probiotics...I prefer something like kefir or tibicos because they are easier to grow and have a wider spectrum of microbes......I have read someone who wrote that probiotics fed their parasites, I cant dispute that but then so does the food you eat, and in thinking on that I got to thinking of wether or not a wide variety of probiotic might also kill some parasites should they ingest the wrong ones??...sort of like using milky spore for grubs in your yard? I dont know? but it could be possible I guess?? Just a thought?
