Description

With no need for additional water, GO Energy + Electrolyte Gels are a convenient and efficient way to support your body mid-session.

Each gel contains 87 calories from easily digestible carbohydrates, helping to maintain energy levels and delay fatigue. More than just fuel, it also delivers added sodium and potassium, two key electrolytes lost through sweat, to help maintain muscle function and fluid balance. This dual-action support makes it a smart choice for athletes who need more than just carbs on the go.

The isotonic formula means the gel is absorbed quickly without the need for extra fluids, which is especially beneficial when drinking opportunities are limited. Whether you’re running a marathon, riding a sportive, or tackling a tough training session, this gel supports both performance and hydration when it matters most.

Developed by SiS with athletes in mind, the GO Energy + Electrolyte Gel is easy to use, naturally flavoured, and gentle on the stomach. It’s a go-to option for anyone seeking to maintain consistent performance while preventing the dips in energy and hydration that can derail a session.

How does it work

The GO Energy + Electrolyte Gel combines fast-release carbohydrates with electrolytes in an isotonic formulation. This ensures rapid absorption without the need to drink water, allowing energy and hydration support to be delivered precisely when it’s needed most. The carbs provide immediate fuel to working muscles, while the added sodium and potassium help replace what's lost in sweat, supporting normal muscle function and hydration.

By maintaining this balance, the gel helps delay fatigue, reduce the risk of cramping, and improve overall endurance performance. It’s an all-in-one solution for athletes pushing through challenging sessions where both energy and hydration are essential.
