Folic acid and pregnancy

Even before you are pregnant, folic acid plays an essential role in your baby’s development. So why is it so important, and how do you get the right amount?


What is folic acid?

Folic acid, known as folate in its natural form, is one of the B vitamins. It cannot be stored in your body, so it is important to include it in your diet every day.


Why do I need it?

Normally, the main function of folate is to work together with vitamin B12 to form healthy red blood cells. But if you are trying to conceive or are pregnant already, it plays a crucial role in the development of your unborn baby. It helps to protect against neural tube defects such as spina bifida, a condition where the spine does not form properly.


How much do I need to take?

In pregnancy, you need 400 micrograms of folic acid a day. It is difficult to get this amount from food alone, so you should start taking a supplement from the time you stop using contraception until the twelfth week of pregnancy. This is the most crucial period in your unborn baby's development. If you fall pregnant unexpectedly, start taking a supplement as soon as you find out that you are expecting and ask your GP or midwife for advice.

As well as taking a supplement, try to eat plenty of foods that are naturally rich in folate. These include green vegetables, especially broccoli, asparagus and peas, as well as chickpeas, brown rice, fortified cereals and bread, oranges and bananas.

 

Higher doses
In some cases, you might need to take a higher daily dose of folic acid, for example if you have epilepsy or diabetes or if you have already had a pregnancy affected by a birth defect of the brain or spinal cord. If you think you fall into a higher risk group, it is important to consult your GP about folic acid before you start trying for a baby. Never take a higher dose of folic acid without medical advice.
