Taking vitamin D supplements in order to overcome a deficiency in the vitamin could cut your risk of dying by more than half. An analysis of more than 10,000 patients found that 70 percent were deficient in vitamin D -- and those who were, were three times more likely to die from any cause.
However, once the deficiencies were corrected by supplements, the risk of death dropped by more than half. In addition, the researchers found that patients with low levels of vitamin D were more likely to have diabetes, high blood pressure, and diseased heart muscle.
According to the study:
“In conclusion, vitamin D deficiency was associated with a significant risk of cardiovascular disease and reduced survival. Vitamin D supplementation was significantly associated with better survival, specifically in patients with documented deficiency.”
