of evidence suggesting that high levels of vitamin A may
cause birth defects, women who are (or may become)
pregnant are advised not to take vitamin A supplements
(including tablets andfish liver oil drops), except on the
advice of a doctor or an antenatal clinic; nor should they
eat liver or products such as liver paté or liver sausage.

mothers taking large doses.

initiated with very high doses of vitamin A and the child
