Optimum Nutrition Gold Standard 100% Casein Protein is the protein formula that sets the standard for slow digesting protein support. If you run out of amino acids in your bloodstream and have a lack of protein in your muscles, your body can start breaking down muscle proteins to fuel itself. Casein Protein can make the real difference and allow you to take your training to the next level. Casein Protein can take up to 7 hours to digest, which is just about as long as the average person sleeps every night, and that makes it the perfect solution to avoid protein breakdown and amino acid oxidation during your sleeping period. 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 proteins are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take more than twice as long for Gold Standard 100% Casein to be broken down into its amino acid subcomponents.
