I am an avid follower of Dr. Jonathan Wright, and Dr. Mercola. The information on Dr. Wrights site is excellent regarding hypothyroid and Iodine. Two Dr's said in all their yrs of practice, I have the worst case they have ever seen, and described it as "off the charts" I have went from an energetic thin person to overweight, exhausted, depressed and anxiety ridden person overnight. I feel so ill sometimes, I even thought maybe I had cancer. After reading Dr. Wrights site last week, I purchased iodine (colored) to test my iodine, [put the orange color on my inside arm, and it completely disappeared within an hour. I then ran to a health food store, and purchased Iodine, and literally overnight, I felt better than I have in years. In 2 days, the huge lump I had on the right side of my neck, is completely gone. Nothing short of amazing for me. I plan on adding _____s apple cider vinegar next, and a few supplements that are purported to assist.
