Ingredient overview
What it is
Iodine is incorporated into the thyroid hormones T3 and T4. These hormones help regulate the body's metabolic activity, growth and energy use.
- Scientific identity: Iodine; uptake mechanism: Sodium-iodide symporter (NIS).
- How it works: Absorbed as iodide: Dietary iodine is taken up almost completely from the small intestine and enters circulation as iodide. Concentrated by the thyroid: A dedicated transporter pulls iodide into the gland, which holds most of the body's fifteen to twenty milligrams.
- Primary function: It contributes to normal thyroid function, energy metabolism and nervous-system development.
- What it supports: Iodine supplies an essential building block for thyroid hormones, helping support normal metabolism and daily energy regulation.
- Important consideration: The elemental mineral amount is more meaningful than the weight of its source compound.
