Which group of individuals requires additional folate?

The need for additional folate is particularly crucial for women of childbearing age due to the significant role of folate in DNA synthesis, repair, and methylation, which are vital processes during the rapid cell division that occurs in early pregnancy. Adequate folate intake before conception and during early pregnancy helps prevent neural tube defects in the developing fetus. The recommendation for women in this group is to consume an additional 400 micrograms of folic acid per day to ensure that their levels are sufficient to support a healthy pregnancy.

While other groups like children, men over 50, and senior citizens may have dietary needs concerning folate, their requirements do not have the same urgency or specific health implications associated with pregnancy as those of women of childbearing age.
