SiS GO Energy + Electrolyte Gels combine carbohydrate fuelling with added electrolytes in a compact 60ml sachet. Each gel supplies 22g of carbohydrate, making it a practical choice for runners, cyclists and triathletes preparing for longer sessions or competition.

The isotonic texture is designed to be taken straight from the sachet without an extra drink immediately alongside it. With sodium, potassium and magnesium added to the formula, these gels offer a convenient way to include both carbohydrate and electrolytes in a wider training or race nutrition plan.
