Casein protein is the primary protein found in milk and makes up to 80% of the protein in the glass.
The other 20% is made up of whey protein, so milk itself is a great muscle builder.
But to use specifically for muscle building, there are protein powders available.
Casein protein is a great supplement to use instead of whey at bedtime since it has a slower digestion and absorption rate.
This provides a more steady supply of amino acids for the body to use for processes while you sleep, meaning that the body doesn’t take them from muscle to function.
By being able to keep all of the amino acids for themselves, the muscles are then able to continue to grow and repair as you sleep.
