Re: Hveragerthi..Orthoiodosupplementation

 This is true to some extent, fluoride though tends to be residual in bones and teeth, and other tissues, iodine tends to be easily displaced, and once tissue has iodine saturation, the excess is excreted, predominantly in the urine, so it is very unlikely that a person could build up a compounding excess.

I would think that if the body was in great need for the iodine that it would work to hold on to it somewhat. Just like sodium that is either retained or secreted depending on the body's need. And as you pointed out most iodine is excreted through the urine. Thus if iodine is coming out of the skin then it would likely be from excess iodine and the body is using the skin as an additional route of elimination to get levels down to normal as soon as possible. A similar principle is used by the body to maintain glucose. Normally the body will burn most of its glucose being ingested or it will convert to things such as glycoaminoglycans for tissue production. If there is a surplus though the surplus will be converted in to and stored as glycogen. When this system is used up the excess will be stored as fat. If this system is also overburdened then the excess glucose will be dumped out through the urine.
