The microbial metabolite, Urolithin A, derived from a compound found in berries and pomegranates, can reduce and protect against inflammatory bowel disease (IBD). Urolithin A (UroA) and its synthetic counterpart, UAS03, mitigate IBD by increasing proteins that tighten epithelial cell junctions in the gut and reducing gut inflammation in animal models. Tight junctions in the gut barrier prevent inappropriate microorganisms and toxins from leaking out, causing inflammation characteristic of IBD.
