Nutritional balancing, the program by these labs, includes kelp as one of the supplements, a good source of Iodine and micronutrients. Here's a link to an article on Iodine by Dr. Wilson. http://drlwilson.com/Articles/IODINE.htm I used to take LugolsIodine and it didn't seem to make a big difference, but when I started taking kelp it was like someone turned on the lights, I felt much more awake! I still take kelp.
