My favorite probiotic is EndoMune, a vegan probiotic sold on Amazon.com.
The best way to prohibit the growth of pathogenic bacteria in the birth canal is to avoid all animal products and limit the amount of toys that are used vaginally.
Wiping with baby wipes rather than dry toilet paper helps to cut down on vaginosis, as does limiting the number of sexual partners and using condoms. Having sex within 1 hour of emerging from the shower (for both partners) makes a big difference, but it may also help if a baby wipe or wash cloth is used just before sex.
I have no opinion on Refresh but I do recommend a vaginal lubricant sold under the brand name Rephresh.
Thank you for your patience on this reply. I did not see your questions for weeks! Sorry.
