Cellular and Molecular Mechanisms of 3,3'-Diindolylmethane in Gastrointestinal Cancer
International journal of molecular sciences (2016) · Systematic review
DIM acts upon several cellular and molecular processes in gastrointestinal cancer cells, including apoptosis, autophagy, invasion, cell cycle regulation, metastasis, angiogenesis, and endoplasmic reticulum (ER) stress.
Based on multiple meta-analyses showing dose-related trends for TSS improvement. 600mg/day most studied dose with significant benefit vs placebo in 73% of studies. Limited data on doses above 600mg.
Evidence primarily from preclinical studies and mechanistic research. Clinical data limited to prostate cancer studies showing detectable DIM levels. Bioavailability varies significantly by form - standard crystalline DIM has poor absorption compared to enhanced formulations. Dark urine is common but harmless.
