Folic acid prevents serious birth defects of the brain and spine and helps your body make new cells.
People often call it folate when it appears in food, but supplements usually use the synthetic form folic acid.
Most important: women who might get pregnant should take 400 micrograms daily to cut neural tube defect risk.
If you have certain health conditions, take specific medicines, or had a previous pregnancy affected by a neural tube defect, doctors may recommend a higher dose.
How much folic acid is safe? Typical daily limits for adults are up to 1000 micrograms from supplements, but follow your provider's advice.
Food sources matter: dark leafy greens, lentils, chickpeas, asparagus, and fortified cereals are good picks.
If you prefer a supplement, choose one labeled folic acid with the right dose and a reputable brand.
Timing is key: neural tube defects happen early in pregnancy, often before a woman knows she is pregnant, so start supplements before conception.
Signs of deficiency include fatigue, mouth sores, pale skin, and shortness of breath, but tests are the only sure way to know.
Interactions: certain medicines like methotrexate, some anticonvulsants, and sulfasalazine can lower folate levels or affect how folic acid works.
High folic acid from supplements can hide a vitamin B12 deficiency, so older adults should check B12 levels before taking large doses.
Pregnancy and planning: start 400 mcg daily at least one month before trying to conceive and continue through the first trimester, or follow your clinician's plan.
Quick tips: keep pills in a cool dry place, check expiration dates, and tell your doctor about all medicines you take.
When to call a professional: severe weakness, numbness, unusual bruising, or concerns about pregnancy need prompt medical advice.

Most adults get enough folate from food, but supplements help during pregnancy and with some health issues. If you are pregnant, many clinicians recommend 600 micrograms daily; for those with past neural tube defects, doses of 4 to 5 milligrams may be prescribed under medical supervision. Do not exceed recommended doses without a doctor's ok, and check labels if you take a multivitamin to avoid doubling up.
Look for supplements with clear labeling of micrograms or mcg and a listed manufacturer. A basic prenatal vitamin usually covers folic acid plus iron and other nutrients, which can simplify daily routines. If you take medication, compare possible interactions by checking the leaflet or asking a pharmacist. Choose a brand with third-party testing when possible to ensure purity and accurate dosing. Keep records of what you take and bring them to appointments so your clinician can recommend adjustments. If you notice odd symptoms after starting a supplement, stop and seek medical advice quickly. Simple tracking prevents overdoses and supports better pregnancy outcomes every time.
