Omega-3 Supplements May Reduce Risk of Cardiac Death

Cardiac death accounts for approximately two-thirds of all cardiovascular deaths in the US. A recent study suggests that taking omega-3 supplements may reduce the risk of cardiac death by an average 8%.


For their analysis, researchers examined data from 14 randomized, controlled trials that included a total of 71,889 people. All of the trials were longer than six months, examined cardiac death as the primary outcome, and compared frequencies of cardiac death events between omega-3 and control groups.


After examining the data, they found that taking EPA and DHA omega-3 supplements was associated with an 8% reduced risk in cardiac death. That number increased to 30% for people who took doses of more than 1 gram. They also found that for people with elevated triglycerides or LDL cholesterol, the reduction was 17%.


Researchers from Midwest Biomedical Research and the Johns Hopkins University School of Medicine conducted the study. It was published online ahead of print on August 2, 2017, in the Journal of Clinical Lipidology.


There are two types of omega-3s: DPA and EPA. Omega-3s have been linked to a number of health benefits, including improved mood, improved joint mobility, reducing the risk of age related macular degeneration, and aiding your immune system.


Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For people who don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.
