Iodine is best known for its relationship to the thyroid, but this conversation goes much further. In this episode of The Holistic Growth Podcast, Dr. Tracey welcomes Phil Coles, co-founder and executive vice president of Good Iodine, and Sharon Cusack, an integrative health coach and inflammation specialist.

Together, they discuss iodine’s role in T3 and T4 thyroid hormones, metabolism, human development, and cellular function. Phil explains the thinking behind Good Iodine’s molecular-iodine formulation and contrasts it with potassium iodide, Lugol’s solution, povidone-iodine, and products marketed as nascent iodine. Sharon shares how she incorporates the product into her practice and the observations that shaped her interest in it.

They also discuss practitioner education, product applications, and why supplement form, dose, and biochemical context matter.

In this episode:

Why iodine is essential to the production of T3 and T4 thyroid hormones
Explanation of molecular iodine versus iodide-based products
Iodine’s relationship to metabolism, energy, pregnancy, and early development
How Sharon uses Good Iodine within her integrative-health practice
The product distinctions and research questions practitioners should examine
