Most people think iron is only a concern if they're deficient, but too much iron can be just as dangerous. In this episode, I sit down with Dr. Christy Sutton, a leading figure in the study of iron imbalances, to explore the often-overlooked health epidemic of unrecognized iron overload. Anchored around her book, The Iron Curse, we discuss why outdated laboratory ranges often fail to detect these imbalances and why recognizing them is so crucial for long-term health.


From there, we dive into the intricacies of iron metabolism and the need for updated functional health ranges tailored to healthy populations. Dr. Sutton explains how imbalances can signal underlying health problems and highlights the value of functional lab testing in catching issues conventional methods often miss. We also explore the role of genetic testing—especially for hereditary hemochromatosis—and how genetics and environmental factors work together to influence iron levels.

Key Takeaways:

  • Iron Imbalance Epidemic: Iron imbalances, particularly overload, are often underdiagnosed due to outdated lab ranges and misconceptions, representing a silent health epidemic.

  • Functional vs. Conventional Ranges: Functional health ranges, as opposed to traditional lab ranges based on sick populations, are crucial for accurate diagnosis of iron-related health conditions.

  • Importance of Genetic Testing: Genetic factors (hemochromatosis genes) play a significant role in iron overload, necessitating comprehensive testing beyond typical lab work.

  • Dietary and Lifestyle Influences: Both high and low iron levels are influenced by diet, lifestyle, and, importantly, how iron interacts with other nutrients and lifestyle factors like exercise.

  • Gender and Iron Requirements: Iron needs differ significantly by sex and life stages, with menstrual and post-menopausal women, as well as men, needing tailored iron management strategies.

More About Dr. Christy Sutton, D.C.:

Dr. Christy Sutton is interested in asking why health problems happen and finding the safest and least problematic solutions. Her work takes a deep and meaningful dive into genomics, labs testing and creating a personalized health plan.

Her focus on finding and avoiding health landmines early stems from her personal experience with Crohn's and celiac disease plus her husband's experience with high iron, hemochromatosis, and a pituitary tumor that likely was associated with having undiagnosed hemochromatosis.
