A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
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.
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.
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.
In hemodialysis patients, lower hemoglobin was linked to distinct red blood cell fatty acid patterns and rising ZnPP, a marker of iron-limited red blood cell production.
A 4-month vegan multinutrient supplement significantly raised omega-3 index and vitamin D levels compared to placebo, with no extra benefit from doubling the dose.
