Butyric acid is a short chain fatty acid that contains 6 carbon atoms. It is found naturally in the digestive tract and its use in pathologies with intestinal involvement. It is the main energy substrate of the enterocyte and stimulates the absorption of sodium and water in the colon and presents trophic action in the intestinal cells. Its properties and the role it plays in the gastrointestinal tract have been known since ancient times; however, recent research shows that it remains a molecule with great potential.
