Evidence Summary
DIM (diindolylmethane) is a compound studied for its ability to modulate estrogen metabolism and hormone biomarkers. Research primarily focuses on its potential role in breast and prostate cancer contexts and its impact on metabolic health.
Evidence by Condition
Studies have investigated DIM's effect on hormone metabolites and biomarkers in patients with a history of breast cancer or those taking tamoxifen.
A Phase Ib trial explored DIM's impact on tissue biomarkers in patients undergoing prostatectomy.
Research suggests DIM may favor benign estrogen metabolism and assist in decreasing body fat in premenopausal women.
Effective Doses
Dose ranges not specified in the provided research.
Key Findings
- DIM supplements may favor benign estrogen metabolism and decrease body fat in premenopausal women (PMID: 36111381)
- DIM has been studied for its ability to modulate breast cancer biomarkers in patients taking tamoxifen (PMID: 28560655)
- DIM was investigated for its effect on tissue biomarkers in prostate cancer patients (PMID: 26313229)
Limitations
The available research is limited by very small sample sizes (e.g., N=2) and a primary focus on tissue biomarkers rather than long-term clinical outcomes.

Frequently Asked Questions
What is DIM and how does it work?
DIM (diindolylmethane) is a compound studied for its ability to modulate hormone biomarkers and estrogen metabolism. There is moderate evidence suggesting it may help promote more benign estrogen metabolism.
Can DIM help with body fat loss?
There is moderate evidence suggesting that DIM may assist in decreasing body fat in premenopausal women. However, more research is needed to confirm its effectiveness for broader weight management.
Does DIM help with breast cancer?
There is currently insufficient evidence to conclude that DIM helps with breast cancer. Research has focused on its effect on hormone biomarkers in patients already taking tamoxifen, but results are not conclusive.
Is DIM effective for prostate cancer?
There is insufficient evidence regarding DIM's impact on prostate cancer. While a small trial investigated its effect on tissue biomarkers in patients undergoing prostatectomy, more study is required.
What is the recommended dose of DIM?
The provided research does not specify an effective or recommended dose range for DIM. You should consult a healthcare professional for personalized dosing advice.
Is DIM safe to take and are there any side effects?
There is no specific safety or interaction data provided in the current research. Because the safety profile is not fully documented, you should speak with a doctor before starting this supplement.
Are there any known drug interactions with DIM?
There are currently no documented drug interactions for DIM. However, you should always consult your physician to ensure it will not interfere with any medications you are currently taking.
