Energy Fuel is our fuel and hydration mix for training and racing between 1 and 3 hours. It combines simple and complex carbohydrates for steady energy without upsetting your stomach, electrolytes to replace what you lose in sweat, and beta-alanine to help reduce lactic acid. Energy Fuel is caffeine-free.
Energy Fuel Boost has a similar profile to Energy Fuel with an added 100 mg of caffeine per 20 oz. serving, about the same as 1 to 2 cups of strong coffee. It is designed for shorter, high-intensity efforts under 1 hour where you want extra energy and focus.
Please note: Energy Fuel Boost contains caffeine. If you are sensitive to caffeine or have had a reaction to it, choose Energy Fuel instead.
