Thyroid Health Simplified: Functional Testing, Natural Healing, and Lifestyle Strategies

S3 E27 • Jul 8, 2025 • 39 mins

In this episode, Dr. Alfred Alessi explores thyroid dysfunction, beginning with thyroid function and the HPT axis. He contrasts conventional and functional medicine approaches to testing, emphasizing the importance of recognizing symptoms of thyroid issues and Hashimoto's disease. Dr. Alessi discusses comprehensive testing, essential micronutrients, and environmental factors in a functional medicine context. Natural healing, stress, and gut health's impact on thyroid function are examined. The episode highlights nutrients, adaptogenic herbs, and lifestyle interventions for thyroid support, concluding with free resources and a call for listener engagement.

Key Points

  • Thyroid dysfunction is often misdiagnosed or undiagnosed due to the limited scope of conventional testing, which typically only includes TSH and T4 levels.
  • Functional medicine takes a comprehensive approach to thyroid health by also examining factors like gut health, nutrient deficiencies, and autoimmune markers to identify root causes of dysfunction.
  • Healing the thyroid naturally involves removing dietary and environmental triggers, supporting gut health, and using targeted nutraceuticals and lifestyle changes to restore balance and function.
