Faster digesting protein is 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 products are acid sensitive and thicken in the stomach. Compared to some 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’ve created a formula that sets the standard for slow digesting protein support.
Optimum Nutrition Gold Standard Natural 100% Casein offers the slow-digesting protein essential for facilitating muscle recovery and preventing muscle breakdown. Rapid-protein use is desirable immediately before and after exercise to help refuel recovering muscles. However, 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 acid sensitive and thicken in the stomach. Because of this, it can take more than twice as long for Optimum Nutrition Gold Standard Natural 100% Casein to be broken down into its amino acid subcomponents than other proteins. This natural version of the industry’s first all-micellar casein contains no artificial flavors or sweeteners.
