Am in Canada, my doctor is Nigerian. He mentioned that for most of his patients, esp. the darker skinned ones, if they come in presenting symptoms of things that could be fixed by Vit D he doesn't even bother ordering blood work anymore -- he just sends em to go buy a bottle of Vit D, and call me if that doesn't work or things get worse.
