A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
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.
In rats with nerve injury, an omega-3-enriched diet reduced pain sensitivity and shifted gene activity toward better antioxidant and lipid-handling pathways.
High-dose EPA+DHA supplementation improved insulin resistance and lowered inflammatory markers in women with obesity, but most benefits faded within a month after stopping, except for insulin-related and immune gene changes which lasted longer.
In IL-10 deficient mice, omega-3 supplementation increased regulatory immune cells and reduced liver fat, but also raised markers of oxidative stress and lowered liver vitamin E levels.
In two small trials, daily krill oil supplementation was linked to reduced skin water loss and improved hydration and elasticity compared to placebo, with effects tracking omega-3 blood levels.
In mice and liver cells, omega-3 fatty acids reduced liver fat and blood lipids by lowering miR-34a, a molecule linked to fat storage genes.
