Optimum Nutrition 100% Casein Protein, Cookies and Cream

Slow Digesting Premium Micellar Casein Protein

While rapidly digesting whey protein is desirable immediately before and after exercise to help support muscle recovery, a slower digesting casein protein is the better choice between meals and especially right before bed when your body can go for hours without nutritional support. Casein proteins thicken in the acidic environment of the stomach and, compared to 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're created a formula that sets the standard for slow digesting protein support.

Beyond The Basics

24 grams of slow-digesting micellar casein per serving with 60% of the daily value for Calcium. Provides nearly 5 grams of naturally occurring BCAAs (Leucine, Isoleucine & Valine) and nearly 5 grams of naturally occurring Glutamine & Glutamic Acid in every scoop.


Thicker, Richer Shakes

While whey protein shakes tend to be thinner in consistency, casein protein powder creates a thicker more richly flavored shake. When mixed into cold water or milk, micellar casein resembles an ice cream milkshake in texture. It's a solid foundation for using an electric blender to create endless varieties of smoothies with fruits, nuts and other ingredients.

Make Protein Ice Cream

Satisfy your sweet tooth with an amino acid packed protein treat you'll look forward to using as a before bed snack. Simply mix one scoop into half the amount of water or milk you normally use (5 to 6 ounce), place in the freezer for about 5 minutes and enjoy!

Optimal Usage Occasions

Before bed to provide amino acid delivery while you're asleep and between meals for lasting protein support.
