Just in case you thought I had anything to do with your comment being d-voted, I didn't. I almost never d-vote anything, and my comment-voting 'privileges' have been suspended due to excess u-voting. That said, I was not disputing your suggestion, but rather adding a pinch of anecdote. Saccharomyces Boulardii is one of the only 'probiotics' regularly used in clinical environments, and for good reason. Its protective effects in C-Diff alone give it credibility lacking in many prescription medicines.

No dispute here, other than for cases of compromised immunity, where pretty much everything is a potential risk.
