Roctane Ultra Endurance Energy Drink is a carbohydrate intensive energy drink for ultra-distance and intense efforts. It contains the critical carbs and electrolyte replenishment that endurance athletes need to compete at high levels. It is a super light tasting, easy to mix formula for fueling serious efforts. Each serving contains 240 calories of complex and simple carbs that is optimized for rapid absorption and energy accessibility. Key electrolytes help with hydration. Roctane Ultra Endurance Drink contains beta-alanine which supplements dietary beta-alanine to improve muscle buffering during intense efforts and branch chain amino acids, shown to serve as an additional fuel source (when taken with carbohydrates), reduce muscle damage, enhance recovery and delay fatigue. Roctane Drink mixes easily and isnt chalky like most calorie dense drinks on the market. The key ingredients in the drink are specifically designed for long and intense endeavors. For many athletes, all they may need during prolonged exercise is one 21oz bottle of Roctane Drink and 1 Roctane Gel per hour for 340 calories and extra nutritional support to maximize performance.
