Cover Story: The Omega-3 Index (O3I) reflects the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content in erythrocytes and is associated with numerous health outcomes. We investigated whether urinary metabolites could be used to non-invasively monitor the O3I in a secondary analysis of a randomized clinical trial in males and females who consumed either ~3 g/d olive oil (control), EPA, or DHA for 12 weeks. Fasted blood and first-void urine samples were collected at baseline and following supplementation. Urinary S-Carboxypropylcysteamine and an unknown dianion were identified as biomarkers of the O3I. This research represents an important advancement in the search for accurate, unbiased, and non-invasive biomarkers of omega-3 status, and could have great potential to advance precision nutrition strategies to improve individual health.
