Applied Nutrition Critical Whey Protein is developed using a unique blend of whey protein concentrate, whey protein isolate and hydrolyzed whey protein. The protein concentrate is produced by ultra-filtration technology containing high levels of protein and branched chain amino acids (BCAA). The protein is a pre-digested protein that has been enzymatically broken down into peptides. These high biological value and easily digestible proteins support muscle growth and maintenance.1 The protein provides 21 g of protein, 4.8 g of naturally occurring BCAAs and 4 g of glutamine per serving. Critical Whey Protein is a Halal certified product.
