From the Guidelines
Probiotics supplementation can significantly improve the cure rate in adult bacterial vaginosis (BV) patients, with a risk ratio of 1.53 and 95% confidence interval of 1.19-1.97, as shown in a meta-analysis by Gou et al. 1.
Benefits of Probiotics for Vaginal Health
The use of probiotics for vaginal health has been studied in various contexts, including the treatment of bacterial vaginosis. Key findings from the existing meta-analyses include:
- A statistically significant beneficial effect of probiotics was observed in European populations and short-term follow-up days 1.
- The oral metronidazole/probiotic regimen and probiotic/estriol preparation compared with conventional antibiotics for the treatment of women of any age diagnosed with bacterial vaginosis appear promising, but well-designed randomized controlled trials with standardized methodologies and larger patient size are needed 1.
Recommended Probiotics for Vaginal Health
While the provided evidence does not specify particular strains of probiotics for vaginal health, Lactobacillus-containing probiotics are generally recommended, particularly strains like Lactobacillus crispatus, L. rhamnosus, and L. acidophilus. Products specifically formulated for vaginal health, such as RepHresh Pro-B, Jarrow Formulas Fem-Dophilus, or Garden of Life Vaginal Care, can be considered.
Usage and Precautions
When using probiotics for vaginal health, it is essential to follow the product instructions, typically taking one capsule daily for at least 1-2 months for noticeable improvement. Some probiotics can be taken orally, while others are designed for vaginal insertion. Combining probiotic use with good hygiene practices, wearing breathable cotton underwear, avoiding douches and scented products, and staying well-hydrated can help achieve the best results. If experiencing persistent vaginal symptoms, it is crucial to consult a healthcare provider before self-treating with probiotics.
From the Research
Benefits of Probiotics for Vaginal Health
- Probiotics have been shown to be effective in preventing and treating bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) 2, 3, 4, 5, 6
- The use of probiotics, particularly Lactobacillus strains, can help restore a healthy vaginal microbiota 2, 5, 6
- Probiotics can reduce the recurrence of BV and VVC, and improve symptoms and vaginal health 2, 3, 4, 5
- Orally consumed probiotics can ascend to the vaginal tract and help maintain a low pH and produce antimicrobial substances like acids and hydrogen peroxide 2
- Vaginal administration of probiotics allows for direct replacement of unhealthy vaginal microbiota and occupation of specific adhesion sites at the epithelial surface of the urinary tract 2
- The combination of probiotics and antifungals can reduce recurrence and improve symptoms of VVC 3
- Probiotics have been shown to be safe and well-tolerated, with no adverse effects reported 2, 3, 4, 5, 6
Specific Probiotic Strains and Dosages
- Lactobacillus acidophilus, Lactobacillus rhamnosus GR-1, and Lactobacillus fermentum RC-14 have been shown to be effective in preventing and treating BV and VVC 2, 4, 6
- A dose of at least 10 CFU/day for 2 months has been shown to be effective in preventing and treating BV 2
- The optimal dose, route, and duration of probiotic administration are still unclear and require further research 4, 5
