Why people use it
It is marketed for estrogen metabolism, hormone balance and detox support.
These are common goals and marketing uses. The evidence section below explains what research supports.
What does the evidence tell us?
Small studies show changes in estrogen metabolites, but this does not establish improved hormone balance or health outcomes. Detox claims lack supporting clinical evidence.
What should I know before using it?
Avoid during pregnancy, while trying to conceive or while breastfeeding. Seek advice with hormonal contraception, tamoxifen or other medicines because DIM can alter their effects. Do not self-treat hormone symptoms.
