Although a healthy diet will give you most of the vitamins and minerals you need, folic acid and vitamin D are so important for your baby that you should take supplements in pregnancy to be sure that you are getting the full amount you need.
If your blood tests show that you are anaemic in pregnancy then your doctor or midwife will prescribe an iron supplement. If they do not show this there is no need to take an iron supplement in pregnancy.
There is no advantage in taking other vitamin and mineral supplements unless your GP prescribes them.
Do not take vitamin A supplements, or any supplements containing vitamin A as too much could harm your baby.
