I used the ixquick search engine for symptoms of vitamin D deficiency;
found that it is weak bones.
Hm. Never noticed, but...
A university study of schoolchildren during a winter in Edmonton, 
Alberta showed that those who were exposed to the kind of fluorescent 
light that is supposed to duplicate the spectrum of sunlight not only 
got no dental cavities, but the little brown spots on teeth that show 
beginning cavities disappeared.
 From memory years ago, so no url.

I bought a reading lamp that was designed for that kind of light, used 
it for two years, no apparent effect.

The change for the better (stronger, whiter) in my teeth came with raw 
paleofood.

I live at 46°N latitude, and spend an average of a few minutes outside 
in sunlight each day.
