A study carried out by the University of Jerusalem examined the association between vitamin D blood levels and vitamin D supplementation on the mortality rate of patients with heart failure. The study compared 3,009 patients with low vitamin D levels with a control group comprising 46,825 participants . The study showed that vitamin D deficiency was significantly associated with increased mortality in heart failure patients. In addition, vitamin D supplementation was linked to a significant (P < 0.0001) reduction in mortality in heart failure patients. Further details can be found in the study.
