If you have been trying to run away from the sun in vain, embrace in its rays because the sun is chasing you for your own good. Researchers have discovered that lower level of vitamin D in the blood increases one’s chances of premature death. The findings were revealed based on a systematic review of 32 previously done studies that included the analyses of vitamin D, human mortality rates and blood diseases.
The specific variant of vitamin D that the researchers assessed was 25-hydroxyvitamin D, which is the primary form found in the blood. Cedric Garland, Professor in the Department of Family and Preventive Medicine at University of California, San Diego, and the lead author of the study said that three years ago, the Institute of Medicine concluded that having a really low level of vitamin D in blood is hazardous.
The current study supports this conclusion, but goes a little further. The 20 nanograms per millilitre blood level cutoff assumed from the IOM report was based primarily on the link between low vitamin D with higher risk of bone disease.
Garland said, “This new finding is based on the association of low vitamin D with risk of premature death from all causes, not just bone diseases”. He also said that the amount of vitamin D in the blood that was linked with half of the death rate was 30 ng/ml. It was noted that at least two-thirds of the population in the US had an estimated blood vitamin D level below 30 ng/ml.
Heather Hofflich, professor in the UC San Diego School of Medicine’s Department of Medicine, said, “This study should give the medical community and public substantial reassurance that vitamin D is safe when used in appropriate doses up to 4,000 International Units (IU) per day”.
The study was published in the American Journal of Public Health.
