Casein / Night protein

Casein is also commonly known among strength athletes as night protein. Like Whey, it is a milk protein, but it takes longer to be processed in the body. The reason for this are the larger molecules (compared to Whey) which must first be broken down into smaller building blocks.

This longer lasting protein intake, is why many athletes take a casein shake before bed. It ensures that sufficient protein is available during this phase of recovery and muscle growth.
