Heart Harvard researchers have said that a lack of vitamin D could increase one’s risk of heart attacks, strokes and other such cardiovascular problems.

Dr.Thomas Wang of Harvard Medical School said that the risk of problems goes up by 60% only if the personal has a moderate vitamin D deficiency.

And, if you have a very severe deficiency, the risk can go up by nearly 100%.

“A number of laboratory studies suggests that vitamin D has a variety of important effects on the heart and the blood vessels surrounding the heart,” said Dr.Wang.

Sources of vitamin D include milk, fish and of course sunshine. Supplements of vitamin D are also very effective.
