The star player out of this wonderful family of probiotics just has to be the RC14 strain. When it comes to women's urogenital health, there isn't much that RC-14 can't do.
It is important to understand that RC-14's role is not to "cure" you of any complaint; it's role is to follow quickly in on the heels of "the cure" so as to ensure that you STAY cured. And this it does supremely well.
Lactobacillus reuteri RC-14 is available commercially as an oral probiotic supplement mixed with another urogenital star in products such as Fem Dophilus.
If you want this specifically for a "wimmins problem", you MUST make sure it is the RC14 strain and it MUST be at a dosage of 10 billion a day. Supplements such as Fem Dophilus and Flora Restore have capsules that contain 5 billion cfu (colony forming units) so that 2 capsules give you your daily dose.
If it for general health, then any of the L reuteri strains are fine. Just be aware that if it is combined with too many other probiotics you might not be getting that much of L reuteri.
(Note that in early research L reuteri RC-14 was called L fermentum RC-14.)
