When to take folic acid tablets

Folic acid tablets taken orally during the first 3 months of pregnancy and 3 months after pregnancy can effectively prevent neural tube defects in fetuses. Because folic acid deficiency in pregnant women can lead to cysteine accumulation in the body, cysteine has embryotoxicity, which can easily lead to neural tube defects in fetuses, such as hydrocephalus and spina bifida, oral folic acid can effectively prevent neural tube defects in fetuses. After the second trimester of pregnancy, because the fetus has developed and will no longer show fetal neural tube defects, pregnant women can no longer take folic acid orally, but pregnant women with folic acid metabolism disorders may lead to folic acid deficiency and anemia if they do not take additional folic acid supplements, so these people can take folic acid orally throughout pregnancy.
