Glyco-Durance™ represents the dawn of a new era in carbohydrate supplementation. Three key elements help to reduce digestive upset while increasing physical endurance and performance. Karbolyn Endurance™ is derived from non-GMO potato and rice and this natural bio-engineered high performance carbohydrate offers rapid absorption and sustained energy. Karbolyn Endurance™ uses a proprietary multi-stage enzymatic milling process to reach optimal molecular size, yielding a superior natural bio-engineered carbohydrate for quick gastric emptying that is rapidly absorbed into the bloodstream without any side-effects like stomach bloating or cramping. The second key element is a scientifically-developed electrolyte blend based on real-time absorption. The last key element is Sustalyn® which is clinically proven to stimulate glycogen production and enhance electrolyte and water absorption in the intestine by up to 27%.
