Butyrate is a short-chain fatty acid produced in the gut when dietary fiber is fermented by beneficial bacteria. It plays a crucial role in maintaining gut health by providing energy to colon cells and supporting the integrity of the intestinal barrier. Additionally, butyrate has anti-inflammatory properties and may help regulate immune responses. It is also linked to various health benefits, including improved digestion and potential protective effects against certain diseases, such as inflammatory bowel disease and colon cancer.
