Women today live at the crossroads of multiple roles and increasing daily pressure. This fast pace often affects hormonal balance, energy levels, and—too often overlooked—women’s intimate health.
Continuing our wellness series after our article on collagen, Safic-Alcan focuses here on one of the most sensitive and crucial topics for women: vaginal microbiota balance and how to support it.
Women’s intimate comfort depends heavily on microbiota equilibrium. This delicate ecosystem is influenced by diet, stress, medication, hormones, contraceptives, hygiene habits, and even the type of underwear. When this balance is disrupted, discomfort, infections, and recurring symptoms can appear.
To better understand how to protect and maintain intimate health, we explore the main types of vaginal infections (VVC and BV), their causes, and how Quatreflora™, a patented probiotic yeast, can help support long-term vaginal microbiota balance.
Understanding the Risks of Vaginal Infections
Globally, 75% of women experience at least one episode of vulvovaginal candidiasis (VVC) or bacterial vaginosis (BV) between ages 14 and 55. These conditions account for over 10 million doctor visits per year, and 70% of vaginitis cases in premenopausal women are linked to BV or VVC.
Standard treatments such as fluconazole, metronidazole, or clindamycin remain the common medical approach. However, recurrence and antimicrobial resistance make these infections difficult to manage long term.
In fact, 56% of menopausal women present abnormal vaginal flora—highlighting how widespread dysbiosis truly is.
Vulvovaginal Candidiasis (VVC)
VVC affects women of reproductive age and is mainly caused by Candida albicans, responsible for 80–90% of cases. Candida can live harmlessly as part of normal flora, but under certain conditions (hormonal shifts, antibiotics, stress, hyperglycemia), it transitions into an invasive form producing hyphae that damage tissue.
Recurrent VVC affects 5–8% of women and is linked to multiple triggers:
- pregnancy
- contraceptives
- immunosuppression
- antibiotic or glucocorticoid use
- genetics
- intrauterine devices
Despite progress, the exact host–microbe mechanisms behind recurrence are still being explored.
Bacterial Vaginosis (BV)
BV is the most common form of vaginitis, affecting fertile, premenopausal, and pregnant women. Unlike a classic infection, BV represents a microbiota imbalance where Lactobacillus spp.—normally dominant and protective—are replaced by anaerobic bacteria such as Gardnerella vaginalis, Atopobium vaginae, or Mobiluncus spp.
Key pathogenic factors include:
- strong adhesion of Gardnerella to vaginal epithelium forming a persistent biofilm,
- destruction of protective mucus via sialidase,
- epithelial exfoliation enabling deeper spread.
This dysbiosis increases risk of recurrence, discomfort, and complications.
Why Antibiotics Are Often Insufficient
Although widely used, antibiotics present significant challenges:
- high recurrence rates (BV: up to 80%)
- resistance
- disruption of normal microbiota
- side effects
Initial cure rates for BV with metronidazole or clindamycin can be as low as 10–15% in some cases.
This is why probiotics—especially yeast-based probiotics—are increasingly recommended to maintain or restore vaginal microbiota balance.
Probiotics & Vaginal Health: A Modern Approach
Probiotics help stabilize the vaginal ecosystem by:
- promoting Lactobacillus dominance
- lowering pH through lactic acid production
- preventing harmful bacteria and fungi from proliferating
- reducing recurrence of BV and VVC
- supporting epithelial protection and immune balance
A healthy vaginal microbiota maintains a natural pH of 3.5 to 4.5, a critical barrier against pathogens.
What Is Quatreflora™?
Quatreflora™ is a patented probiotic yeast derived from Saccharomyces cerevisiae CNCM I-3856, developed to support women’s intimate health by helping restore balance to the vaginal microbiota.
Unlike bacteria-based probiotics, this yeast is uniquely resistant to antibiotics and gut conditions, making it a robust option for women experiencing recurrent disturbances.
Multiple pre-clinical and clinical studies demonstrate its effectiveness in managing and preventing intimate discomfort associated with Candida and BV-related pathogens.
Health Benefits of Quatreflora™
Quatreflora™ has several targeted benefits:
1. Helps manage vaginal infections linked to Candida albicans and Gardnerella vaginalis
It acts directly on the pathogens most commonly involved in VVC and BV.
2. Helps prevent recurrence
By supporting long-term microbiota balance, it reduces recurrence after treatment.
3. Protects the vaginal epithelium
Forms a protective barrier that limits pathogen adhesion.
4. Inhibits pathogenic virulence factors
Including hypha formation in Candida and biofilm formation in Gardnerella.
5. Supports coaggregation & displacement
It coaggregates with C. albicans and displaces G. vaginalis from epithelial surfaces.
Conclusion
Women's intimate health relies on a delicate vaginal microbiota balance. With rising recurrence of BV and VVC and limitations of antibiotic-only strategies, probiotic solutions like Quatreflora™ offer a modern, clinically supported approach to maintaining long-term comfort and microbiota stability.
