3,3'-Diindolylmethane, commonly abbreviated as DIM, is a naturally occurring organic compound derived from the breakdown of indole-3-carbinol (I3C), which is found in cruciferous vegetables such as broccoli, Brussels sprouts, and kale. DIM is characterized by its chemical structure, consisting of two indole rings linked by a methane bridge. It is recognized for its versatile biological properties and applications.
