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 acid sensitive and tend to thicken in the stomach. Because of this, it can take more than twice as long for our Gold Standard 100% Casein to be broken down into its amino acid subcomponents than other proteins. By blending premium micellar and calcium caseins, we've created a protein formula that's truly time-released. Typical Amino Acid Profile (Miligrams Per Serving): Essential Amino Acids (EAAs):Tryptophan 292, Valine 1609, Threonine 1039, Isoleucine 1312, Leucine 2129, Lysine 1822, Phenylalanine 1144, Methionine 644. Conditionally Essential Amino Acids (CAAs): Arginine 866, Cystine 79, Tyrosine 846, Histidine 688, Proline 2421, Glutamine & Precursors 4950. Nonessential Amino Acids (NAAs): Aspartic Acid 1589, Serine 1396, Glycine 510, Alanine 664.

    I found an unusual way to drink the chocolate flavor. Put it in a glass, add just a bit of water in it and stir until smooth. It makes a “pudding” that actually tastes really good and is now my late night snack. You need to play around with how much water to add to get the right consistency. This doesn’t work with any other protein powder I have tried.


      This stuff is great!

      This stuff is great! Vanilla tastes good, I mix 12oz of skim milk with one scoop. Any less liquid and its like drinking glue mixed with sand. I take mine right before bed, and it seems to be working, im not starving when I wake up in the morning.

        Highly recommended for casein

        I’ve had great experience with several Optimum Nutrition proteins and this one is no different. Produces thick, tasty shakes that provide solid bang for the buck. Highly recommended for casein protein supplement.
