Cod Liver Oil Gems are low in vitamin A and provide 230 mg of omega-3s per serving, which supports heart, brain, vision, and joint health. To ensure maximum freshness, our Cod Liver Oil is closely managed from sea to store. We source the highest quality, deep, cold-water fish off the coast of Norway using traditional, sustainable methods. The same day they're caught, our fish are delivered to a highly regulated Norwegian facility for processing and purification. Our Cod Liver Oil is encapsulated, while the rest of the fish is used for human and animal consumption, so no part of the fish is wasted. And like all Carlson omega-3s, this product is tested by an FDA-registered laboratory for freshness, potency, and purity.
