Whey protein is derived during the production of cheese. It is highly concentrated and easy to drink. This allows you to ingest large amounts of very high quality, muscle building protein very quickly. If you are busy and don’t have time to eat real food protein, then whey protein is a life saving food. In addition to being very convenient, whey is also has the distinction of being the protein source that delivers more amino acids per quantity than any other.
I highly recommend using a good whey protein supplement. This is essential if you want to increase your protein intake. You can choose a pre-mixed product like Myoplex, which combines whey protein with carbohydrates. These are best used as meal replacements. Or, you can simply use a pure whey protein powder like Precision Protein. I use this type of product to add additional protein to my real food meals.
