A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
In pregnant women, lifestyle factors like smoking, alcohol use, and pre-pregnancy weight were linked to differences in red blood cell fatty acid patterns and oxidative stress markers.
In rats, paternal DHA supplementation before conception did not prevent diet-induced obesity or liver fat problems in offspring, but it influenced fat-metabolism gene activity in a sex-specific way.
Herring roe phospholipids boosted production of pro-resolving lipid mediators in immune and skin cell lab models, suggesting a possible mechanism behind their observed skin benefits.
In lab-grown immune and skin cells, herring roe oil reduced IL-23/IL-17 inflammatory signaling linked to psoriasis pathways.
High-dose purified EPA showed cardiovascular benefit in some high-risk diabetes populations, while low-dose EPA+DHA combinations generally did not, and omega-6 evidence remains too limited to draw firm conclusions.
Adding 3g/day of EPA+DHA to a heart-healthy diet significantly improved a ceramide-based cardiovascular risk score (CERT2) compared to diet alone.
Researchers are calling for stronger, more consistent scientific standards to measure and confirm the real biological effects of oxylipin signaling molecules.
People with a genetic tendency toward lower baseline omega-3 levels showed a bigger rise in blood omega-3s after fish oil supplementation than those genetically predisposed to higher levels.
In rats, an omega-3-enriched maternal diet during pregnancy and lactation improved offspring brain fat composition and partly reversed metabolic problems caused by a high-fat diet, with effects differing by sex.
