Maurten's Gel 100 Caf encapsulates energy in a natural hydrogel, built from seven ingredients with no added colorants, preservatives or flavors, and suitable for vegetarians and vegans. Each 40g serving carries 100mg of caffeine, roughly equivalent to one and a half espressos or a cup of brewed coffee, and delivers 25g of carbohydrate through a fructose-to-glucose blend at a 0.8:1 ratio for a high weight-to-energy ratio. It works well on its own for shorter efforts, or alongside other Maurten products to cover carbohydrate needs on longer ones. Box of 12.
