A Deep Dive on Iodine, Thyroid Nodules, and Goiters with Dr. Angela Mazza

In this episode, Dr. Eric Osansky welcomes back Dr. Angela Mazza, a triple board-certified endocrinologist specializing in thyroid health, metabolic medicine, and integrative endocrine care. The discussion centers around two topics Dr. Mazza has recently published journal articles on: iodine and thyroid nodules. Together, they explore why iodine remains one of the most controversial nutrients in thyroid medicine and why individualized care is critical when determining whether supplementation is appropriate. Dr. Mazza explains the delicate balance of iodine intake, discussing why both deficiency and excess can create thyroid problems. She also shares her approach to iodine testing, addresses common misconceptions about iodine supplementation, and discusses special considerations for Hashimoto’s thyroiditis, Graves’ disease, pregnancy, and breastfeeding. The conversation then shifts into thyroid nodules, where Dr. Mazza explains the most common causes of nodule formation, the role of inflammation, estrogen, insulin resistance, environmental toxins, and genetics, along with how toxic nodules differ from non-functioning nodules. The episode wraps up with an in-depth discussion on goiters, radiofrequency ablation (RFA), thyroid cancer, and modern alternatives to surgery. Dr. Mazza also explains how she evaluates thyroid nodules using ultrasound and shares her perspective on personalized treatment approaches.

In this episode, Dr. Eric Osansky explores a common question he receives from people with hyperthyroidism: Can I incorporate intermittent fasting? While fasting has been praised for benefits such as weight loss, blood sugar regulation, reduced inflammation, and improved metabolic health, Dr. Eric explains why those with hyperthyroidism and Graves’ disease need to approach fasting differently than the general population. Dr. Eric reviews the most common fasting methods, including overnight fasting, 16:8 intermittent fasting, alternate-day fasting, water fasting, and fasting-mimicking diets. He explains how hyperthyroidism creates a catabolic state characterized by increased metabolism, muscle breakdown, and weight loss, making prolonged fasting potentially problematic for some people. He also discusses the important roles of adrenal health, cortisol balance, blood sugar regulation, insulin resistance, and stress when determining whether fasting is appropriate.Throughout the episode, Dr. Eric emphasizes the importance of individualization. While fasting may offer benefits for certain people, especially those with stable thyroid levels and insulin resistance, it may be counterproductive for others who are actively hyperthyroid, losing weight, struggling with adrenal dysfunction, or experiencing significant symptoms.

In this episode, Dr. Eric Osansky takes a deep dive into black seed oil (Nigella sativa) and its potential role in supporting thyroid and autoimmune thyroid conditions such as Hashimoto’s thyroiditis and Graves’ disease. He explains the differences between whole black seed, powdered black seed, black seed oil, and black seed essential oil, highlighting why these distinctions matter when interpreting the research. Dr. Eric reviews the available studies, including a clinical trial involving people with Hashimoto’s thyroiditis that demonstrated improvements in thyroid markers, thyroid antibodies, and metabolic health. He also discusses the antioxidant, anti-inflammatory, and immune-modulating properties of Nigella sativa, exploring how these mechanisms may support immune system balance and potentially benefit those with autoimmune conditions. Along the way, he addresses important considerations such as supplement quality, thymoquinone content, product variability, and potential contraindications.Finally, Dr. Eric offers a balanced perspective on where black seed oil fits into a comprehensive thyroid-healing strategy. While the research is promising, he explains why it isn’t a supplement he routinely recommends to every patient and discusses how it compares to other antioxidant-support supplements. If you want a clearer understanding of black seed oil, the science behind it, and whether it may have a place in your thyroid health journey, you’ll get a lot out of this episode.

In this episode, Dr. Eric Osansky tackles a question that often surprises thyroid patients: Can Hashimoto’s thyroiditis turn into Graves’ disease, and can Graves’ disease eventually become Hashimoto’s? While these conditions are commonly viewed as opposites—one causing hypothyroidism and the other hyperthyroidism—Dr. Eric explains why the relationship between them isn’t always so straightforward. Dr. Eric breaks down the differences between the thyroid antibodies associated with each condition, explains how antibody patterns can overlap, and discusses why some people test positive for both Graves’ and Hashimoto’s antibodies at the same time. He also explores possible reasons these transitions occur, including immune dysregulation, environmental triggers, gut health issues, nutrient deficiencies, chronic stress, infections, mold exposure, and hormonal changes. Along the way, he clarifies common misconceptions about Hashitoxicosis, “thyroid burnout,” and the importance of proper antibody testing.Most importantly, Dr. Eric emphasizes that both Graves’ disease and Hashimoto’s are immune system conditions rather than simply thyroid disorders. By focusing on identifying triggers, restoring immune balance, and supporting gut health, it’s possible to improve symptoms, lower antibodies, and achieve long-term remission. If you want a clearer understanding of how autoimmune thyroid conditions can evolve over time—and what you can do about it—you’ll get a lot out of this episode.

In this episode, Dr. Eric interviews acupuncturist, author, and educator Robin Ray Green about the often-overlooked environmental stressors that can silently interfere with thyroid health, immune function, energy, and healing. Drawing from her own personal journey with mold illness, Robin explains how invisible stressors like mold, poor water quality, EMFs, and air pollution can overwhelm the body—even when someone is following a clean diet and healthy lifestyle.Robin shares how chronic mold exposure dramatically impacted her health, leading to debilitating fatigue, brain fog, and burnout despite doing everything “right.” This experience led her to explore the deeper root causes of chronic illness and uncover how environmental toxins, poor sleep environments, electronic pollution, and hidden emotional stressors can keep the body stuck in a constant state of stress and inflammation.The conversation also explores practical strategies for reducing toxic burden, improving sleep quality, choosing better water filtration systems, minimizing EMF exposure, and supporting the body’s natural healing processes.

In this episode, Dr. Eric Osansky discusses an important reality many people with hyperthyroidism and Graves’ disease eventually face: doing everything “right” with diet and lifestyle, yet still not experiencing complete healing. Dr. Eric explains why foundational practices like following an anti-inflammatory diet, reducing stress, improving sleep, and taking nutritional supplements are essential—but often only part of the solution.He dives into the deeper root causes commonly overlooked in conventional and even natural approaches to thyroid healing. Topics include gut infections such as H. pylori, parasites, SIBO, and candida overgrowth, along with environmental toxins and toxicants like mold, microplastics, glyphosate, and heavy metals. Dr. Eric also explores the importance of vagus nerve support, nervous system regulation, oral health, and reducing toxic burden through cleaner living environments and healthier daily habits.Throughout the episode, Dr. Eric emphasizes the importance of functional medicine testing and individualized care while also discussing common mistakes people make during their healing journey—such as relying solely on diet, avoiding testing altogether, or jumping from protocol to protocol. If you feel stuck despite making major lifestyle changes, this episode will help you better understand what may be missing and what steps to consider next in your healing journey.

In this episode, Dr. Eric Osansky welcomes back Dr. Amie Hornaman to discuss her new book, The Thyroid Fix. Together, they dive into the most common misconceptions surrounding hypothyroidism and Hashimoto’s, including why so many people continue to experience symptoms despite being told their thyroid labs are “normal.” Dr. Amie shares her personal motivation for writing the book and explains how she hopes to empower people to better understand their thyroid health and advocate for themselves.Dr. Amie breaks down what a complete thyroid panel should include, why testing only TSH is often insufficient, and the important roles of free T3 and reverse T3 in thyroid hormone conversion and metabolism. The conversation also explores autoimmune triggers, hormone fluctuations during pregnancy and menopause, the connection between stress and thyroid dysfunction, and why testosterone may play a protective role against autoimmunity. They also discuss T2 supplementation, common nutrient deficiencies, iodine, ashwagandha, and the growing conversation around GLP-1 medications.The episode closes with an encouraging discussion about hope, healing, and the importance of individualized thyroid care. Dr. Amie emphasizes that taking thyroid hormone replacement is not a failure and explains when Hashimoto’s may potentially be reversed or put into remission.

In this episode, Dr. Eric Osansky dives into the often-debated topic of gluten and grains—and their impact on thyroid health, especially in those with Graves’ disease and Hashimoto’s. While many people understand the need to avoid gluten, there’s still a lot of confusion around whether gluten-free grains are truly safe during the healing process.Dr. Eric explains why gluten is a common trigger for autoimmune conditions, touching on mechanisms like increased intestinal permeability (leaky gut), immune activation, and molecular mimicry. He also breaks down the bigger picture of grains as a whole, including how compounds like phytates, lectins, and even mold exposure can interfere with gut healing—even when gluten isn’t present. You’ll also hear his perspective on controversial topics like sourdough bread, eating gluten in other countries, and whether glyphosate is to blame.He wraps up by emphasizing a practical, balanced approach: while some people may tolerate certain grains, removing both gluten and grains—at least temporarily—can significantly improve your chances of restoring gut health and achieving remission.
