Excess Vitamin D disrupt heart rhythm

Scientists have long known that low levels of nutrients that closely associated with heart damage. But a recent research shows, but excess nutrients can lead to atrial fibrillation or heart rhythm disturbances.

The study, presented at the annual meeting of the American Heart Association is melibatkan132.000 patients at the medical center, Utah. Researchers found that the risk of atrial fibrillation when the higher vitamin D levels increased almost three-fold.

each person acquiring daily vitamin D from sunlight. However, for most people living in cold regions where not get enough sunlight - they are taking supplements to improve bone and heart health, says study leader, Dr. Jared Bunch, Director of Electrophysiology Research at Intermountain Medical Center in Murray, Utah.

Bunch suggested, every person who consumed vitamin D is necessary to take blood samples to be examined, whether its use is still within normal limits or not. According to Bunch, many people assume supplements are safe for consumption, so less aware of threats that might have occurred.

"People see this as a way of natural therapies to prevent and treat various diseases. We see many patients who are taking supplements and vitamins in large quantities," said Bunch.

He added that the normal range for vitamin D intake of about 41-80 nanograms per deciliter (ng / dl). While volunteers are involved in this study are known to have an excessive amount of vitamin D (above 100 ng / dl). The recommended daily intake of vitamin D for everyone from 1-70 years of age is 600 IU units.
