Summary

Often referred to as a “Goldilocks” mineral, iodine must be kept in balance—too little can lead to fatigue, thyroid dysfunction, and hormonal imbalance, while too much can exacerbate autoimmunity and disrupt delicate nutrient interplay. In this episode, we take a comprehensive look at iodine’s role in thyroid health, fertility, immune function, breast tissue, and detoxification. We unpack symptoms of both deficiency and excess, explore the connection between iodine and environmental exposures like fluoride, chlorine, and brominated flour, and discuss important considerations for those with Hashimoto’s or other autoimmune conditions. You'll also learn how to assess iodine status through testing, the validity of iodine painting, and the risks and benefits of different supplementation approaches. We highlight topical uses—from wound care and nasal rinses to support for fibrocystic breasts—as well as dietary sources like sea vegetables and seafood. The conversation includes a breakdown of iodized salt, the iodine-selenium relationship, and how to use iodine safely and effectively in your wellness routine.
