Thyroid Nodules, Iron Toxicity & The Copper Connection w/ Morley Robbins

What if your thyroid isn't broken — it's simply starving for the minerals it needs to function? That's the central question at the heart of this conversation with Morley Robbins, creator of the Root Cause Protocol and author of Cure Your Fatigue. Morley has spent nearly two decades reading thousands of peer-reviewed studies to piece together a puzzle that modern medicine has largely ignored — the complex interplay between minerals, mitochondria, and the thyroid gland. In this episode, Morley and Jennifer explore the published research behind a paradigm-shifting idea: that copper deficiency and iron accumulation — not thyroid dysfunction itself — may be at the root of hypothyroidism, hyperthyroidism, and even thyroid nodule growth. From the role of ceruloplasmin as the body's master antioxidant, to the reason your TSH may actually signal copper deficiency, to why zombie cells — iron-toxic cells that lose their ability to die — may be driving nodule formation, this conversation goes …
