A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
In mice and human blood samples, low EPA levels were linked to worse heart-filling problems, and high-dose EPA improved heart function in mice through a TREM2-dependent cell-clearing pathway.
This narrative review suggests omega-3 fatty acids may help regulate pathways linked to age-related protein damage (AGEs) and related inflammation, though more direct clinical trials in older adults are needed.
People with higher blood DHA (omega-3) levels had lower rates of testing positive for and being hospitalized with COVID-19 in a large UK population study.
A review of 18 studies found lower omega-3 levels were often linked to more severe COVID-19 and higher mortality, though findings on high fatty acid levels in critical illness were mixed.
In a meta-analysis of six trials, omega-3 fatty acid supplementation was linked to lower overall mortality in hospitalized COVID-19 patients, though evidence certainty was low.
This review compiles clinical research suggesting omega-3 fatty acids may support anti-inflammatory processes in neurodegenerative diseases, while omega-6 fats show more mixed effects.
