GU Energy Labs Roctane Energy Drink Mix (10-Pack Box, Lemon Lime)

Created for high-intensity and demanding activity, GU's lemon lime Roctane Energy Drink Mix packs more electrolytes and carbohydrates than GU Hydration Drink Mix. The 250-calorie serving 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 hydration by maintaining water balance. The amino acid taurine helps maintain heart contractility and improve cardiac output during long exercise sessions, while the amino acid beta-alanine helps promote formation of the intramuscular buffer carnosine. The lemon lime flavor Roctane energy drink is offered here in a box of 10 travel-friendly individual packages.
