Pregnancy Home > PreNexa Uses

PreNexa is a product that provides additional nutrition to pregnant women. The prenatal vitamin contains numerous vitamins, minerals, and fatty acids; these nutrients are important for a healthy pregnancy. Although there are currently no approved uses for PreNexa for children, men, or the elderly, the supplement may sometimes be prescribed in place of regular vitamins in order to get them covered by insurance.

What Is PreNexa Used For?

PreNexa® is a prescription prenatal vitamin. Prenatal vitamins are designed with pregnant and breastfeeding women in mind. They are used to fill in any nutritional gaps in the diet of pregnant and breastfeeding women. Even women who usually eat well-balanced and nutritional diets before pregnancy may have problems getting all the nutrition they need during pregnancy, due to morning sickness or other problems. Additionally, pregnancy and breastfeeding are times of increased nutritional need.
PreNexa is also useful for women who are trying to conceive. Because it is important to get enough folic acid prior to pregnancy and during early pregnancy (including the early weeks before you even know you are pregnant), your healthcare provider may recommend that you take a prenatal vitamin while trying to get pregnant.

In fact, since so many pregnancies are unplanned, it is a good idea for any sexually active woman of reproductive age to take a prenatal vitamin (or at least a multivitamin with a minimum 400 mcg of folic acid).

How Does PreNexa Work?

PreNexa contains a variety of different vitamins, minerals, and fatty acids. These nutrients are important for a healthy pregnancy, and many pregnant women may not get enough of these nutrients, for various reasons. Probably most importantly, this prenatal vitamin contains folic acid, which is important to prevent certain birth defects, such as spina bifida. It also contains iron, calcium, and various other vitamins and minerals.
PreNexa also contains docusate sodium, a stool softener that can help relieve constipation, a common problem during pregnancy (that can be made worse by the iron and calcium in prenatal vitamins).
Like many of the newer prenatal vitamins, this product contains the omega-3 fatty acid docosahexaenoic acid (DHA). There is some evidence that DHA may provide a variety of different health benefits, including a decreased risk of preterm birth (having a baby prematurely), improved brain function, and improved vision in the baby.
Fish are the main source of DHA, and the typical American diet is usually deficient in DHA. Additionally, since many pregnant women are instructed to limit their intake of certain fish (due to risks of mercury toxicity), it is likely that many pregnant women are not getting enough DHA. The DHA in PreNexa comes from a plant-based source.
