SiS Beta Fuel Energy Gel is a dual-source, high-carbohydrate gel for endurance athletes taking on longer sessions. Each gel supplies 40g of carbohydrate in a 1:0.8 ratio of maltodextrin to fructose, with a subtle flavour that reduces flavour fatigue and a texture that's gentle on the gut.
What's in it
- 40g carbohydrate per gel
- Maltodextrin and fructose in a 1:0.8 ratio, giving quick-release glucose energy plus fructose absorbed through a separate pathway
- Low sodium (around 15mg per gel); vegan friendly
- Flavours: Strawberry & Lime, Orange, Neutral
When to use it
- Marathons, long-course triathlon and long road or gravel rides
- Hard sessions where you aim for 80-120g of carbohydrate per hour
- Pairing with SiS Beta Fuel drink mix to reach those targets without relying on a single product
How much to take
SiS suggests 1-3 gels per hour, combined with Beta Fuel drink, to land at 80-120g of carbohydrate per hour for high-intensity efforts. Because each gel has low sodium, use electrolytes such as SiS GO Hydro separately. Increase your intake gradually in training.
