Answer:
We agree that processing can alter nutritional qualities of foods and supplements (see the dozens of articles in the Learn section).

Wysong E.F.A.™ is carefully prepared through gentle processing methods (the flax seed oil, for example, is cold extracted) and then packaged in light-impervious, nitrogen flushed (oxygen excluded) bottles. Additionally, a special natural Wysong antioxidant helps stabilize the fatty acids against oxidation.

Please see Dr. Wysong's Lipid Nutrition book and EFA™ monograph for more information (including scientific references): http://www.wysong.net/products/monographs/EFA.pdf.

To our knowledge, Dr. Weil is not an expert in lipid biochemistry or food processing and thus his opinion should be weighed against others with better credentials and experience in the field.
