GU Energy Gels: ESPRESSO LOVE FlavourEspresso Love is the ideal flavor for a busy athlete. This flavor will remind you of a bold, rich, dark-roasted cup of joe - so good you might just sip on the gel like it&';s a lazy Saturday morning. Plus, with 40mg of caffeine, it&';s perfect for those early morning workouts. Love is in the name, and it&';s also in the recipe, because here at GU, one of our six core values is love. Includes 40mg caffeine.Created for daily training and competition, GU Energy Gel packs energy-dense calories in a portable packet to help sustain energy demands of any duration or activity. The 100-calorie packet contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. 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.
