Recent Advances in Iodine Nutrition

Iodine supports the health of many organs in the body. It is taken up by most every gland and, when taken in milligram quantities, is found in nearly every tissue of the body. The thyroid cannot function properly without an adequate supply of iodine, and much of the subclinical hypothyroidism in the USA is likely just a shortage of iodine. The immune system uses iodine to fight infections, so many chronic illnesses tax the body’s iodine supply. The reproductive glands and tissues have high levels of iodine in them, if iodine is provided. This iodine is necessary for optimal function of the breasts, ovaries, endometrium, and prostate. Research has shown that milligram amounts of iodine can reverse fibrocystic breast disease. Iodine suppresses chemically-induced breast cancer in rats. Iodine balances estrogen levels, thus supporting ovary health. Sufficient iodine is needed for a stable rhythmic heart beat. Iodine, directly or indirectly, can normalize serum cholesterol levels and normalize blood pressure. Iodine attaches to insulin receptors and improves glucose metabolism, which is good news for people with diabetes. Iodine is essential for the development of the central nervous system; women need a good supply before becoming pregnant. Iodine may also play a role in bone health and lung function. Even the skin needs iodine. Iodine has been shown to help remove heavy metals from the body along with bromide.
