In episode 25, I tell the story of my personal story with iron overload, and weigh in on the proper use of blood tests and strategies to manage anemia, hemochromatosis, and everything in between. It's important to realize that these are the extremes, and there is a large middle space where we need to not only manage how much iron we accumulate, but how we direct it away from its disease-promoting roles and into its health-promoting roles.

This is a great primer on iron as well as a source of insights you may not have encountered elsewhere, such as the importance of oxidative stress as an independent regulator of ferritin, and the potential dangers of supplements designed to protect against oxidative stress like milk thistle, Protandim, sulforaphane, and green tea extract, for people at risk of anemia.
