Nordic Naturals offers great-tasting and trusted fish oil blends. Nordic Naturals creates every fish oil product from Arctic Cod Liver and does not contain fish body oils or synthetic vitamins. Pure Arctic Cod oil contains the highest levels of DHA, vitamin A, and vitamin D content of any type of cod. Nordic Naturals uses nitrogen to keep exposure of oxygen at a minimum. Exposure to oxygen leads to the fishy taste and smell of products. Nordic Naturals takes pride in having great-tasting fish oils that do not smell fishy.
