Analysis of 11 fatty acid biomarkers
Processed by a UKAS-accredited UK laboratory. Results returned in 10–21 days of receipt.
Virtual consultation with a clinical pharmacist
Once your results are ready, our clinical team walks you through your fatty acid profile and what it means for your long-term health.
This test is ideal if you:
- Want to understand your inflammatory balance and how it affects your long-term heart health
- Have a diet high in processed foods, vegetable oils, or low in oily fish
- Want to monitor the impact of Omega-3 supplementation or dietary changes
- Prefer private, convenient, and expert-led health insights from home
- Are 18 years or older — this test is available worldwide
The test measures all 11 fatty acids as a percentage of total fatty acids, plus 6 calculated health markers.
- Palmitic acid (C16:0) — Saturated fat. Assessed in the context of cell membrane rigidity.
- Stearic acid (C18:0) — Saturated fat. Used to calculate cell membrane fluidity.
- Oleic acid (C18:1, Omega-9) — Monounsaturated fat with heart-protective effects when in balance.
- Linoleic acid (C18:2, Omega-6) — The most abundant Omega-6 in the diet. High intake linked to pro-inflammatory states.
- Alpha-linolenic acid (C18:3, Omega-3) — Plant-based Omega-3, precursor to EPA and DHA.
- Gamma-linolenic acid (C18:3, Omega-6) — Omega-6 with some anti-inflammatory properties when in balance.
- DGLA (C20:3, Omega-6) — Used to calculate Omega-6 ratio and Protection Value.
- Arachidonic acid / AA (C20:4, Omega-6) — Most important Omega-6 for the body. Key driver of inflammation. Optimal range: 6.5–9.5%.
- EPA (C20:5, Omega-3) — Primary anti-inflammatory Omega-3. Dominant in blood, muscles and tissues.
- DPA (C22:5, Omega-3) — Intermediate Omega-3 between EPA and DHA.
- DHA (C22:6, Omega-3) — Essential for brain, heart and eye health. Dominant structural fat in the brain.
Six health markers are calculated from these values: Omega-3 Index · Omega-6:3 Balance · Protection Value · Cell Membrane Fluidity · Mental Strength · AA Index.
- No fasting required — this test can be taken at any time of day.
- Avoid taking Omega-3 supplements for 24 hours before your test for the most accurate baseline result.
- Take your sample between Monday and Thursday to avoid postal delays over the weekend.
- Stay well-hydrated the day before to help blood flow easily.
- You will need a postal stamp to return your sample — available from any post office or supermarket.
- Results take 10–21 days to be returned once your sample reaches the laboratory.
- Read the kit instructions carefully before starting. Our team is here to support you if needed.
