Common supplement could help you live longer, research suggests

Omega-3, a "healthy fat" that can help improve brain and heart health, has been found to also slow down biological aging.

Upon measuring biological aging in the individuals at the end of the trial, researchers found that omega-3 alone slowed biological aging markers.

Study co-author Professor Heike Bischoff-Ferrari of the University of Basel in Switzerland shared the impact of the clinical trial.

The professor noted that the study findings support the supplementation of 1 gram of algae-based omega-3 daily "as safe and effective."

Fox News senior medical analyst Dr. Marc Siegel applauded the findings, noting that the impact over just three years is "significant, with an additive impact of vitamin D."

The doctor said he believes omega-3 fatty acids can impact longevity due to their antioxidant properties.

"[Antioxidants] work as an anti-inflammatory in the body and are good for heart health," he told Fox News Digital.

Fatty types of fish, including salmon, tuna and mackerel, are also rich sources of omega-3 fatty acids.

Those interested in taking omega-3 supplements should see their doctor to discuss potential benefits and risks, experts recommend.
