I had/have a urinary infection and Cipro was prescribed. Being vegan, I don't want to eat yogurt to replace the gut flora. What would a vegan replacement be?
Silk and WholeSoy both make a vegan yogurt with live cultures. Both are pretty good. If you don't have a local source, you can buy probiotic liquids from a health food store (I haven't tried those, so I can't vouch for the taste).
