Increase omega-3 index

What this outcome means

The omega-3 index reflects how much EPA and DHA are stored in your red blood cell membranes, a stable marker of your long-term omega-3 status. On DoseRank it maps to a defined health outcome built from human studies on red blood cell EPA+DHA percentage, omega-6 to omega-3 ratios, and membrane fatty acid composition – data sourced from open sources and specialized resources. DoseRank is not medical advice.
