Compared to whey proteins, Micellar Casein digests and absorbs more slowly. This property of casein leads to a sustained increase in amino acids and inhibits protein degradation to a greater extent. It also prolongs muscle protein synthesis (MPS) times up to 8 hours depending on the dose taken. This is why casein is an ideal nighttime protein. However, casein does not create as great of an anabolic response as whey protein when comparing the extent of which it elevates amino acid levels and stimulates MPS.
