When should I start taking folic acid?

Folic acid is particularly needed in the early weeks of pregnancy because it helps close the neural tube early on in the pregnancy.

Certain vitamins and minerals, including folic acid, have been shown to have an impact on the health of the growing baby. 

Folic acid supplements have been shown to dramatically cut the risk of having a baby with spina bifida or other problems affecting the baby's spine and neural tube. This is why women are advised to take a 400mcg supplement every day while they are trying to get pregnant, and for at least the first 12 weeks of pregnancy.

You should also try to eat foods that contain folate, which is the natural form of folic acid. These include:

  • green leafy vegetables
  • brown rice
  • some breakfast cereals

It is difficult to get the amount of folate that you need from food though so it is very important to take a folic acid supplement.

If you have diabetes or if you or your partner have a history of neural tube defects, your baby is at an increased risk of having neural tube development problems so you will be advised to take a higher dose of 5mg.
