Research

Most recently, a study published in Progress
in Lipid Research mapped the Omega-3
Index of people globally.

The results were shocking, leading researchers to conclude that:

…low and very low bloods levels observed for most of the globe are associated with an increased risk in cardiovascular related mortality… It is also highly likely that increased blood levels of EPA+DHA across the globe would reduce the risk of cognitive decline with normal aging…

  • ≤ 4%
  • 4 - 6%
  • 6 - 8%
  • > 8%

Studies reporting blood levels of the omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), were systematically identified in order to create a global map identifying countries and regions with different blood levels.

Study Abstract

Included studies were those of healthy adults, published in 1980 or later. A total of 298 studies met all inclusion criteria. Studies reported fatty acids in various blood fractions including plasma total lipids (33%), plasma phospholipid (32%), erythrocytes (32%) and whole blood (3.0%). Fatty acid data from each blood fraction were converted to relative weight percentages (wt.%) and then assigned to one of four discrete ranges (high, moderate, low, very low) corresponding to wt.% EPA+DHA in erythrocyte equivalents.
