Boston (SmartAboutHealth) - Researchers have found that vitamin D may be the key to preventing heart disease.

Researchers were led by Dr. James H. O’Keefe from the Mid America Heart Institute in Kansas City and found that vitamin D plays a major role in heart health.

They looked at adults and compared their vitamin D intake to their risk of heart disease.

What they found was that those who lacked vitamin D saw their risk of heart attack, stroke, and other cardiac events double.

The biggest issue though is that researchers believe the majority of adults do not get enough vitamin D on a daily basis.

What this means is that by increasing vitamin D intake across the board, it could do wonders to prevent heart disease.

The study is featured in the Journal of the American College of Cardiology.
