Created for demanding training and competition, GU Roctane Energy Gel stands out from original GU Energy Gel with more sodium, an electrolyte that aids in hydration, and even more branched-chain amino acids (leucine, valine, and isoleucine) that reduce mental fatigue and decrease muscle damage than our original GU Energy Gel. The amino acid beta-alanine helps promote formation of the intramuscular buffer carnosine, while ornithine alpha-ketoglutarate helps promote muscle repair. The 100-calorie packets contain carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. What's the ROCTANE differenceIn short, ROCTANE Energy Gels are designed for long-duration and high-intensity activities, when you're trying to up your mileage or push yourself further. But what does that really meanIt means that ROCTANE Energy Gels are packed with up to three times as much sodium (depending on the flavor), and three times as many branched-chain amino acids as compared to our original Energy Gels. ROCTANE Energy Gels also have extra amino acids: Taurine can help maintain heart contractility and improve cardiac output during long exercise sessions and beta-alanine can help promote formation of the intramuscular buffer carnosine, which can help delay the onset of fatigue during high-intensity efforts.
