Roctane Ultra Endurance Energy Drink is a carbohydrate intensive energy drink mix formulated especially for ultra-distance and intense racing or training efforts. It contains the critical carbs and electrolyte replenishment that endurance athletes need to compete at high levels. Each serving contains 250 calories of complex and simple carbs that are optimized for rapid absorption and energy accessibility. Key electrolytes, including 320mg of sodium, help maintain hydration. Roctane Ultra Endurance Drink contains beta-alanine which supplements dietary beta-alanine to improve muscle buffering during intense efforts, and branched-chain amino acids, which are shown to serve as an additional fuel source (when taken with carbohydrates), reduce muscle damage, enhance recovery, and delay fatigue. Select flavors contain 35mg of caffeine, which increases focus and concentration, and decreases perceived effort. Roctane Drink is light tastingnot chalky like most calorie-dense drinksand mixes easily in a bottle with 21 ounces of water. One bottle per hour, supported when necessary by one Roctane Gel, is recommended for races and prolonged exercise. Available in a 1.72-pound/12-serving canister or 3.44-pound/24-serving jar.
