Muscle Milk

Casein is one of the main elements of dairy products like cheese or butter because the milk protein contains nearly 80% of casein. Casein is generally used as casein protein powder and it is very popular. When a person takes it, it takes around 7 hours for it to be absorbed. If we compare it to other protein powders, casein protein powder has the longest absorption time. The main feature of casein is that it keeps glutamine in the muscle tissue, which is necessary for their growth. Another popular choice is whey protein but it is not as efficient as casein protein powder.
