I have often wondered exactly the same thing. Did

somebody test all these substances in a lab? I can only speak from my own experience. I spent many years in contact with a lot of chemicals and what did I get out? Tons of black specks. Now I'm getting the brown stuff and I was a smoker. So for me, it's working true to form. I can't say I "feel" any different but when I look at the difference in my feet, I know something's going on.

I'm going to keep going to see if the water gets clearer and if it ever does, I will definitely report back (also if it doesn't!).
