Same here, as  Hashimoto Thyroid disease patient - I am not allowed to
ingest iodine either. In fact, when I was unwittingly ingesting sea salt -
my doctor figured out what was still triggering my issues --- he asked if I
was eating sea salt with iodine. Sure enough I was.
When I stopped, I felt much better.
I asked a health food store if Evolution sea salt had NO iodine and they
confirmed. Been using that since and I'm fine now.
