A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
In obese mice, Antarctic krill oil reduced diet-induced high cholesterol, liver fat buildup, and oxidative stress by influencing key cholesterol-regulating pathways.
In obese mice, krill oil (but not standard fish oil) reduced liver fat buildup by over 40% and improved markers of liver stress and insulin sensitivity.
In diabetic mice, krill oil reduced liver damage markers and ferroptosis-related oxidative stress while boosting the liver's natural antioxidant NRF2 pathway.
In mice, krill oil pretreatment reduced toxin-induced liver damage, oxidative stress, and inflammatory signaling more effectively than fish oil.
In diabetic rats, fish oil, krill oil, and combined EPA+DHA (from algae or ethyl esters) similarly improved nerve and blood vessel function, while DHA alone was nearly as effective and EPA alone was the weakest.
In mice, fish oil and krill oil both raised omega-3 levels but altered different liver and brain fat classes linked to inflammation pathways.
