Description
Iodine is a trace element and its primary function is to support normal thyroid function. Iodine is needed in order to make thyroid hormones T4 (thyroxine) and T3 (triiodothyronine). Thyroid hormones (T4 and T3) are essential throughout life for normal growth, metabolism and the development of the brain and nervous system. Iodine is also trapped by the thyroid gland in order to make a protein called thyroglobulin.
Because of decreased iodine status, due to the Standard American Diet, sufficient T4 (thyroxine) cannot be produced, which negatively affects thyroid function. The use of oral iodine/iodide can assist in getting around this issue. Roughly 80% of the dietary intake of iodine is sequestered by the thyroid gland, but other tissues concentrate iodine as well. These tissues include the gastric mucosa, salivary glands, the gastric mucosa, mammary glands, choroid plexus and the ovaries. Studies also suggest that iodine/iodide helps to maintain healthy hydroxyl estrogen ratios as well.
