Whey by Animal. Details:Clear whey protein isolate is a new and innovative way to consume protein. Through advanced filtration technology, much of the lactose and fat is removed, leaving behind a pure protein isolate. The resulting powder is then mixed with water and other ingredients to create a clear, refreshing drink. Unlike the traditional whey protein isolate that has thick and creamy texture, clear whey protein isolate is smooth and refreshing. Clear whey is a great tasting protein powder that you can use anytime; day or night.
