Fish oil, vitamin D will not prevent A-fiber: Analysis

THURSDAY, MARCH 18, 2021 (HealthDay News) – In an effort to prevent heart rhythm disorder known as “a-fib,” new research shows that taking vitamin D or supplemental fish oils will not help.

A-fib, also called atrial fibrillation, affects more than 33 million people worldwide and is the most common form of abnormal heart rhythm. It can cause symptoms that affect a person’s quality of life, can cause blood clots that can cause a stroke, and can also cause heart failure.

For the study, the researchers looked at whether taking vitamin D supplements or omega-3 fatty acids found in fish oil could cause different types of fiber, and some patients could benefit or harm the supplements.

Overall, the results were mostly consistent across different a-fib and patient groups, according to author and colleague Dr. Christine Albert. Albert is the head of the cardiology department at the Smidt Heart Institute in Los Angeles.


The study was published on March 16 Journal of the American Medical Association, After Albert’s presentation at an American Heart Association conference last year.

“Our recommendation remains the same,” he said JAMA Network news. “We do not allow fish oil or vitamin D supplements to be taken to prevent atrial fibrillation.”

However, “Unlike other recent trials that found higher risks of atrial fibrillation with omega-3 fatty acid supplements with higher doses, our research did not find a significantly increased risk of atrial fibrillation with a gram of fish oil per day. That’s good news. for people who take fish oil for other health conditions, ”Albert said.

His team also found that international vitamin D supplements of 2,000 units a day do not increase the risk of fib-fib.
