Optimal Range:8-12 %
What is Omega-3 Index?
The Omega-3 Index measures the percentage of EPA and DHA (omega-3 fatty acids) in your red blood cell membranes. It reflects your omega-3 status over the past 3-4 months.
Why Omega-3 Index Matters
The Omega-3 Index is one of the most validated longevity biomarkers. An index above 8% is associated with the lowest risk of sudden cardiac death, cognitive decline, and all-cause mortality. It's modifiable through diet (fatty fish) and supplementation, making it an actionable health target.
Symptoms of Low Omega-3 Index
- Increased cardiovascular risk
- Depression and mood issues
- Cognitive decline
- Dry skin and eyes
- Joint inflammation
- Poor wound healing
Symptoms of High Omega-3 Index
- High is optimal (cardioprotective)
- Very high (>12%) rarely causes issues
- Theoretical increased bleeding risk at extreme levels
