Folic acid is a water-soluble B vitamin, abundant in green leafy vegetables, fruits, and animal livers. It participates in the entire process of human metabolism and is a necessary vitamin for synthesizing important substances like DNA in the human body. Its deficiency can not only lead to neural tube defects in fetuses but also increase the incidence of malformations in organs such as the eyes, lips, palate, gastrointestinal tract, cardiovascular system, kidneys, and bones.
During the one month before pregnancy and the three months after, taking 0.4 milligrams of folic acid supplements daily can prevent most neural tube defects in fetuses.

1. Folic acid must be taken one month before pregnancy. The emphasis on starting before pregnancy is to maintain a certain level of folic acid in women's bodies, ensuring a better nutritional status for early embryonic development. Research shows that it takes four weeks for women to correct a deficiency in folic acid after taking supplements. This way, during the sensitive period of neural tube formation in early pregnancy, sufficient folic acid can meet the needs of nervous system development. Moreover, it must be taken consistently during the first three months of pregnancy to achieve the best preventive effect.
2. Women in areas with a low incidence of neural tube defects in China should also supplement with folic acid. The incidence of neural tube defects in China is higher in northern regions than in southern regions and higher in rural areas than in urban areas. Therefore, some people believe that women in low-incidence areas who are pregnant should...
