Rapid protein use is desirable immediately before and after exercise to help refuel recovering muscles, but delayed digestion and absorption may be more beneficial at other times – including bedtime when your body typically goes for hours without food.*

Casein proteins are sensitive and tend to thicken in the stomach. Because of this, it can take more than twice as long for our Gold Standard Natural 100% Casein to be broken down into its amino acid subcomponents than other proteins. Gold Standard Natural 100% Casein is also free of artificial flavors, sweeteners, and synthetic colors and uses only premium micellar caseins to create a protein that's truly time-released.*

You can also use Natural 100% Casein Gold Standard in your meal replacement shakes!
