Your Omega-3 Index

What is the Omega-3 index?

The Omega-3 index is a biomarker that measures the amount of EPA and DHA, the two most important omega-3 fatty acids, in the membrane of your red blood cells. The Omega-3 index is typically expressed as a percentage of the total amount of fatty acids in red blood cell membranes. For example, if you had 100 fatty acids and 8 of them were EPA and DHA, your Omega-3 index would be 8%.

How much Omega-3 do I need?

One of the most common questions among those interested in omega-3 fatty acids is, "How much do I need?" However, this is also one of the most challenging questions to answer. Unlike nutrients such as vitamin D or calcium, there is no universally agreed-upon daily dosage for EPA and DHA, making it difficult to establish a standard recommendation for omega-3 intake.

Health professionals provide advice based on various factors, including an individual's age, health condition, dietary needs, and current research findings.

Omega-3s are essential to support heart⁵, brain⁶ and vision⁶, playing an important role in well-being throughout one's life. A growing body of research suggests an individuals Omega-3 index should be above 8%¹ but recent studies show the average in UK consumers blood is just 5.5%².

How long it will take for me to get my Omega-3 index from 5% to 8%?

For the average UK person, it would take around 3 months daily intake of 1g Omega-3 of combined EPA and DHA to reach the 8% Omega-3 index levels; that’s 1 month of supplementation needed per 1% increase required³. To sustain this index, you will need to maintain the same diet and supplementation habits.

In order to help you determine what your Omega-3 index could be, we have designed a simple questionnaire. Please answer the questions below. The number assigned to your answer corresponds to points. Add up each number selected per question and check your total against the final scoring system at the end of the questionnaire.
