Just been reading this research.

I can't believe why I'm reading. I take I-3-carbinol and DIM orally but hadn't thought of vaginal suppositories. I'm a scientist so found this study interesting but no idea what happened as a result of it, it was a while ago now. This product can be purchased too.
Would love if someone else can give this a read too and chat with me
