Just as with vitamin D deficiency, omega-3 deficiency can put you at risk for chronic disease. Both are essential to your everyday health.

You may already have an idea of how your vitamin D level may affect your health…

Omega-3 Deficiency is Common Around the World

The typical diet for most individuals, up to 80-90% in some countries, does not provide enough EPA and DHA to provide these benefits, leaving a majority of the population deficient – with most countries and regions around the globe having Omega-3 Index levels that are considered low to very low.

The Importance of Testing Omega-3s (just as with vitamin D!)

By taking simple dietary steps like increasing your consumption of foods or supplements rich in the omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), your Omega-3 Index will rise.  However, similar to vitamin D serum level response to supplementation, there is a wide variation in response between omega-3 intake and a resulting Omega-3 Index level; there is no way to tell if you are getting enough omega-3s unless you test your levels.

What Does the Omega-3 Index Test Measure?

The Omega-3 Index is a blood test that measures the amount of omega-3 fatty acids (EPA and DHA) in red blood cell (RBC) membranes and is expressed as a percent of total RBC fatty acids. It is a long-term and stable marker of omega-3 status, and it reflects tissue levels of EPA+DHA.


An Omega-3 Index of over 8% is associated with the lowest risk of death from heart disease and below 4% with the highest.

Be a force for change in your health and the healthcare system…

IDENTIFY: You can’t know if your vitamin D level or Omega-3 Index is optimal just because you eat the right foods or take supplements – they both must be measured.


CORRECT: Once you know your vitamin D level and Omega-3 Index, they can be optimized with simple dietary and lifestyle changes.


MAINTAIN: Testing your vitamin D and Omega-3 Index every 4-6 months ensures that levels stay optimal.
