Comparing Types of Protein Powders

Protein powders are generally rated by their Biological Value (BV). Basically, the higher the BV, the more of the protein your body can use. When choosing a protein powder, keep in mind why you are using it. Also, note that their is a difference between "concentrate" and "isolate."  "Concentrate" contains between 30% and 85% protein and tends to be easier to find and cheaper. "Isolate" contains 90% or more protein, and tends to be more expensive.
