Clinical study: Quatreflora supports feminine health

New study discovers that Quatreflora may help to maintain the balance of vaginal microbiota

Saccharomyces cerevisiae CNCM I-3856 of Gnosis by Lesaffre, branded Quatreflora, may be effective at preventing or restoring the imbalance of the vaginal microbiota after oral administration, confirms a new randomised pilot clinical study. Results were officially presented during the “Probiota Americas 2019” in the special section of scientific posters1.

The study followed 60 healthy women of childbearing age, with regular menstrual cycles, normal vaginal flora and normal vaginal pH, having used the same efficient contraception method for at least three months.

The migration of the probiotic, from intestine to vagina, has been proven after a daily four-week oral supplementation: 21% of women who took 500 mg of yeast probiotic presented migration of the Lesaffre’s probiotic strain in the vagina microbiota.

This proportion is comparable to what has been observed with lactobacilli probiotics, especially in one study where the probiotic was revealed in the vaginal microbiota of five out of 20 women (25%) after a four-week supplementation2.

Quatreflora showed a pronounced ability to survive all along the gastrointestinal tract. “As far as we know, the migration of a probiotic yeast from rectum to vagina has never been described before our pilot clinical study,” said Silvia Pisoni Marketing Manager of the company. “Probiotics are very promising candidates in preventing or restoring the imbalance of the vaginal microbiota. According to the findings of the trial we really believe Quatreflora may contribute to the delicate women health”.
