Prenatal vitamins can be taken before conception, during pregnancy and at times, even after delivery. They contain the necessary vitamins and minerals that are needed during pregnancy and can be found over-the-counter or may be prescribed by your doctor.

Why You Need Prenatal Vitamins

In general, prenatal vitamins contain the vitamins and minerals that your body needs when you're pregnant. Your diet may not include enough of a certain nutrient and this is when prenatal vitamins are necessary. This is especially true for the following nutrients:

Folic Acid

According to current dietary guidelines a pregnant woman needs 600 mcg of folic acid which may be difficult to achieve with diet only. Folic acid is known to help reduce the risk of neural tube defects, which are birth defects of the brain and spine.

Iron

When you are pregnant, you need extra iron. This helps your body produce more blood that will ultimately provide oxygen to your baby. The recommended amount of iron is 27 mg when pregnant, which is nearly double the amount needed when you are not pregnant.

How They Work

While the best way to get your nutrients is by eating healthy, there may still be times when there are nutritional deficiencies in your diet. This is when prenatal vitamins are especially helpful. Prenatal vitamins are meant to supplement a healthy lifestyle and never meant to be a substitute for a good, well-balanced diet.

When an Additional Supplement May Be Needed

A healthy diet should provide you with the recommended amount of vitamins and minerals. However, there are times when you may need a supplement in addition to your prenatal vitamin. For example, omega-3 fatty acids that are found in fish are important to a baby's brain development. If you do not eat fish, you may need a fish oil supplement. Prior to taking any additional supplements, you should discuss this with your doctor.

What Is the Difference Between Prenatal and Regular Vitamins?

It is important to understand the difference between prenatal and regular multivitamins, their makeup, and what each are used for.

Prenatal Vitamins

Prenatal vitamins are specifically designed and formulated for women who are trying to conceive or are already pregnant. The nutrients in prenatal vitamins are essential to your health and your baby's growth and development.

Regular Multivitamins

Multivitamins are vitamins that are used by people of all ages for their overall, general health and well-being. While multivitamins are appropriate for most people, they do not contain the necessary nutrients needed for a woman during her pregnancy.

When Should You Take Prenatal Vitamins

You should actually take prenatal vitamins before, during and after pregnancy.

Before Conceiving

If you are planning for pregnancy, it is recommended that you start taking prenatal vitamins about three months prior to conception. This will help your body get ready for pregnancy and it will help reduce the risks of birth defects for your baby.

During Pregnancy

It is beneficial to consistently take your prenatal vitamins throughout your pregnancy. Not only will you and your baby receive the necessary nutrients needed during your pregnancy, it will also help ensure a healthy pregnancy for you and your baby.

After Delivery

It is recommended that you continue to take your prenatal vitamins until you stop breastfeeding. This will help maintain the necessary nutrients needed for the nutritional support of your growing baby.
