What is the commonly cited daily intake of folic acid to help prevent neural tube defects?

• A. 200 mcg
• B. 400 mcg
• C. 600 mcg
• D. 800 mcg

Answer: (B)

Folate is essential in early fetal development to support neural tube closure, which happens in the first weeks of pregnancy. Adequate folic acid intake before conception and during early pregnancy reduces the risk of neural tube defects in the baby. The commonly cited daily amount for most women who could become pregnant is 400 micrograms per day, taken as a supplement starting before conception and continuing through the early weeks of pregnancy. This dose provides protective benefit for the majority of pregnancies. Lower amounts, like 200 micrograms, may be insufficient, while higher doses (600–800 micrograms) are not routinely recommended for all women and are reserved for specific high-risk situations under medical guidance; very high doses (such as 4 mg) are for particular high-risk cases and require physician supervision.
