thegeby.blogspot.com - Researchers have found that people with lower blood levels of vitamin D are twice as likely to die prematurely than those with higher blood levels of vitamin D.
The finding was based on a systematic review of 32 previous studies that included analyses of vitamin D, blood levels and human mortality rates.
The specific variant of vitamin D assessed was 25-hydroxyvitamin D, the primary form found in blood.
"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.
Garland said the blood level amount of vitamin D associated with about half of the death rate was 30 ng/ml. He noted that two-thirds of the US population has an estimated blood vitamin D level below 30 ng/ml.
