You're very welcome nanners, it's done wonders for my crohns, that's what I originally was taking it for, I had no idea it was beneficial in other ways too...I havn't even had a single mouth sore since taking it everyday...that's the key, you have to take probiotics everyday...this primadophilus is affordable, works great (is most effective compared to flora Q that I tried and acidophilus from puritans pride) and only one/day is needed, the only downfall is it must be kept in the fridge, so if you go to buy it make sure they have it stored in their frigde.
