V-Spot combines four clinically-researched vaginal probiotic strains designed to restore healthy vaginal and urinary tract microbiomes through targeted mechanisms that address bacterial imbalances, infections, and inflammatory conditions affecting intimate health.

Lactobacillus crispatus is a dominant strain in healthy vaginal microbiomes, producing lactic acid that maintains optimal acidic pH levels and creates an environment hostile to pathogenic bacteria and yeast. This strain forms a protective biofilm on vaginal epithelial cells, preventing harmful microorganisms from adhering and establishing infections while supporting the natural self-cleaning mechanisms of the vaginal tract.

Lactobacillus rhamnosus (GR-1) and Lactobacillus reuteri (RC-14) work synergistically to support vaginal and urinary tract health through potent antimicrobial, anti-adhesion, biofilm-modulating, and pH-regulating mechanisms. L. rhamnosus GR-1 restores a Lactobacillus-dominant microbiome by colonising the vaginal tract after oral intake and producing lactic acid and hydrogen peroxide, which lower vaginal pH and inhibit pathogens including E. coli, Gardnerella vaginalis, and Candida albicans [14][15][17][21]. Clinically, GR-1 suppresses Candida growth by 52-73%, blocks fungal metabolism and biofilm formation, improves bacterial vaginosis (BV) culture results in 59% of women, and when paired with antimicrobial treatment normalises BV markers in 88% versus 40% with placebo [14][15][17][21].

L. reuteri RC-14 works synergistically with GR-1, adhering to the vaginal epithelium and producing lactic acid, hydrogen peroxide, and bacteriocins that inhibit E. coli, Candida albicans, and BV-related anaerobes while preventing pathogenic attachment. In recurrent UTI populations, daily GR-1 + RC-14 lowers infection frequency from 6.8 to 3.3 UTIs per year. Clinical trials consistently show that GR-1 + RC-14 increases vaginal Lactobacillus counts, normalises microbiome swabs in 90% of women, and restores healthy flora in 61.2% versus 26.85% using placebo [14][15][17][21].

Lactobacillus gasseri is naturally found in healthy vaginal microbiomes and contributes to maintaining optimal vaginal pH while producing antimicrobial compounds that help prevent overgrowth of harmful bacteria and yeast. This strain supports the overall balance of the vaginal ecosystem and works complementarily with the other strains to provide comprehensive intimate health support.
