Frequently asked questions
Why is folic acid important in pregnancy?
Folic acid (B vitamin) reduces the risk of neural tube defects (spina bifida, anencephaly) by up to 70%. It's crucial during the first 28 days of pregnancy, often before a woman knows she's pregnant, so preconception supplementation is recommended.
When should I start taking folic acid?
Start at least 1 month before trying to conceive and continue through the first 12 weeks of pregnancy. Women of childbearing age should maintain 400 µg daily.
What if I have a higher-risk pregnancy?
If you have a history of neural tube defect, diabetes, or certain medications, ask your doctor about high-dose folic acid (5 mg/day), which may be recommended 3 months preconception.
Can I get enough folic acid from food?
Fortified grains, leafy greens, legumes, and citrus contain folate, but supplementation during preconception/pregnancy ensures adequate levels (bioavailability of synthetic folic acid is higher than food folate).
Does folic acid interact with other supplements or medications?
Some medications (antiepileptics, methotrexate) deplete folate. Always review with your doctor before supplementing, especially if taking other meds.
