Cranberry and D-mannose can help in the moment but don't change the underlying flora. OTC yeast treatments handle a flare-up and stop there. General probiotics from the drugstore have two problems: most of the strains die in stomach acid before reaching where they need to go, and even the ones that survive aren't specifically formulated for women's health.
Antibiotics solve one problem and often create another, by disrupting the very flora that was keeping you balanced.
Doctor's Biome was built to be the daily foundation underneath all of that. Living, liquid probiotics formulated specifically for women, in a juice that keeps them alive through the trip.
