A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
Combining gene-marking, gene-activity, and genetic data suggests omega-3 fatty acids may influence aging-related biology partly through changes in gut bacteria and gene regulation.
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.
In adults with prediabetes, combining omega-3 fatty acids with plant sterols for 12 weeks improved triglycerides, fasting blood sugar, insulin resistance, and HbA1c more than placebo.
In diabetic patients, omega-3 supplementation was linked to lower triglycerides and reduced Apo AII levels compared to controls.
This review found that omega-3 fatty acids are consistently linked to improvements in liver fat, triglycerides, and some liver enzymes in MAFLD research, while newer bioactive fats like furan fatty acids and FAHFAs show early but inconsistent findings.
A newly launched Brazilian trial will test whether adding phytosterols and/or krill oil to a heart-healthy diet improves cholesterol markers in people with familial hypercholesterolaemia, with results expected by mid-2026.
