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!

Muscle Fuel Around the Clock

Optimum Nutrition has you covered day and night. Try Optimum Nutrition 100% Whey Gold Standard before and immediately after workouts for a fast-acting rapid shot of amino acids right when you need it, and Optimum Nutrition 100% Casein Gold Standard between meals and before bed for prolonged, sustained coverage.

Optimum Nutrition Gold standard natural 100% casein helps me meet my protein goals without a bunch of artificial flavors or ingredients. I often take this before bed because it is a slow digesting protein. The flavor is subtle,but I like it and there isn't a weird after taste.*

The flavor is a good vanilla but the smell is like waffles in the morning. This is best when taken at night before bed. *

Optimum Nutrition Natural 100%Casein has a good, slightl hint of sweet taste. It doesn't taste like an amazing dessert like some other protein powders, but it allows you a chance to cut back on artificial sweeteners or sugar. Casein is a great slowly digested protein.*
