Critical Whey Protein is made using a unique blend of whey protein concentrate and hydrogenated protein. Whey Protein Concentrate is produced by Ultra-Filtration Technology containing high levels of protein and branched chain amino acids (BCAAs). Whey protein is of the highest protein quality and is produced using Cross-Flow-Micro-Filtration. Whey Protein Hydro is a pre-digested protein enzymatically broken into Peptides. These high biological values provide easy digestion. Proteins support muscle growth and maintenance.
