Vagisan ProbioFlora Lactic Acid Bacteria contains two natural strains of lactic acid bacteria as the active ingredient: Lactobacillus gasseri , strain DSM 14869 (freeze-dried, live, at least 10 8 CFU (colony forming units)) and Lactobacillus rhamnosus , strain DSM 14870 (freeze-dried, live, at least 10 8 CFU). As soon as the lactic acid bacteria come into contact with vaginal fluid, they become active again and can develop their protective properties there.
