funny you say that because Iodine seems to have great effect on iron in the body. much of the taste of blood is the heme.
if i had to guess, magnetism makes the elemental Iodine less reactive, less of an oxidant. cayce called it detoxified. whatever it is, it makes a huge difference. it is particularly evident in the nascent tinctures like magnascent. i love that stuff. its better than a nicotine vap, quad mocha and a gulp or two of O2 all at once.
