Supporting long-term microbiome balance with probiotic add-back therapy
Antibiotic therapy, even when effective at clearing an active infection, does not restore the healthy vaginal flora that keeps harmful bacteria in check. Without deliberate repopulation, the ecological vacuum left behind creates the ideal conditions for recurrence. Probiotic add-back therapy addresses this gap directly.
Lactobacillus species, particularly L. crispatus and L. rhamnosus, are the dominant organisms in a healthy vaginal microbiome. They produce lactic acid and hydrogen peroxide, which lower vaginal pH and create an environment that is inhospitable to the polymicrobial organisms responsible for BV. Supplementing with clinically validated strains after antibiotic treatment helps re-establish this protective barrier and significantly reduces the likelihood of recurrence.
Products such as Metagenics UltraFlora Women's are formulated with clinically studied Lactobacillus strains specifically selected to support vaginal and urogenital health. When used as part of a structured add-back protocol following treatment, they help sustain the microbiome balance that prevents biofilm reformation and recurrent infection over the long term.
