That "old medical myth" has studies as recent as 2011/2012 showing that consumption of over 400 micrograms/daily of Iodine can cause subclinical hypothroidism [1]. That study needs to be confirmed, but given current recommended consumption in the 150-300 micrograms/daily range, recommending the consumption of 4x recommended levels or more as "should not do any harm" is strictly bad advice. I'm stoked for you that you seem to have managed to treat your asthma problems with two mineral supplements, but please try to cite your research before trying to give medical advice.
