Guest guest Posted January 1, 2008 Report Share Posted January 1, 2008 hi you can overdose on just about any vitamin or mineral if you take enough of it, iodine is no different. one thing the Iodine folks love to say is that those of us who are hypot due to Hashis (or graves) MUST be iodine deficient. however they never give a reasonable explanation of why this Autoimmune disease (which is named after the Japanese Dr who discovered it in early 1900s) is found in large numbers in Japan - where they get HUGE amounts of iodine in their " conventional " Japanese diet. the fact is that AUtoimmune Thyroid patients have a problem " " processing " iodine in the correct way. -and that's why so many folks -all over the world-- get active autoimmune disease when their iodine intake is changed --in any direction. i hope someone is working on a saliva vs serum test for this right now -Carol > > > > Google this test.

Guest guest Posted January 1, 2008 Report Share Posted January 1, 2008 It certainly can't get much more clear than that. Why is it, though, that some people become so brainwashed on this sbjct, when all this info out here on this, is so darn clear on what will happen to us when we ingest this much iodine? Let alone that it is pretty clear what happens to Hashi's people, in a whole different light? Why is that they are so convinced that they need this ton of iodine, it doesn't make sense to me! Some things are a matter of opinion or clear as mud, in some cases, but this is absolutely straight forward. Re: Iodine Info... > Amelia wrote: >> HI everyone, >> Ok can you overdose on iodine?

Guest guest Posted January 1, 2008 Report Share Posted January 1, 2008 one of the groups along with saying you can take as much t3 as you want is also saying if you have a reaction to iodine, it means just take more. I can't figure oyut why people keep listening. Re: Iodine Info...> Amelia wrote:>> HI everyone,>> Ok can you overdose on iodine?
