Comparing Fish Oil and Krill Oil: Effects on Liver and Brain Fats in Mice
In mice, fish oil and krill oil both raised omega-3 levels but altered different liver and brain fat classes linked to inflammation pathways.
A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
In mice, fish oil and krill oil both raised omega-3 levels but altered different liver and brain fat classes linked to inflammation pathways.
In mice on a high-fat diet, long-term krill oil supplementation raised anti-inflammatory omega-3 compounds and reduced inflammation markers in fat tissue and liver.
In rats fed a high-fat diet, krill oil supplementation was linked to improved liver cell energy metabolism, including better fat-burning and mitochondrial function.
In mice on a high-fat diet, krill oil showed somewhat stronger effects than other omega-3 forms on liver fat, enzymes, and LDL cholesterol, linked to changes in the CB1/adiponectin/ceramide pathway.
Lipase-treated krill oil, but not fish oil, significantly increased brain DHA and EPA levels in mice.
In rats on a high-fat diet, krill oil and fish oil both modestly affected lipid levels but showed limited and differing effects on obesity-related markers and fat-metabolism genes.
