Hey Sue, considering all acidopholus sp and other friendly spp withstand and produce acids or SCFAs i think the stomach is one of our selective mechanisms mainly against the bad guys - usually anerobes. Sure, it is very, very acidic, but some bugs do get through OK - i pointed that out once in a thread on oral sex and STD. Worth noting that salt (Na
Cl) also selects for the good guys and against the bad guys while the acid of the stomach is hydrochloric acid (H
Cl). It is one thing to say that bacteria cannot withstand a pure acid - pH of 2 - and another to say that all bacteria cannot survive in a stomach soup of fibre and chemicals where the pH is 2...
Are all probiotics sold as enteric coated?
I have more faith and appetite for some of the good bugs finding there way down the GIT rather than up it - but if it works the other way then it certainly adds value to a rectal flush - also a great use for kefir as it would avoid the dairy (casein) issue for me!

I'm personally more inclined to occasional epsom salt or sea-salt gastric flushes. May be a market there for enteric coated capsules...
