Elite XT Extended Release protein is designed to be the ultimate muscle fuel & workout recovery formula. Dymatize determined that no single existing natural protein source was ideal for achieving extended release anabolic effects. The optimal source was found to be a fusion of several different protein sources, including the addition of free form branch chain amino acids & Milk derived proteins. Elite XT is further enhanced by the addition of Nutrateric, a revolutionary, pharmaceutically-developed coating system. This delayed release technology allows the specific material it coats to release at a particular p H range. In fact, with this coating process, the resulting digestion can take more than twice as long as other forms of non-coated protein, further enhancing the extended release capacity of Dymatize Elite XT.
