Platinum 100% Iso-Whey uses only ultra-pure, microfiltered whey protein isolates, the purest form of whey protein you can feed your body. With a filtration process that uses precision technology to remove lactose, ash, and fat, Platinum 100% Iso-Whey delivers the major bioactive protein fractions you need in a premium formula. Many of the inferior whey formulas on the market use heat, harsh acids, and salts to isolate their whey protein. Unfortunately, these methods are severe enough to cause extensive denaturation of the whey protein structure.
