New 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.
GU Brew is naturally flavored with an ultralight taste profile for great drinkability prized by hardworking athletes.
