Neural tube defects occur when the bones of the spine do not correctly form, leaving the spinal cord and its nerves and coverings to protrude out through the skin (or lie just beneath it). The use of folate vitamins during pregnancy has decreased the incidence of neural tube defects.
This is because liver is also very rich in vitamin A, too much of which can cause birth defects in your baby. Some women have an increased risk of having a pregnancy affected by a neural tube defect and are advised to take a higher dose of 5 milligrams (5mg) of folic acid each day until they are 12 weeks pregnant. You have an increased risk if: you or your partner have a neural tube defect.
