How pure is the whey protein?
Whey protein contains impunities. Primarily, lactose(milk sugar) and ash. The method of processing determines the degee to which these impurities are filtered out of the final product. There are several methods to consider. Are the bioactive agents still present after processing? Whey protein concentrates have undergone an “ultra-filtration” process. These are the least processed and average around 80% purity. This can be an issue for lactose intolerant individuals. Whey protein isolates created by an ion-exchanged process contain fewer impurities than concentrates, but are lacking the beneficial bioactive elements present in the less processed whey protein concentrates. Whey protein isolates created by microfiltration, cold processing are considered the best source of undernatured whey protein. This process insures that the biologically active, undernatured fractions remain, while filtering impurities to create a pure product. Using a unique microfiltration cold process method, we pro
