Q: I am clinically obese. How much folic acid should I take? Is it different from the regular recommended intake?
A: Yes, you are considered at high risk of having a baby with a defect of the brain and spine, called neural tube defects. It is recommended to take 4.0 mg of folic acid instead of 0.4 mg, which can be prescribed by your doctor, after consulting with them. You also need to eat folate-rich food, such as broccoli and fortified cereal.
Q: What's the best way to get the right amount of folic acid?
A: Before pregnancy, take a multivitamin that contains 400 micrograms (mcg) of folic acid every day. If women of childbearing age take 400 micrograms (0.4 mg) of folic acid every day before and during early pregnancy, it may help reduce their baby’s risk for birth defects of the brain and spin called neural tube defects (NTDs). Talk to your provider about taking a prenatal vitamin.
Q: I have insulin-dependent diabetes. How much folic acid should I take?
A:Some women, including those with insulin-dependent diabetes, have a higher risk of having a baby with a neural tube defect such as spina bifida. So, they need to take a daily multivitamin containing a larger dose of folic acid – 4.0 mg – after consulting with a doctor. They also need to eat folate-rich foods and take a higher dose of folic acid before and after conception.
Q: What is "synthetic" folic acid?
A: Synthetic folic acid is the simple, man-made form of the B vitamin folate. Folic acid is found in most multivitamins and has been added in Canadian and in the U.S. to certain foods in order to enrich them; e.g., bread, pasta, rice and breakfast cereals. The terms “folic acid” and “synthetic folic acid” mean the same thing.
Q: Is it okay to just wait until I’m pregnant – or planning to get pregnant – to start taking folic acid?
A: Birth defects of the brain and spine (anencephaly and spina bifida) happen in the first few weeks of pregnancy; often before you find out you're pregnant. By the time you realize you’re pregnant, it might be too late to prevent those birth defects. Also, even if you intend to take a supplement containing folic acid 30 days before you plan to conceive, about half of all pregnancies are unplanned, so it may be too late. For these reasons, even if you aren’t planning a pregnancy anytime soon, it’s still important for you to get at least 0.4 mg of folic acid every day, or more if advised by your healthcare provider.
Q: I'm planning to get pregnant this month. Is it too late to start taking folic acid?
A: If you haven’t been taking folic acid, it doesn't necessarily mean that your baby will be born with birth defects. However, it’s recommended that women planning to get pregnant take a supplement containing 0.4 mg of folic acid every day, starting at least one month before getting pregnant and during the first trimester.
If you’re trying to get pregnant this month, or anytime soon, start taking 0.4 mg of folic acid right away to reduce the risk of neural tube defects.
Q: I already have a child with spina bifida. Should I do anything different to prepare for my next pregnancy?
A: Women who’ve had one pregnancy affected by a birth defect of the brain or spine may be at a higher risk for having another child with a neural tube disorder. You should talk to your healthcare provider about taking a higher dosage of folic acid – up to 4.0 mg each day – at least one month before getting pregnant and during your first trimester and do so only upon his or her medical advice.

Q: Do I really need to take a folic acid supplement? Can’t I get enough folic acid by just eating a well-balanced and healthy diet?
A: It’s hard to eat a diet that has all the nutrients you need every day. Even with careful planning, you might not get all the vitamins you need from your diet alone. That’s why it’s important to take a vitamin with at least 0.4 mg of folic acid every day. Some foods are good sources of folic acid ; however, even if you track your daily consumption using a tool such as the VitaTrack Folate Tracker , you’ll likely find you’re not going to get enough folic acid to reduce the risk of neural tube defects without taking a supplement.
Q: I have trouble swallowing pills, so how can I make sure I get enough folic acid?
A: Some foods are good sources of folic acid. Check the labels on foods that have them, including breakfast cereals, to find out what percentage of the daily value (DV) of folate they contain. But remember that, even with careful planning, you might not get all the vitamins you need from your diet alone. The good news is that multivitamins containing folic acid now come in a variety of formats, including chewable tablets and liquids.
Q: How can I remember to take a vitamin with folic acid every day?
A: A simple way to remember is to take your vitamin at the same time every day, first thing in the morning or right before bed, for example. You can also try taking your vitamin when you brush your teeth, eat breakfast or lunch, finish your daily shower, or brush your hair. Leaving the vitamin bottle on the bathroom or kitchen counter in plain view can help you remember to take it, too. If you use a cell phone, you can program it to give you a daily reminder. If you have children, you can take your vitamin when they take theirs.
Q: Are there other health benefits of taking folic acid?
A: Folic acid may help prevent some other birth defects, such as cleft lip and palate and some heart abnormalities. Folic acid supplements may also be part of the recommended treatment for certain menstrual problems and leg ulcers, and there may be additional benefits – for both women and men. What’s more, folate deficiency may cause poor growth, graying hair, inflammation of the tongue (glossitis), mouth ulcers, peptic ulcer and diarrhea and/or result in hemolytic and megaloblastic anemias. Research is ongoing to confirm various health benefits. In the meantime, all adults should take 0.4 mg of folic acid every day.
Q: Is it better to take more than 0.4 mg of folic acid every day?
A: When taking supplements, more is not better. Women who can get pregnant (whether planning to or not) need just 0.4 mg of folic acid daily, and they can get this amount from vitamins or fortified foods. This is in addition to eating foods rich in folate. This amount may increase for high-risk women, whose healthcare providers may advise they take higher dosages for certain reasons.
Q: Can women get too much folic acid?
A: You can't get too much folic acid from foods that naturally contain it, but unless your doctor tells you otherwise, don’t consume more than 1 mg of folic acid a day. Consuming too much folic acid can hide signs that a person is lacking vitamin B12 (which can cause nerve damage), though lacking vitamin B12 is rare among women of childbearing age and most prenatal vitamins also contain B12 to help women get all they need. People at risk of not having enough vitamin B12 are mainly people 50 years and older and people who eat no animal products.
Q: What is folate and how is it different from folic acid?
A: Folate is a form of the B vitamin folic acid. Folate is found naturally in some foods, such as leafy, dark green vegetables, citrus fruits and juices, and beans. (For a longer list of food sources of folic acid, click here .) The body does’nt use folate as easily as folic acid. Currently, we can’t be sure that eating folate has the same benefits as consuming 0.4 mg of man-made (synthetic) folic acid each day. Women who can get pregnant should consume 0.4 mg of synthetic folic acid in addition to the natural food folate from a varied diet.
