Product Description

Optimum Nutrition Gold Standard 100% Casein protein makes up 80% of milk proteins as its digestion and absorption is much slower than that of any type of protein, and the amino acid composition helps build muscle and inhibits muscle wasting for long hours and leads to increased strength in Gym and muscle recovery speed after exercise.

The best time to take casein is at bedtime, long periods of time athletes go without pills, and during periods of fasting.

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. Casein products are acid sensitive and thicken in the stomach. Compared to some 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've created a formula that sets the standard for slow digesting protein support.
