Cod liver oil also contains vitamin A and vitamin D. It has historically been taken because of its vitamin A and vitamin D content. It was once commonly given to children, because vitamin D has been shown to prevent rickets and other symptoms of vitamin D deficiency.

Famous quotes containing the words liver and/or oil:
“A life-worshipper’s philosophy is comprehensive.... He is at one moment a positivist and at another a mystic: now haunted by the thought of death ... and now a Dionysian child of nature; now a pessimist and now, with a change of lover or liver or even the weather, an exuberant believer that God’s in his heaven and all’s right with the world.”
—Aldous Huxley (1894–1963)
“Can he who has discovered only some of the values of whalebone and whale oil be said to have discovered the true use of the whale?”
—Henry David Thoreau (1817–1862)
