Labrada's 100% Whey Protein is an excellent source of all the essential amino acids and is extremely rich in the Branched Chain Amino Acids (BCAAs), leucine, isoleucine, and valine. BCAAs make up one-third of muscle protein and are important to athletes because training increases the body's demand for them. An adequate supply of BCAAs in the blood is insurance against loss of muscle size and strength. Labrada's 100% Whey Protein is also high in glutamine, which accounts for approximately 60% of all free amino acids in the body. It is made by a unique micro-filtration process that involves NO heat or acid treatment like that used inion-exchange whey protein production. Labrada's 100% Whey Protein is gluten-free, perfect for individuals who must avoid gluten because they suffer from gluten sensitivities.
