Understanding Iodine — The Thyroid, Deficiency, and Why Balance Matters
Iodine is a trace mineral your thyroid can't work without — and one of the few nutrients where both too little and too much cause problems. That balance is the whole story.
This guide explains what iodine does, why deficiency quietly returned in some modern diets, why "more" is not better, and where it shows up in everyday food. It's built to give you the context you need before reaching for a high-dose supplement.
