Beyond the Thyroid – Episode 47: The Ferritin Problem in Thyroid Disease

In this episode of Beyond the Thyroid, Dr. Dana Gibbs explores one of the most overlooked drivers of persistent symptoms in thyroid disease: low ferritin and iron metabolism problems.

Many patients with Hashimoto’s or hypothyroidism continue to experience fatigue, brain fog, dizziness, hair loss, and air hunger—even when their thyroid labs appear “normal.” Dr. Gibbs explains why these symptoms may actually be driven by iron depletion long before anemia appears, and why ferritin levels can quietly sabotage thyroid hormone function.

Through a compelling patient story, Dr. Gibbs walks listeners through the clues that led to the discovery of ferritin levels of 12—and how correcting iron deficiency dramatically improved symptoms.

In this episode, you’ll learn about the bidirectional relationship between iron and thyroid physiology, including how iron affects thyroid peroxidase, T4-to-T3 conversion, and receptor activity.

Dr. Gibbs also discusses common causes of iron deficiency in thyroid patients, including malabsorption, autoimmune gastritis, and celiac disease, and explains how to properly test, treat, and monitor iron safely.

Beyond the Thyroid – Episode 46: When T3 Doesn’t Work — How to Dose Thyroid Medication Correctly (Part 2)

In Part 2 of this T3 deep-dive, Dr. Dana Gibbs explains why T3 thyroid medication often fails because of dosing strategy—not because T3 is the wrong medication.

Building on Episode 45, Dr. Gibbs walks through the most common mistakes clinicians and patients make when starting or adjusting T3-containing medications. She explains why how you dose matters just as much as what you prescribe, and why mismatched T4:T3 ratios, cortisol dysregulation, and insulin resistance can derail even the best treatment plans.

You’ll learn how proper dosing, timing, and lab interpretation can transform T3 from a medication patients fear into one that works reliably and safely. Dr. Gibbs also revisits the case of a patient named Barbara, showing how correcting dosing strategy led to real, sustained improvement.

This episode is essential listening for anyone who has tried T3 and felt worse—or wants to get it right the first time.

Beyond the Thyroid – Episode 45: When T3 Doesn’t Work — Why Thyroid Medication Can Make You Feel Worse (Part 1)

In this episode of Beyond the Thyroid, Dr. Dana Gibbs tackles a frustrating and surprisingly common problem: why T3-containing thyroid medications don’t always help—and can sometimes make patients feel worse.

Drawing from years of clinical experience and personal insight, Dr. Gibbs explains that when T3 “fails,” the problem is often not the medication itself, but the physiology surrounding it. She walks through the most common reasons T3 is poorly tolerated, including stimulant sensitivity, blood sugar instability, cortisol dysregulation, circadian rhythm disruption, and nutrient deficiencies.

Dr. Gibbs shares the real-life case of a patient named Barbara, illustrating how strategic changes to medication timing, lifestyle factors, and metabolic support led to dramatic improvement after years of struggle. She also provides practical guidance for patients and clinicians on how to safely optimize T3 therapy.

This is Part 1 of a deeper series on T3 therapy and thyroid optimization.

Tune in to understand why T3 doesn’t always work—and what to fix before giving up on it.
