Vitamin D: Sun exposure no guarantee

NEW YORK: In many people, vitamin D levels can remain low despite abundant exposure to sunlight, research shows.

Inadequate Sun exposure is often blamed for the high prevalence of low vitamin D status, the authors explain, but the truth of this has been unclear.

Dr Neil Binkley with the University of Wisconsin Osteoporosis Clinical Research Program, Madison, and colleagues investigated the vitamin D status of people living in Sun-drenched Hawaii.

Despite this abundant Sun exposure, 51% of these individuals were found to have low vitamin D levels, the researchers found. “This implies that the common recommendation to allow Sun exposure for 15 minutes may not ensure vitamin D sufficiency,” Binkley said.
