Casein protein is a slow-releasing protein with great muscle fueling potential. It features properties that slowly release amino acids into the bloodstream to feed muscles.

Formula re: Contains

It naturally provides key amino acids, such as glutamine and branched chain amino acids, so casein protein is excellent between meals and before bed for sustained amino acid delivery.

This chart compares the branched chain amino acid (BCAA) absorption after consuming casein and whey protein. When compared to whey, casein concentration was significantly lower after one hour, forty minutes, but increased after five hours. {Chart} Plasma Amino Acids CASEIN VS. WHEY PROTEIN ABSORPTION CASEIN WHEY 5 Hours *In a randomized, double-blind controlled study of sixteen healthy adults, subjects consumed either whey protein or casein containing equal amounts of leucine. While plasma branched chain amino acid (BCAA) levels were highest at 100 minutes post-supplementation in subjects who consumed whey protein, after 300 minutes (5 hours) BCAA levels were higher in subjects who consumed casein compared to those who took whey protein.
