Some of the spore-based probiotic strains, like bacillus subtilis, have been used in most of the world (in Europe, Asia, and Latin America) as prescription drugs since 1952 and have thousands of studies on them. Only a few of the bacteria in the soil are bacillus species and have endospores and these are the ones that can survive the trip down our digestive tract and are native to our gut.ĩ:35 If you do a Google search for spore-based probiotics, mostly negative articles come up that claim that they are new and that there are very few studies on them. This is why most other, non-spore-based probiotics are killed by the time they end up in the colon.Ħ:59 The difference between soil based and spore-based probiotics is that most of the bacteria in the soil have no benefit for us in our gut as probiotics.


Because these probiotics are encased in a spore, they have the capability to survive through the acid in the stomach and the bile salts and the pancreatic enzymes in the small intestine. Ben Weitz.ĥ:49 When Kiran was researching which strains of probiotics are most effective and have the most research, he kept coming back to the spore-based bacillus species.
