Diindolylmethane is produced in the body after cruciferous vegetables are eaten. Specifically, it is produced by the breakdown of glucobrassicin in the vegetables. Cruciferous vegetables include broccoli, cauliflower, Brussels sprouts and cabbage.


Diindolylmethane, also called DIM, is a phytochemical obtained from plants. Phytochemicals are biologically active, but not nutritive. DIM is classified by the FDA as a dietary supplement and is not treated as a drug; therefore, it is not as well regulated.

Side Effects

No side effects of diindolylmethane have been reported, but this does not mean that no side effects exist or are possible. When taken as a supplement, always contact your doctor or pharmacist before taking it with other medications. Little is known about any drug interactions with diindolylmethane.


Even though diindolylmethane is natural, this does not mean it is totally free of side effects, or even safe to use as a medication. Before taking a supplement, always check with your doctor if you have any medical problems or conditions such as cancer, cirrhosis, liver or kidney disorders.

Treatment and Claims

Diindolylmethane is used to treat oestrogen metabolism, human papilloma virus and PMS. It is also used to treat various types of cancer, including breast cancer, uterine cancer and colon cancer, and as an immune system enhancer. Further research is needed to verify the validity of any claims or even if diindolylmethane is effective in these treatments.


This information is not intended to replace medical advice. Always check with your doctor if you are taking other medications and before you start taking diindolylmethane supplements. Report any suspected side effects to your doctor.
