GU Energy Chews are tasty gummies that pack energy-dense calories in a portable pocket to help you sustain energy to run long distances. The 90-calorie packet delivers the nutrition you need to keep running in chewable, bite-size pieces. Here is what you get from each chew: Carbohydrates that deliver ready-to-use energy and delay bonking by sparing glycogen stores. Sodium, the primary electrolyte lost in sweat, helps with hydration by maintaining fluid balance. Branched-chain amino acids (L-Leucine, L-Valine, and L-Isoleucine) that may reduce mental fatigue and decrease muscle damage while jump-starting recovery. Some flavors (such as strawberry) contain caffeine that enhances performance by increasing focus and concentration while decreasing perceived effort during exercise. Gu recommends consuming one packet 5 minutes before activity and one packet every 45 minutes during activity. Wash your delicious Gu Energy Chews down with your favorite GU Hydration Drink or water for optimum absorption.
