Whey protein is not only a rich source of protein but also provides essential nutrients. It contains branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine, which play a crucial role in muscle protein synthesis. Additionally, whey protein contains essential vitamins and minerals, including calcium, phosphorus, and vitamin B12.
