“Neural tube defects (NTDs) are birth defects of the brain, spine or spinal cord that happen in fetuses within the first month of pregnancy. NTDs are linked to folate (folic acid) deficiency before and during pregnancy, so it’s important to make sure you’re getting enough folate through supplements and in your diet before and during pregnancy.”
