Question

A 28-year-old woman planning pregnancy asks which vitamin form should be emphasized to reduce neural tube defect risk, and what is the difference between the dietary and supplemental forms?

Accepted Answer

Folate (naturally occurring in foods) and folic acid (synthetic form in supplements); folic acid is the supplemental form used to reduce neural tube defect risk during pregnancy.

Answer

Biotin (B7) is superior to folate because it is more bioavailable and is the only B vitamin that prevents neural tube defects when taken in the first trimester.

Answer

Cobalamin (B12) is the most critical preconception supplement because the natural form in foods prevents neural tube defects more effectively than any synthetic form.

Answer

Pantothenic acid (B5) should be emphasized because its coenzyme A derivatives are necessary for fetal neural tube closure and are the preferred supplemental form.
