What is the recommended daily intake of folic acid before and during pregnancy?

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

Answer: (B)

Folic acid helps prevent neural tube defects when enough folate is available around conception, so starting before pregnancy and continuing through the early weeks is key. For most women, the recommended daily amount is 400 micrograms, usually taken as part of a prenatal vitamin. This amount raises maternal folate status to support the critical period when the neural tube forms. Foods fortified with folic acid and natural folate from leafy greens also contribute, but a regular 400 mcg supplement helps ensure adequate intake regardless of diet. Higher doses are reserved for specific high-risk situations under medical guidance (for example, a history of an NTD-affected pregnancy or certain epilepsy medications may require about 4 mg daily). The lower amount isn’t sufficient for prevention in most cases, and while larger amounts can be appropriate in certain circumstances, the standard recommendation for the general population is 400 micrograms daily.
