Utah - When linked to heart disease, vitamin D can be a double-edged sword. Lack of vitamin D can cause heart problems. But new research suggests that vitamin D levels are higher than normal can cause the heart to beat very fast and out of rhythm.
That condition is a condition known as atrial fibrillation. The results of these studies were presented at the annual meeting of the American Heart Association (AHA).
The study has involved 132,000 patients in the Utah-based medical center. Based on the results of these studies found that the risk of atrial fibrillation increased almost 3-fold when vitamin D levels are too high.
"Most people get vitamin D needs daily them from the sun. But the people who live in areas that do not always get enough sunlight, is often recommended to take vitamin D supplements to protect your bones and heart," said Dr. Jared Bunch, director of electrophysiology research at the Intermountain Medical Center in Murray, Utah as reported from MSNHealth.
However, because everyone absorbs these supplements at different levels. The levels of vitamin D in the blood needs to be tested to ensure they are in a safe range. High levels of vitamin D only occurs when people take supplements.
"Because consumers consider counter supplement was safe. Consumers may not be aware of the dangers of eating too much vitamin D. People looked at vitamin D supplementation as a natural therapy for treating various diseases and as a means of disease prevention," said Dr. Bunch.
The normal range for vitamin D consumption is 41-80 nanograms per deciliter (ng / dl). Patients in the study were at risk of heart problems has shown to have excessive levels of vitamin D, which is above 100 ng / dl.
According to the National Institutes of Health, the daily intake of vitamin D is recommended for those with 1-70 years of age is 600 IU units. The recommendations made by an amount sufficient for bone health.
There are few natural food sources of vitamin D, among others:
1. Tuna
2. Fish salmon
3. Cheese
4. Yellow egg
For example, 3 ounces of cooked salmon contains 447 IU of vitamin D per serving. The complete list of foods that contain vitamin D has also been widely available.
"The advice for people newly diagnosed with atrial fibrillation and taking supplements of vitamin D is to make sure the doctor has examined vitamin D levels in their blood. Levels of vitamin D in the blood is too high, thought to have an effect on heart rhythm reversible," said Dr. Bunch.
