Perhaps you have read about the dangers of various mineral deficiencies. Copper is important for strong blood vessels. Calcium is important for many body functions, not the least of which is to help prevent muscle cramps. Entering the radar recently is an understanding of the role of Iodine and Iodide in the body. I will have more to write about Iodine and Iodide later, but wanted to give you a source at Amazon to consider. Apparently Iodoral has gained mindshare. People are seeing benefits in correcting weight gain, hair loss, hypothroidism, and other conditions some of which are related to high levels of bromides in the food stream.
