Hi, Folic acid is very important for the development of a healthy foetus, as it can significantly reduce the risk of neural tube defects, such as spina bifida. women should take a daily supplement of 400 micrograms of folic acid while they are trying to conceive, and should continue taking this dose for the first 12 weeks of pregnancy, when the baby's spine is developing. However, it is safe to continue taking folic acid supplements after 12 weeks.consult your obstetrician for furthur guidance.
