Prenatal vitamins are vitamin and mineral supplements intended to be taken before and during pregnancy and during postnatal lactation. Although not intended to replace a healthy diet, prenatal vitamins provide women of child bearing age with nutrients recognized by the various health organizations including the American Dietetic Association as helpful for a healthy pregnancy outcome. Prenatal vitamins are similar to other multivitamins, but do contain different amounts of specific nutrients to better suit the needs of an expecting mother. Vitamins and minerals such as folic acid, calcium and iron are in higher concentrations while nutrients such as Vitamin A are reduced to reflect the current understanding of the role that these compounds play in fetal development.
The increased dosage of folic acid or folates reflects the American Dietetic Associations position that women should consume “400 μg per day of synthetic folic acid from fortified foods (cereals and other grains), supplements or both, in addition to consuming folate from foods in a varied diet.” Often prenatal vitamins also have a reduced dosage of vitamins that may be detrimental to the fetus when taken in high doses (such as Vitamin A). Prenatal vitamins
are available both over the counter in retail stores as well as by prescription from medical professionals. Although prescription vitamins are often covered by insurance, the relative potency of prescription-grade products are typically not significantly different from those available through retail. Differences in prescription versus retail vitamins do however exist in consistency and quality level, as well as the relative bioavailability of some specific ingredients. For example, many prescription prenatal vitamins will contain a more bioavailable form of folate; 5-methyltetrahydrofolate (5-MTHF).FULL ARTICLE
