Omega-3s & Heart Health: Strong Science Supports Broad Recommendations

Broad medical recommendations, like those now advanced by the American Heart Association (AHA) and National Cholesterol Education Program, come only after extensive research has confirmed usefulness. Multiple types of research are used. Epidemiologic studies compare the difference in disease and diet across groups of people. Experimental studies assess the role of a nutrient or medication in laboratory animals. Clinical studies assess the impact when given to a test group of people. This impact is compared to a “control” group not taking the nutrient or medicine.

Omega-3s from fish oils have been subject to all types of studies, and the benefits associated with cardiovascular health and disease prevention have been consistently shown. As a result, leading medical organizations now recommend Omega-3s from fish oil for cardiovascular health. The recommendations include:

• 500mg/day of Omega-3s from fish oil for adults that have not been diagnosed with coronary artery disease.


• 1000mg (1g)/day for adults that have been shown to have coronary artery disease.


• 3000mg-4000mg (3-4g)/ day for adults with highly elevated triglycerides.

Omega-3s are not associated with reductions in LDL (bad) cholesterol levels. Yet, cholesterol alone is only part of the cause of heart disease. A number of other factors can determine the damage that cholesterol can do. Omega-3s appear to favorably affect these factors including decreased blood pressure, reduced inflammation that leads to plaque formation, and the stabilization of existing plaque.

How significant is the impact on Omega-3s? Studies have indicated as much as a 18-20% reduction in a cardiovascular event such as a heart attack for healthy adult. For those with a history of heart disease, the impact has been shown at least as significant, and perhaps higher.

Omega-3s from fish oil represent an important component of an integrated and comprehensive nutritional approach to cardiovascular health. Other broad recommendations include the consumption of 10+ grams/day of selected soluble fibers such as those from oats, beans, barley and psyllium, 2 grams/day of plant sterols, and diet that restricts saturated fats, trans fats and dietary cholesterol.
