DIM, Any Thoughts on E2 and Test?


After taking 200mg a night of DIM ive cut my E2 from 55-44.

I’ve seen some posts on Reddit that say DIM can interfere with Test as well. Any thoughts on this?

DIM affects the conversion of testosterone to estrogen, if anything it’s promotes more testosterone since less is converting over to estrogen. It’s probably a very small amount though.

Good to know. It did drop my E2 11 points!


It’s difficult to know where a fluctuation ends and a decrease in estrogen due to DIM starts.

There is research showing DIM is anti-androgenic at higher dosages, but they focus on prostate cancer cells. Taking a low dosage (100-200mg) should be fine.
