Vitamin D has a good reputation even in the worthy company of other vitamins, having been associated variously with cardiovascular health, strong bones, cognitive health, cancer protection and immune health.
Scientists from the Heart Institute at Intermountain Medical Center in Salt Lake City now claim to have dug up stronger evidence supporting the cardiovascular benefits of vitamin D. They also claim to have more firmly established the link between a lack of the vitamin in the diet and heart disease.

The nice thing about vitamins or nutrients in general is that the more research is done about them, the more benefits come to light! Whereas with pharmaceutical drugs, it seems the more they are researched, the more side effects come to light.
