certificate.
QUALITY ASSURANCE


PRODUCT & MANUFACTURING REVIEW
INFORMED Sport evaluates our raw materials and suppliers across all production and packaging sites, as well as our operational procedures, and verifies our GMP (Good Manufacturing Practices), ensuring products are consistently produced and controlled to maintain quality standards.


PRE-CERTIFICATION TESTING
A minimum of three, final product samples are tested to the level in the ng/g region against WADA's banned substance list - an essential requirement for banned substance programmes, and risk mitigation.


CERTIFICATION TESTING
After successful certification, each batch of each product is tested and registered at wetestyoutrust.com, so anyone can verify the product they purchased has been certified.
