Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day.

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 sub components. Because of these unique 'time released' qualities, caseins are aptly described as being anti-catabolic, or muscle protecting, proteins.By using only premium micellar casein as a protein source, ON has created a formula that sets the standard for slow digesting protein support.
