CHARLESTON, SC (WCBD) – An international clinical study found that prescription fish oil may not help your heart.
Steven Nissen, MD, is a cardiologist at the Cleveland Clinic and led the research team.
“A very high dose of a very strong fish oil, a very potent fish oil, did not reduce the risk of heart attack, stroke or death,” said Dr. Nits.
“That was the really important outcome of the process. Fish oil simply has no cardiovascular benefit. ”
The researchers looked at data from more than 13,000 people around the world who were treated with a statin, which lowers cholesterol levels in the body.
That means they are also at a higher risk of having a major heart event like a heart attack or stroke.
Participants received either a high-dose prescription fish oil or a placebo with corn oil. Ultimately, the researchers found no significant reductions in heart attack, stroke, or death in people who took high-dose fish oil.
Those in the fish oil group were 69 percent more likely to develop an irregular heartbeat.
Dr. Nissen said the medical community needs to take another look at how fish oil is prescribed.
“I am actually concerned that fish oil is being used very widely with no evidence of very good benefit, and I think we have to address this issue.”
Remember, it is important to speak to your doctor before taking or stopping any medication, including over-the-counter supplements.
