Vitamin D may reduce elderly heart disease and diabetes risk

High blood levels of vitamin D may be at a 33 percent lower risk of developing heart disease, says a new review.

According to the systematic review and meta-analysis of 28 observational studies, the highest blood levels of vitamin D in middle aged and elderly people were associated with a 33 percent reduced risk of cardiovascular disease (CVD), a 55 percent reduction in the risk of type 2 diabetes, and a 51 percent reduction in the risk of metabolic syndrome, compared with the lowest blood levels of vitamin D (1).

The study adds to a rapidly expanding body of evidence supporting the benefits of adequate vitamin D levels, which have seen leading scientists around the world call for increases in the daily intakes of the vitamin.

The underlying mechanism is not fully understood. Before recommendations can be made, however, the researchers noted that additional controlled trials are needed to investigate the association, as well as to test if vitamin D supplementation may reduce the risk of cardio-metabolic disease.
