Best Iron Supplements for Pregnancy Reviewed in 2018

You may have heard rumblings about iron deficiency during pregnancy and mild anemia in the early stages of your first trimester. By the time you’ve gone to your first prenatal appointment, it’s probably been pretty drilled into your head, and it’s definitely something that shouldn’t be put on the back-burner or left unaddressed. Many women do come down with some form of iron deficiency during their pregnancies which might seem odd because, by that point, you’ve stopped bleeding altogether. Mild anemia such as this can become prevalent because your baby is also using your blood supply in addition to all of the vitamins and nutrients that you take in. Vitamin deficiencies become a relatively big concern when it comes to early pregnancy because it’s true what they say… You are actually eating for two! This means twice the amount of vitamins, nutrients, and proper care.

While eating plenty of dark green leafy veggies and certain iron-rich meats (in moderation, of course) are helpful in the way of keeping your iron levels up, sometimes it’s just not enough. Iron supplements can be highly beneficial to pregnant women because they deliver everything you need for a day in one easy pill and can be taken in seconds. It’s easy enough to do and plenty of supplements also contain other vitamins that will help your body adjust to and be at its best during your pregnancy. We’ve found the best supplements out there for every need you might have while pregnant so that it’s one less thing to stress over. We’ve got you and your iron intake covered!

10 Best Iron Supplements for Pregnancy

1. MegaFood Blood Builder

First up on our list is one that’s absolutely perfect for pregnancy because not only does it contain iron, but it also contains folate, vitamin B12, and vitamin C. These are all essential and crucial to your pregnancy, since they all help your baby to develop and support significant immune health for both of you.

These pills contain 26 mg of daily iron which is just under the recommended dose for women while they’re pregnant, and since it does contain other vitamins, this is a great daily pill to take. This pill could also be taken continuously after you give birth and especially while you’re still bleeding postpartum because it’ll keep your natural iron levels up and steady throughout. The Blood Builder pill makes good use of beets, oranges, and broccoli in order to provide one full dose per day which makes it a great natural option as well.

The oranges and beets used in this formula help to aid in iron absorption which is key while you’re pregnant. It’s gentle, effective, and safe for women, teens, and anyone who’s vegetarian or vegan.

What We Like About It
The look of this pill is less clinical and more all-natural and user-friendly. It looks like something that’s derived from all the fruits and veggies that are in it which is very reassuring to someone who has never taken iron supplements before.

2. Solgar 180 Vegetable Capsules

Another vegetarian and vegan-friendly option for iron are the Solgar Gentle Iron pills. These pills don’t contain anything but iron which can be a good thing if you’re also taking prenatal pills or a multivitamin, but if you are looking for an all in one pill, this one doesn’t fit that category.
Expand to see more
However, it does have a bunch of other benefits including the fact that there are 180 pills in one jar which, for the price, is a ridiculously great deal. That allows you to continue taking this pills after pregnancy and eliminates the need for you to constantly refill your medicine cabinet. Solgar iron is also extremely gentle on your stomach because, as you can probably imagine, taking iron supplements can sometimes cause discomfort. These pills have been designed to be gentle and won’t upset your stomach… A definite plus if you’re taking them while you’re pregnant!

The iron in these pills is derived directly from vegetables so it’s safe for use if you don’t eat meat. As an added bonus, it won’t cause an upset stomach, which can help tremendously if you’re struggling with morning sickness.

What We Like About It
The amount in direct relation to the price you pay is totally something we can get behind. Sometimes the cost does make a difference, and when you’re pregnant it’s just one less thing to stress over.

3. Vitron-C High Potency

This iron supplement is called “high potency” for a reason. It’s designed to be taken by those who do have vitamin deficiencies and since that’s a very common occurrence during pregnancy, it made the list as a good option for moms-to-be who need a little extra.
Expand to see more
The daily dose for this iron pill is 65 mg which is roughly three times the recommended amount for women who aren’t pregnant, and two and a half times the amount for women who are. The Vitron-C supplements also include an extra dose of vitamin C which will work hand in hand with iron to aid in absorption and keep your immune system strong. This is the perfect pill for those who need a higher than average dose of iron and want to ensure that they have a strong immune system throughout their pregnancy as well.

These pills are easy on your stomach which is a great plus, but they also help to give you a much-needed boost of energy while you’re pregnant. Energy can often be in short supply when you’re feeling off, but the powerful combination of iron and vitamin C can be extremely helpful to ward that off.

It’s formulated to have the highest absorption rate possible and is also super gentle on your stomach, which we know is music to the ears of pregnant women everywhere.

Expand to see more
In short, that means nothing has been altered before going into the pills and they also contain live probiotics and enzymes that can help your overall digestive health.

Expand to see more
These tables are designed to melt as quickly as possible, leaving you with no weird flavor or taste in your mouth.

You can take them on the go or after a meal easily and won’t have to worry about having water on hand or dry swallowing an awkward pill.

Despite its “zesty orange” flavor, these meltable supplements are sugar-free. Since sugar can cause its own problems, the fact that these are flavored and go down easily is truly remarkable.

What We Like About It
Taking iron doesn’t get any simpler than this and you can take more than one (as directed by a professional) if you are deficient or pregnant and in need of twice the daily dose. They’re great to have on hand and a good way to get your iron if you’re just not about that supplement life.

7. Feosol Original 120 Count

There’s a bit of confusion that happens here because of the fact that these pills use ferrous sulfate, which appears to be a ton of iron in one pill. This isn’t the case, as the amount in each dose of ferrous sulfate is equivalent to 65 mg of elemental (natural) iron.
Expand to see more
So don’t worry, you’re not taking a massive influx of daily iron -- You’re just taking it in a different form that equates to two and a half times the normal amount during pregnancy. These pills are designed for women who are anemic and need that extra dose daily. Since there’s nothing in this supplement besides iron, you could potentially take it in addition to your prenatal vitamins if your doctor approves it. This is pure iron, plain and simple, for when you need more of it than usual.

Feosol iron is specifically recommended by physicians which is a huge relief to women who might be a little wary of taking it for the first time. It’s great to keep your iron levels up and does so quickly and efficiently.

Expand to see more
These pills are super easy on your stomach and won’t cause constipation or stomach aches. They come in a capsule form which makes them much easier to take for those who can’t stand the idea of swallowing regular coated pills.

Criteria Used in Evaluating the Best Iron Supplements for Women

We can’t stress how important it is that you’re in tune with your body and what it truly needs while you’re pregnant. Something as simple as a daily iron supplement could mean the difference between a healthy and happy pregnancy, or one that requires a little extra work and won’t have you feeling your absolute best. The CDC recommends taking iron by the time of your first prenatal appointment, at least the lowest dose you can to start — This is roughly 30 mg to start. Throughout your pregnancy, you need at least 27 mg every single day in order to keep your iron levels up to a sufficient amount for you and your baby. This is why iron supplements are such a great investment because they’ll last the entirety of your pregnancy and for some time after, which we’ll get to in just a minute.

It can be a bit intimidating initially trying to figure out your recommended dose and how much will do you, especially while you’re pregnant. The good thing about iron supplements is that they can continuously be taken postpartum as well since you’ll likely be losing blood for six to eight weeks afterward. Your pregnancy as a whole is a time when you need to increase all of your vitamin and mineral intakes, but many people don’t realize that it’s important after you give birth as well. That’s why half of this list contains iron supplements that are great for average daily doses as well (18-26 mg) since you’ll need it while you’re breastfeeding and, overall, recovering from your pregnancy. We created this list to be as comprehensive as possible when it comes to knowing exactly what you need, what works, and what doesn’t. As always, you should consult a doctor before you start any type of permanent iron supplement routine, but all the options that made our list have been certified, tested, and have a reputation for effectiveness.

Additional Factors to Consider:

Can You Take More Than Your Recommended Amount?

It’s never a good idea to take more supplements than what’s considered to be “average” unless otherwise directed by your doctor. In some cases, he or she might go ahead and give you the green light to increase your dosage based on your eating habits and current or future iron levels. On the other hand, you might be perfectly fine as far as existing levels go and might just need that extra supplement. Either way, talking to your doctor is always your best bet as far as how much to take and when. Many of the supplements on here are sufficient for women who are anemic as well as suffering from an iron deficiency while pregnant; we’d say roughly half our list is dedicated to those in those circumstances. This simply means that different pills have various levels of iron in them and you’ll just need to speak to your doctor to figure out the appropriate daily dose for you depending on your iron levels.

How Does Your Diet Affect Iron Levels?

Your diet and eating habits while pregnant are extremely important when it comes to vitamin levels. Women are mostly deficient in iron and magnesium because they’re just not something many of us get on the regular. While you’re pregnant, you’re in need of these even more, which can lead to deficiencies. It’s a scary word but can be fixed relatively easily with the addition of supplements to your diet. If you’re vegetarian or vegan, you might notice that you need a bit more iron simply because you don’t eat iron-rich meats. This is perfectly fine, though… That’s why these iron pills exist! Some of the supplements on our list even contain additional vitamins that can be helpful in the way of immune support, which is a great addition to your daily prenatal regimen.

How Do You Know If You’re Deficient?

While some women may not even realize that their iron levels are low, others can sense it almost immediately. The depletion of iron can leave you feeling extremely tired and fatigued, which can sometimes be challenging to differentiate when it comes to common pregnancy symptoms, especially in the first trimester. In addition to fatigue, you might get random dizzy spells and feel faint, which is a definite sign that something isn’t right. Pregnancy might drain you a bit and leave you feeling much more tired than usual, but if you ever feel on the verge of passing out, contact your doctor ASAP. Another symptom of an iron deficiency or anemia can include insomnia which is sudden and onset, which you should also consult your doctor about. Iron deficiencies are simple to fix and your doctor will be able to prescribe you a recommended dosage, which can then be used when finding one from our list.

How And When Should You Take Iron Supplements?

This is a big one, and it’s also very important to make note of and be aware. Similar to eating or drinking anything after taking any type of zinc supplements, iron supplements need to be spaced out in your diet. It’s recommended to not take anything within two hours or so of taking iron supplements due to their absorption and the way they’re processed in your body. So while it’s a good idea to take them in the morning so you don’t forget accidentally, you could also take them at night before you go to sleep if your space your meal out appropriately. The tricky thing about iron is that it can sometimes cause an upset stomach as well. This is obviously not something that you want to deal with while pregnant and already possibly dealing with morning sickness, so for the sake of that, we’ve included as many supplements as we could that prevent that “sick” feeling from taking them. It can be extremely helpful to take these supplements as well after you eat since you’ll have something in your stomach to aid with absorption and help pad the incoming iron a bit but, of course, you should always consult your doctor for additional information.

Who Is At The Greatest Risk?

Any mom-to-be can suffer from an iron deficiency, it’s just all dependent on her diet and natural iron levels. However, you might be at a much greater risk if you are carrying twins or multiples, as this will take much more away from your natural vitamin intake. While you might feel the effects of too little iron, it’s very possible for your baby to as well. Iron is essential and crucial to their development due to the fact that it’s responsible for producing hemoglobin, encouraging healthy blood cells, and it’s highly beneficial to overall immune health. For nine months, you and your baby are essentially one person which is why it’s so important to ensure that you’re both getting exactly what you need.

Iron After Pregnancy

Yes, it’s important to continue keeping your iron levels up after you give birth. This is important for a multitude of reasons, the first being how much blood is lost during pregnancy. It’s perfectly normal for you to feel faint and lightheaded right after, but your iron levels need to stay up in order for you to recover quickly. Once you’re home and in full recovery and mom mode, iron still serves a purpose: Breastfeeding. The CDC recommends a constant level of at least 18 mg/day while you’re breastfeeding because not only will you need it, but your baby is still getting their nutrients from you. It might seem like a lot, but in the end, it’s all worth it in order for you and your baby to be super healthy.


Frequently Asked Questions

Q: Is it possible to take too much iron?

A: Yes, it is absolutely possible to increase your intake by too much. While you do need a high dose while pregnant, always check with your doctor before upping your daily intake on your own.

Q: Can these be taken in addition to prenatal vitamins?

A: That’s another thing you’ll want to check with your doctor on. Many prenatal vitamins will already have a certain amount of iron in them, however, if you are deficient, additional supplements will most likely be required.

Q: Is it safe to take these before I have my prenatal appointment?

A: If your pregnancy has been confirmed, then yes — The CDC recommends that every woman should be taking iron by her first official prenatal appointment. When you get there, discuss a future course of action for supplements.

Q: Do I need to take vitamins that have extras such as vitamin C in them?

A: While this is not necessary, it can really be helpful to keep both yours and your baby’s immune system healthy and working well. Vitamin C is one of the essential vitamins needed during pregnancy, so it can’t hurt any.

Q: Is it best to take these in the morning or at night?

A: That’s up to you, however, it is best to take them with food — We recommend first thing in the morning after you eat so that a) you don’t forget to take them, and b) it’ll be more of a “morning routine” when you eat breakfast.

Q: Is any one of these better than the other in terms of quality?

A: No. Each one of these iron supplements has been chosen because of dosage (we’ve tried to have varying levels for different situations), additional added vitamins, and how helpful it is throughout pregnancy.
