GU Energy Gels give you powerful fuel, fast. With an assortment of flavors, like Hoppy Trails and Birthday Cake, GU gels are created for everyday training and competition. Each 100-calorie packet delivers a sweet hit of carbohydrates from maltodextrin and fructose, which your body can absorb and use quickly. Alongside the carbs, GU formulated its gels with sodium to replace the primary electrolyte you lost in sweat, and added branched-chain amino acids that may reduce mental fatigue and decrease muscle damage. The combination of carbs, electrolytes and BCAAs give you well-rounded nutrition in a packable, slurpable pouch. GU crafts each Energy Gel with all vegan ingredients, and they are all gluten-free and kosher. Whether you’re powering your Sunday long run or sustaining your ultramarathon, there’s a portable GU Energy Gel that will give you the fuel you need to make it through. For optimum results, always drink at least 24-30 ounces of fluid per hour during training and racing. Exact GU intake depends on the intensity of your pursuit and your body weight and fitness level.
