Higher vitamin D concentrations are associated with longer leukocyte telomere length. The difference in leukocyte telomere length between the highest and lowest tertiles of vitamin D concentrations was 107 base pairs, which is equivalent to 5 years of telomeric aging. In addition to being older biologically, the difference was further accentuated by increased concentrations of C-reactive protein, which is a measure of systemic inflammation.
