Iodine

Iodine is a crucial element in modulating thyroid function and autoimmune processes. Iodine deficiency attenuates autoimmune thyroiditis in individuals prone to the condition, while iodine excess accelerates it 3. The element plays a significant role in the afferent, central, and efferent stages of thyroid autoimmunity, and its deficiency can lead to a reduction in thyroidal infiltration and decreased production of thyroglobulin antibodies 1.

Iodine has been shown to have antifungal properties, making it an effective treatment for fungal infections such as fungal toes 2. Additionally, iodine can be used as a protective agent against radiation damage, particularly when combined with thyroid and progesterone 4. However, excessive iodine intake can lead to thyroid gland impairment and increased sensitivity to iodine, potentially triggering Hashimoto's thyroiditis 5.

The effects of iodine supplementation can be complex, and high doses can be detrimental to thyroid health over time. Ray Peat notes that large doses of iodine can be safe for short-term therapeutic use but may cause harm when taken in excess for extended periods 8. Furthermore, the incidence of thyroid cancer has doubled in the last 30 to 40 years, and excessive iodine intake may contribute to this trend 8.

In terms of nutritional support, magnesium is essential for repairing radiation damage and should be taken in conjunction with thyroid activation 4. A balanced ionic balance, including magnesium, zinc, manganese, and molybdenum, is also crucial for regulating various aspects of metabolism, including glycolysis, respiration, hormone secretion, and immunity 7.
