This Native Whey Isolate is made directly from fresh milk using a process that involves pasteurization, low-temperature micro- and ultra-filtration, and granulation in a special drying chamber. This special process maintains the protein structure in its complete form and keeps it rich in immunoglobulin, an antibody, and lactoferrin, a component of your immune system. Furthermore, there are no chemicals or other impurities in the raw material.
