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. This patented blend uses non competing pathways to help maximize carbohydrate absorption while minimizing stomach distress.

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 a branched chain amino acid blend to encourage muscle repair. GU Energy Gel comes in both caffeinated and non-caffeinated flavors. Strawberry Banana, Lemon Lime, Peanut Butter, Birthday Cake and Root Beer do not have any caffeine in them. Mandarin Orange, Vanilla Bean, Chocolate Outrage, Triberry, Tastefully Nude, Chocolate Peanut Butter, and Salted Watermelon all have 20mg of caffeine per packet. GU’s Espresso Love, Caramel Macchiato, and Jet Blackberry flavors have 40mg of caffeine.
