Pharmaceutical grade probiotics DON’T attach the intestinal lining permanently. There isn’t prove of it. They do temporary colonization until you be supplementing them. If you stop, it is matter of time ( weeks or months ) that there isn’t detectable amount of those strains in feces and biopsies. Moreover, the dominant colon microbiota is anaerobic, a thing that difficult the pharmaceutical productions. Lactobacillus and Bifidobacterium aren’t included as the main fenotypes that populate the human colon. There are other species that dominate.
So, with S. Boulardii or without it, your colon will be populated with species coming from the environment, food, and native species. You can not hope to gain colonies that come from pharmaceutical pills because science hasn’t proved it. Don’t get me wrong. Colonization is possible as long as you supplement, but if you stop, they don’t last. The same thing happens with S. Boulardii, you need to keep supplementation to allow a temporary colonization. They are all transients. L. Reuteri, L. Plantarum ( V-299 ) and some L. Acidophilus strains have colonized longer than other known species but they don’t attach permanently either.
