Formulation Notes

Cruciferous vegetables (cabbage, broccoli, cauliflower, etc.) are uniquely abundant in a sulfur-containing compound called Indole-3-Carbinol (I3C). In the acidic stomach environment, I3C is readily converted into DIM (diindolylmethane) plus a full spectrum of additional compounds shown to neutralize free radicals and promote proper detoxification. Studies have shown that I3C supplementation can help maintain the health of the breast and other reproductive organs.
