Window direction is irrelevant. UV-B (which triggers production of Vitamin D) gets blocked by almost all glass. I guess windows will help if you leave them open, but if you're just sitting next to an open window all day I'd say why not just sit outside?
But, yeah, make sure you get your vitamin D whatever way you can. Supplements, dietary, sun exposure, whatever works for you
