Whey Protein Isolate

As a result of advanced microfiltration processing, whey isolate is without a doubt the purest, most potent form of whey protein available. Unlike whey concentrate, for example, it contains little to no fat, lactose or cholesterol. What it does contain, however, is a complete amino acid profile, along with other key growth factors such as alphalactalbumen and glycomacropeptides. Whey isolate is fast-acting, highly bioavailable and packed with pure, muscle-building power. For the highest quality whey isolates, look for Ultra-Microfiltered or Cross Flow Microfiltered (CFM) processing. <<
