  • SUPPORTS HEALTHY ESTROGEN AND HORMONE LEVELS: Indole-3-Carbinol, a precursor to DIM, helps to metabolize excess estrogen, regulates estrogen production, and helps to maintain a healthy hormone balance in both men and women. In addition, Indole-3-Carbinol promotes liver detoxification, provides antioxidant and cellular support, aids in overall bodily detoxification, promotes better fat burning, and may help to prevent or improve a number of auto-immune diseases.
