The AA/EPA ratio directly measures the balance between the primary pro-inflammatory omega-6 (arachidonic acid) and the primary anti-inflammatory omega-3 (EPA) in cell membranes, making it one of the most sensitive indicators of inflammatory status in the body. A high ratio indicates that pro-inflammatory signalling dominates; a target below 3:1 is optimal for cardiovascular and inflammatory disease prevention. This ratio responds meaningfully to EPA-rich omega-3 supplementation within 3–4 months, making it a reliable treatment monitoring tool.
Also known as: Acido araquidónico/Eicosapentaenoico, Arachidonate/eicosapentaénoate, Arachidonato/Eicosapentaenoato, C20:5w3, Eicosapentaenoic acid, EPA, Icosapentaenoate, Timnodonate
A high AA:EPA ratio above 10 indicates a strongly pro-inflammatory fatty acid profile. A low ratio below 3 reflects effective omega-3 supplementation.
Optimal is 1.5:1 to 3:1. EPA supplementation of 2-3 g/day typically normalizes the ratio within 8-12 weeks.
