I don't recall reading anything about I3C supplementation in the AED book, but I thought these were interesting reads:
http://www.thorne.com/media/Indole_mono10-4.pdfhttp://www.nowfoods.com/?action=itemdetail&item_id=41666i found this stuff for very cheap ($12 for 60 caps, full dose is 2 caps/day), which I thought was a great deal compared to some of the other anti-estrogenic supplements that are available.
Anyone have experience with this product or opinions?
