Cool! I'll have a look, thank you! I wonder if they ship to Brazil (edit: just checked, and they don't ). However, I did find this Lugol solution on a Brazilian website. Is that the same as taking iodine tablets?I don’t know if it’s been mentioned but Hakala Labs sell lugol type stuff including pill form in various strengths as well as self-test kits to check your levels. I find them quite good. Pricing seems fair for what they offer. Billy Joe Bob sez, check ‘em out!
