Why Test?

How much omega-3 you eat is only part of the puzzle. There are many other factors that effect your Omega-3 Index such as:


Don't guess when you can test.


How it Works

Simple finger poke. No blood draw needed. Collect your sample at home.

step 1


Choose the test service you would like. The sample collection kit is the same for all services and typically arrives in 3 to 5 days.

step 2

Collect Sample

Follow the simple kit instructions to collect your sample from the comfort of home. Once you have your sample collected mail it back to our lab with the pre-paid envelope.

step 3


In 1-2 weeks you will receive an email letting you know your personalized results are ready.

Research shows higher omega-3 blood levels are beneficial.


Seattle Primary Cardiac Arrest Study

University of Washington Patients who were having a primary cardiac arrest were much more likely to have low Omega-3 Index than healthy subjects.

The Omega-3 Index and Risk for Fatal CHD

Stanford Univeristy Data from 10 prospective cohort studies including >24,000 subjects showed that an Omega-3 Index of 8% or greater was associated with the lowest risk for fatal CHD.

Total Mortality and the Omega-3 Index: Heart and Soul

University of California San Francisco People with the highest Omega-3 Index levels lived longer than those with the lowest levels.

The Omega-3 Index, Brain Size and Cognitive Function: Framingham Heart Study

Framington Heart Study Participants in the Framingham Heart Study with the lowest Omega-3 Indexes had smaller brain volumes and performed worse on mental function tests.

Depression and the Omega-3 Index

Ludwig Depressed patients had an Omega-3 Index 24% lower than healthy controls.

Greater Longevity with a Higher Omega-3 Index

Women's Health Initiative Postmenopausal women with an Omega-3 Index over 8% were 30% less likely to die than those with an Index under 4% over 15 years.

Recovering from a Heart Attack with Omega-3s: The OMEGA-REMODEL Study

Harvard Patients who had recently had a heart attack and were then treated with omega-3 fatty acids for 6 months had healthier hearts if their Omega-3 Index reached less than 11% than those who did not take omega-3s.

How can I increase my Omega-3 Index?

Your Omega-3 Index Basic test gives you a snapshot of the fats that make up your cells. Some fatty acid levels, such as the Omega-3 Index, are closely related to what you eat while others are more affected by your metabolism. Below we provide some information about how to improve you Omega-3 Index through diet. Also, use the Omega-3 Index Calculator for a personalized recommendation for EPA+DHA intake based on your Omega-3 Index. For more detail, see Increasing Your Omega-3 Index: Part 1 and Part 2.


The Dietary Guidelines for Americans recommends 2 servings of fish per week (see Table below), averaging out to 250 mg/day EPA+DHA. Other countries, such as Canada and Australia, recommend 400-500 mg/day EPA+DHA. The FDA has also ruled that intakes of up to 3,000 mg/day of EPA+DHA combined from foods is “Generally Recognized As Safe (GRAS)” and may be consumed without concern of adverse effects by all adults. There are also recommendations for specific health conditions, such as:

  •  Patients with coronary heart disease – 1,000 mg/day EPA+DHA
  • Patients with high triglycerides – 3,000-4,000 mg/day EPA+DHA

Fish oil supplements are a safe and potent source of EPA+DHA. The source and form of the omega-3s in the supplements affect how well you absorb the omega-3s, as well as whether or not you take them with food. There are also vegan/vegetarian supplements which contain omega-3s produced by algae and yeast. It is important to look at the label for the amount of EPA+DHA, specifically, that the supplement contains. For example, many supplements are 1,000 mg of fish oil but only contain 300 mg of EPA+DHA. There are some examples of the EPA+DHA levels in supplements included your report.

Omega-3 Index Calculator
You may need to maintain the recommended EPA+DHA intake for 4-5 months in order to meet your goal Omega-3 Index.



Use the estimate from the calculator to make a plan to increase your EPA+DHA intake. For example, the calculator may recommend you take 1235 mg EPA+DHA per day and to meet that goal you may take 1500 mg EPA+DHA per day because of the amount in your supplements. It is not necessary to match the calculated dose exactly.

While EPA+DHA intake is the primary driver of your Omega-3 Index, your genes and overall health can affect the Omega-3 Index response to dietary changes. Re-testing is the only way to determine whether you have achieved your target Omega-3 Index.

These calculations are based on results from a 5-month randomized, placebo-controlled fish oil supplementation study in 115 healthy individuals (Flock M et al. JAHA 2013).


Fish is the best dietary source for the omega-3s, EPA+DHA. Dietary intake of EPA+DHA directly influences Omega-3 Index.  “Fatty,” “oily,” and “cold-water” are terms used to describe fish with higher levels of EPA+DHA. A full list of fish and their EPA+DHA levels is included in your report. There are also useful websites to help guide your fish decisions.

Plant Omega-3s

Plant-sources of omega-3s, such as walnuts, flaxseed oil and chia or flaxseeds, contain the omega-3 ALA. To a small extent, this omega-3 can be converted into EPA (and to an even smaller extent, DHA) in the body, but it is much less effective at raising Omega-3 Index levels when compared to taking pre-formed EPA+DHA. Plant-based omega-3 sources are still healthy food choices, but they will not raise your Omega-3 Index.
