Whey protein is a very high quality protein supplement derived from milk. It is filtered from cows milk as part of the cheese making process. The whey protein fractions are passed through a set of filtration systems that remove the unwanted fat and lactose, leaving the concentrated whey protein in a liquid suspension. The whey is then usually spray dried or dried at low temperature and pressure.
