“Iron is the big one,” Kealy says. “With our menstrual cycle we have additional iron losses.” According to the NHS, iron deficiencies can lead to anemia, which can cause tiredness and shortness of breath among other symptoms, so it’s vital to stay on top of it.
Calcium is also important for female athletes, as well as vitamin D (although this one is important for all athletes). Kealy ideally recommends getting these through a nutrient-rich diet, which will cover all the nutrients your body needs.
For certain nutrients you may need to go down the supplement route. She suggests supplements of iron and folic acid—something that’s recommended for pregnant women but can also be helpful for athletes.
Kealy advises getting an annual blood test to check your iron and vitamin D levels, as well as B12.
