Journal of the science of food and agriculture (2012) · Meta analysis · n=26
Compared with the placebo groups, serum TC and TG levels in the garlic group were reduced by 0.28 (95% CI, -0.45, -0.11) mmol L⁻¹ (P = 0.001) and 0.13 (95% CI, -0.20, -0.06) mmol L⁻¹ (P < 0.001), respectively.
Indole-3-Carbinol: Occurrence, Health-Beneficial Properties, and Cellular/Molecular Mechanisms

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.
Meta-analysis shows modest SBP reduction of ~4 mmHg and DBP reduction of ~1.4 mmHg. Effect size is relatively small compared to pharmaceutical interventions. Studies primarily used aged garlic extract forms.
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.
AI-estimated from published studies. Interpret as directional guidance.
Aged Garlic Extract has a higher evidence score (9/10 vs 8.5/10) and wins in 3 of 3 categories.
