From The Makers Of Muscle Milk. Micellar Casein Protein Powder Drink Mix. 25g Protein. 100 mg Aminogen®. Lactose Free. Vanilla Crème Flavor. New! From the Makers of Muscle Milk®. Anti-Catabolic. Complete Casein. . A single serving of Complete Casein delivers 25 grams of Anti-Catabolic slow digesting protein from Micellar Casein and Calcium and Sodium Caseinates. Complete Casein forms a gel in the stomach and 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 provides Amino Acids over a longer period than whey protein. This prolonged amino acid availability is what makes Complete Casein anti-catabolic. . Complete Casein also contains Aminogen® (a patented digestive enzyme complex) to help promote efficient and more complete protein utilization and absorption. Complete Casein is Lactose and Gluten FREE so it is suitable for almost anyone looking to increase their protein intake. It mixes easily in a shaker and has that great Muscle Milk-like taste.
