Universally recognized as one of the most important macronutrients, protein comes in many shapes and forms, from many different sources. It is the material that builds muscle and virtually every other tissue in the body, including bones, ligaments, tendons, blood cells, and so forth. Two vital criteria determine the quality of a dietary protein and, thus, the nutritional value it provides--digestibility and amino acid composition. High digestibility means that the aminos from which the dietary protein is built can be readily released, while amino acid composition reflects the amounts and ratio of the protein's essential aminos as measured against the body's requirement for them. Ascential Protein is a highly-digestible, ultraquality blend of proteins that provide the exact profile of aminos needed by your body. This extremely low-fat, low-carb formulation is further augmented with vitamins, minerals, and free branched chain amino acids (BCAAs) required for proper protein metabolism and muscle physiology.*
