Casein is an abundant protein in milk, serving as a building block of new muscle.
What are its health benefits?
Casein works as a slow-digesting protein, allowing for the more efficient use of amino acids.
Casein forms a gel as it comes into contact with stomach acid during digestion. This reduces the rate of digestion, creating a more efficient release and use of casein's amino acids. This means that muscles receive food over a longer period of time.
