Well, I wouldn't use it. 20 mg in a 16 oz bottle? And I don't think we need Iodine that can "pass into the cell without being digested", especially since Iodine is needed by the gastric mucosa, cet.
I'd heard of angstrom minerals before, just not angstrom iodine. I have no opinion as to the efficacy of angstrom minerals. Iodine is not a mineral anyway, I don't see the point of angstromizizing it. (pretty sure that that's not a word, angstromizizing:) hehehe...
I've seen a lot of iodine supplements created in the last three years. Just sayin'...:)
