Knowing your Omega-3 levels can be life changing but also life saving.

Suppose you could, with precision, determine your personal risk for sudden cardiac death— but then reduce it substantially in a matter of weeks while also helping to extend your life span by 5 years…would you be interested?

What is the Omega-3 Index?(O3I)

The Omega-3 index is a biomarker that measures the combined percentage of two key long-chain omega-3 fatty acids—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—in red blood cell  membranes, expressed as a percentage of total fatty acids.

It was developed in 2004 by leading Omega-3 researcher Dr William S. Harris and German Cardiologist Dr. Clemens von Schacky.

The Omega-3 Index measures your omega-3 status in the body and a risk factor for cardiovascular disease (particularly fatal coronary heart disease), in the same way as HbA1c reflects long-term blood glucose control.

RISK CATEGORIES
  • ≥ 8%: Optimal / desirable (lowest risk zone for cardiovascular events).
  • 4–8%: Intermediate.
  • < 4%: Low / high risk.

How it's Measured

A blood sample (often a simple finger prick) analyses the fatty acid composition of red blood cell membranes.

It typically reflects average Omega-3 intake and tissue levels over the past 3–4 months (the lifespan of red blood cells).

Our Essential Test focuses specifically on EPA + DHA levels whereas the Advanced Test measures all 24 fatty acids in the blood and provides all the key ratios: Omega-3 Index, Omega-6 to Omega-3 ratio, AA:EPA ratio and the Trans Fat Index.

HOW TO TAKE A TEST

Why It Matters?

Heart Health

EPA and DHA are essential for cardiovascular health. They help reduce inflammation, lower triglycerides, and support healthy cholesterol levels. This triple-strength formula provides 3x more Omega-3s, delivering stronger protection for your heart.

Brain Function

DHA is crucial for brain function, improving memory and cognitive health. DPA further boosts the absorption and efficacy of DHA and EPA, ensuring your brain gets the nutrients it needs to stay sharp.

Joint & Mobility Support

Omega-3 fatty acids help reduce inflammation, making this supplement a powerful ally in promoting joint health and easing discomfort from stiffness.

All-round Wellness

Higher Omega-3 Index levels are associated with better heart health outcomes, and it may also support brain, eye, and joint health.
