Low Temperature Undenatured Whey Protein Concentrate is a form of Whey Protein typically low in fat and cholesterol, containing bioactive compounds as well as Carbohydrates in the form of Lactose and rich in both branch chain Amino Acids (BCAAs) and Glutamine. Undenatured means that the whey is cold processed, rather than being heated to high temperature, allowing it to maintain all of its Amino Acids.
