If you go to a gym, you’ve probably heard the guys by the weight machines talking about the protein shakes they drink after a workout and what kind of shake they prefer. Protein powders -- made into a shake or consumed however you like -- are getting more and more popular as a nutritional supplement.

You can buy protein powders in every nutrition store and all over the Internet. You can even find pre-mixed, ready-to-drink protein shakes in many stores. But are protein powders just for bodybuilders, or can the average everyday athlete benefit from them as well? Protein powders can be helpful if you aren’t getting enough protein from whole food, or if you want the convenience and portability of a protein source that won’t spoil easily.
