Elite XT Extended Release Protein is designed to be the ultimate muscle fuel and workout recovery formula. Knowing that protein repairs muscle after the workout and fuels the body throughout the day, Dymatize wanted to develop a product that took recovery to the next level, one that would revolutionize the protein category. Elite XT features Nutrateric, a pharmaceutically developed coating system, is utilized on some of the ingredients to help provide an extended release of protein over a longer, extended period of time. This coating system is pH sensitive and is designed to help provide a prolonged delivery-further enhancing the extended release capacity of Dymatize Elite XT. After a battery of tests and trials, we have developed a calculated protein timing system that we call Sustained Muscle Saturation Technology (SMST). How does SMST work? Different proteins have different chemical compositions and different rates at which they can be assimilated by the body. By developing an absorption "time-line" of the highest quality proteins, we were able to create the basis of Elite XT. To develop Dymatize Elite XT, every facet of protein usage was analyzed. Nitrogen retention, absorption as well as several other factors including specific amino acid profiles were examined. Some of these additional factors included: 1-Rate of Absorption (RA): The rate each different protein source releases its amino acid. 2-Protein Digestibility Correct Amino Acid Score (PDCAAS): An evaluation "best method" used by the FDA and FAO/WHO, which uses nitrogen absorption and amino acid profile to rate quality. 3-Amino Acid Profile: Each protein source has its own unique amino acid profile. 4-Biological Value (BV): Derived from the amount of Nitrogen absorbed over the amount of Nitrogen incorporated into the body. Helps determine the amount of protein absorbed from different protein sources.
