According to an article in The Washington Post, it's common for female athletes to have iron deficiency due to monthly blood loss and to diets that often don’t include fortified foods or red meat. It’s important to note that you can be iron deficient without being anaemic, although anaemia is often caused by low iron and refers specifically to low haemoglobin—the molecule that carries oxygen throughout the body. Lack of iron can lead to feeling tired, cold, and depressed, which can impact performance in a big way. Luckily iron deficiency is completely preventable. Here’s what you need to know:

• The National Institutes of Health’s recommended iron intake for premenopausal women is 18 mg daily. According to one expert, female athletes may need to take a higher dosage.
• Aside from red meat and seafood, green-leafy vegetables can also provide iron, especially when consumed along with vitamin C. Avoid eating these foods with ones that interfere with iron uptake, such as coffee and tea.
• Iron can be taken as a supplement, but it’s important to be screened first to see how deficient you are, as getting too much iron is not healthy.
