Business in the Community

Innovation and Integrity

Science in Sport is committed to developing the world’s most innovative performance nutrition products, enabling our customers to achieve their performance-driven goals.

Our sports nutrition experts work closely with elite athletes, such as Sir Chris Hoy and Adam Peaty, to extend and improve our extensive range of nutrition products.

The PhD and SiS ranges are trusted by professional and Olympic athletes and fitness enthusiasts across the world. A key component of this trust is our approach to preventing banned substances entering our supply chain and finished products. We work closely with the world’s leading sports federations and anti-doping agencies, and rigorously and routinely test our products and premises for quality and adherence to the strictest anti-doping criteria.

This standard of testing is carried out by a very small proportion of the sports nutrition industry and no other brand globally holds both the Informed Sport Site Certification and Informed Sport Product Certification.
