Being in the lowest quartile (defined as vitamin D levels less than 17.8 ng/mL) was associated with a 26% increased rate of death from any cause (mortality rate ratio, 1.26; 95% CI, 1.08 1.46). The adjusted models of CVD and cancer mortality revealed a higher risk, but it was not statistically significant.Source: [ Arch Intern Med. 2008 Aug 11;168(15):1629 37.]Vitamin D could add 5 years to your life span.Among many factors that may be responsible for the apparent effect of vitamin Ds on all cause mortality is the effect of this vitamin on telomeres (the terminal end of each gene) and its potential effect on slowing aging. Richards and coworkers examined whether vitamin D concentrations could slow the rate of shortening of telomeres on leukocytes (a marker of aging). Leukocyte telomere length (LTL) is predictive of the development of numerous aging related disease, and length of leukocyte telomeres decreases with each cell division and with increased inflammation (more common in the elderly). Researchers measured the concentrations of vitamin D in the blood of 2160 women aged 18 79 years (the mean age of these women was about 49 years) from a large population based study. This study divided the group into thirds [tertiles] based on vitamin D levels, and found that increased age was significantly associated with shorter LTL (r = 0.40, PSource: [Am J Clin Nutr. 2007 Nov;86(5):1420 5.]This information was originally posted at: Beneficial Effects of Vitamin DDr.
