What supplements do I need in pregnancy?

There are 2 vitamins that are very important in pregnancy and you are recommended to take them as a supplement: folic acid and vitamin D. If you are anaemic, it may be important to take an iron supplement too.

A healthy, balanced diet will give you most of the vitamins and minerals you need during pregnancy. Folic acid and vitamin D are so important for your baby, that you should take supplements to make sure you are getting enough. 

If your blood tests show that you are anaemic in pregnancy, then your doctor or midwife will give you an iron supplement. Otherwise, you do not have to take an iron supplement in pregnancy. 

There is no need to take any other vitamin and mineral supplements unless your GP prescribes them.  Some women chose to take a pregnancy multivitamin, which is fine if you choose to do so.

Do not take vitamin A (retinol) supplements, or any supplements containing vitamin A, as too much could harm your baby.
