The reason I started taking Vit D is because my sister, who happens to have type I diabetes emailed me and my other sisters to say that the doctor ran a test and saw that she is deficient and that she should "be sure to tell her sisters" about it because it could run in the family.
Like the blog poster, type II diabetes also runs in my family - both my parents, all of my grandparents had it, except for my grandmother, who had type I. I actually grew up thinking it was like having freckles or blonde hair - just something some people have! - it was so prevalent... Diabetes, and other autoimmune issues (e.g. RA, thyroid issues) run in my family as well although I have been tested and all is well apparently - don't have either.
I actually asked Dr. Check about this and he said this area is one of his "past-times" (immunology and fertility), so he know alot about it, and he said he really doesn't think there is a correlation (at least in my case, but he seemed to be making a general statement).
Anyway, thanks for sharing - will be interesting to see if things improve! Although I am not taking 60,000 Vit D, just 4,000 at the moment!
Thanks, again, Sara H, for taking the time to post!
