Major Meta-Analysis: Omega-3 Fish Oil Supplements Linked With Lower Cardiovascular Disease

Individuals who obtained omega-3 fish oil dietary supplements in randomized medical trials had decrease dangers of coronary heart assault and different heart problems (CVD) occasions in contrast with those that got placebo, in accordance with a brand new meta-analysis from Harvard T.H. Chan College of Public Well being and Brigham and Ladies’s Hospital. Researchers discovered an affiliation between each day omega-3 supplementation and decreased threat of most CVD outcomes, together with coronary heart assault, dying from coronary coronary heart illness, and dying from CVD, however didn’t see profit for stroke. As well as, greater doses of omega-3 fish oil dietary supplements appeared to offer even larger threat discount.

The research was published online on September 30, 2019 within the Journal of the American Coronary heart Affiliation.

“This meta-analysis gives probably the most up-to-date proof relating to the results of omega-3 supplementation on threat of a number of CVD outcomes. We discovered important protecting results of each day omega-3 supplementation towards most CVD end result dangers and the associations gave the impression to be in a dose-response method,” stated first writer Yang Hu, a postdoctoral fellow within the Division of Diet at Harvard Chan College.

Whereas observational research have proven an affiliation between fish consumption and decrease coronary heart illness threat, outcomes from randomized managed trials (RCTs) have been inconsistent. Two evaluations revealed final yr didn’t discover clear proof for profit.

On this new evaluation, the researchers did an up to date meta-analysis that included three just lately accomplished large-scale trials, which elevated the pattern measurement by 64%. The overall inhabitants analyzed by Hu and colleagues included greater than 120,000 adults in 13 randomized trials worldwide. The evaluation included the VITAL trial, the most important randomized trial of omega-3s to this point.

The findings confirmed that individuals who took each day omega-3 fish oil dietary supplements, in contrast with those that took a placebo, lowered their threat for many CVD outcomes besides stroke, together with an 8% decreased threat for coronary heart assault and coronary coronary heart illness (CHD) dying. The affiliation was significantly evident at greater doses of omega-3 fish oil supplementation. This discovering might recommend that marine omega-3 supplementation dosage above the 840 mg/day utilized in most randomized medical trials might present larger reductions in CVD threat. Provided that a number of million individuals expertise these CVD occasions worldwide every year, even small reductions in threat can translate into tons of of 1000’s of coronary heart assaults and CVD deaths averted, in accordance with the researchers.

“Though public well being suggestions ought to concentrate on growing fish consumption, having an general heart-healthy weight loss plan, being bodily energetic, and having different wholesome life-style practices, this research means that omega-3 supplementation might have a job in acceptable sufferers,” stated senior writer JoAnn Manson, chief of the Division of Preventive Drugs at Brigham and Ladies’s Hospital and professor within the Division of Epidemiology at Harvard Chan College. Manson can be the Director of the large-scale VITAL trial of omega-3s.
