The X Fact What is the omega-3 index? reported on a paper we published on April 22nd, 2021 that after following 42,000 people for 16 years, we showed that individuals with the highest EPA and DHA levels compared to the lowest levels measured, had a 13% lower risk for death from all causes during the follow up period.

Furthermore, when we looked at three major causes of death – cardiovascular disease, cancer and all other causes combined – we found statistically significant risk reductions (again comparing the 90th vs 10th percentile) of 15%, 11%, and 13%, respectively. The range between the 10th and 90th percentile for EPA+DHA was (in terms of red blood cell membrane omega-3 levels, i.e., the Omega-3 Index) about 3.5% to 7.6%. From other research we find that an optimal Omega-3 Index is 8% or higher. So the Omega-3 Index is an important predictor of risk for what is obviously the worst “health” outcome – death.
