ROCTANE Energy Drink Mix is an all-in-one solution to energy and hydration with key nutrients like electrolytes and branched-chain amino acids to keep you feeling strong and energized. The precise blend of complex and simple carbohydrates will fuel you up, so you feel good, longer. Drink one serving every hour to stay energized and hydrated while exercising.It is a light tasting, easy-to-mix formula for fueling serious efforts. Each 250-calorie serving contains:

  • Carbohydrates (maltodextrin and fructose) that use non-competing pathways which can help maximize absorption, increase carbohydrate utilization, and diminish stomach distress, so you get energy that kicks in quickly and stays with you
  • Sodium, the primary electrolyte lost in sweat that aids in hydration by maintaining fluid balance
  • Branched-chain amino acids (L-Leucine, L-Valine, and L-Isoleucine) which may reduce mental fatigue and decrease muscle damage while jump-starting recovery
  • Taurine can help maintain heart contractility and improve cardiac output during long exercise sessions†
  • Beta-alanine can help promote formation of the intramuscular buffer carnosine, which can help delay the onset of fatigue during high-intensity efforts.†

Several studies have shown that during prolonged exercise (half Ironman and Ironman events), the ability of the heart to pump blood (myocardial contractility) is decreased, which can lead to decreased exercise capacity. Similarly, prolonged exercise also promotes skeletal muscle fatigue. Taurine helps to maintain heart and muscle function by helping with calcium handling and may help decrease fatigue in these tissues during prolonged exercise. Additionally, taurine has been shown to increase muscle function with aging, and when combined with caffeine increases performance during a 1-hour cycling time trial.
