The body can have all kinds of symptoms such as those you mention when the balance of essential minerals is off. From my experience (3 years of Nutritional Balancing) Iodine can help the Ca/K ratio but not others. If you eliminate metals and take individually targeted supplements, your nutrient levels will balance and symptoms will go away. The place to start with Nutritional Balancing is to read about it on http://www.drlwilson.com,http://www.traceelements.com, and http://www.nutritionalbalancing.org. If you want to do the program, the next step is to find a practitioner and do a hair mineral analysis test, which will reveal what is going on in your body, and it'll tell you what supplements to take. Blood tests don't reveal what is stored in our tissues, the blood is for circulation and the body takes metals out of circulation, so that method is not accurate. Hair tests with the right labs will give you all the information you need to get better.
