Add-on · Nutrition and heart health
An omega-3 index test measures the EPA and DHA in your red cell membranes, a reflection of your omega-3 intake over the last few months. An index of 8% or more is linked to the lowest heart risk, and most people in the UK run well below it. You can add the full omega-3/6 profile to TrueVitals Ultimate for £129.
Add-ons are tested on the same blood draw as your panel and reported inside your clinician-reviewed report, read alongside your other 140 results. They are not sold on their own.
Pay in instalments with Klarna or Clearpay at checkout. Want it with Advanced instead? Email support@truevitals.co.uk and we will set it up.
EPA and DHA are the long-chain omega-3 fats found mainly in oily fish. They are built into the membranes of every cell, including red blood cells, which live about four months. Measuring the percentage of EPA and DHA in red cell membranes gives a stable picture of your intake, unaffected by your last meal.
The profile also reports your omega-6 to omega-3 balance (the AA:EPA ratio) and trans fat levels.
Ultimate already measures your cholesterol, triglycerides, ApoB and hs-CRP. The omega-3 profile adds what those cannot show: whether your diet is supplying the fats that support heart and brain health. A low index with high triglycerides is a particularly useful combination to know about.

Be realistic about what it does: the omega-3 index is a nutrition and risk marker, not a diagnosis. If you are on blood thinners, check with your doctor before starting high-dose fish oil.
A private panel is a good way to get a baseline, understand a result in context and track it over time. It does not replace your GP for symptoms, and anything that needs follow-up is flagged in plain words in your report.
8% or more is the range linked with the lowest heart risk. Under 4% is linked with the highest.
The omega-3/6 profile is processed by a specialist lab, so results follow 1 to 3 weeks after your main Ultimate report. We add them to your report when they arrive.
Not for the omega-3 index, as it reflects months of intake. Ultimate includes fasting insulin and glucose, so an overnight fast is still advised.
No. Keep taking it as normal. The point is to see whether your current intake is getting you to target.
Not as standard. It is an add-on to Ultimate.
