Whey versus Soy Protein

The importance of protein supplementation is critical to any individual looking to build and maintain muscle mass. Protein has been called “the building blocks of life” and without proper protein supplementation the task of building and maintaining muscle mass is next to impossible.

There are several kinds of protein supplements available: milk and egg protein, soy, beef, and even vegetable protein; but the absolutely best source of protein is ion-exchange whey protein. This protein has superior biological value (which means it may yield more usable grams of protein than other protein supplements), plus it is very low in lactose (the substance in milk that causes a lot of stomach upset and gas in individuals).
