Critical Whey™ Protein has been developed using a unique blend of whey protein concentrate, Whey Protein Isolate & Hydrolysed Whey Protein. Whey Protein Concentrate is produced by ultra-filtration technology containing high levels of protein and branched chain amino acids (BCAAs). Whey Protein Isolate is the highest quality of protein and is produced using cross-flow-micro-filtration. Hydrolysed Whey Protein is a pre-digested protein enzymatically broken down into peptides. These high biological value and easily digested proteins support the growth and maintenance of muscle.¹
