Milk Protein is a type of protein that is derived from filtered milk and Is formed from whey and casein proteins. Milk Protein is generally treated in a way that will keep these proteins close to their natural state, but in a purer form. The gentle purification process Milk Protein goes through ensures any denaturing or changing of the proteins is minimized and the Amino Acid profile remains excellent. The Milk Protein yielded is an excellent source of calcium, high in Branch Chain Amino Acids and low in fat. In this article we will investigate exactly what Milk Protein is and what makes it such an effective, if sometimes overlooked, protein source.
