Docosahexaenoic acid (22:6, DHA)
MetabolismDHA is a structural omega-3 fatty acid essential for brain, eye, and nerve function.
It is abundant in neuronal membranes and supports cell signaling.
Why this matters
Adequate DHA levels improve cognitive performance, visual acuity, and heart health. Low DHA is linked to inflammation, neurodegeneration, and mood disorders.
How this connects to other biomarkers
- Docosahexaenoic Acid is the principal omega-3 in brain and retinal phospholipids and contributes substantially to the Omega-3 Index.
- Low DHA with low Eicosapentaenoic Acid (20:5, EPA) and a low Omega-3 Index raises cardiovascular and cognitive risk; supplementation directly raises both DHA and EPA.
- Elevated DHA with normal EPA suggests algae- or supplement-derived intake rather than fish.
