Is there any evidence of inability to absorb iodine properly?
I have never heard of such a thing; it makes no sense at all as iodine is used to stain slides, can be absorbed easily through the skin. I would imagine, correct me if I'm wrong, but that it would be absorbed by people who are even missing stomachs.
Are you making things up as you go along.
I see your point about hcl acid with other minerals like iron, but iodine?
