More info

Faster digesting amino acids are 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 proteins are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take more than twice as long for Gold Standard 100% Casein to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, ON has created a formula that sets the standard for slow digesting protein support.

Micellar Casein is the slowest digesting form of casein. It is separated from milk through an ultrafiltration process. One of Micellar Casein’s unusual properties is its ability to gel during digestion so it can release a steady flow of amino acids over many hours.

Using a shaker cup is the easiest and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein to a shaker cup filled with 300 - 350 ml of your preferred beverage. Cover and shake for 25 - 30 seconds.
