Newport, when you say "As it turns out the thyroid wants elemental Selenium...", do you mean your thyroid or all thyroids in general?
Then, isn't SeMC also an anti-oxidant? Wouldn't it be beneficial during Iodine therapy as well as elemental? In other words, maybe both. Since most supplements contain the selenium from yeast, I wonder how to get the selenite and selenate; or the inorganic selenium salts.
