I don’t know much about *all* vitamins being depleted, but I was
diagnosed as anemic shortly after I learned I had GD. I never ever
had a problem with that before. Also I’ve read lots about the
depletion of B12 in pernicious anemia, but think it’s connected as
just another autoimmune disorder. I’m not sure if there is a
direct connection to GD.
Well, now that I re-read this post, not much info here for you, but
I hope it helps a little anyway.
