i dont live in greece lol... neither am i greek... but i live at the north-sea in germany. i doubt its possible to get Iodine (or enough iodine) by inhaling it or swimming in the sea.
Well maybe if u swim 12 hours per day ... i dunno. (studies???)
I like blood-tests coz they showed me that i messed up my thyroid. Otherwise i would have probably taken much longer to find it out. NOt that blood-tests are always accurate or good to make a diagnose but in my case they were the key and one of the reasons why i m finally here and supplementing with iodoral.
