DIM

Also known as: Diindolylmethane, 3,3'-Diindolylmethane

A compound derived from the digestion of indole-3-carbinol, found naturally in cruciferous vegetables such as broccoli and cabbage. Used to support oestrogen metabolism, particularly to promote conversion to less potent oestrogen metabolites. Popular for PMS, hormonal acne, and oestrogen dominance.

Research Context

Research context compiled from published sources

How does DIM work?

Modulates oestrogen metabolism by promoting the 2-hydroxylation pathway (producing less active 2-hydroxyoestrone) rather than the 16α-hydroxylation pathway. Also influences CYP1A2 enzyme activity and may have anti-oestrogenic effects in oestrogen-dominant tissues. Some evidence for anti-proliferative effects in cell studies.
