What is the USPSTF recommended daily amount of folic acid for women planning pregnancy?

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

Answer: (A)

Folic acid before conception helps prevent neural tube defects by ensuring adequate folate during the early weeks of fetal development, when the neural tube closes around 28 days after conception. The USPSTF recommends all women who may become pregnant take 400 to 800 micrograms (0.4 to 0.8 mg) daily, starting at least one month before conception and continuing through the first three months of pregnancy. This range aligns with most standard prenatal vitamins and provides a baseline protective dose for most pregnancies. Doses outside this range are not the general guidance for all women planning pregnancy: too little may not reduce risk effectively, while higher doses are typically reserved for specific high-risk situations.
