<<Disclaimer: Verify this information before applying it to your situation.>> Hi all- I received several responses directly from people who explained that Celiac is, indeed, an auto-immune disease. I'm posting this publically, since another group of people emailed me directly about this and I'm sure they will want to see the answer. I guess it's back to my health professionals to ask me why they told me melatonin was fine for me even though they were the ones who diagnosed me with celiac in the first place? If anyone has heard from their health professional that melatonin is okay for them to take if their celiac is under control through dietary maintenance, I would appreciated a private email. Thanks very much. Judy Hettena Wright Vermont
