A High Quality Whey Protein derived from cow’s milk and is considered a complete protein because it contains all of the essential amino acids that can only be taken in through diet. Because of ultra-filtering and other processes, ON Performance Whey has much of the fat, carbohydrates and other undesirable components removed, leaving you with an easy-to-mix powder providing 24 grams of whey protein with just 1 gram of sugar and 1 gram of fat.
