Do Prenatal Vitamins Really Work?
August 26, 2008
Prenatal vitamins have become very popular among some women because it is believed that they help prevent birth defects. It is probably a good idea to supplement with prenatal vitamins because during pregnancy, both the mother and the child have increased needs for certain nutrients like folic acid and iron during this time and prenatal vitamins will prove helpful. Women who are pregnant often find that their doctors prescribe a prenatal vitamin. However, evidence has emerged that even for those women that are planning to conceive can benefit from prenatal vitamins. Prenatal vitamins could prevent potential nutritional deficiencies during this crucial time.
Most of the prenatal vitamins currently available are meant to make-up for possible nutritional failings. They almost always include such nutrients as folic acid, calcium, and iron. These nutrients lessen the likelihood of birth defects caused by nutritional deficiencies.
IMPORTANT NUTRIENTS FOR MOTHER AND CHILD:
DHA
DHA is a fatty acid that is crucial for baby’s brain development from the earliest stages of pregnancy through the breast feeding years. DHA is a type of essential polyunsaturated fatty acids belonging to omega 3 families. There are two types of essential fatty acids - omega 3 and omega 6 families. DHA is an omega-3 fatty acid that appears to be important for brain, eye, and heart health. The typical American diet is usually deficient in DHA.
IRON
Iron is a mineral and is another important nutrient in pregnancy. Most prenatal supplements will include iron in their mixture. During the third and final trimester of pregnancy the baby will draw large amounts of iron from the mother. It will obtain this iron from the stored levels in the mother’s body.
FOLIC ACID
Folic Acid is very essential for a healthy pregnancy and healthy fetal development. It has been shown to decrease the risk of birth defects like spine bifida or other neural tube defects. Folic acid is naturally found in dark, leafy vegetables, citrus fruits, dried beans, and whole grain breads and cereals. Most cereals are also fortified with many other vitamins and can be a good dietary choice for the pregnant woman who cannot tolerate vitamins. Folic acid is an essential nutrient that can help prevent birth defects in newborns.
Folic acid has been proven essential to a baby’s neural tube development during the first three months of a woman’s pregnancy. This is the time when the mother is most likely to experience nausea and vomiting. Folic acid is regarded as so important that it is often recommended that women start taking folate, 30 days or more prior to attempting to conceive.
CALCIUM
Calcium is extremely important as well as essential to both the mother and child in pregnancy. Calcium and magnesium help protect the mother’s bones during this time when the demands of both her body as well as the baby’s body for these nutrients must be met. A good prenatal vitamin will contain calcium, but the mother must also eat a well balanced diet to obtain calcium as well.
Finally, not all prenatal vitamins are created equal… While most prenatal vitamins try to pack in as much as they can into the vitamin, they must be careful not to promote an excess of potentially toxic fat soluble vitamins. Vitamin A should be provided as water-soluble beta carotene at a level that won’t cause vitamin A toxicity. Vitamin E should be included from an all-natural source and provided in a safe amount. Deficiencies in vitamin E in pregnancy have been linked to birth defects so having “just enough” is important. Vitamin K, another fat-soluble vitamin, which also needs to be provided in amounts that avoid toxicity.
