Iodine is a vital essential trace element and indispensable for our health. Our bodies need iodine for the production of hormones in the thyroid gland. These thyroid hormones are indispensable for numerous metabolic processes in our body, such as energy metabolism, cognitive function and nervous system function. About 70 to 80 percent of the iodine ingested is consumed in the thyroid gland. If there is not enough iodine available, the thyroid gland produces too few hormones. If the hormonal balance is disrupted due to iodine deficiency, numerous metabolic processes are impaired. The entire organism can get out of balance.
