A single serving of Complete Casein delivers 25 grams of Anti-Catabolic, slow digesting protein from Micellar Casein & Calcium & Sodium Caseinates. Complete Casein forms a gel in the stomach & intestines, slowing its digestion in comparison to more rapidly digesting whey proteins. Because Casein protein digests more slowly (typically 4-6 hours to completion) it may provide amino acids over a longer period than whey protein. This prolonged amino acid delivery is what supports complete casein's anti-catabolic properties. Complete Casein also contains Aminogen (a patented digestive enzyme complex) to help promote efficient & more complete protein utilization & absorption. Complete casein is Lactose & Gluten free so it is suitable for almost anyone looking to increase their protein intake. It mixes easily in a shaker & has that great Muscle Milk-like taste.
