Elite XT Extended Release protein is designed to be ultimate muscle fuel and workout recovery formula. Knowing that protein helps repair muscles 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. After a battery of tests and trials, Dymatize developed a protein absorption 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 "timeline" of the highest quality proteins we were able to create the basis of the 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 include:Rate of Absorption (RA): The rate each different protein source releases its amino acids.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.Amino Acid Profile: Each protein source has its own unique amino acid profile.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 proteins sources.Net Protein Utilization (NPU): is used to determine the ideal mount of essential amino acids. Dymatize observed that no single existing protein source was ideal for achieving extended release effects. The optimal source was found to be a blend of several different protein sources, plus the addition of free form branched chain amino acids and other free form amino acids. Milk derived proteins such as micellar casein and whey protein ...
