Optimum Nutrition 100% Naturally Flavored Casein Gold Standard Protein

Optimum Nutrition 100% Naturally Flavored Casein Gold Standard Protein has 24g of instantized, slow-digesting micellar casein to help refuel recovering muscles. Slow digestion and absorption may be more beneficial at other times - including bedtime when your body typically goes for hours without food.

Optimum Nutrition 100% Naturally Flavored Casein Gold Standard Protein contains no artificial flavors, sweeteners, or colors.
