GU's Energy Gel was created for daily training and competition. It is a portable packet full of energy-dense calories that help sustain the energy demands of any duration or activity. The packet contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help diminish stomach distress. While the primary electrolyte lost in sweat, sodium, helps to maintain water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage.
