Indole-3-carbinol is one of the major anticancer substances found in cruciferous (cabbage family) vegetables. It is a member of the class of sulphur-containing chemicals called glucosinolates.1 It is formed from parent compounds whenever cruciferous vegetables are crushed or cooked.2 3 Where is it found?Indole-3-carbinol is found in highest concentrations in broccoli, but is also found in other cruciferous vegetables, such as cauliflower, cabbage, and kale. Indole-3-carbinol has been used in connection with the following conditions (refer to the individual health concern for complete information):
Who is likely to be deficient?As indole-3-carbinol is not an essential nutrient, no deficiency state exists. How much is usually taken?Based upon preliminary studies it is estimated that the minimum amount required for the prevention of breast cancer is 300 to 400 mg daily.4 Are there any side effects or interactions?No side effects from indole-3-carbinol have been reported.
