- 10 micrograms of vitamin D each day throughout your pregnancy and if you breastfeed
- 400 micrograms of folic acid each day – you should take this from before you are pregnant until you are 12 weeks pregnant
Do not take vitamin A supplements, or any supplements containing vitamin A (retinol), as too much could harm your baby
Folic acid before and during pregnancy
it can help prevent birth defects known as neural tube defects, such as spina bifida. You should take a 400 microgram folic acid tablet every day while you are trying to get pregnant and until you are 12 weeks pregnant. If you didn’t take folic acid before you conceived, you should start as soon as you find out that you are pregnant.
Neural tube defects develop in the first 28 days after conception, before many women know they are pregnant. Because about half of all pregnancies are unplanned, it’s recommended that any woman who could get pregnant take 400 micrograms (mcg) of folic acid daily, starting before conception and continuing for the first 12 weeks of pregnancy.
Some women have an increased risk of having a pregnancy affected by a neural tube defect, and are advised to take a higher dose of 5 milligrams (5mg) of folic acid each day until they are 12 weeks pregnant. Women have an increased risk if they:
- or their partner have a neural tube defect
- have had a previous pregnancy affected by a neural tube defect
- or their partner have a family history of neural tube defects
- have diabetes
In addition, women who are taking anti-epileptic medication should consult their GP for advice, as they may also need to take a higher dose of folic acid.
Vitamin D in pregnancy
Vitamin D regulates the amount of calcium and phosphate in the body, these are needed to keep bones and teeth healthy.
You need to take vitamin D during your pregnancy to provide your baby with enough vitamin D for the first few months of its life. You should take a supplement of 10 micrograms of vitamin D each day when you are pregnant and if you breastfeed
In children, not having enough vitamin D can cause their bones to soften and can lead to rickets (a disease that affects bone development in children).
The best source of vitamin D is summer sunlight on your skin. The amount of time you need in the sun to make enough vitamin D is different for every person, and depends on things such as skin type, the time of day and the time of year. However, you don’t need to sunbathe: the amount of sun you need to make enough vitamin D is less than the amount that causes tanning or burning. If you have dark skin or always cover your skin, you may be at particular risk of vitamin D deficiency. Talk to your midwife or doctor if this applies to you
