Personally, I'm expecting the seaweeds along with Lugol's to be the answer. The unknown factor for me is dosage.
There are special things in seaweed which remove pollution from our bodies along with the Iodine, as I understand it.
Best book on the healing effects of seaweed (My house has so many bookcases, it looks like a library.) is Susun S. Weed's book Healing Wise. I think she's offbeat, feminist, whatever, but more/best information I've ever read on the subject.
