Folic acid throughout pregnancy?

Folic acid supplements should be taken throughout pregnancy, depending on the folic acid genotype of the pregnant woman. Under normal circumstances, folic acid tablets should be taken during pregnancy preparation. If the folic acid genotype of the pregnant woman is CC type, the pregnant woman can stop taking folic acid tablets after 12 weeks of pregnancy. If the folic acid genotype is CC type or TT type, it is recommended to take folic acid tablets orally until the third trimester of pregnancy and throughout pregnancy. The purpose of folic acid supplementation before pregnancy and during pregnancy is mainly to prevent fetal open neural tube defects. Pregnant women are advised to take folic acid tablets on time. It is best to guide the time and dosage of folic acid according to the folic acid genotype. They can also supplement some folic acid through food.
