Protein Powder

Protein powders come in various forms. The three common ones are whey, soy, and casein protein. Whey is the most commonly used, because it’s a water-soluble milk protein, says Peter Horvath, PhD, associate professor in the department of exercise and nutrition sciences at the State University of New York at Buffalo.  Also a complete protein, so it got all those advantages. (Complete proteins contain all nine of the amino acids necessary for human dietary needs.) People who are vegan may prefer soy protein, although Horvath notes that its taste is sometimes considered to be more unpleasant, and it doesn’t dissolve as well in water.
