Prospective Study of Serum 25‐Hydroxyvitamin D Level, Cardiovascular Disease Mortality, and All‐Cause Mortality in Older U.S. Adults

In noninstitutionalized older adults, a group at high risk for all-cause mortality, serum 25(OH)D levels had an independent, inverse association with CVD and all-cause mortality. Randomized controlled trials of vitamin D supplementation in older adults are warranted to determine whether this association is causal and reversible.
