With so many options out there, which is the best protein powder for building muscle?

In order to get an answer to that question, let’s first take a look at protein itself.

There are two main sources of protein out there: whole food protein and supplement protein.

Whole food protein is, as you guessed, protein that comes from natural food sources, such as beef, chicken, fish, etc. The best forms of whole food protein are chicken, turkey, lean red meat, fish, eggs, and milk.

Protein supplements are powdered or liquid foods that contain protein from various sources, such as whey (a liquid remaining after milk has been curdled and strained in the process of making cheese), egg, and soy (the three most common sources of supplement protein). You don’t NEED protein supplements to gain muscle, but it’s very impractical to try to get all protein from whole foods considering the fact that you will be eating protein 6-7 times per day.
