Our new 15-Serving GU Energy Gel deliver the same proven ingredients as our single-serve packets. Each serving contains 100 calories from a finely tuned ratio of complex (maltodextrin) and simple (fructose) CARBOHYDRATES that deliver energy through non-competing pathway to increase utilization and prevent bonking by sparing muscle glycogen reserves. ELECTROLYTES (sodium and potassium) maintain water balance and aid in optimum hydration. AMINO ACIDS are the building blocks of protein and are crucial to performance because of a range of benefits including: reduced mental fatigue, faster muscle repair and recovery, reduced soreness and muscle fatigue, and improved function of your immune system. Some flavors also include CAFFEINE which can enhance performance by increasing focus and concentration and decreasing perceived effort. Consume one serving of GU Energy Gel or GU Roctane Energy Gel 5 minutes before and every 45 minutes during activity. Wash down with your favorite GU Hydration Drink or water for optimum absorption.
