Abstract

ALM@AG significantly reduced inflammation and improved gut health in a model of colitis.

  • Astaxanthin (AXT) is an antioxidant that may help treat inflammatory bowel disease (IBD) and associated psychiatric disorders.
  • ALM@AG enhances the bioavailability and targeted delivery of AXT to colon lesions.
  • The system demonstrated effectiveness in reducing inflammation and modulating gut microbiota.
  • ALM@AG helped repair the intestinal barrier and restore metabolic balance.
  • Treatment with ALM@AG alleviated depression-like behaviors linked to colitis by regulating neurotransmitters and reducing brain inflammation.
  • Interactions among genes, microbiota, and metabolites were explored in the context of IBD and psychiatric disorders.
