No..... glass filters out UV.... which is required for skin manufacture of D3. Also people using statins, will probably not convert in the skin, well or at all. There is some talk about elderly people losing the ability to make D3 in the skin due to age.
For all those on this thread who are new.... there is a D3 thread on our Vitamin forum here. I've been collecting all the newest news about it and treatment options...
http://neurotalk.psychcentral.com/thread92116.html
This D thread was made for the neuropathy/chronic pain aspect, but there is much more at the Vitamin forum.
Also there are several D3 threads mixed into the regular index of threads.
