A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
In older Japanese women, higher blood DHA levels—but not EPA levels—were associated with greater gray matter brain volume.
This review summarizes evidence that omega-3 fatty acids like DHA and EPA may influence brain inflammation, protein buildup, and cognitive markers linked to Alzheimer's disease, though results across studies remain mixed.
Researchers developed advanced lab methods to identify and isolate omega-3 fatty acids from Mediterranean seaweed as a sustainable, plant-based alternative source.
Older adults with higher blood DHA+EPA levels showed larger gray matter volume and lower amyloid-beta buildup in Alzheimer's-related brain regions.
In a small trial, children with inappropriate sinus tachycardia who took omega-3 for three months showed lower heart rates and improved heart rate variability compared to untreated peers.
Genetic and clinical evidence suggests omega-3 fatty acids may modestly lower diabetic kidney disease risk and improve related markers like triglycerides and blood pressure, but not overall kidney filtering function.
High-dose omega-3s (>1500 mg/day) were linked to higher atrial fibrillation risk only in people already at high cardiovascular risk, while lower doses showed no increased risk.
Mice genetically engineered to produce more omega-3 fatty acids were protected from obesity-related spinal disc degeneration and inflammation compared to normal mice on the same high-fat diet.
Two omega-3 nutraceutical blends reduced inflammatory signaling molecules, including a sharp drop in PGE2, in human immune cells exposed to a bacterial toxin in the lab.
