Thanks, Albalover. I used Andy Cutler's protocol with DMSA a few years ago after I removed my mercury fillings and crowns. I stopped when I realized that I had a bit of Amalgam under the skin in my gum. I wasn't sure I should continue as you're not supposed to chelate with mercury fillings. Maybe that little bit is not enough to worry about, I don't know.
Seems I remember Cutler suggesting to chelate shortly after removal of Amalgams before the body sequesters mercury into the cells, though. It's been 4yrs since mine were removed.
I was hoping to find something a bit gentler and DE looked to be good for the intestines and colon.
