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.
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.
