I know but that's what the good health food store sold so I just diluted it down per the instructons on the bottle. The ionic silver I got from gnc was 10ppm and I did 2 tablespoons a day as you said. Idk because my body isn't absorbing things properly because of this illness im sure that's a factor as well. Also Grizz do you know if diatomaceous earth can help with bacteria or is that just mostly parasites and worms?
