Honestly, I don&#x27;t think probiotic yogurt really contains as much of the bacteria as you would need to affect your system. I bought two 4-packs of that stuff and ate them over the course of a week as a replacement for the over the counter stuff, just to see if it would help. No effect whatsoever. Went back to the over the counter stuff (Udo&#x27;s Choice, which is expensive, refrigerated stuff from Whole Foods) and I was right again. Though I have to say, probiotic with 102 billion cells might be pushing it for most. Flora-wise, I felt like I had a whole rainforest coming out of my ass, but it wasn&#x27;t really a bad experience. It fixed my burning diarrhea after my run of antibiotics.
