You can’t make thyroid hormone without iodine, and some “hypothyroid” pictures are really deficiency. Test first, start with selenium, begin iodine low, and monitor labs every 6–8 weeks. Anyone on thyroid medication should only adjust it with their prescriber, since needs can change as status improves.
This is the controversial one. Conventional guidance often avoids iodine in Hashimoto’s; some practitioners use it cautiously with adequate selenium, starting very low and watching antibodies closely. Individual response varies — and rising antibodies are a signal to stop.
Breast tissue concentrates iodine, and fibrocystic tissue tends to be iodine-depleted. Clinical work (notably Dr. William Ghent’s 1993 studies) reported meaningful improvement in breast pain and nodularity with iodine over 3–6 months, using dual-form iodine plus companion nutrients.
The ovaries hold the second-highest iodine concentration in the body, and cysts are associated with deficiency; many practitioners report resolution over 3–6 months. The prostate likewise concentrates iodine, with zinc as an especially important companion nutrient.
In a nuclear release, radioactive iodine (I-131) concentrates in the thyroid. Saturating the thyroid with stable iodine (potassium iodide) blocks that uptake — most protective when taken before or within a few hours of exposure. This is an emergency use with established pediatric and adult dosing, separate from general supplementation.
