Unived Rrunn Pre Instant & Sustained Energy is the instant and sustained energy source that you need at the beginning stages of your sports activity. Developed to avoid spiking and dropping, it is a blend of Dextrose, a simple, 100 GI carbohydrate and Isomaltulose, a complex, 32 GI Carbohydrate. It breaks down quickly and is rapidly absorbed by the body to give you an instant burst of energy. Isomaltulose breaks down slowly to release gradual, prolonged energy that lasts for up to 120 minutes of your activity. Rrunn Pre is vegan, natural, gluten-free and can be pre-mixed before an event, once you surge ahead, you stay on top without dropping.
