(I would not recomend purchasing them online since the temperature will undoubtedly be compromised at some point in the mailing process. Also dont get the ones on the unrefridgerated shelf. You need to use refrigerated probiotics.
Jarrow formulas is a good (I open the capsule into my mouth to avoid the gelitan capsule, It tastes good.)brand.http://www.jarrow.com/category.php?catid=25&PHPSESSID=415e08138fb6d48cee8e5343e3603578 Nondairy types are best as well.
I also use pro-96 blueberry or apple http://www.natlife.com/PPS/Pro96AcidoPPS.htm
They taste great and even kids have no problem taking it. Im treating my 4 year old for a vaginal infection right now actually and she had relief the next morning. Its good to take a maintenance dose esp if you are prone to yeast.
Probiotics have so many other health benefits as well. They are outlined in the links I listed.
A wonderful discussion, with ideas on how, why and what type of probiotics to use.

If you use store bought yogurt make sure it is sugar free. Otherwise you are feeding the yeast and it will be a battle for your body to get the benefits.
Also lots of water.
Good Luck!
