This is not an American Cod Liver Oil. This is a superior, non-defatted cod liver oil. Our Cod Liver Oil is a rich source of natural vitamin A, vitamin D, and the essential fatty acids: linoleic, linolenic, arachidonic, eicosapentaenoic (EPA), and docosahexaenoic (DHA) acids. These nutrients are critical for normal metabolism, brain and nerve function, and protecting and building the immune system. EPA and DHA are long-chain, omega-3 fatty acids found in cold-water fish and marine mammals that support a healthy cardiovascular system. Nutritionists recommend supplementing the diet with a small amount of cod liver oil, especially during the winter months, to ensure adequate dietary intake of vitamins A and D.* Independently tested for safety and purity.
