Yes, but very marginally, and Gracia was not taking a radioactive form of iodine, just the stable stuff. The amount of radioactive iodine you could tolerate in your body is much less than what Gracia (or any of us) is taking. > ...

No enzyme, just a simple displacement. But, it is not the similarity in size that matters, its the chemical similarity. They are both halogens with -1 valence. > > Also, am I correct in thinking iodine is water soluble, rather than > fat soluble, as someone compared it to vitamin A in another post > somewhere (I couldn't find it earlier today)...which would mean excess > would leave the body more quickly than excess of something that > attaches to fat molecules, right? All correct. Elemental iodine in the body is almost instantly reduced to the anion (iodide), which is very soluble. When it gets attached to thyronine, it stays in the body a little longer.
