Knowing your omega-3 levels is important.
Omega-3 intake is notably low worldwide, and this is a major public health issue. In the U.S. 95+% of Americans do not get enough EPA and DHA to be cardioprotective.
Why does it matter?
A 2016 study looked at the Omega-3 Index, which is the combined percentage of the omega-3 fatty acids EPA and DHA in red blood cell membranes, in adults around the world. The results can be found in the map to the right, which shows omega-3 blood levels by country.
The areas in red identify countries with extremely low blood levels of omega-3. Americans are generally in the area of 4% or lower. Research is now showing a correlation between these blood levels and health outcomes.

Risk for fatal coronary heart disease was 35% lower in persons with an Omega-3 Index of 8% compared to those with an index of 4%. (Harris 2017)
