Does bentonite remove vital minerals from your body? I am sure it does to some extent as would any mild cleanser. I don’t advocate taking bentonite for extended period of time. Bentonite does contain some aluminum and as such can cause poisoning if taken for long periods.
Same applies to good bacteria. I always take enzymes after a bowel cleanse.
Buy Bentonite in powder form instead of liquid and hydrate it yourself. It is cheaper in powder form.
