Other than whey protein, other sources like soy protein and egg protein are also important. Although these are not as popular or widely used as whey protein, each still has it unique benefits. We already got plenty of information on soy protein here, so no need to go in details about it here.
As for egg protein, its one of the "oldest" proteins used in bodybuilding. Egg protein comes from egg whites, which has the highest protein efficiency ration (PER) of 3.9. This even beats out whey protein's PER which is 3.2.
Many bodybuilders drink egg whites, or cook dozen of eggs at a time just to get enough egg protein; however, the high cholesterol content in eggs (especially the yolk) is rather unhealthy. Personally, I used to fry up 4 to 6 eggs every breakfast and throw away 1/2 of the yolks (which really isn't much compared to others). Even with this, I think I was getting much more cholesterol than I should've been taking in... now, I don't eat eggs too often, simply because of cholesterol reasons. Instead, its much easier, and healthier to get egg protein from powder, not to mention the convenience.
Egg protein has a full amino acid profile like whey protein, and is the ideal protein that offers optimal absorption and utilization by the body. Ok, enough about egg protein, and let's take a look at our comparison results in this final category.| Whey Protein Powder | Retail Cost | Online Price | Size (lbs) | # of Servings | Protein (g) |
