The way that omega-3 fatty acids reduce CVD risk is still not known and is still being studied. Large-scale epidemiologic studies suggest that people at risk for coronary heart disease benefit from consuming omega-3 fatty acids from plants and marine sources. Research has shown the following:
- Decrease risk of arrhythmias, which can lead to sudden cardiac death
- Decrease triglyceride levels
- Decrease growth rate of atherosclerotic plaque
- Lower blood pressure (slightly)
How much each person should take is still unclear. Studies suggest taking EPA+DHA ranging from 0.5 to 1.8 grams per day (either as fatty fish or supplements) significantly reduces deaths from heart disease and all causes. Total intake of alpha-linolenic acid should be 1.5-3 grams per day to be beneficial.
More studies are needed to confirm and define the health benefits of omega-3 fatty acid supplements for preventing a first or subsequent cardiovascular emergency.
The American Heart Association recommends most to increase omega-3 fatty acid intake through foods. Coronary artery disease patients may not be able to get enough omega-3 by diet alone. They may want to consult with their doctor about taking a supplement.
The American Heart Association also feels supplements could help people with high triglycerides. Your physician will be able to decide what dosage is right for you.
Always keep in mind to look for a high-quality omega-3 fatty acid supplements, free of contaminants before using.
