Omega-3 Index: The “Cholesterol” Test for the 21st Century

Optimal blood levels of omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are a worldwide rarity. Only places where fish is consumed virtually every day (like Japan and Greenland) are average Omega-3 Index levels in the desirable range (8%-12%). In the US, over 95% of the population have suboptimal levels of omega-3.

 

What does this imply about the health of these low Omega-3 Index populations? It means higher disease burden and shorter lifespans. 

What is the Omega-3 Index?

The Omega-3 Index test is a blood test requiring only 1 drop of blood that is collected onto specially-treated filter paper and mailed to the laboratory for analysis. It is the amount of EPA+DHA in the red blood cell membrane (omega-3s like to hang out in membranes all over the body) and it’s expressed as a percent. The optimal range is 8% to 12%, but most adults not eating a lot of fish have levels between 3% and 6%.

How can I raise my Omega-3 Index?

Why are most people’s Omega-3 Index levels so low? Very simply because the dietary intake of EPA+DHA is too low. The only way to raise the Omega-3 Index is to eat more omega-3s, whether from fish and seafood or from EPA+DHA supplements. The latter can be oils derived from fish, krill, calamari, green lip mussel and/or certain strains of algae.

If you choose to take a supplement, it’s important to take them with food for best absorption. Most people need to take 500 to 1000 mg of EPA+DHA (not just “oil”) per day – and do so for several months – to get into the desirable range.

Is the Omega-3 Index test the new "cholesterol" test?

In many ways, the Omega-3 Index test can be likened to a cholesterol test. Both tests measure levels of compounds in the blood that are known “risk factors” for major chronic conditions like heart disease.

A high cholesterol level is bad whereas a low Omega-3 Index is bad. Another similarity is that because you can’t “feel” a high cholesterol level or a low Omega-3 Index, the only way to know your status is to do a blood test. But here the similarities end.

 

There are two major differences between cholesterol and the Omega-3 Index:

 1) In order to optimize your cholesterol level you typically need to take a drug (like statins, which can have significant side effects), whereas to optimize your Omega-3 Index all you need to do is change your diet and/or start taking omega-3 supplements which are completely safe; and

2) The Omega-3 Index is a better predictor of risk for heart disease and even premature death than is cholesterol. This was the conclusion of a major study we recently published from the Framingham Heart Study. Briefly, we found that people (average age 66) with the highest Omega-3 Index levels were 35% less likely to die from any cause in the ensuing 7 years than people with the lowest Omega-3 Index levels. But the same was not true of cholesterol – there was no difference in risk for death in people who had the lowest vs the highest cholesterol levels.

This is not to say that maintaining a healthy cholesterol level is not important – it absolutely is – but if you or your doctor are going to monitor your cholesterol levels, then you should also measure your Omega-3 Index.  

In the late 20th century, the medical world focused on “knowing your number” and by that they meant your cholesterol level. Now, well into the 21st century, a new marker deserves your attention – the Omega-3 Index.
