Omega-6/Omega-3 Ratio
The omega-6 to omega-3 ratio compares intake and circulating levels of pro-inflammatory-leaning omega-6 fats with anti-inflammatory omega-3 fats. Typical Western diets produce ratios of 15:1 or higher, while ancestral and Mediterranean-style diets are closer to 2:1 to 4:1. Lower ratios are associated with lower inflammation and cardiovascular risk in observational studies.
Optimal range: who says what
Institutions, researchers and practitioners draw the line in different places. Each position is listed with who holds it and, where a document states it, a link. How we verify ranges.
- Institution or study4:1 or lowerSimopoulos 2002 review (Biomed Pharmacother); typical Western diets run far higherA 4:1 ratio was associated with a 70% drop in total mortality in secondary cardiovascular prevention
- Lab reference intervalNo established lab reference interval (calculated ratio)What a lab report flags against. A lab interval is not an optimal target.

Why Omega-6/Omega-3 Ratio matters
A lower ratio is associated with reduced inflammation and lower cardiovascular risk. The typical Western diet produces a high ratio (15:1-17:1); optimal is closer to 2:1-4:1.
Which Providers Test Omega-6/Omega-3 Ratio?
Blueprint is both the cheapest ($365/year) and the most comprehensive (100+ biomarkers) panel that includes Omega-6/Omega-3 Ratio.
2 panels that include it, cheapest first
| Provider | Annual Cost | Total Biomarkers | $/Biomarker |
|---|---|---|---|
| $365 | 100+ | $3.65 | |
| $499 | 100+ | $4.99 |
$/Biomarker is annual cost divided by the panel's advertised biomarker count, not the price of this one test. We track 23 blood test providers (32 plans); 21 of those plans are itemized marker by marker. Compare all of them.
