As this low level of iron is so prevalent in runners, it should not be one of the things keeping you from putting on your shoes each day. If you are experiencing abnormal exhaustion, increased blood lactate or any of the things mentioned above, get yourself checked out. There are already enough excuses out there to keep you from running.
Don’t add this to the list.
EDITOR’S NOTE: Many non-meat source of iron are available, including beans and lentils, green leafy vegetables like broccoli and kale, chickpeas, lack-eyed peas, tofu, and fortified breads and cereals.
