A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
A meta-analysis of 21 trials found prenatal DHA supplementation slightly increased birth weight but showed no measurable benefit for infant neurodevelopmental outcomes.
In people with type 1 diabetes, omega-3 supplementation modestly raised HDL cholesterol and lowered triglycerides but showed no effect on blood sugar markers.
In arthritic rats, mackerel-derived fish oil lowered inflammatory markers (IL-6, MMP-9) and helped preserve joint cartilage compared to untreated animals.
A lab screen found that enzymes in cholesterol, fatty acid, and eicosanoid pathways can significantly change STING-driven immune signaling.
Stroke patients with a long-term fish-rich diet and lower blood omega-6/omega-3 ratios showed better one-year functional, neurological, and mental health recovery than those with inland diets.
In a mouse sepsis model, fish oil-based IV lipid emulsion (but not soybean or olive oil) prevented a drop in intestinal blood flow and reduced liver damage.
In laying hens, fish oil and microalgae most increased yolk DHA while flaxseed oil gave the best overall omega-6 to omega-3 balance, all without affecting egg production or hen health.
In liver cells, omega-3 alpha-linolenic acid showed early fat-reducing effects while omega-6 linoleic acid triggered a delayed inflammatory response, with both fats interacting with a cholinergic (nerve-signaling) pathway linked to liver fat metabolism.
In lab-grown nerve support cells, DHA reduced the cellular stress and damage caused by excess saturated fat exposure.
