Optimum Nutrition Gold Standard 100% Casein Protein  (909 g, Mint Chocolate Chip)

While rapidly digesting whey protein is desirable immediately before and after exercise to help support muscle recovery,a slower digesting casein protein is the better choice between meals and especially right before bed when your body can go for hours without nutritional support.Casein proteins thicken in the acidic environment of the stomach and,compared to other proteins,it can take longer for our Gold Standard 100% Casein to be broken down into its amino acid subcomponents.By using only premium micellar casein as a protein source,we�re created a formula that sets the standard for slow digesting protein support.
