Science in Sport Group

International science-backed sports nutrition business for professional athletes, sports enthusiasts and the active lifestyle community.

Science in Sport Group is a leading sports nutrition business that develops, manufactures and markets innovative nutrition products for athletes and active consumers worldwide.

The Group’s core range comprises gels, powders, and bars focused on energy, hydration, recovery and strength, delivered through two highly regarded brands:

  • PhD – a premium active-nutrition brand targeting the active lifestyle community.
  • SiS (Science in Sport) – an endurance nutrition brand for elite athletes, professional sports teams, and endurance sports enthusiasts.

Founded in 1992, Science in Sport is headquartered in the United Kingdom, with production facilities in Blackburn, serving a global customer base – with approximately half of the Group’s revenue originating from outside the UK.

Science in Sport is the official endurance nutrition supplier to multiple professional teams, organisations, and national teams worldwide. SiS also supplies professional football clubs across the UK, Europe, and the USA. At the Paris Olympics 2024, athletes fuelled by SiS supplements won a combined 105 medals (including 37 Golds).

High adoption by elite athletes, driven by a strong scientific heritage and stringent testing, creates a halo effect for non-elite consumers, establishing a credible and differentiated brand story. With category-leading science and elite advocacy underpinning its broad range of supplements, the Group is well-positioned to capitalise on its market leadership in an attractive, high-growth global market.
