Instant protein (also known as protein powders/replacements) is a quick and easy way to replace or supplement your diet with additional or required protein. Someone who is in need of additional protein would drink this with or after a meal that is low in protein or possibly if the individual was looking at increasing the number of calories they needed daily. If you are interested in using a protein powder or instant protein supplement, we offer a variety of meal replacement and protein replacement/supplement drink choices in the dotFIT store.
