Due to this, I think it does not matter where you get iodine. You may chose to get it from seaweed or ancient bird droppings from some cave in Chile; but it is still iodine.
Of course, there are ways to get it to assimilate better within the body.
I understand what you mean about its importance and complexity. I'm very well versed on iodine.
And I reiterate what I said in a previous message. Iodine is an oxidant. It has been observed to be a antioxidant, so far, only in a breast disease study. I repeat my assertion that vitamin C and Iodine do not go together any more that does Miracle-Mineral-Supplement with vitamin C.
