Naturally occurring iodine is a rare trace element that was discovered in the 1800’s by a French chemist. It was found to be effective in the treatment of goiter (swelling of the thyroid gland), and in 1924 the United States initiated its use as an additive to common table salt to address the high incidence of iodine deficiency. As a result, the once-common condition of goiter in the U.S. was virtually eliminated.
It is highly accepted that iodized salt is sufficient to meet the body’s requirements. Although this assertion has been taught in medical schools for several decades, many studies counter that claim. Furthermore, researchers have found that the iodine in salt has poor bioavailability, meaning that the body does not fully absorb the dosage.
