Vitamin E mainly acts as an antioxidant in your body, combating harmful substances called free radicals. Vitamin E's antioxidant effects protect your body's cells from death or DNA damage, and also helps your body to utilize vitamin K and form red blood cells. Flaxseed oil contains both omega-3 and omega-6 fatty acids, particularly alpha-linonlenic acid, or ALA, which your body converts into docosahexaenoic acid, or DHA, and eicosapentaenoic acid, or EPA. Omega-3 fatty acids help your body to control inflammation, along with promoting overall health.
