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.
