Prenatal Vitamins: Why You Need And How To Choose Them?


During pregnancy, your body will require more of everything to support the growing fetus: more calories, vitamins, minerals, and essential fats.

Following a healthy diet is, therefore, essential to ensure that you get the required nutrients every day. But sometimes, diet alone will not suffice. In such cases, doctors prescribe prenatal vitamins if you are pregnant or want to get pregnant.

While prenatal vitamins are available as over-the-counter (OTC) supplements, it is best to check with your doctor before taking them. In this MomJunction post, we tell you what prenatal vitamins are, how to choose them, and how long you should take them. As a bonus, we have also listed the ten best prenatal vitamins you may take after consulting your doctor.

What Are Prenatal Vitamins?

Prenatal supplements or prenatal multivitamins are the essential vitamins and minerals that your body requires to sustain a healthy pregnancy. Doctors prescribe these vitamins for women who need adequate nutrition during pregnancy, lactation, and pre-conception(1). Some of the essential vitamins and minerals are folic acid, calcium, iron, vitamins A, B, C, D, magnesium, zinc, thiamine, and iodine.

When Should A Pregnant Woman Start Taking Prenatal Vitamins?

Ideally, you should start taking prenatal vitamins a month before you plan to get pregnant. You can continue through your pregnancy and after delivery, as long as you are nursing. Taking these supplements before conception helps your body to meet the nutrients requirements to carry on with a successful pregnancy. Also, prenatal supplements can reduce the risk of a few birth defects.

How To Choose The Best Prenatal Vitamins?

Most supermarkets and online stores stock on OTC prenatal vitamins. But how would you know which ones are good for you? Here are a few ways to determine that.

1. Check for approvals: FDA does not regulate the production of these supplements. To assess the ingredients, the presence of harmful substances, and to know if they are safely manufactured, you need to check the symbols of approval from independent organizations.

Some commonly known regulatory bodies include NSF International,, and U.S. Pharmacopeia. However, understand that these seals do not guarantee the effectiveness or safety of the multivitamins (2).

2. Check the daily value of nutrients: The recommended dietary allowances per day for pregnant women are mentioned here. You may consider these while buying prenatal vitamins (1) (3).

Nutrients Value per day
Iron (mg) 27
Calcium(mg) 1000
Zinc (mg) 11
Phosphorus (mg) 700
Folate (μg) 600
Vitamin A (μg) 770
Vitamin C (mg) 85
Vitamin D (μg) 15
Vitamin E (μg) 15
Vitamin K (μg) 90
Vitamin B9/ Folic acid (mcg) 400
Folate (μg) 600
Selenium  (μg) 60

3. Check the brand name: Do not pick up just any prenatal vitamins bottle with attractive packaging or no seals. Look for reliable brand names that can be trusted for quality and safety.

4. Talk to the professional: When in doubt, talk to your doctor about when to take the prenatal vitamins, what the right dosage is, and which brand to choose. Based on your health condition, he or she would recommend the best options for you.

What Is The Difference Between A Prenatal Vitamin And A Regular Vitamin?

The regular multivitamin supplements help you meet your daily nutritional requirements when you are not pregnant. However, during pregnancy, you need more vitamins and minerals than usual to support yourself and your baby. Prenatal vitamins are formulated to provide extra nutrition for women who are trying to conceive or are pregnant.

These supplements contain more iron and folic acid to reduce the risk of low birth weight, preterm labor, infant mortality, anemia and congenital disabilities (4) (5).

How Long Should You Take Prenatal Vitamins After Delivery?

You can continue taking prenatal vitamins throughout your pregnancy and also when you are breastfeeding your baby. However, read the labels carefully because some are meant only for pregnancy while some can be taken during pre-conception, pregnancy, and lactation.

Some prenatal vitamins may make you nauseous while others could upset your tummy. This could be due to the excess iron that these supplements pump into your body. While it is not a major problem to worry about, you may consult your doctor to stay safe. In any case, check with the doctor before you start taking a prenatal supplement.
