There are vegan sources of acidophilous. I don't know how they are grown, but since lactic acid can be derived from beets as well as dairy, I suppose it's possible. "Vega"and other vegan supplements contain vegan sources of acidophilous.
Miso also contains acidophilous (or some similar good bacteria) as does tempeh. (That's why you should never boil miso or put it into boiling water: that kills the good bacteria).
I wasn't aware of the miso or tempeh. That's good info to know. I'm really worried about the vegan sources of acidophilous though. I'm wondering if they would provide enough to tame candida problems as regular acidophilous does. Right now I'm eating a ton of fruit and that's not helping the problem. Guess I'll have to try it and see how it works. Next shopping trip!
