Summary

In today's episode, we're going to drill down on one critical micronutrient that is essential to humans in the right dose, highly toxic in the wrong dose, and one that many runners are chronically deficient in and that is iron.

To help explain the unique role of iron in runners, I invited Dr Mike Zourdos and Dr Sara Mahoney on the Run to the Top.  Mike and Sara have studied the role of iron in marathon runners for both health and performance, and fun fact, Sara is Mike's endurance coach.

Mike is a Full Professor and the Associate Chair in the Department of Exercise Science and Health Promotion at Florida Atlantic University in Boca Raton, FL. Mike's research lab, the Muscle Physiology Laboratory, focuses on resistance and strength training, but more recently, he has begun to come over to the endurance side of sport with a little help from Sara.

Dr Sara Mahoney is the Chair of the Department of Exercise Science and Associate Professor at Bellarmine University in Louisville, KY.  Her research has been focused in the use of nutraceuticals and the use of nutrition in athletic performance, specifically endurance and ultra-endurance events.

We need a precise mixture of macro and

micro nutrients to not only be healthy but also to perform our best. You probably

know that the perfect runner recipe is not going to be the same as what a weightlifter needs.

But did you know that the micronutrients that a runner needs might also be different than what other endurance athletes like cyclists and

swimmers need. In today's episode we are going to drill down on just one

critical micronutrient that is essential to humans in the right dose,

highly toxic in the wrong dose, and one that many runners are chronically deficient

and a good portion of men are iron deficient as well.
