SIS supply official nutrition to Team Ineos Grenadiers, the British Cycling national team, and numerous professional enduro and gravel athletes. Their products are formulated in collaboration with the University of Exeter's sport science department and tested in professional race environments before reaching retail. What Is Science in Sport and Who Uses Their Products? The SIS GO Energy Gel is their entry product — a 22g sachet delivering 22g of carbohydrates in isotonic formulation that requires no additional water to consume, unlike most gels that need to be washed down. The Beta Fuel 80 is their premium race-day gel — delivering 80g of carbohydrate per 60ml sachet using a 1:0.8 glucose-to-fructose ratio that allows absorption at rates of 80–120g per hour, far beyond what glucose alone can achieve. REGO Rapid Recovery is their post-ride recovery drink combining 23g protein with 23g carbohydrate for muscle glycogen and protein synthesis. Why Choose SIS for Cycling Nutrition?

For British cyclists, SIS also offer practical advantages: UK-based manufacturing, excellent retail availability, and
