A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
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.
Severe COVID-19 patients with lower Omega-3 Index scores were more likely to need mechanical ventilation or die, even after adjusting for other risk factors.
Hospitalized COVID-19 patients with lower EPA-to-arachidonic-acid ratios tended to have more severe disease and higher inflammation markers.
In a small pilot study, hospitalized COVID-19 patients with the highest blood omega-3 levels had notably fewer deaths, though the finding narrowly missed statistical significance.
