Whey protein concentrate

Milk contains two types of protein - casein and whey protein. Whey protein is a fast digesting fraction of the milk protein, which represents 20% of the total protein content of milk and contains all essential amino acids. There are different types of whey protein, the most common of which are whey protein isolate and whey protein concentrate. The main difference is that whey protein concentrate has undergone less processing, which leads to its slightly higher lactose and fat content compared to whey protein isolate. This makes it suitable for weight gain and weight maintenance programs. The amino acid profile of whey protein has a higher amount of branched-chain amino acids (BCAAs) leucine, isoleucine and valine. Branched-chain amino acids exhibit anabolic function by being actively involved in the muscle cell protein synthesis. The rapid release of amino acids in whey protein, together with its specific amino acid profile, make it indispensable for intake at times when the body needs immediate intake of amino acids, such as the first meal of the day, the meals before and immediately after exercise. Taken at the right time whey protein provides the amino acids needed for protein synthesis in the muscle cells, thus exhibiting anabolic function and promoting muscle growth.
