Iodine is the one mineral that is often overlooked, yet so critical for much of our bodily functions. Female breast tissue consumes a large portion of the iodine supply in the body, followed by the ovaries & the thyroid gl&. In men, the prostate gland has the highest concentration of iodine. Iodine is critical for neurological development, & indirectly, via the thyroid gland & its hormones, iodine effects the metabolism of every cell in our body.
