Is it beneficial to take ferrous salt with folic acid while pregnant?

Yes: Many women are or can develop iron deficiency in pregnancy. The fetus requires iron to develop its hematologic and neurologic system, and will extract it from the mother even if the mother has little for herself. Taking supplemental iron is a good idea for most pregnant women for this reason.

Depends: Eating beets and red cabbage will provide iron. Instead of synthetic folic acid, take l-methylfolate.
