CASEIN

Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times including bedtime when your body typically goes for hours without food. Casein products are acid sensitive and thicken in the stomach. Casein protein provides the body with all of the amino acids necessary to help build muscle. Casein protein is digested more slowly than other proteins, so it might be better at reducing appetite and increasing feelings of fullness.
