(Carlson Labs) From the clean arctic waters far off the coast of 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. Separated without the use of chemicals. Natural vitamin E (10 IU) has been added to each 1000 mg soft gel to protect the freshness of EPA and DHA, both within the soft gels and our bodies. Promotes healthy heart, arteries, joints, brain-nerve function and bone strength.
