The fatty acid profile is one of the most underestimated markers in functional medicine. An imbalance between omega-6 and omega-3 drives systemic low-grade inflammation that sustains chronic pain, cardiovascular risk and autoimmune conditions — without appearing in standard blood work.
Fatty acids in red blood cells reflect the past 90 days of dietary intake and cell membrane status. An omega-3 index below 8% is an independent risk factor for cardiovascular disease. The AA/EPA ratio measures the inflammation balance at the cellular level.
Elevated arachidonic acid (AA) and low EPA indicate a pro-inflammatory cellular environment that undermines all downstream protocols. The fatty acid profile determines whether omega-3 supplementation is indicated — and at what dose — before other interventions are initiated.
