Yah, if u're having a yeast infection you could either try adding more acidophilus to your diet (like, more plain yogurt) or getting some acidophilus pills from your health food store (be sure to get the kind that is refridgerated and be sure to keep it in the fridge when u get home, too) or you could try getting some grape fruit seed extract, which is very powerful in it's yeast fighting properties.
I just finished using grapefruit seed extract to help me get rid of thrush (yeast in the breasts and in baby's mouth) and I had the liquid kind.
I got that kind because I took it in some orange juice, and also mixed some with water to put it onto my nipples to get rid of the yeast infection, and also just in case I needed to give some to my baby too. (If the "infant acidophilus" had not worked for him, I would have done a little bit of diluted grapefruit seed extract with him too, but the infant acidophilus worked so I didn't have too.)
But if you don't have to do all of that, then I would highly suggest the capsule/pill (or whatever) grapefruit seed extract, because taking the liquid internally is extremely bitter even in the juice I took it with.
But I also used to have recurrent UTI's before I got pregnant, and cranberries are more for that. I used to always take cranberry pills because I hate the taste of cranberry juice. But I think that's a little mix up in info, for I have never seen it used for the treatment of yeast infections.
