The Malic Acid is to soften gall/ liver stones so they are softer and less likely to hurt you coming out (squish out easier, too). I am curious, only because I have tried both PB shakes and Homozon (Mag/oxide), but never together. I was thinking about doing it, but I wasn't sure if that was colon overload. How quickly did you see results? never had a rope, and it's kind of disheartning (if you can believe it) that I have only had soft stoods with the Homozon. I want to up the doseage, but if you've had success with the PB and Mag Oxide, I may try the same, you know, just for fun. lol.
