I have a Vit D thread here with two new medical videos:
http://neurotalk.psychcentral.com/thread92116.html
One cannot get Vit D synthesis from sitting behind glass. The UV is filtered out by the glass.
One cannot get appreciable D from food either. 8oz of fortified milk have 100 IU .
The only main way is to expose yourself to the sun. Or take supplements. D2 from doctors (the 50,000 IU RX form), has been shown over time to NOT WORK. So you will want to use a quality D3 supplement, in a oil/gelcap form, not powder. They are over the counter, and not expensive.
That link has links to medical information on the net. One good source is The VitaminD council. The other is Grassrootshealth.net
