From the deep, unpolluted waters near Norway, Carlson brings you the finest cod liver oil which is naturally rich in Vitamin A, Vitamin D3, EPA and DHA. Only cod fish caught during the winter and early spring are used, as the liver oil content is highest at this time of year. The oil is separated from the liver tissues without the use of chemicals. To ensure freshness of Carlson Norwegian Cod Liver Oil, the air inside the glass bottle has been replaced with nitrogen.
