The Benefit of
Omega 3 Fatty Acids

For Sudden Cardiac Death

Omega 3 Fatty Acids Offer a Pleasant Surprise to Researchers

In spite of the large body of evidence supporting the view that a healthy diet can drastically improve heart health, researchers are constantly surprised by their findings.

It has long been known that the omega 3 fatty acids in a fish oil supplement can help reduce incidence of heart disease including atherosclerosis and heart attack. 

But the research also demonstrates that omega 3 fatty acids reduce the heart arrhythmias that lead to sudden cardiac death (SCD). To demonstrate this we will look at just two studies.

  • The first study collected data concerning the amount of fish a patient consumed in relation to the incidence of SCD.
  • The second study was similar except it evaluated consumption of omega 3 via a fish oil supplement regardless of diet.

Fish Eaters Have Lower Average Heart Rate

In the largest study of its kind researchers discovered that men who eat fish have a lower average heart rate than men who do not. Why is this important? Because… 

Increased heart rate is a risk factor in sudden cardiac death even when no other coronary heart disease is apparent

Why is this so? Because… 

When the electrical impulses that control heart rhythm become rapid or chaotic the heart may suddenly stop (arrest). Death normally follows quickly in the absence of immediate emergency care. Omega 3 fatty acids found in cold water fish like…

  • Mackerel
  • Tuna
  • Salmon
  • Herring, etc.

… may help prevent this sudden cardiac arrest by controlling the electric impulses that regulate heartbeat. 

The first study included… 

… 9,758 men from Lille, France and Belfast, Ireland between the ages of 50 and 59 who were free from coronary heart disease. These men answered questions about their diets and other lifestyle habits. Blood samples were also taken to determine cholesterol and triglyceride levels. 

A small subset (407 men) was tested to determine blood levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two prominent omega 3 fatty acids. The men were divided into groups according to the amount of fish they consumed on a normal basis.

  • 27% ate fish less than once per week.
  • 47% ate fish once per week.
  • 20% had fish twice per week
  • 6% ate fish more than twice per week.

Adjusts were made for…

  • Age
  • Location
  • Education level
  • Physical activity
  • Smoking
  • Alcohol consumption…
The findings were encouraging
  • The average heartbeat for men who ate fish less than once per week was 67.5 beats per minute.
  • Those who ate fish more than twice per week had an average heartbeat of 65.6 beats per minute.

Average heart rate decrease was consistent over the four groups indicating that the amount of omega 3 fatty acids in one’s diet has a profound effect on heart rhythm.

Even a small reduction in heart rate can make a significant impact especially if abnormal heart rhythms (arrhythmias) are also reduced.

Here’s a question for you…

Are you sick and tired of just not feeling great?

Are there health issues – in addition to your heart health – that concern you? Like…

Anxiety? Or not sleeping well? Or joint pain? Or low energy? Or poor digestion? Or weight gain? Or stress? Why do so many people suffer from these symptoms and others? Those nagging health issues that seem so difficult to define.

Did you know that these health problems – as well as more serious chronic diseases – can be the result of …

  • Your body holding on to too many toxins?
  • And chronic inflammation?
  • And pH and blood sugar imbalance?
  • And your elimination organs not working well?
  • And poor nutrition?
  •  And foods that stress your system?

Taking a Fish Oil Supplement Can Help Reduce Risk of SCD

The second study, based on an analysis of data from the GISSI-Prevenzione trial, was particularly concerned with the consumption of omega 3 fatty acids consumed in a fish oil supplement. 

The study found that 1-gram of n-3 polyunsaturated fatty acids (PUFA) - also known as omega 3 fatty acids significantly reduced the risk of sudden death especially in those who had a heart attack. 

In this study, researchers enrolled 11,323 patients throughout Italy who had suffered recent heart attacks and randomized them into four groups as follows. Omega 3 was consumed by taking a fish oil supplement.

  • 2,835 patients received 1 gram of n-3 PUFA
  • 2,830 received 300 milligrams of vitamin E
  • 2,830 participants took the n-3 PUFA and vitamin E.
  • The remaining participants took a placebo.

It was found that the patients treated with the omega 3 fatty acids via a fish oil supplement exhibited a significantly lower mortality (1.1 percent vs. 1.6 percent) in the three-month period following the initial heart attack than those who did not take the supplements. 

The risk of death, and sudden death, is highest in the first months following a heart attack. It was precisely during this follow-up period that the fish oil supplement was tested. 

The test analysis revealed that there was a 42% reduction in sudden cardiac deaths within the three-month period following a heart attack compared to patients who received no omega 3 fatty acids. 

By the end of the 42-month follow-up period the death rate was at 8.4 % among the participants who had received the fish oil supplement and 9.8% among those who had not received the fish oil supplement, demonstrating that the supplement group received lifesaving benefits beyond the initial 3-month danger period. 

Analysis of the data further showed that the benefits of the omega 3 fatty acids (n-3 PUFA) is most likely due to reducing potentially fatal arrhythmias, the most common cause of sudden cardiac death.


The importance of this study is made clear when one considers that there is no effective therapy for arrhythmias. The importance is further noted because in the study all the participants ate the same healthy diet (Mediterranean diet) including fruits, vegetables, olive oil and fish. 

Yet the patients taking the omega 3 fatty acids in the fish oil supplement had significantly fewer deaths than those who did not

It is not clear how n-3 PUFA (omega 3) protects the heart. However whatit does is clear. It regulates the electrical activity of cells in the heart muscles making them resistant to arrhythmias. Therefore, the research shows that in addition to eating a heart healthy diet including fish, fruits, vegetables and whole grains, taking a fish oil supplement containing omega 3 fatty acids can help reduce the risk of sudden cardiac death.
