A clinical study conducted at the University of Kansas investigated the associations between vitamin D blood levels, vitamin D supplementation and the incidence of cardiovascular disease. Of 10,899 patients observed over a period of 5 years and 8 months, low vitamin D levels were associated with a significantly increased risk of cardiovascular disease and a shortened lifespan. In contrast, vitamin D supplementation was associated with a significantly increased life expectancy. Further details can be found in the study.
