Here's what a vitamin D has.

Using high - tech nanosensors, researchers from Ohio University have discovered new benefits from vitamin D.

Nanosensors are 1,000 times smaller in diameter than human hair. They were used by researchers to measure the ways in which vitamin D3 affects individual endothelial cells, which have a crucial regulatory role in cardiovascular health.

Malinski's team found that vitamin D3 has a renewable effect on the cardiovascular system, reducing the risk of heart attack and repairing damage done by hypertension, atherosclerosis and diabetes.
