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.
