Can vitamin A cause neural tube defects?
Taking Vitamin A in doses larger than the Recommended Daily Allowance (RDA) can cause deleterious effects on the developing fetus during the critical period of embryogenesis namely Neural Tube Defects (NTDs).
What B vitamin prevents neural tube defects?
Folic acid is an important part of planning for a healthy pregnancy. CDC urges all women of reproductive age to consume 400 mcg of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain and spine (known as neural tube defects).
Which vitamin deficiency increases the risk of neural tube defects?
As with a vitamin B12 deficiency, a lack of folate can also affect an unborn baby’s growth and development in the womb (uterus). This increases the risk of neural tube defects, such as spina bifida, developing in the unborn baby.
What is the function of pyridoxine?
Pyridoxine, vitamin B6, is required by your body for utilization of energy in the foods you eat, production of red blood cells, and proper functioning of nerves. It is used to treat and prevent vitamin B6 deficiency resulting from poor diet, certain medications, and some medical conditions.
What birth defects can vitamin A cause?
The babies of women who consumed more than 10,000 international units of vitamin A daily — nearly four times the recommended amount — from supplements or food or both were more likely to be born with malformations of the head, heart, brain and spinal cord.
What is the best time to take pyridoxine?
Take this vitamin by mouth with or without food, usually once daily. Follow all directions on the product package, or take as directed by your doctor. If you have any questions, ask your doctor or pharmacist. If you are taking the extended-release capsules, swallow them whole.

What are the chances of having a neural tube defect?
The chances of a baby being born with a neural tube defect are 1 in 1000. Neural birth defects are caused due to a variety of reasons, most common one being genetics.

Helps women to get the recommended daily dose of 400 micrograms (mcg) of folic acid; and All women of reproductive age should get 400 mcg of folic acid each day to help prevent neural tube defects.
What are the genes associated with neural tube defects?
MTR, MTRR, MTHFR, and MTHFD are all genes that code for proteins involved in proper metabolism and transport of folate; variants in these genes are thus thought to be linked to the incidence of NTDs.
