Activia or DanActive for C Diff
I’ve been asked whether Activia is good to take for curing C Diff. Let me start with the disclaimer: I’m not a physician. You should consult a qualified physician to diagnose and/or treat C Diff or its symptoms.
No Evidence (yet) that Activia cures C Diff
Now, with that said, I looked at Danon’s site and found that the “active” ingredient in Activia is “Bifidobacterium animalis lactis”. So far, I’ve found no evidence or studies that show that Activia is effective in combatting C Diff. I wouldn’t say that it is useless to eat Activia as it appears to have other intestinal benefits, but I just haven’t personally found evidence that it combats C Diff.
DanActive On The Other Hand
However, I did find one study that suggests that DanActive may be associated with a lower rates of getting C Diff in the first place.  This study showed that drinking Danon’s mixture of Lactobacillus casei, L bulgaricus, and Streptococcus thermophilus may reduce the likelihood of getting C Diff. The study sites 0% of the DanActive drinkers came down with C Diff versus 17% of the non-DanActive drinkers. The study is published by Dannon, but I’ll give it a try.
