Folic acid is important for pregnant women, as it helps the foetus to develop healthily. It also reduces the risk of neural tube defects (NTDs) such as spina bifida.
Here is everything you need to know about folic acid.
When should I take folic acid?
The Department of Health recommends that women who are trying to conceive should take a daily supplement of 400mg of folic acid – and continue to take this dose during the first 12 weeks of pregnancy.
During the first 12 weeks of your pregnancy, your baby’s spine is developing so folic acid is very important. It is safe to continue to take folic acid after 12 weeks.
If you didn’t start taking folic acid supplements before you became pregnant, you can start to take them as soon as you find out.
A recent study published in the American Journal of Clinical Nutrition (AJCN) has suggested that cognitive skills in eight-year-olds could be increased if their mums continued to take folic acid after the first 12 weeks.
Dr. Carrie Ruxton from the Health Supplements Information Service commented:
“The results showed that the group of children whose mothers received folate supplements displayed a significantly better ability to solve response conflicts.
This is an important indicator of superior cognitive function because the process of solving conflicts involves understanding other people’s points of view, using language to resolve disputes and considering different strategies and solutions.”
How much folic acid do I need to take?
Your recommended daily allowance of folic acid is 400 micrograms a day if you're pregnant.
The NHS says your doctor may tell you to take a higher dose of folic acid if there's a higher risk of neural tube defects during your pregnancy.
You may have a higher risk if you have/are:
- Had a pregnancy affected by a neural tube defect
- Have a neural tube defect
- Or your partner have a family history of neural tube defects
- Have diabetes
- Very overweight
- Sickle cell disease
- Taking certain epilepsy medicines
Side effects of folic acid:
Although most adults don't experience side effects from taking folic acid, the NHS says high doses can cause:
- Feeling sick (nausea) - but if you're pregnant, this is more likely to be morning sickness
- Loss of appetite
- Bloating or wind
They advise talking to your pharmacist or doctor if these side effects bother you, get worse or don't go away.
While a healthy diet should give men all the folic acid they need, the science behind men taking on additional folic acid suggests that high levels of the nutrient in a man’s diet can lead to higher-quality sperm, which, in turn, leads to fewer birth defects.
A study by the University of California at Berkeley found that ‘men who had lower levels of folic acid in their diet had a higher rate of abnormal chromosomes in their sperm.’
The researchers found that men reporting the highest intake of folate (folic acid) had 19 percent lower rates of sperm with abnormal numbers of chromosomes than men with moderate folate intake, and 20 percent lower rates compared with men in the low folate intake group.
