why don't y'all simply google wh y and how and what instead of ignorantly slamming people . ihave been studying for weeks and the info is out there.For instance iodine deficiency the #1 cause of thyroid problems is due to bromine chlorine and fluoride.
also you might pull up the drug fact sheet for ANY thyroid medication and see that it says to take care of the adrenals FIRST. it is simply not safe to begin any thyroid treatment without testing the adrenal glands first. everything works together in the body.

unlike y'all.
