GU is one of the best-tasting and most palatable energy gels on the market. Each GU gel provides a shot of 100 calories in the form of a patented carbohydrate blend (70-80% maltodextrin and 30-20% fructose) to deliver high-quality, easily-digested and long-lasting energy.
GU can be used by itself or with chews, blocks and bars. Taking in 40-80 grams of carbohydrate per hour of exercise keeps your energy levels high so you can go for hours and hours and still feel strong.
GU also includes electrolytes to ensure proper hydration, an antioxidant blend to stave off muscle tissue damage and an amino acid blend to delay muscle fatigue. Strawberry Banana and Lemon do not have any caffeine in them. Orange, Vanilla, Chocolate, Triberry and Plain all have 20mg of caffeine per packet. GU's Espresso Love flavor has 40mg of caffeine.
