    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
