This Omega-3 Test or Dr. Harris Was Featured On

How Do You Know You Are Taking Enough Omega-3s?
Listen to Dr. Harris, The Inventor of This Test.

The Omega 6/3 Ratio

If you are a Dr. Oz fan, you might have seen his show where he explored the Omega 6/3 ratio. But just in case a small refresher is needed: Both Omega-3 and Omega-6 are essential fatty acids; our bodies can’t make them, yet we desperately need them so we need to obtain them from food. Omega-3s, namely the most important EPA and DHA, are found in fatty fish or fish oil supplements. Omega-6s are abundant in the Western diet from safflower, corn, cottonseed, and soybean oils. Both 3s and 6s are healthy. But…
Yes, there is a “but”… we Americans get almost 70% of our Omega-6 from oils, shortening, and margarine and just 6% from beans, seeds, and nuts, 1% from eggs, and 13% from meat, poultry, and fish. So when we look at Omega-6 intake, we’re really talking about intake from french fries (cooked in vegetable oil), processed pastries (made with shortening), and processed high-sugar, high-fat junk food. Nearly all processed, packaged and restaurant foods contain these oils. Because they are cheap. We are what we eat, and who wants to be a french fry!
Insufficient intake of the long-chain Omega-3 fatty acids (DHA, EPA), together with skyrocketing consumption of Omega-6 fatty acids, is believed to be the cause of chronic inflammation, which is linked to various conditions.

Excess Omega−6s from vegetable oils interfere with the health benefits of Omega−3 fats, in part because they compete for the same rate-limiting enzymes.

Did you know, that over-the-counter and prescription anti-inflammatory drugs work by reducing the formation of inflammatory compounds derived from Omega-6s? If you were to simply limit your dietary intake of Omega-6 and increased your intake of long-chain Omega-3s, you would achieve very similar results.

The more Omega-3 fat you eat, the less Omega-6 will be available to the tissues to produce inflammation. In excess, Omega-6 is pro-inflammatory, while Omega-3 is neutral. A diet with a lot of Omega-6 and not much Omega-3 will increase inflammation. A diet of a lot of Omega-3 and not much Omega-6 will reduce inflammation.

The following information has been posted on National Library of Medicine site:

"Several sources of information suggest that humans evolved on a diet with a ratio of Omega 6/3 essential fatty acids (EFA) of approximately 1/1, whereas in today’s Western diets the ratio is 15/1 to 16.7/1 (some sources even cite 25/1). Western diets are deficient in Omega-3s, and have excessive amounts of Omega-6s compared with the diet on which human beings evolved and their genetic patterns were established. Excessive amounts of Omega-6 fatty acids and a very high Omega 6/3 ratio promote the pathogenesis of many diseases."

So How To Best Achieve the Proper
Omega 6/3 Ratio?

Either by reducing your Omega-6 intake, increasing Omega-3 intake, or preferably both (making no changes to your Omega-6 intake and increasing consumption of Omega-3s is not very wise).

What dose of Omega-3s do you need to take?
Get your Omega-3 levels tested, and your personal report will tell you how much Omega-3s you need to take to optimize your well-being.

"I read about the Omega-3 blood test in Dr. Sears' Omega-3 Effect, and also in Dr. Maroon's Fish Oil: The Natural Anti-Inflammatory. Being pregnant and nursing, I naturally wanted the best for both me and my kids. I'm so happy I took the test, one less thing to worry about!"

-- Tom

"In my golden years, knowing the best preventive practices is a must. The Purest Day Advantage 8: Your Omega-3 Levels Sufficiency Test showed me I needed to be more attentive about my Omega-3 and Omega-6 consumption."

-- Adrien

"In the comfort of my home, I recently took the Purest Day Advantage 8: Your Omega-3 Levels Sufficiency Test. Simple. Quick. Affordable. And now I don't need to presume any longer."

Standardized Method Of Analysis

The Omega-3 Index test, with its standardized method of analysis, is the base for over 80 scientific studies, and more than 40 scientific publications. It has been used by prestigious research groups around the globe, including the Nobel prize winner Elisabeth Blackburn, the Harvard Medical school, University of London, University of Berlin, the University of Seoul, and many others.

This test uses novel "dry blood spot" technology.

The Omega-3 Index is the result of Dr. William Harris’s 30 years of research in fatty acids and cardiovascular disease. The Omega-3 Index is a measure of Omega-3 fatty acids, EPA DHA, in red blood cells, which relates to risk for heart disease. A high Omega-3 index reduces risk for heart disease and sudden cardiac arrest. It also helps to maintain healthy brain, eye, and muscle function, as well as optimal mental and emotional health. You should know your Omega-3 index. It’s simple!

Why this Omega-3 test?

  • Over 1,000,000 people have measured their Omega-3 Index.
  • It has been used in large NIH-funded population studies.
  • It uses novel “dried blood spot” technology.
  • It's simple and safe: Only need 1 drop of blood!
  • It's hassle-free: Send dried blood spot through regular mail and receive results via email within 5 days of the lab receiving your sample.

Why measure your Omega-3 levels

  • Omega-3s are important for heart, brain, and joint health.
  • Most Americans have low levels of Omega-3s in their blood.
  • Low levels of Omega-3s are related to increased risk for fatal heart attack, depression, and possibly dementia.
  • Blood levels of Omega-3s can be improved by simple dietary changes.
  • The only way to know your blood level of Omega-3s is by measuring it.
