The CO2 critical liquid extraction process used by other greenlip mussel companies has the ability to extract ONLY the nonpolar lipids whereas our proprietary FREZZOR extraction process which involves either ethanol or a mixture of organic gases extracts BOTH the polar and non-polar fractions of the lipids from green lipped mussel powder. Our method also extracts members of a carotenoid family which are a series of potent antioxidants which provide many health benefits in their own right as well as working synergistically together with the omega 3 lipids and marine sterols found in greenlip mussels. – Jeremy Harris
