Except that it is more probable that most people always make enough vitamin D. It requires only 45 minutes a week sun exposure with otherwise proper nutrition. Those few who live in polar climes in winter and those unfortunates that don't get out enough may need supplementing. It seems it is added to milk at least partly because vitamin D's job is promoting calcium adsorbtion in the intestines. I beleive vitamin D is the only vitamin naturally produced in the body.? --rmhermen |
