DE seemed to be more cost effective compared to charcoal. I switched from powdered zeolite to DE because I could get more DE for less. I've been taking it with Dolomite and apple cider vinegar. I've been starting out with 3 heaping tablespoons in the morning. Yes, my body is now telling me to eat beetkraut and sourkraut (the live kind), so the probiotics suggestion indicates, thank you.
