ISO-RUSH is derived entirely from premium rGBH Free (hormone free), Cross Flow Micro-Filtered (CFM) whey protein isolate. During manufacturing, micro-filtration separates lactose and minerals from the protein. We then use a special enzymatic process to reduce the remaining low level of lactose to its component sugars. The result is a completely undenatured and fully bioactive protein that is lactose-free and easy to digest.
