Scientist Sees Significant Reduction In Global Mortality Rates If Vitamin D Intake Doubled

July 6, 2011: 07:23 AM EST
Global mortality rates could be cost-effectively reduced by as much as 17.3 percent by increasing serum levels of 25-hydroxyvitamin D, a U.S. study has found. Researcher William B. Grant evaluated the possible impact on mortality rates in six regions of the world if vitamin D intake was doubled. He found that life expectancy would increase an average of about two years. The mortality rate for African females would drop by 7.6 percent, and for European females by 17.3 percent. Doubling vitamin D intake would be cost-effective, according to Grant, because vitamin D supplementation is cheap and supplementation and moderate UVB irradiance have few adverse side effects.
