Key Benefits
-
Fast-acting carbohydrate energy
Each gel provides 22g of easily digestible carbohydrates, helping to maintain energy levels during prolonged endurance exercise. -
Supports hydration during exercise
Added sodium, potassium, and magnesium help maintain fluid balance and replace electrolytes lost through sweat. -
Isotonic formula for easy consumption
Built on the science of the SiS GO Isotonic Energy Gel, the liquid format is designed for rapid absorption and can be taken without water. -
Convenient on-the-go fuelling
The portable gel format allows athletes to easily fuel during running, cycling, or endurance events. -
Designed for long or warm training sessions
The combination of carbohydrates and electrolytes helps support fuelling and hydration needs when sweat and energy demands increase. -

Energy and Hydration for Endurance Performance
During long training sessions or events, both carbohydrate stores and electrolyte levels can decline, which may contribute to fatigue. SiS GO Energy + Electrolyte Gel combines fast-acting carbohydrates with key electrolytes to help support energy supply and hydration during endurance exercise. This makes it a practical fuelling option for athletes completing extended or high-intensity training.
