What is the minimum daily folic acid intake for pregnancy?

• A. 400 mcg
• B. 100 mcg
• C. 800 mcg
• D. 200 mcg

Answer: (A)

Folic acid is essential in early pregnancy to support neural tube development, which occurs very early—often before a woman knows she’s pregnant. Adequate folate helps prevent neural tube defects such as spina bifida and anencephaly by ensuring proper DNA synthesis and rapid cell growth in the developing embryo. For most women, the minimum daily amount to protect against these defects is 400 micrograms. This baseline meets the needs for the general population, while higher doses are reserved for specific risk situations under medical guidance. Doses like 100 or 200 micrograms are typically not enough to provide this protective effect, and 800 micrograms is above the minimum rather than needed for the general case. So, the minimum daily folic acid intake during pregnancy is 400 micrograms.
