During exercise, electrolytes are lost through sweating and must be replaced in order to maintain fluid balance and prevent dehydration. The SiS GO Energy + Electrolyte gel builds on the established science of the SiS GO Isotonic Energy gel, the world’s first and only truly isotonic energy gel. The gel not only delivers a rapid supply of easily digestible carbohydrates (22 grams) for energy, but also provides 118mg sodium, 9.5mg potassium and 1.5mg magnesium per gel.
