One of the best forms of protein is egg albumen. It is said to build muscle tissue and optimize health. Egg protein delivers the most complete amino acid profile that gives all the essential amino acids the body needs on a daily basis. Egg protein comes from natural animal sources and is the purest form of whole food in protein shakes.

Those who are allergic to dairy or are lactose intolerant can take egg protein powder instead. This powder is absorbed better into the muscle tissue than whey protein, which is made from dairy. Although whey protein is absorbed slightly faster, you still get more from a gram of egg protein into your body than whey.
