My doctor, a big Vitamin D fan, told me that 40 and up is what he likes for his patients. I've been deficient since he started testing me; I've never been above 20. I take D-3, I eat well, and I spend a little time in the sun, at least when I'm gardening. I don't think there's much else I can do, so I'm choosing not to worry about it at the moment.

It is odd that in all those MS population maps, most of us are far from the equator. It makes you think! I haven't felt any difference since I started the D-3 though. I'd love to get the increased energy my doctor says I'll get.
