Hi PinkGilly,
The product I am taking is Indolplex. I buy it from the Health Food Store. My Naturopth put me on it. It contains Diindolylmethane. From what I understand t comes from the same source - cruciferous vegetables. It may be a different product to 3 Carbinol. I have been taking it with Tamoxifen, although I soon will be going off that as I am having a complete hysterecomy and apparently the medication will change. I am considering not taking anything other that Indolplex. My understanding is that Indolplex assists in healthy metabolism of estrogen. Sorry I cannot help you anymore. My oncologist wasn't interested in learning more about Indolplex, even though I had some research papers supporting it. Good luck with your research and have a beautiful day!
