FRIDAY, Nov. 13, 2020 (HealthDay Information) — Hundreds of thousands of individuals take a fish oil or vitamin D complement in hopes of avoiding a bunch of ills. However a brand new examine finds the vitamins will not defend towards the frequent and potential coronary heart rhythm dysfunction generally known as atrial fibrillation.

“A-fib” impacts about 2.7 million Individuals and may result in issues similar to blood clots, stroke and even heart failure. The chance of a-fib will increase with age, high blood pressure and heavy drinking, and could also be extra frequent in some households.

The examine outcomes “don’t help utilizing marine omega-3 fatty acids or vitamin D to forestall atrial fibrillation,” mentioned lead creator Dr. Christine Albert. She’s founding chair within the Division of Cardiology at Cedars-Sinai Medical Heart’s Smidt Coronary heart Institute in Los Angeles.

Then again, “the outcomes do present reassurance that these supplements don’t enhance the general danger of atrial fibrillation and look like usually protected for sufferers who’re taking these dietary supplements for different causes,” Albert mentioned in a information launch from the American Coronary heart Affiliation.

Her group introduced the findings immediately at this yr’s digital annual AHA assembly.

In response to the investigators, prior analysis hasn’t offered clear solutions on both the advantages or harms of vitamin D and omega-3 fatty acids when it got here to a-fib.

This five-year examine included greater than 25,000 adults, 50 and older, with no prior historical past of a-fib. It sought to find out whether or not vitamin D3 dietary supplements of 2000 IU/day or 840 mg/day of omega-3 fatty acids lowered the chance of creating the center arrhythmia.

Throughout the examine, 3.6% of members total did go on to develop a-fib. However there was no statistically vital distinction in danger for a-fib between individuals who took the omega-3 fatty acid dietary supplements and/or vitamin D3 dietary supplements versus those that took a placebo.

Dr. Mitchell Weinberg is chair of cardiology at Staten Island College Hospital in New York Metropolis. He wasn’t concerned within the new analysis, however mentioned the findings got here as “little shock.”


Weinberg believes many individuals place an excessive amount of hope within the energy of dietary supplements to enhance their well being.

“The concept taking extra of a given vitamin will prolong your life or confer vital added well being advantages may be very enticing to the health-conscious affected person,” he mentioned.

However, “whereas quite a lot of advantages have been attributed to those two dietary supplements, the scientific proof shouldn’t be sturdy sufficient to help routine high-dose supplementation,” Weinberg added.

“Whereas vitamin D is essential for bone well being, the declare that vitamin D supplementation decreases the chance for heart disease, cancer and diabetes shouldn’t be very convincing,” he mentioned. “Equally, the beliefs that omega-3 fatty acids lower triglycerides, scale back inflammation and reduce mood-related problems, are with out ample proof.”

Weinberg’s recommendation: “For now, sufferers ought to concentrate on maintaining a healthy diet, exercising usually and persistently following up with a well being care skilled.”

As a result of the brand new findings had been introduced at a medical assembly, they need to be thought-about preliminary till printed in a peer-reviewed journal.
