The Omega-3 Index measures the percentage of EPA and DHA omega-3 fatty acids in your red blood cell membranes. Unlike a simple blood level, the index reflects your average omega-3 intake over the past 2–3 months. An index of 8% or higher is associated with the lowest cardiovascular risk, while below 4% is considered high-risk. Low omega-3 levels are linked to inflammation, depression, cognitive decline, and increased risk of sudden cardiac death.

5 biomarkers tested
Your Omega-3 Index results will include values for each of the 5 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 7–10 business days.
