I am convinced that I am probably iodine deficient, so I started taking kelp pills. I bought the Solgar brand. I thought that I could take many of these, however I read about possible high levels of arsenic in kelp and have reduced my intake to just two tablets a day. I guess I should try to find a different source of iodine. I started using more iodized salt, however there is only so much salt one can take in before overdoing it. I guess I should look for a new source. How much iodine should one take? Some say one could take 25-50 mg a day for short periods, while others say not to exceed half a mg(500 mcg) a day.
