When most athletes think of protein, the first that comes to mind is usually whey protein. However, there are many types of beneficial protein supplements including whey isolate protein, casein protein, soy protein and egg protein. Protein is what muscle is made of, so it is a very useful and even necessary part of a body builder's diet. It is also useful for vegetarians, those on a strict diet, or anyone else who does not receive enough protein through their regular diet.
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. Peak Sports Nutrition has a huge range of Protein shakes and bars and Whey Protein supplements.
