Krill Oil Shows Anti-Inflammatory Effects in Mouse Model of Colitis
This laboratory study examined whether Antarctic krill oil could help reduce inflammation in mice with chemically induced colitis (a model used to study inflammatory bowel disease). Researchers used a combination of advanced techniques—genetic, metabolic, and microbiome analyses—to understand how krill oil affected the animals’ gut health.
The mice given krill oil experienced less severe colitis symptoms, including less weight loss and reduced signs of inflammation, compared to untreated mice. The researchers found that krill oil appeared to calm a specific inflammatory signaling pathway (called PI3K/Akt) in the gut lining.
Additionally, krill oil supplementation was linked to shifts in the gut microbial community toward more favorable bacterial populations, along with changes in fat-related metabolites (specifically glycerolphospholipids) that are involved in cell membrane function and inflammation.
What this means for you
This early-stage animal research suggests krill oil may influence gut inflammation and microbiome balance through multiple biological pathways, but these findings come from a mouse model and have not yet been tested in humans with inflammatory bowel conditions.
