SLOW-DIGESTING PROTEIN FOR OVERNIGHT RECOVERY
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. Caseinate products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer for Optimum Nutrition Gold Standard 100% Casein to be broken down into its amino acid sub components. By using only premium micellar casein as a protein source, Optimum Nutrition has created a formula that sets the standard for slow digesting protein support! Perfect for late nights to curb cravings and constant protein absorption throughout the night! Recommended and perfect to take in combination with 100% Whey for optimal daily protein intake!
Low in carbohydrates, fats and sugar, and high in BCAAs, Glutamine and Glutamic Acid, Optimum Gold Standard Caseinis an ideal meal replacement, pre-bed shake or guilt-free midnight snack to keep your muscles nourished and growing while you sleep.
