Iodized table salt is the most common and effective source, where potassium iodide is added to ensure adequate intake. The Iodide Ion and Its Formation Iodide (I⁻) is the reduced, anionic form of iodine.
Why the Thyroid Gland Selects Iodide Over Iodine
This simple change in electron count transforms its properties dramatically. Iodide ions are colorless in solution, a stark contrast to the vibrant violet of elemental iodine.
The Chemical Nature of Iodine In its purest, elemental state, iodine exists as a diatomic molecule, denoted as I₂. Elemental iodine is relatively rare in nature because it is highly reactive.
