Also known as linseed oil, flaxseed oil is a natural source of both omega-3 and omega-6 essential fatty acids. It delivers linoleic acid, an omega-6 found in most vegetable oils and linolenic acid, an omega-3. Flaxseed oil supports cardiovascular health and skin health. It also features lignans, which are compounds that are converted by the body and have estrogenic and antiestrogenic activities and may play a role in menopause and PMS. Swanson EFAs Flaxseed Oil is made with OmegaTru® flaxseed oil, which ensures it is purely organic, cold pressed and guaranteed to deliver optimum EFA concentrations.
