Folic Acid During Pregnancy: Why Doctors Prescribe It

Folic acid is a crucial vitamin required for early growth and development of the foetus. It helps in the development of the brain and spinal cord. The deficiency of folic acid might impact the child’s growth and result in developmental anomalies. Getting sufficient amounts of folic acid during pregnancy reduces the risk of these serious developmental birth defects affecting the baby’s brain and spinal cord.

The Natural And Synthetic Forms Of Vitamin B9

Folate occurs naturally in leafy greens and fruits like oranges and melons. It helps in the formation of red blood cells, regulates the nervous system, and supports heart health.

Folic acid is the synthetic version of vitamin B9 and the most stable and well-researched form. This is the form of vitamin B9 that is recommended during pregnancy. You can find folic acid in supplements and fortified cereals.

Why Do Doctors Recommend Folic Acid During Pregnancy?

The neural tube is formed in the first week of pregnancy, and from this neural tube the brain and spinal cord are formed. During these important developmental stages, folic acid is required. Folic acid deficiency can result in defects of the spinal cord and the brain and can also lead to severe problems such as neural tube defects (NTDs). Annually, it is estimated that nearly 300 foetuses in India are born with these NTDs. Some frequently seen NTDs are:

Spina bifida: In this NTD, the spinal column is left unprotected without covering of any bony tissue. It results in damage to the spine and to some nerves.
Anencephaly: an NTD that causes underdevelopment of the brain and brain structures and invariably results in death a few days after delivery.
Encephalocele: an NTD caused by the formation of a sac in the skull that contains brain tissue.

Benefits of Taking Folic Acid during Pregnancy

As discussed above, folic acid deficiency results in NTDs. A few babies may be permanently disabled, while a few with anencephaly die shortly after birth. Folic acid protects the foetus from NTDs by at least 50%. Therefore, doctors recommend taking folic acid in the diet and in supplement form. If you already had a baby with NTD, folic acid supplementation reduces the risk of NTD in another pregnancy by 70%. Folic acid intake reduces the chances of the following:

Low weight at birth
Poor growth in the womb
Cleft palate and cleft lip
Prevents premature delivery
Reduces any pregnancy-related complications

What Can You Do if You Are Pregnant?

Eat a healthy diet rich in leafy greens, nuts, legumes, and oranges. Along with a healthy diet, you should also take a folic acid supplement at least a month before pregnancy and continue until 2 to 3 months after becoming pregnant. This significantly reduces the chances of NTDs. The recommended dose of folic acid is 400 mcg, but consult with your doctor before starting on any dose.

What Should You Do if You Already Had a Child with NTD?

If you already had a child with NTD, you must consult with your doctor about the supplements to be taken and the diet to be followed. The recommendation is to take 4000 mcg of folic acid daily, starting 1 month before becoming pregnant again until 3 months of pregnancy. However, this should only be taken after a doctor's consultation. If not planning a pregnancy, it is advised to take 400 mcg.

Food Containing Folic Acid

Beans
Fruits like oranges and melons
Nuts
Grains
Yolk of egg
Salad greens
Enriched cereals

You can either take a folic acid supplement, get it through a healthy diet or get it from a multivitamin. But you should know that appropriate dosing is important. If you take less than the required quantity, you will miss out on the advantage of this vitamin. If you take more than required, then it masks the deficiency of vitamin B12; this results in nerve damage. Your prenatal vitamin will have the required dose of folic acid, and your doctor will guide you in this process.
