I did 1 month research before trying it, so you are doing the right thing to ask.
Search for Chlorine Dioxide, you'll find nice research articles, even in PubMed, which can assess its safety.
I've being using it for a month now. Rather than giving me problems it has done the other way, of course, besides the normal detox I understand is part of killing pathogens inside you.
It is better to read, ask, and be sure before taking any new thing. You can always come back to this forum if you make your mind.
