Created for daily training and competition, GU Energy Chews pack energy-dense calories in a portable packet to help sustain energy demands of long duration activities. The 180-calorie packet contains carbohydrates to keep you fueled while delaying bonking by sparing your glycogen stores. Sodium, the primary electrolyte lost in sweat, aids in hydration by maintaining water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage. ELECTROLYTES Maintain water balance and aid in optimum hydration. CARBOHYDRATES Deliver ready-to-use energy and delay bonking by sparing glycogen. AMINO ACIDS Reduce mental fatigue and decrease muscle damage. CAFFEINE Enhances performance by increasing focus and concentration and decreasing perceived effort during exercise. Consume one packet 5 minutes before, and one packet every 45 minutes during activity. Wash down with your favourite GU Hydration Drink or water for optimum absorption.
