Oh yeah, forgot to mention.....cipro wipes out the good flora within your GI tract. I suggest one with a high count of broad strains - like start at 10 billion and work up from there. This is to repopulate what the cipro wiped out and if good bacteria doesn't repopulate that GI territory, opportunistic candida will take that space over which makes things more difficult to correct. There's lot's of good information about probiotics in the link in my prior response at thecandidadiet.com/forum .......
