The Midwest is known as the “goiter belt” because of the number of people with enlarged thyroid glands (goiters). This occurs because Midwest diets are lacking in seafood and therefore iodine. We landlocked people, even with modern food systems, are lucky if we get 100 micrograms a day from our salt. The Japanese eat seaweed and get about 12.5 mg/ day from this diet. Iodine not only improves your thyroid, it is an anti-cancer supplement.. The Japanese have the lowest rate of breast cancer in the world. Iodine has been shown to decrease cancer rates in rats, and to kill cancer cells in laboratory tests. A large study was done by a group of physicians known as the “Iodine Project” which details the many benefits of this wonderful and critically important mineral. Our supplement is the Japanese dose of 12.5 mg.
