"I've heard there's a link between iron and fertility. Should I take iron supplements when trying to get pregnant or just make sure to get iron in my diet?"

You’re smart to be thinking about pumping up your iron levels while trying to conceive. As you’ve heard, there does seem to be a link between iron and fertility. In one study, researchers found that women who took iron supplements had a significantly lower risk of ovulatory infertility (an inability to produce healthy baby-making eggs) than those who didn't supplement.

Here's what you need to know about iron and fertility if you're trying to get pregnant.

Key Takeaways
  1. You need iron, but maybe not extra. Iron in your system is key when you’re TTC as it may lower the risk of ovulatory infertility — but not everyone needs a supplement.
  2. Your doc is your go-to. A quick blood draw can check your iron levels and then you’ll know whether you need more than what’s found in your prenatal vitamins.
  3. Nosh with iron in mind. Certain foods with iron like salmon, lentils, and spinach are smart to include, especially when eaten with things high in vitamin C (better absorption!)

Do you need an iron supplement if you're trying to conceive?

Before you rush out to buy iron supplements, keep the following in mind:

  • Not all women need supplements (but they do need iron). Experts say more research is needed before they’d recommend iron supplements to all women as a fertility booster. But even if iron isn’t recommended for you specifically, you’ll still want to beef up your iron stores the natural way before you get pregnant. Iron is one of the minerals that your future baby-to-be will siphon from you — and too little iron at the start of pregnancy can put you at risk for anemia during pregnancy and afterward (when you need all the energy you can get to take care of your baby).
  • Talk to your doctor. Your best bet when it comes to thinking about iron, fertility, and pregnancy? Discuss your nutrition with your practitioner and ask to get a blood test that will check your iron levels. If your test results indicate that you could use iron supplements, you and your doctor can work together to determine an appropriate dose for you. If your iron levels are healthy, then you may not need a separate iron supplement, but you’ll still want to make sure you take a prenatal vitamin every day (most of which include about 27 mg of iron).
  • Eat iron-rich foods. Every day, pregnant women need to aim for about 27 mg of iron. The most easily absorbed iron — called heme iron — is found in animal sources, such as meat, poultry, and fish. The other form of iron — called non-heme iron — comes from plant sources. However because of its chemical structure, it's more difficult for the intestines to absorb. But don’t disregard non-heme iron — it’s still worth your while. In fact, heme iron helps improve the absorption of non-heme iron, so eating food sources of both forms of iron at the same time is ideal.

Best iron-rich foods for fertility

The easiest way to get as much bang for your nutrition buck when eating iron-rich foods? Pair them with foods rich in vitamin C, which boosts iron absorption. So go ahead and top that burger with a tomato slice or two, sprinkle strawberries in your oatmeal, and follow that PB&J sandwich with an OJ chaser.
