I found this link
http://www.vitamindcouncil.org/healt...y-autism.shtml
in my online travels. My daughter is pregnant and her twin brother is autistic so we were very interested in that connection. It needs to be researched further for sure. In the meantime, they are conducting a study through the Autism Research counsel...5000 units a day for pregnant women. The women in the study already have one autistic child.
I know of several women my age (46) and younger with tested low vitamin D and osteopenia. Including myself. It seems as though the d3 is safer for supplementation than d2.
I also researched the connection on low D and celiac disease and at least one doctor has posited that theory, and vitamin D supplementation as a "cure" for celiac.
