How frequently should folic acid be taken during pregnancy?

During pregnancy, it is recommended that women take folic acid at a dosage of 400-800 mcg daily. This dosage is crucial because folic acid plays a vital role in preventing neural tube defects in the developing fetus. The recommendation holds true not just in the first trimester but continues throughout the entire pregnancy to ensure adequate levels are maintained as the fetus develops.

Folic acid contributes to DNA synthesis and cell division, which is particularly important during periods of rapid growth such as pregnancy. The higher end of this dosage range (800 mcg) is often emphasized for women with a history of neural tube defects or certain medical conditions that put them at higher risk. Regular intake starting at least one month prior to conception and continuing through the first trimester (and often throughout the entire pregnancy) helps optimize outcomes for both the mother and the baby.
