Thank you for posting an answer, as I see noone else did. I bought this a few days ago, but haven't opened it yet. I wanted to read the dosage info before opening, and stumbled across this statement. So i'm on a mission to investigate it as well, hense, I am here. I downloaded the Prop 65 list of cancer causing chemicals, but without a chemical name, it really was useless; so was about to go to the website, and found your post, asking the same questions that are dancing around in my mind. Thank you again for providing an answer. I would still like to know more, as I might take it back and find an organic alternative.
