What is diindolymethane (DIM)?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Looking for a superantioxidant to help prevent cancer and other chronic diseases? Diindolymethane (DIM) may be the supplement for you. It’s both an antioxidant and phytonutrient. It can be found in a variety of vegetables, including broccoli, cabbage and brussels sprouts. However, in order to get the recommended amount of DIM, one would have to eat at least two pounds of these vegetables daily.

Some experts also recommend DIM to fight chronic inflammation in the body, especially as it ages. With inflammation, it gets harder for your body to absorb nutrients from food, to keep its immune system under control, and fight pain.

If taken appropriately, DIM is mostly safe. However, taking higher than the recommended dose can cause excess gastrointestinal distress and headaches, especially at doses of 300 mg and above. Women who are pregnant or lactating should avoid this supplement because there is insufficient safety evidence.
