In previous posts, we have discussed what optimal omega-3 levels are by looking at the Omega-3 Index, and how to improve your Omega-3 Index. While the Omega-3 Index is often considered the most important measure for omega-3 status, it is also useful to know your status of other omega fatty acids, such as with the AA:EPA ratio and the Omega-6:Omega-3 ratio.

What is the AA:EPA ratio?

The AA:EPA ratio shows you your ratio of arachidonic acid (AA), considered the main pro-inflammatory omega-6 fatty acid, which is found in foods such as vegetable oils, butter, poultry and red meat, to eicosapentaenoic acid (EPA), a major anti-inflammatory omega-3 fatty acid found primarily in fatty fish. This ratio may serve as an indication of the amount of inflammation in the body over the last 3-4 months before testing.

What is the Omega-6:Omega-3 ratio?

The omega-6:omega-3 ratio is calculated by dividing the sum of seven different omega-6 fatty acids by the sum of four different omega-3 fatty acids. This ratio is a more general measurement of overall status of omega fatty acids in the body, and can be used as another measure for inflammation.

What ratios should I aim for, and how do I get there?

While the optimal ranges for health have not been established, the target range for the omega-6:omega-3 ratio is considered to be 3:1 to 5:1, and for the AA:EPA ratio, 2.5 to 11. Some experts consider an AA:EPA ratio of 1.5 to 3 to be low risk, 3 to 6 to be moderate risk, 7-15 to be elevated risk, and above 15 to be high risk. Evidence suggests that lower ratios are better for health. While a lower ratio of each correlates with a higher Omega-3 Index, it is possible to have an Omega-3 Index within a healthy range (recommended at 8% or greater), but have one or both of these ratios higher than desirable. Knowing your ratios can help you take more specific steps to achieve an ideal ratio status, mainly by increasing omega-3 intake with supplements and food (fatty fish) while also decreasing omega-6 intake. Doing this may not only improve your AA:EPA and omega-6:omega-3 ratios, but it will likely also improve your Omega-3 Index.

A recent review showed that, among GrassrootsHealth participants, 30% have an omega-6:omega-3 ratio of 5:1 or lower and 57% have an AA:EPA ratio of 11:1 or lower as shown on the chart below.

Remember to retest your omega levels approximately 4-6 months after making changes to your supplementation routine and/or diet to make sure those changes are helping you reach your target levels.

Do your ratios need improvement?

Do you know your AA:EPA and omega-6:omega-3 ratio levels? Make sure you know the status of these ratios by adding them to your Omega-3 Index test, and see if changes in your diet and supplementation could improve your overall omega status.
