Milk contains two types of protein, namely whey and casein. The most common type is whey protein, but it is a matter of personal choice as to which type you prefer but there are several reasons why casein protein is more popular.

Casein is digested slowly and over a period of time, it is also more filling. Another reason for opting for casein is because of the molecular structure of the protein. Any health-conscious person who enjoys baking will tell you that casein protein is far better for making puddings and ice cream than whey.

Taking casein protein before going to bed aide with muscle recovery and helps to reduce muscle breakdown – all while you sleep. It also boosts muscle growth.

Because casein protein is derived from milk there is a positive effect on muscle recovery as well as growth. For the best results it is best to take casein protein just before bed as the body absorbs it slowly. This time gives the body the longest time to absorb the protein.

A point to remember is that casein protein has a shelf life. It should be stored at room temperature and will keep for 2 years if it stays sealed.
