Which statement correctly describes the role of folic acid in pregnancy?

• A. Improve iron absorption
• B. Increase vitamin D
• C. Prevent neural tube defects
• D. Boost calcium

Answer: (C)

Folic acid's main job in pregnancy is to support DNA synthesis and rapid cell division in the developing embryo, especially in the very early weeks. The neural tube, which becomes the brain and spinal cord, forms early in gestation, often before a woman knows she’s pregnant. Adequate folate intake during this critical period helps reduce the risk of neural tube defects such as spina bifida and anencephaly. That protective role is why the statement about preventing neural tube defects is the best choice. Folic acid does not directly alter iron absorption, vitamin D levels, or calcium levels, so those options don’t reflect its primary function in pregnancy. For context, guidelines commonly recommend starting folic acid before conception and continuing through early pregnancy to support this crucial developmental process.
