The same day they're caught, our cod are transported to a highly regulated Norwegian facility for processing and purification. Carlson Cod Liver Oil is bottled with a touch of vitamin E and is given a nitrogen flush to remove oxygen and to prevent oxidation. Like all Carlson omega-3s, freshness, potency, and purity are guaranteed.
