Out of the many protein sources out there, whey protein is the ultimate. It comes from milk. During the process of turning milk into cheese, whey protein is separated out. Protein can be found in a variety of foods--mainly meats, such as fish, beef, and chicken.
Dairy products as well as eggs, cottage cheese, soy and vegetable protein also contain good amounts of protein. Nevertheless, none of these sources compares in quality or ease of use like whey protein. Whey protein has the highest value in providing branched-chain amino acids, which result in building and retaining muscle tissue.
