Vitamin D: a clinical perspective


CORRESPONDENCE Allan C. Halpern, e-mail:

This ‘Perspective’ presents data supporting the viewpoint that physicians should not routinely test vitamin D levels in the general population but should routinely endorse vitamin D supplementation at levels recommended by the Institute of Medicine. It further reasons that it is unadvisable to recommend intentional limited sun exposure as a source of vitamin D.
