GNC Pro Performance Whey Isolate provides the highest quality whey isolate protein available with a higher amino acid profile gram for gram than ordinary whey protein. The Benefits of Isolate Whey Protein – Whey Isolate is dually-processed using micro filtration and ion-exchange to ensure an isolated whey protein that contains up to 95% protein with minimal lactose and fat. These isolation processes separate the valuable protein from non-protein materials yielding a highly-purified whey isolate. Protein serves as a dietary source of amino acids. The body needs amino acids to build the various proteins used in the growth, repair and maintenance of body tissues such as skin, bones and muscles. The Benefits of BCAA – Whey protein offers the benefits of supplying high nutritional value and branched chain amino acids (BCAA) to athletes. BCAA are essential amino acids, which are part of muscle protein. They may preserve muscle glycogen stores and help reduce the amount of protein breakdown during exercise. Additionally, the natural components of whey help to enhance the body’s production of glutathione, a natural antioxidant, which may provide dietary support to the immune system. Whey also yields a high biological value, which measures usable grams of amino acids used by the body after intense exercise. Depending on your athletic goals, your protein requirements can vary, inadequate protein in your diet can limit muscle protein synthesis which can compromise your athletic goals. The amino acids from whey protein move quickly through the digestive system and are more readily absorbed. The consumption of these proteins will result in a rapid rise in blood amino acids and stimulate protein synthesis. Whey protein can be taken immediately before and/or after your workout to support muscle protein synthesis.
