What kind of people are suitable for folic acid and ferrous sulfate tablets?

Patient's question:

No

Doctor's answer:

It promotes the maturation of immature cells in the bone marrow. If humans lack folic acid, it can cause megaloblastic anemia and leukopenia, which is particularly important for pregnant women. Folic acid deficiency can lead to neural tube defects in fetuses, thereby increasing the risk of anencephaly.
