You must have heard the term ‘Whey Isolate’ in your muscle-building journey. Whey protein isolate is different from whey concentrate as whey protein isolate contains over 90% of protein. This is because of the major difference between the production of both the protein variations. Put simply, Whey protein isolate can be considered the purest form of whey protein as it contains as little as 1.5 grams of carbohydrate with no fat. In addition to this, ISO Whey Protein Series by Muscle Trail is best for people with lactose problems because of its low lactose content. There is no harm in consuming Whey Protein concentrate too, but if you want to settle only for high-quality protein without fats and carbohydrates, then ISO Whey should be your preference.
