While rapid protein digestion is desirable immediately before or after exercise, slower digestion is more appropriate for between meals and right before bed. Compared to whey, it can take significantly longer for micellar casein to be broken-down into its amino acid subcomponents. ON's Gold Standard 100% Casein was the first all-micellar casein and remains the best seller.
