Arachidonic Acid / EPA Ratio
The AA/EPA ratio compares arachidonic acid, an omega-6 precursor of pro-inflammatory eicosanoids, with EPA, a precursor of anti-inflammatory mediators. A high ratio indicates a pro-inflammatory fatty acid balance typical of Western diets, while a lower ratio suggests better inflammatory balance. It can be lowered by reducing omega-6-rich oils and increasing EPA intake.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Arachidonic Acid / EPA Ratio. How we verify ranges.
- No stated targetNo separate optimal establishedLower ratios reflect more EPA relative to arachidonic acid; no validated target exists
- Lab reference intervalTarget: <3:1, Ideal: 1.5-3:1What a lab report flags against. A lab interval is not an optimal target.

Why Arachidonic Acid / EPA Ratio matters
Reflects inflammatory balance. High ratio indicates pro-inflammatory state. Target lower ratios through omega-3 supplementation and diet.

Frequently Asked Questions
What is the optimal range for Arachidonic Acid / EPA Ratio?
No separate optimal established: Lower ratios reflect more EPA relative to arachidonic acid; no validated target exists. Lab reference interval: Target: <3:1, Ideal: 1.5-3:1. That is what a lab report flags against, not an optimal target.
Which blood test providers include Arachidonic Acid / EPA Ratio?
4 of the 21 blood testing panels we itemize marker by marker include Arachidonic Acid / EPA Ratio in their panels. This biomarker has limited availability.
