Vaginal Probiotics?

I work at Whole Foods and it's "Team Member Appreciation Week". We got fun little gift bags and a lot of them contained vaginal probiotics (which you take orally and can imagine the conversation when we found that out.)

Now, on a regular basis I a prenatal, fish oil, a regular probiotic, magnesium and biotin (on the suggestion of people with great skin). I'm definitely not against vitamins and supplements. Is anyone taking vaginal probiotics? Any thoughts?
