Ok, I showered and dressed for work, but I did find where I read about DIM. It was a post in a hair loss forum. So it is not really an article from any medical testing just a reference to some information. I may do some digging later after work if I have time. So here is the reference and a link to the forum. Note some of the conversation on this forum is not from experts. Just saying.

" As a side note, for a long time DIM extracts were poorly absorbed by the body. Supposedly, a guy named Dr. Zeligs developed a formula that had better bioavailability and he has patented the technology to numerous supplement makers, including Nature's Way."
