The Omega-3 Index is a measurement of the amount of the EPA and DHA in red blood cell (RBC) membranes. EPA and DHA, which are found in fish and shellfish as well as some omega-3 supplements, are long-chain omega-3 fatty acids that have been linked to numerous health benefits. Studies have shown that an Omega-3 Index at or above 8% is optimal and less than 4% is deficient, particularly for cardiovascular disease. In this blog we will highlight some of these studies.

Coronary heart disease mortality

Studies have found a decreased risk of coronary heart disease (CHD) mortality for those with higher Omega-3 Index measurements. Specifically, Harris et al. found that the Omega-3 Index associated with the lowest risk of death from CHD was 8% or higher and the index associated with the highest risk was less than 4%. Additionally, a meta-analysis of 10 cohorts found that the risk for fatal CHD was approximately 35% lower for those with an Omega-3 Index of 8.3% compared to those with an Omega-3 Index of 4.2%.

Acute coronary syndrome

Acute coronary syndrome (ACS) is caused by decreased flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. A study by Block et al. found that those with an Omega-3 Index of 8% of higher had a 69% lower risk for an ACS event compared to those with an Omega-3 Index of less than 4%.

Death from any cause

There is also evidence for a lower risk of death from any cause with higher Omega-3 Index. In the Framingham Offspring Study there was a 34% lower risk for an Omega-3 Index of 7.8% vs. 3.7%. In the Women’s Health Initiative Memory Study there was a 31% lower risk for an Omega-3 Index of 8% or higher compared to less than 4%.

Further, an Omega-3 Index in or near the optimal range of 8-12% has been linked to better cognitive function, improved arthritis symptoms, and improved depressive symptoms.
