There's a very simple solution to this debate. Run clinical trials using the same protocol as used for ortho-iodine supplementation... 5 groups... and only change the iodine. One on the standard ortho-iodine supplementation protocol, one using low dose Iodine such as J. Crow has suggested, one using a natural source, one just using the companion nutrients of the protocol and one using a placebo.
If anybody's going to talk Science where Iodine is concerned then they need to back it up with REAL science! This ain't rocket science!
