Too much vitamin D could be harmful to heart ..

Studies have shown that vitamin D is critical for bone health and could have a protective benefit for the heart, but new research suggests that too much of it could actually be harmful.
n conducting the study, published issue of the American Journal of Cardiology, researchers examined five years of data from a national survey of more than 15,000 adults. They found that people with a normal levels of vitamin D had lower levels of a c-reactive protein (CRP), a marker for inflammation of the heart and blood vessels.
On the other hand, when vitamin D levels rose beyond the low end of normal, CRP also increased, resulting in a greater risk for heart problems.
