EPA + DHA (%)

Combined EPA and DHA

Included in Complete.

The two omega-3s most studied for heart health.

EPA + DHA adds your two main marine omega-3 fats together as a percentage of all fatty acids measured. It's calculated from your EPA and DHA results and mostly reflects how much fish, seafood, or omega-3 supplement you consume.

It's related to the Omega-3 Index, with one important difference.

The Omega-3 Index is a specific test that measures EPA plus DHA in red blood cell membranes using a standardized method. Much of the research on omega-3 levels and heart risk uses that measure.

Your EPA + DHA result follows the same idea. Values can differ with the sample type and lab method, though, so they may not line up directly with published Omega-3 Index numbers.

The omega-3s are the same, but the method behind the number matters.

Questions

What does a lower EPA + DHA result mean?

It usually reflects low intake of fatty fish or omega-3 supplements. In observational research, higher EPA and DHA levels have been linked with lower risk of death from coronary heart disease. A clinician can help you decide whether changes make sense for you.

Can plant omega-3s raise my EPA and DHA?

They raise them only a little. The body converts a small share of ALA, the omega-3 in flaxseed, chia seeds, and walnuts, into EPA and DHA. Fish, seafood, and supplements containing EPA and DHA are the practical sources.
