If there's a problem with cessation of your own digestive enzymes, there's something called "Vitalzym" that replaces the enzymes your body makes on its own that are responsible for the production of other enzymes, including DE. These can be purchased.
However, I have never heard of anyone having trouble taking DE, unless they have an ulcer. And it's likely that when you're rid of the overgrowth, your digestion will return to normal. obj
