The SiS BETA Fuel + Nootropics Energy Gel is built for endurance athletes who need both high-carbohydrate fuelling and mental focus during long training sessions and races. Designed for running, cycling, triathlon, sportives, marathons and ultra-distance events, each gel delivers 40g of dual-source carbohydrate to help support sustained energy when performance demands are high.

Using SiS BETA Fuel’s advanced 1:0.8 maltodextrin-to-fructose ratio, this high-carb energy gel is designed to help athletes take on larger amounts of carbohydrate more effectively during exercise. It is especially suited to sessions and events lasting over 2 hours, where consistent fuelling is key to maintaining output and working towards higher carbohydrate targets.

What makes this gel different is its added nootropic blend, combining 250mg Cognizin® Citicoline, 1g L-Taurine, 200mg caffeine and 200mg L-Theanine to support alertness, focus and decision-making when fatigue starts to build. Available as Single Serve, Pack of 6 and Box of 30, with flavour options including Apple, Lemon & Lime and Mixed, SiS BETA Fuel + Nootropics is a serious race-day fuelling option for athletes who want to fuel both body and mind.
