How much do I need?
A month before you start trying to get pregnant, you should be taking 400 micrograms (mcg) of folic acid a day to reduce your baby's risk of neural tube defects. (Your baby's neural tube starts to develop about three weeks after conception, which is about as soon as you're likely to find out you're pregnant.) In fact, since half of pregnancies are unplanned, the U.S. Public Health Service recommends that all women of childbearing age get 400 mcg of folic acid each day.
Once you're pregnant, you'll need at least 600 mcg daily, although many practitioners suggest 800 mcg and some prenatal vitamins contain 1,000 mcg. Folic acid is a water-soluble vitamin, so your body will flush out the excess if you take too much. For some women, there's an exception to this rule; getting too much folate may hide a B12 deficiency. It's uncommon to be low in B12 if you're a healthy young woman with a varied diet, but it can be a problem for you if you're a vegetarian, particularly if you don't consume dairy products. Ask your healthcare provider if you think you may be at risk.
Women who've had a child with a neural tube defect have a significantly higher risk of having a second with the same defect. Healthcare providers now advise these women to take ten times as much folic acid 4,000 mcg or 4 milligrams (mg) starting one month before conception and continuing through the first three months of pregnancy. See your practitioner for a prescription for the supplement if you fall into this category.
