Casein

Casein protein is one of the two main types of protein found in milk, the other being whey protein. Unlike whey protein, which is rapidly digested and absorbed by the body, casein protein is slowly broken down over a period of several hours. This means that it provides a sustained release of amino acids into the bloodstream, making it ideal for promoting muscle recovery and growth. Casein protein is particularly beneficial as a pre-bedtime protein supplement, as it can help to prevent muscle breakdown during the night when the body is in a fasting state.

It also includes a complete amino acid profile which naturally occur in protein and help to build and repair new muscle, before, during, and after workouts — so you can wake up ready for your next training session.
