Unlike traditional gels which are typically made up of water and carbohydrates simply mixed into syrups, often with added flavours and preservatives, the GEL 100 CAF 100 is completely different. It's built with seven natural ingredients and uses unique patent-pending hydrogel technology and a blend of fructose and glucose to enable uptakes of up to 100 grams of carbohydrates per hour. In addition, it also contains 100 mg of caffeine to keep a sharp focus. Widely used by the worlds best athletes, if you're serious about performance, this is THE Gel.
