Dymatize Elite 12 Hour 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. 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 the 12 hour formula. We then added the advanced enzyme matrix Zytrix to more efficiently aid in the absorption of proteins, as well as a lipid blend that specifically promotes a longer absorption rate of the proteins allowing for a complete anabolic, nitrogen rich environment to be sustained in the body. To develop Dymatize 12 Hour Protein, every facet of protein usage was analyzed. Nitrogen retention and absorption is a combination of several different factors and each source of protein has its own results. Whey protein has the highest BV of any natural protein source, the highest rating of PDCAAS and forms the basis of our 12 Hour Protein. Top rated performers Milk and Egg Protein have also been added to fully enhance whey's effectiveness over a sustained period of time.
