What can be done to decrease the risk of having a child with neural tube defect (NTD)?
The increased intake of folic acid (5.0 mg per day) has been shown to decrease the chances of having a child with a NTD. The Society of Obstetricians and Gynaecologists of Canada (SOGC) recommends that women who are at risk of having a child with NTD take a prenatal multivitamin supplement with a high dose of folic acid (5.0 mg) at least 3 months before and following conception.
