Old research found a link between fish oil and its benefits for heart problems.
According to these studies, taking it reduces the risk of cardiovascular disease.
For many years, the American Heart Association recommended eating two fish a week.
And in 2017, the team also suggested that supplemental fish oil may slightly reduce the risk of heart failure or cardiac death.
However, a recent study, discussed late last week at the Heart Heart Association’s scientific sessions, found that fish oil supplements “don’t really help promote heart health,” CNN reported.
The team overseeing the study explained that the results have no “benefits of putting fish oil or vitamin D in heart health.”
A second study, published in the Journal of the American Medical Association on Sunday, found that omega-3 fatty acid supplementation does not reduce the risk of cardiovascular disease.
Dr. Steve Nissen, a cardiologist at the Cleveland Clinic who worked on the study, said:
“Multiple tests now have not shown the effect of fish oil on the heart and blood vessels.”
“In fact, fish oil may not be neutral, as in some cases it becomes harmful,” he added.
