DYMATIZE ELITE CASEIN provides 24 grams of slow release casein protein per serve. Dymatize Casein is specifically designed to be absorbed more slowly in your body as opposed to other rapid release protein sources such as wpi or wpc. This slow digestion is caused by the natural pH sensitivity of casein protein in the digestive system. Because casein is naturally thicker a steady release of protein is obtained and casein absorption can take more than twice as long as your traditional forms of protein. Delayed digestion is ideal at bedtime or other periods of the day where as rapid absorbing proteins are not required.
