In the NHANES analysis, fewer than 40 percent of people had D blood concentrations of at least 75 nmol/l. http://www.sciencenews.org/view/generic/id/6916/title/Food_for_Thought__Breathing_Easier_with_Vitamin_D Because humans evolved at equatorial latitudes, without modern clothing and shelter, their vitamin D supply would have been equivalent to at least 100 μg day-1 (4000 units day-1). Thus, the human genome was selected for under conditions where the circulating 25-hydroxyvitamin D (25(OH)D) concentration was greater than 100 nmol l-1. This contrasts with modern humans in whom serum 25(OH)D is typically half that. http://www.ingentaconnect.com/content/routledg/cjne/2001/00000011/00000004/art00006?crawler=true Recent studies have suggested that the optimal vitamin D blood concentration for most adults is at least 75 nmol/l and that elderly people might need at least 100 nmol/l (see Vitamin D: What’s Enough?).
