When it comes to figuring out what foods are high in iron, and how to make sure you’re getting enough, simplify. If you eat meat, most women should consume 18 milligrams of iron per day between ages 19 and 50; pregnant woman and endurance athletes need more, and vegans or vegetarians need about 36 milligrams. But rather than counting milligrams, sports dietitian Rebecca McConville, MS, RD, simplifies by recommending two to three servings of iron-rich foods per day from animal sources, or three to five from plants. Add one extra the week before and during your period.

Do I Need an Iron Supplement?

For many athletes, the answer is yes. Marathoner Starla Garcia says more than three-fourths of her female training partners have needed a supplement, especially when they’re ramping up mileage.

There are many different types of supplements and doses, some of which are more easily absorbed than others. A dietitian or physician can recommend the best option and work with you to minimize side effects, such as nausea and constipation.

Individualized advice is especially important if you have other health problems or take prescription medicines, McConville says. Iron can interact with thyroid treatments, proton pump inhibitors for reflux disease, and other drugs.
