Sep 26, 2025

Join us in this insightful podcast episode where host Carol Petersen interviews Dr. Jeffrey Dach, a renowned expert in bioidentical hormones and natural thyroid treatments. Drawing from his extensive experience as a former interventional radiologist turned thyroid specialist, Dr. Dach shares his journey, the pitfalls of conventional thyroid care, and groundbreaking insights from his books, including “Natural Thyroid Toolkit: Hashimoto’s, Graves’, Iodine and Natural Desiccated Thyroid” and “Bioidentical Hormones 101.”

These books delve into topics like selenium’s role in thyroid health, the unreliability of TSH tests, the superiority of combination T3/T4 therapy, links between hypothyroidism and chronic diseases like kidney failure and dementia, and historical perspectives from pioneers like Broda Barnes. This is Part 1 of the discussion—perfect for anyone struggling with thyroid issues or seeking functional medicine approaches.
