Milk is made up of two proteins: 80% Casein and 20% Whey. Casein differs from Whey as the absorption rate is much slower. This give Casein the distinct advantage of supplying the body with a steady supply of amino acids and nutrients for almost 12 hours after consumption. For this reason, Casein is often consumed before bed as this is usually the longest time the body goes without food.
Casein contains all 20 amino acids; they are the building blocks of protein and the body requires all of them to effectively build muscle. It is also considered a complete protein source because it contains all 9 essential amino acids that can only be obtained through diet.
The benefits of Casein aren’t only limited its effectiveness as a muscle builder, studies have also shown that it is a great weight loss aid, can reduce triglyceride (a type of fat) levels in the blood after eating and being an anti-catabolic protein sources meaning it prevents muscle wastage.
Casein is also naturally high in Calcium which supports strong bones and teeth.
