Iodine deficiency is responsible for many symptoms of illness including fatigue, aches and pains, weight gain, memory loss, etc. Deficiency can also result in impaired physical and mental development (primarily in children). Not only is iodine vital for the creation of thyroid hormones, it is also required to produce every other hormone in the body. Once the thyroid gland has attained iodine saturation, any excess is utilized by other tissues, such as the nasal cavities, gut, breasts, stomach, bones and connective tissue. The immune system must also have sufficient iodine to function properly. Additionally, iodine is drawn on for its use as an antibacterial, anti-parasitic, and anti-viral agent. Unfortunately, iodine deficiency is a major global concern affecting over one billion people worldwide with the primary issue stemming from the lack of Iodine content found in most foods.
