The Carbogen Low Gi Carbogen is an informed sport certified & no artificial colourants. Isomaltulose. Electrolytes. 1125mg L-GLUTAMINE. Sustained Release Energy Drink Biogen Carbogen Low GI is an advanced Carbo-loading and Intra-exercise formula. It contains the trademarked ingredient Palatinose™ (Isomaltulose), which is a source of both glucose and fructose. Palatinose™ is a LOW GI carbohydrate source – it releases energy gradually while promoting the storage of glycogen in muscle during carbo-loading, and the utilization of fat stores during training/events. Muscle glycogen is a vital energy source for the body. Biogen Carbogen Low GI is enhanced by the inclusion of antioxidants. The risk of overtraining can also be reduced by providing sufficient electrolytes, phosphates and amino acids, all of which are present in this formulation.
