For years, people have known that Vitamin D was good for our bones, but it may also be very important for our hearts, as well. While there is no proof that Vitamin D leads to heart health, new studies have proven there may be a link between the two.

Got vitamin D? It may protect you from heart disease.

Vitamin D, of milk fame, is known for helping with calcium absorption and for building strong bones, which is why it’s routinely added to milk. But there is more and more evidence that vitamin D is a critical player in numerous other aspects of metabolism. A new study suggests many Americans aren’t getting anywhere nearly enough of the vitamin, and it may be affecting their heart health.

In the study, researchers looked at tens of thousands of healthy adults 50 and older whose vitamin D levels had been measured during routine checkups. A majority, they found, were deficient in the vitamin. About two-thirds had less vitamin D in their bloodstreams than the authors considered healthy, and many were extremely deficient.

Less than two years later, the researchers found, those who had extremely low levels of the vitamin were almost twice as likely to have died or suffered a stroke than those with adequate amounts. They also had more coronary artery disease and were twice as likely to have developed heart failure.

The findings, which are being presented today at an American Heart Association conference in Orlando, don’t prove that lack of vitamin D causes heart disease; they only suggest a link between the two. But cardiologists are starting to pay increasing attention because of what they’re learning about vitamin D’s roles in regulating blood pressure, inflammation and glucose control — all critical body processes in cardiovascular health.
