What folic acid supplementation does the USPSTF recommend for women planning to or who could become pregnant?

• A. 0.4 to 0.8 mg daily
• B. 4 to 8 mg daily
• C. 0.04 to 0.08 mg daily
• D. 1 mg daily

Answer: (A)

Folate is essential for neural tube closure in the early weeks of development, often before a woman realizes she is pregnant. Because pregnancy can begin before conception awareness, USPSTF recommends that all women who could become pregnant take folic acid daily to prevent neural tube defects. The standard recommendation is 0.4 to 0.8 mg (400–800 micrograms) of folic acid each day, started before conception and continued through the early weeks of pregnancy. This amount provides enough folate for most pregnancies and is considered safe for the general population. Higher doses, such as 4 mg daily, are reserved for specific high-risk situations (like a previous pregnancy affected by neural tube defects) and are not the routine recommendation. Very small doses (40–80 micrograms) are generally insufficient for prevention, while 1 mg daily is above the typical general guidance for most women planning pregnancy.
