Twinlab Endurance Fuel Stamina Powder is the ultimate in pre, during and post-race nutrition, because it is powered by Beta-Alanine with a 4:1 Carb to Protein ration. Twin Lab Endurance Fuel is a serious multi-stage formula that anticipates the body's need for nutrition. Endurance Fuel has a defense complex, a fusion of antioxidants combined to protect muscles during exercise. The Endurance Blend with Beta-Alanine supports muscular endurance, power and output; a powerhouse carb blend that releases energy faster with waxy maize and glucose, sustains it with maltodextrin, and acts as an energy reservoir to help you finish strong (isomaltulose). The electrolyte blend aids proper hydration and helps you overcome heat stress. Endurance Fuel finishes with its featured Recovery Matrix, with time released whey and casein proteins at a 4:1 carb-to-protein ratio, helping to prepare muscles for faster recovery even during activity. Clinical studies indicate that Beta Alanine raises the anaerobic threshold in endurance athletes without any weight gain. It also assists power athletes to delay fatigue, combined with a host of clinically tested nutrients to enable longer performance and greater output.
