What is Amplified Endurance Booster? Need an endurance boost? Go the distance and improve your time with Amplified Endurance Booster! It’s GNC’s most effective endurance product ever! This clinically studied formula is proven to improve endurance performance by 78% and make intense endurance exercise easier!*^ This unique formulation combines the nutrients your body needs the most during endurance exercise to go the extra mile. Key features include… Specialized Carbohydrate Blend – During intense long distance exercise, adequate amounts of quality carbohydrates must be available to energize your working muscles for the long haul. This formula contains two fast-acting carbs, dextrose and ribose, with a slower acting carbohydrate, maltodextrin, to provide sustained energy and blood sugar levels needed for maximum endurance performance.* 10 grams of Muscle Fueling Protein – While most sports drinks are made up simply of carbohydrates, studies show that a combination of carbs and protein during exercise can improve performance and better fuel your muscles for endurance exercise. That’s why this formula is packed with 10 grams of high quality protein to better fuel your game. Critical Amino Acids – Without a full amino acid pool, endurance performance can suffer. This product features Branched Chain Amino Acids (BCAA) to help preserve muscle glycogen stores and reduce protein breakdown during long distance activity.* It also includes glutamine, which plays an important role in muscle function and hydrating muscle cells.* 5-Electrolyte Blend – This thirst-quenching, hydration enhancer provides a 5-electrolyte blend, all of which are lost through sweat during exercise. Replacing lost electrolytes is necessary to help regulate body fluids. Not getting the right amounts of fluid, electrolytes, and other minerals present in this top notch formula may lead to muscle cramping. Vitamins and Minerals – Equipped with B-vitamins, this formula also supports carbohydrate metabolism and energy production.* Plus, it’s enhanced with calcium, which plays an important role in muscle contractions, and magnesium, which is necessary for muscle function.*
