This is a tube of Gu Brew Electrolyte Tabs. The GU Brew is about electrolytes first, then carbohydrates. But carbs are key to endurance nutrition so we take them seriously. We use a 50:50 ratio of fructose (simple) and maltodextrin (complex) carbs because carbs in this combination increase the amount of energy available to muscles.
