McKale is a dietician, runner, and has a big passion for iron. Iron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen to the body. Today, McKale talks about the role of iron, why it is important for runners and what you should do if deficient. Throughout the interview, Mckale talks about: Is a drop in energy levels during certain parts of the menstrual cycle caused by low iron? Does a runner require a diet higher in iron? Are infusions and supplements necessary? And are there any dangers? Check out McKale on Twitter @McKaleDavis Or ask her a question at [email protected] Run Smarter YOUTUBE Channel Become a patron!
