100% WHEY ISOLATE Extra L-Glutamine Added 100% Whey Isolate is an excellent quality protein exclusively from whey. Generally, whey “isolate” proteins are produced to have a higher percentage of protein than whey “concentrates”, which also means that “isolates” have lower sugar (including lactose) and fat content! Dietary proteins are the source of nitrogen and indispensable amino acids, which the body requires for tissue growth and maintenance. Therefore 100% Whey Isolate contributes to the growth and maintenance of muscle mass, and also to the maintenance of normal bones. Whey protein from milk is a so-called complete protein, because it provides the body with all the necessary types of amino acids, including the 9 amino acids the body cannot synthesize and must be supplied by the diet (i.e. Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine). 100% Whey Isolate has added L-Glutamine that is the most abundant free amino acid in human blood.
