Tony, any idea where I can find more info?

Tony! Thanks for the useful comments!

I'll go google anaerobic bacteria as related to constipation, to see what I can find out about that. I'd always suspected my problem may be a bacterial imbalance rather than just candida, but I'm not sure about the aerobic versus anaerobic part for me.

The Oxygen-based Colon Cleanse products that introduce oxygen into the gut actually slow down my gut even more, so I don't know what that means for me. (die-off? Or actually making an imbalance worse for me and thus aggravating slow elimination? who knows).

Do you happen to know where I can find more info about the pH of various acids - you quoted citric acid 's pH, and I'm wondering what the pH of vitamin C powder is...
