Low Vitamin D levels kill?

One study says yes:

Low vitamin D tied to premature death, Study
People with lower levels of vitamin D are twice as likely to die prematurely than those who have higher levels in their blood, said Univ. of Calif.-San Diego researchers.

Lead study author Cedric Garland said 30 nanograms per milliliter of vitamin D was associated with the lower death rate, and that two-thirds of the U.S. have estimated blood levels below 30 ng/ml. Humans can increase their natural production of vitamin D through exposure to sunlight.

“Three years ago, the Institute of Medicine (IOM) concluded that having a too-low blood level of vitamin D was hazardous,” said Cedric Garland, professor in the Department of Family and Preventive Medicine at University of California – San Diego and lead author of the study.

“This study supports that conclusion, but goes one step further. The 20 nanograms per millilitre (ng/ml) blood level cutoff assumed from the IOM report was based solely on the association of low vitamin D with risk of bone disease.

“This new finding is based on the association of low vitamin D with risk of premature death from all causes, not just bone diseases,” Garland said. [...]
