Why prenatal vitamins are important
According to Dr Sadhna Singhal Vishnoi, Senior Consultant, Obstetrics and Gynecology, Cloudnine Group of Hospitals, New Delhi, Punjabi Bagh (India), prenatal vitamins play an important role in supporting the development of the fetus and maintaining the health of the mother throughout pregnancy. Here are the important nutritional elements that prenatal vitamins provide:
Preventing neural tube defects: Neural tube defects (NTDs) such as spina bifida can occur very early in pregnancy, before a woman even knows she is pregnant. Folic acid, a B vitamin, helps prevent these defects. Taking 400-800 micrograms of folic acid daily, especially starting a month before conception, is important for the development of the neural tube, which forms the baby’s brain and spinal cord.
Supporting fetal development: Prenatal vitamins provide essential nutrients to help develop your baby's organs, bones and tissues, while helping the mother maintain healthy energy levels, prevent anemia and support a healthy pregnancy.
In addition to folic acid, other vitamins and minerals such as iron, calcium, iodine and DHA also play an important role in maintaining the health of both mother and baby.
Key nutrients in prenatal vitamins
Dr Sadhna Singhal Vishnoi says that key nutrients during pregnancy play specific roles in supporting the development of the fetus and protecting the health of the mother. Here are some of the most important:
Folic acid: Helps with cell division and formation of the fetal neural tube. Folic acid supplementation should begin during the first trimester and may continue throughout pregnancy.
Iron: Iron needs increase during pregnancy to prevent anemia. Prenatal vitamins typically contain about 27 milligrams of iron, which helps fight fatigue and reduces the risk of complications.
Calcium: Important for the development of the baby's bones and teeth, and also prevents bone loss in the mother. In addition to vitamin supplements, the mother needs to supplement calcium from foods such as milk and green leafy vegetables.
Iodine: Important for thyroid function and cognitive development of the fetus. Iodine deficiency can lead to developmental delays. Prenatal vitamins often contain iodine, which is especially important for vegetarians or vegans.
DHA (Docosahexaenoic Acid): Omega-3 fatty acids help develop your baby's brain and eyes. DHA can be supplemented alone or through foods such as fatty fish.
When to start taking prenatal vitamins
The timing of prenatal vitamin supplementation is important. Women should begin taking prenatal vitamins at least three months before conception to ensure adequate intake of nutrients, especially folic acid, to support early fetal development.
“Starting prenatal vitamins before conception and continuing throughout pregnancy will help prepare the mother’s body for the baby’s development,” advises Dr. Vishnoi. “For women who have conceived, it is important to start taking vitamins immediately.”
