Why should I take folic acid?
Certain vitamins and minerals, including folic acid, have been shown to have a positive impact on the health of a 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.
When should I take folic acid?
You are advised to take folic acid every day while you are trying to get pregnant, and for at least the first 12 weeks of pregnancy while the baby's spine develops.
How much folic acid should I take?
Most women will be advised to take a 400mcg supplement.
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.
You will be advised to take a higher dose of 5mg if your baby has an increased risk of having neural tube development problems. The risk increases if you have diabetes or if you or your partner have a history of neural tube defects.

I am sorry to hear you have experienced two miscarriages. In trying for another baby, yes it would be great for you to start taking folic acid now whilst you are trying again to conceive.
It is impossible to know if you will have another miscarriage, but you can go to talk with your GP to seek advice as they know your full medical history and will know test results if you had any bloods taken after your second miscarriage.
Feel free to call our helpline if you have any more questions to ask.
All the best

If you are planning a pregnancy then we do advised for you to take a folic acid supplement of 400mcg for about 3 months before trying to conceive, although do not worry if you are also ready pregnant then start taking it straight away. In the article above it does explain that for some a higher dose is needed, so just checked if any of those things apply to you otherwise the usual dose is 400mcg.
Best wishes, Tommy's midwives
