Pregnancy is a special period when women's bodies undergo significant changes, and the demand for folic acid increases significantly.
In early pregnancy, the fetal neural tube begins to develop, and an adequate supply of folic acid is crucial for preventing fetal neural tube abnormalities.
If pregnant women lack folic acid at this stage, the risk of neural tube defects (such as spina bifida, anencephaly, etc.) in the fetus will significantly increase.
In addition, folic acid plays an irreplaceable role in fetal cell division and growth, promoting normal fetal development.
