Folic acid: what it does and why you should care

Missing one tiny vitamin can change a pregnancy’s outcome. Folic acid is that tiny, powerful vitamin. It helps make DNA, supports cell growth, and prevents major birth defects in the first weeks after conception—often before a woman knows she’s pregnant.

When to take and how much

For most adults, a daily 400 micrograms (mcg) supplement covers basic needs. If you’re planning pregnancy or could become pregnant, aim for 400–800 mcg daily. Pregnant people usually take about 600 mcg daily. If you’ve had a previous pregnancy affected by a neural tube defect, doctors often prescribe a higher dose—commonly 4 milligrams (4,000 mcg)—but that needs a prescription and medical supervision.

Food folate and folic acid from supplements aren’t identical. Food folate is natural; folic acid is the synthetic form used in supplements and fortified foods. Some people carry MTHFR gene variations and may absorb folic acid less efficiently—your doctor may recommend methylfolate in that case.

Where to find it and who should be tested

You get folate from leafy greens, beans, citrus, and fortified cereals. Supplements are cheap and widely available; prenatal vitamins almost always include folic acid. If you take anticonvulsants, methotrexate, or have certain gastrointestinal conditions, your provider may check folate levels and adjust doses.

Watch out: taking high folic acid can hide a vitamin B12 deficiency. That means blood counts might look normal while nerve damage continues. If you have anemia, tingling, or balance issues, ask your clinician to check both B12 and folate.

Signs of folate deficiency include fatigue, pale skin, forgetfulness, and shortness of breath. These can overlap with other conditions, so testing is the only reliable way to know. Pregnant people should have routine prenatal labs that include folate-related checks when indicated.

Buying folic acid online? Pick a pharmacy with clear contact info, SSL (secure site), and good reviews. Look for standard labeling: micrograms (mcg) and the exact form—folic acid or methylfolate. High-dose folic (4 mg) should only be sold with a prescription; avoid vendors that promise prescription-only doses without asking for one.

Quick tips: take folic acid with food if it upsets your stomach, store it in a cool dry place, and keep a consistent daily schedule for best results. If you’re unsure about dose or form, talk to your pharmacist or doctor—especially before pregnancy or when using other medications.
