The Importance of Iron During Pregnancy
Iron is a mineral that our bodies need to stay healthy. The red blood cells contain most of the iron in our body, in a pigment called hemoglobin. Hemoglobin is responsible for carrying oxygen around our body to the cells, organs, and tissues where it’s needed.
When iron levels are low, so are the levels of hemoglobin. This is bad news as it reduces the oxygen supply. Anemia is the name given to low hemoglobin levels.
The normal levels during the first and last trimester of pregnancy are considered to be above 11 grams per deciliter. This changes during the second trimester, when they can be a bit lower, at 10.5 grams per deciliter.
You might feel a bit like a pin cushion during pregnancy, having samples taken all the time. It is necessary, though, to make sure all is well. One of the things checked during blood tests is your iron levels.
Doctors will also check how much iron your body has stored. Yes, it can retain a certain amount of iron for when it’s needed. If you have depleted your stores and your hemoglobin levels are low, you’ll need iron supplements (1).
In addition to supplying nutrients for two, you are also supplying blood to two when you’re pregnant, so your blood supply increases. You will need about double the amount of iron than you do normally, which is about 27 milligrams per day.
If you’re deficient in iron, you can start to feel tired, weak, and dizzy. Your pregnancy glow can wane and you will look pale and probably find yourself breathless. On top of all your other pregnancy symptoms, this is no walk in the park (2).
Cooking some of your food in an old-fashioned iron skillet will leach iron into your meals, thus increasing your iron stores.
How to Choose an Iron Supplement
Narrowing down the ingredients that will benefit you can help you make an informed decision when choosing an iron supplement. Here are some of the things you should look for.
The Amount of Iron
We have mentioned that during pregnancy you should have 27 milligrams of iron a day. Remember, this won’t only come from the supplement — your body will absorb some from food as well. Consequently, a lower dose in a supplement is fine, as long as you’re also getting iron from your diet (3).
Many iron supplements will also contain vitamin C and other vitamins, like B12 and folates (vitamin B9). The vitamin C will help absorption of the iron while the B vitamins help prevent birth defects, like spina bifida and central nervous system disorders. Folates also help with the production of red blood cells, helping prevent anemia.
Tablet, Capsule, or Liquid
Iron supplements often have a metallic taste and some tablets and capsules can be large. If you find you can’t swallow what looks like a horse pill, then there are liquids and chewable tablets available.
Different Types of Iron
In supplements, you’ll find various iron sources such as elemental iron, ferrous fumarate, and ferrous sulfate, to name a few. You might find one type suits you better than another – if the one you choose gives you lots of side effects then change to a different type. Your healthcare provider should be able to advise you as to which type of iron you need.

Foods That Increase Iron Levels
Many foods contain iron and they can boost your levels. This is by far the best way to get that essential mineral into your body.
Some iron comes from animals and others from plants. While both contain iron, it’s not the same type.
Animal sources contain heme iron that is absorbed easier than that which comes from plants, called non-heme iron. Foods which are rich in iron include (7):
- Meat, including beef, turkey, lamb, chicken, pork, and veal.
- Seafood, including mackerel, haddock, sardines, and shrimp.
- Shellfish, like clams, scallops, and oysters.
Avoid raw or unpasteurized eggs as well as limiting mercury-containing fish.
- Vegetables, including spinach, kale, collard greens, broccoli, string beans, and peas.
- Bread, including whole wheat, rye, and enriched white.
- Cereals, like bran and oats.
- Beans, including kidney, white beans, and dried varieties.
- Lentils and dried peas.
- Corn and maple syrups and molasses.
- Tomato products.
- Fruits, including dates, strawberries, figs, prunes, and watermelon.
- Dried fruits, like apricots and peaches.
- Peanut butter.
Iron is absorbed better by our body when it’s accompanied by vitamin C. So help yourself to a nice chilled glass of orange juice with your iron-rich foods. If you’re having cereal, chop up some fresh strawberries in it (8).
Tea and coffee, as well as caffeinated drinks, are not your friend when it comes to iron absorption. It reduces the uptake of iron from your food, or a supplement. If you must have your daily caffeine fix, then make sure it’s a few hours after taking an iron supplement or iron-rich meal (9).
Another thing that can interfere with the absorption of iron is calcium. Make sure you don’t take a calcium supplement at the same time as an iron one. Also, avoid milk and other dairy products for an hour before and two hours after taking your iron boost (10).
Side Effects of Iron Supplements
Some of the common side effects associated with iron supplements include constipation, nausea, vomiting, and diarrhea. I know, you already have enough to contend with when you’re pregnant without adding more to the mix.
If they make you feel sick, try not to take them on an empty stomach. You can keep constipation at bay by increasing your fluid and fiber intake.
If any side effects are bothersome, then speak to your healthcare provider for advice and support (11).
