The SiS GO Isotonic Energy Gel was the world's first isotonic gel. It supplies fast, reliable energy that matches your stomach's natural fluid balance, so you can take it without water. Each 60ml gel delivers 22g of carbohydrate in a simple, mild-flavoured formula.
What's in it
- 22g carbohydrate (about 87 kcal) per 60ml gel
- Single-source maltodextrin, a glucose polymer; no fructose, so it's a simple and gentle option
- Mild natural flavours with no artificial colours; vegan; produced in an Informed Sport accredited facility
- Flavours: Apple, Blackcurrant, Tropical, Lemon & Lime, Orange
When to use it
- Runs and rides of 60-120 minutes where you need steady energy but don't want to carry or drink lots of fluid
- Races with limited aid stations, or races where handling water is awkward
- Athletes with sensitive stomachs who prefer single-source carbohydrate
- A pickup in the final kilometres of a race or a hard session
How much to take
SiS suggests 1-3 gels per hour, which gives roughly 22-66g of carbohydrate per hour. For efforts requiring higher intakes, step up to Beta Fuel, which uses a dual-source blend.
