What does it mean when pregnant girl is low on folate (folic acid)?

Folate (folic acid): Folate (folic acid) is very important in women who are pregnant, because it helps prevent neural defects in the developing baby. If a pregnant woman is low on folate (folic acid), (folic acid) it means she needs to make sure she is on a pre-natal vitamin right away. Even though they are called "pre-natal" vitamins, we still use them during pregnancy because of the folate (folic acid) and other vitamins they contain.
