IndoleGard contains BioResponse DIM, a unique formulation containing pure diindolylmethane, an indole. Indoles are plant compounds with health promoting properties, found in cruciferous vegetables such as broccoli, cabbage, cauliflower and Brussels sprouts. Diindolylmethane, or DIM, has been shown to Enhance regulate and promote a more efficient metabolism of estrogen, by supporting the body in metabolizing estrogen into more of the protective 2-hydroxyestrone rather than the proliferative 16-hydroxyestrone. BioResponse DIM is a stable bioavailable form of DIM, made possible through a proprietary delivery system. The formula is co-solubilized with phosphatidylcholine, and microencapsulated in starch particles.
