QuatrefloraTM new clinical validation available: ask for the SCIENCE UP

QuatrefloraTM is a patented and proprietary strain Saccharomyces cerevisiae CNCM I-3856 with widely described mechanisms of actions and 6 scientific publications in peer-review journal about its efficacy in maintaining proper vaginal balance.


This randomized, double-blind, placebo-controlled clinical study was performed to evaluate the recovery of S. cerevisiae CNCM I-3856 in vaginal samples in healthy women after oral consumption.


Oral consumption of the yeast probiotic S. cerevisiae CNCM I-3856 for vaginal health rather than local administration may be:


  • An easier and more convenient way of administration, allowing a better compliance.
  • Effective to exert an antipathogenic action in the intestine which is known to be a potential source of vaginal infection.
  • A more handful, practical and market-oriented way for women to potentially better manage their urogenital health.


Vaginal balance is fragile and many internal or external factors can affect this balance, this will increase the risk of intimate health problems.


Thanks to its beneficial actions upon the gut and vaginal microbiota, QuatrefloraTM,  patented and proprietary strain Saccharomyces cerevisiae CNCM I-3856,  can help healthy vaginal flora.
