What does the Omega-3 Index measure?

It measures EPA + DHA as a percentage of the fatty acids in your red blood cells. The optimal range is 8–12%.

When should I retest?

Red blood cell omega-3 levels take around 3–4 months to reflect a change in diet or supplements, so a retest after about 3 months shows your progress.

Do I need a referral or a nurse?

No. You can order directly, with no referral and no nurse appointment. The finger-prick takes a couple of minutes at home.
