The present open-label, single-arm, prospective interventional study was designed to evaluate the safety and therapeutic efficacy of an oral probiotic formulation (MetSheFloraProTM – Slow-Release Capsule) in women diagnosed with mild to moderate bacterial vaginosis (BV). In addition to addressing the clinical symptoms of BV, this study aims to explore the potential benefits of MetSheFloraPro™ in promoting overall vaginal health, thereby improving sexual health and well-being in women. By restoring a healthy balance of vaginal microbiota, the probiotic formulation help reduce discomfort, odor, and irritation commonly associated with BV, potentially enhancing sexual satisfaction and confidence. Furthermore, maintaining a balanced vaginal flora is essential for preventing recurrent infections and supporting optimal reproductive health. This could significantly improve the quality of life and sexual health outcomes for women dealing with BV. The study was prospectively registered with the Clinical Trials Registry of India (CTRI/2024/05/067530) and ClinicalTrials.gov (NCT06486103) and enrolled adult female subjects who satisfied the predefined inclusion and exclusion criteria.
Following a structured screening process, eligible subjects underwent baseline clinical and laboratory assessments and subsequently received the investigational product for a duration of 30 days. Subjects administered one probiotic capsule twice daily, and strict adherence to storage and handling requirements. Efficacy assessments included evaluation of vaginal discharge characteristics, odor, itching, Nugent scoring, and vaginal pH, complemented by treatment perception data captured using a structured questionnaire. Safety evaluations were conducted by gynecological examination, clinical symptom monitoring, and laboratory investigations.
Subjects exhibited relief from vaginal odor and itching, improvement in discharge quality, and stabilization of vaginal pH. Nugent scoring indicated a favorable shift toward restoration of a healthy vaginal microbiota. Subjects-reported outcomes revealed high levels of acceptability, reporting positive perceptions regarding capsule palatability, aftertaste, gastrointestinal tolerance, and overall confidence in its contribution to vaginal health. The investigational product was well tolerated, with no treatment-related adverse events or clinically significant alterations in laboratory safety parameters observed.
MetSheFloraProTM, a multi-strain probiotic formulation comprising Lactobacillus and Bifidobacterium species, demonstrated a favorable safety profile and clinically relevant efficacy in improving vaginal health among subjects with mild to moderate BV. The findings support its role as a safe and effective adjunctive strategy for restoring vaginal microbial balance and alleviating BV-associated symptoms.
Results
Percentage change in Quality of Vaginal Discharge
At baseline before usage of the test treatment, 75% subjects having white discharge, 25% subjects having clear and stretchy discharge. Post 15 days usage of the test treatment, 100% subjects having clear and stretchy discharge. Continues 30 days usage of the test treatment shows 16.67% subjects having white discharge while 83.33% subjects having clear and watery discharge.
Change in Nugent score
At baseline (Day 01), prior to the administration of the test treatment 100% exhibited a Nugent score ranging between 7 and 10, indicating the presence of bacterial vaginosis (BV). Following 30 days of test treatment administration, 58.33% subjects demonstrated a Nugent score of 0–3, indicative of a normal vaginal microbiota. Additionally, 33.33% subjects exhibited an intermediate bacterial count with a Nugent score of 4–6, while 1 subject 8.33% continued to have a Nugent score of 7–10, suggesting the persistence of BV.
These findings indicate a notable reduction in bacterial vaginosis, with a shift toward a healthier vaginal microbiota in the majority of participants, thereby supporting the potential efficacy of the test treatment in restoring vaginal microbial balance.
At baseline (Day 01), prior to the administration of the test treatment, 83.33% subjects exhibited a vaginal pH ranging between 1 and 6, indicating a very acidic to slightly acidic environment, while 16.67% subjects had a neutral vaginal pH. Following 15 days and 30 days of test treatment administration, 100% demonstrated a vaginal pH within the range of 1 to 6, signifying the maintenance or restoration of an optimal acidic vaginal environment. These findings suggest that the test treatment may contributed to sustaining vaginal acidity, which is essential for maintaining a balanced vaginal microbiota and inhibiting the overgrowth of pathogenic bacteria associated with bacterial vaginosis.
Change in VAS score for vaginal itching
At baseline, before usage of the test treatment all the 100% subjects having presence of vaginal itching, while post 30 days usage of the test product all 100% subjects having no itchiness observed.
Change in VAS score for odour of vaginal discharge
At baseline, before usage of the test treatment all the 100% subjects having presence of vaginal odour, while post 30 days usage of the test product all 100% subjects having no odour.
After 30 days of consuming the test treatment, consumer perception questionnaire assessments indicated the following results:
100% subjects liked the fragrance of the oral probiotic capsule MetSheFloraProTM.
100% subjects liked the taste of the oral probiotic capsules MetSheFloraProTM, found palatable.
100% subjects felt the pleasant after taste of the oral probiotic capsule MetSheFloraProTM.
100% subjects relieved from the gastrointestinal discomfort (abdominal pain, bloating, changes in bowel habits, nausea, vomiting, and indigestion) after taking oral probiotic capsule MetSheFloraProTM.
100% subjects liked the overall palatability of the oral probiotic capsule MetSheFloraProTM.
100% subjects were confident in terms of improving the vaginal health MetSheFloraProTM.
100% subjects perceived better overall health post dose of the oral probiotic capsule MetSheFloraProTM.
100% subjects agreed to recommend the oral probiotic capsules MetSheFloraProTM to family or friend for improving the vaginal health.
