The Best Iron Supplements for Pregnancy (2020 Update)

When you’re growing another human, the last thing you need is an extra reason to feel sluggish and exhausted. During pregnancy, you are more likely to experience iron deficiency because your body needs twice the normal amount of iron while making extra blood for your baby.

Adding an iron supplement can help you reach that daily goal and keep you energized and healthy during your pregnancy.

We’ve carefully chosen products with minimal side effects because you don’t need one more symptom to Google in the middle of the night. Here are seven of the best iron supplements for pregnancy.

Why do I need iron?

Iron is a mineral that our bodies need to form red blood cells. It aids in the production of hemoglobin, which delivers oxygen from the lungs to the rest of your body (1). Getting enough iron during pregnancy is vital to you and your baby’s blood supply, as well as fetal brain development. Taking iron helps boost the production of hemoglobin in your red blood cells, reduces fatigue, and improves your immune system.

Not every woman needs an iron supplement during pregnancy, especially if your prenatal vitamin already contains iron. While anyone can become anemic, you are at a higher risk if you have had back-to-back pregnancies, have severe morning sickness, are pregnant with multiples, or are vegan or vegetarian. Your doctor will check your iron levels through blood tests to determine if your levels are too low.

What are the side effects of iron deficiency?

Iron deficiency can cause you to feel weak, dizzy, and very tired. While these may seem like pregnancy symptoms, extreme fatigue can indicate anemia. Pregnant women suffering from anemia report barely being able to get out of bed or sleeping 12 hours at night and still needing a nap. Anemia can also cause headaches, cravings for things that aren’t food (pica), and restless leg syndrome. In some cases, extremely low iron levels can contribute to low birth weight or premature birth.

How can I increase my iron levels during pregnancy?

Iron deficiency anemia is common in pregnancy, particularly in the second half, so it’s important that your doctor monitor your blood levels. You can increase your daily iron by eating iron-rich foods. This can be challenging, however, as many pregnant women experience nausea, vomiting, and heartburn, causing them to gravitate towards bland or starchy foods. Adding an iron supplement can help you increase your iron levels. Keep in mind that while your symptoms can improve within a week or two, it may take a few months for your body to begin storing enough iron for iron levels to rise.

The daily dose for adults is 15 ml and contains 25 mg of plant-based iron, as well as vitamin E, zinc, B12 (which has been known to help morning sickness), folic acid, vitamin C, and biotin. The vitamins help boost your hemoglobin production and absorb the iron more quickly.

Anemia is sometimes caused by a lack of folic acid and vitamin B-12, making this supplement a good choice for pregnancy (3).

There are 60 jellies in each bottle, and adults need to take two per day. These are a great option for anyone who has had trouble swallowing pills or liquid to up their iron levels.

Yum-V’s Complete Iron does not contain as much iron as some of the other brands, so it may be better for pregnant women who are looking for a vitamin with some iron but aren’t anemic.

No matter your dietary restriction, YumV’s has it covered: these are vegan, kosher, and free of nuts, gluten, gelatin, and GMOs. These iron-rich supplements help increase red blood cell production to boost your energy, support your immune system, and stay healthy throughout your pregnancy.

Is taking iron supplements during pregnancy safe?

Yes! The CDC recommends taking 30 mg a day starting with your first prenatal appointment. This amount may be adjusted if your iron levels are low. Talk to your doctor about his or her recommendation.

What should I look for in an iron supplement during pregnancy?

The last thing you want is to add to any existing nausea, constipation, or discomfort. Look for a supplement that is easy to take and doesn’t cause stomach troubles. The amount of iron you want in a supplement will depend on your current iron levels, whether you are anemic, and how many iron rich foods you typically eat.

What are iron-rich foods?

Poultry, meat, eggs, and plant-based foods like spinach, beans, tofu are all rich in iron. You can also find iron in cashews, dark chocolate, cereal, and oatmeal. Some foods that help iron absorption are beef and poultry, as well as those that contain vitamin C and vitamin A. On the other hand, taking your iron supplement with antacids, certain antibiotics, milk or dairy products, or caffeine may prevent proper absorption.

What is heme and non heme iron?

Heme iron is the most easily absorbed by your body and can be found in beef, turkey, pork, and chicken. If you are vegan or vegetarian, it’s even more important that you watch your iron levels. Non heme iron is found in spinach, beans, tofu, and cereal and oatmeal with added iron. These are not absorbed as easily but are still valuable and eating them along with vitamin C helps with absorption.

The Bottom Line

Our top pick is Vitron-C supplement (check price on Amazon), for packing a punch with a high dose of elemental iron and vitamin C to help with absorption. It’s easy on the stomach and the added benefits of the extra ingredients help keep you energized and healthy. You may need less iron in your diet or prefer taking a liquid supplement or gummies, but we’re confident that one of the supplements on our list will check your boxes. Making an extra blood supply is exhausting, which is why we’ve got your back.
