        			Casein is a high quality protein isolated from milk, and commonly described as "slow-digesting" because it is broken down more slowly than whey, egg, pea, or soy. The advantage of extended digestion time is hours-long delivery of amino acids - an attribute that is particularly advantageous throughout the night while you sleep.Built from a novel mix of native micellar casein, micellar casein, partially hydrolyzed casein, and alpha-lactalbumin, PROMASIL CASEIN is as timely as it is time-released. Stack it with PROMASIL or NATURALLY FLAVORED PROMASIL for around-the-clock protein coverage.
