Which statement about folate and neural tube formation is correct?

• A. Folate is essential for neural tube formation during early pregnancy.
• B. Folate is involved in calcium absorption.
• C. Folate is not involved in neural tube formation.
• D. Folate is required for collagen synthesis.

Answer: (A)

Folate supports rapid cell division and DNA synthesis through one-carbon metabolism, which is crucial as the neural tube forms in early embryogenesis. The neural tube closes in the first few weeks of gestation, so sufficient folate during this periconception period reduces the risk of neural tube defects such as spina bifida and anencephaly. That makes the statement about folate being essential for neural tube formation during early pregnancy the accurate one.

Folate isn’t primarily linked to calcium absorption, which involves other nutrients and factors, and it isn’t a key driver of collagen synthesis, which relies more on vitamin C and related cofactors.
