Iodine is an essential nutrient for the thyroid. It is a precursor to our thyroid hormones and helps with our metabolism. Having a low body temperature, cold hands and feet, sluggish metabolism, depression, crying for no reason, elevated blood fats, and hair loss are all indications of a need for iodine. Iodine is needed for other organs also. The second-highest concentration of iodine in the body is in the ovaries. Extra iodine is needed during the change of the seasons and during the dead of winter. Iodine is also needed for infections, especially recurrent sinus infections. David Brownstein, MD, states in his book (Iodine: Why You Need It, Why You Can’t Live Without It) that iodine deficiency plays a large role in the production of breast and other cancers.
