Summary
Omega-3 fatty acids may complement light-based circadian interventions by acting as non-photic zeitgebers that influence clock gene expression across neurological, metabolic, and immune pathways. For healthcare and lighting design contexts, this suggests that dietary factors could be combined with circadian lighting protocols to more robustly address circadian disruption-related conditions.
Key Findings
- Review synthesized 20 animal/human trials and 1 observational study supporting omega-3 FAs' influence on circadian clock genes across multiple physiological systems.
- Omega-3 FAs were found to regulate circadian processes in neurological, inflammatory/immune, metabolic, reproductive, cardiovascular, and biochemical domains via clock gene pathways.
- Evidence suggests therapeutic potential of omega-3 FAs for circadian disruption-related pathologies, positioning them as adjuncts to photic (light-based) zeitgebers.
