Folic acid is a B vitamin (B9) that plays a crucial role in pregnancy. It's the manufactured form of folate that your body converts and uses as a dietary supplement.

Who Needs Folic Acid?

All women during early pregnancy and those planning to conceive need folic acid. Since many pregnancies are unplanned, the nutrient is recommended for all women of childbearing age.

Why is Folic Acid So Important?

During the early weeks of pregnancy, the fetal brain and spinal cord are developing very quickly. Folic acid supports this critical growth and helps:

  • Reduce the risk of neural tube defects like spina bifida
  • Support DNA production and genetic material
  • Aid cell division during rapid fetal growth
  • Produce healthy red blood cells

How Much Do You Need?

A daily supplement of 400 micrograms (mcg) is advised for all women of childbearing age. This should ideally be taken:

  • Before conception - start at least 1 month before trying to conceive
  • During the first 12 weeks of pregnancy (at minimum)
  • Many healthcare providers recommend continuing throughout pregnancy

Food Sources of Folate

While supplements are recommended, you can also boost your intake through diet:

  • Dark leafy greens (spinach, kale, broccoli)
  • Fortified cereals and breads
  • Citrus fruits and juices
  • Beans and lentils
  • Avocado
  • Asparagus

Important Notes

Since many women don't get sufficient folic acid from diet alone, supplements are strongly recommended. Maintaining a balanced diet and healthy lifestyle remains essential throughout pregnancy and all life stages.

If you're planning a pregnancy or have just found out you're pregnant, speak to your GP about folic acid supplementation.
