i live in a supersunny place. even in winter.
the doctor checks my vitamin D levels, says to take supplements
BUT THE SUN HERE! i tell him
then he explains:
1) the type of UV rays we get at these latitudes aren't the best for vit. D synthesis
2) the parts that usually get exposed to the sun aren't enough etc
so, no matter where you are, if you're indoors and / or covered from head to toe all the time, you're gonna be lacking
vit D supplements destroyed my formerly horrible winter depressions
hurrah!
