Ingredients

5 Probiotic Strains:

L. plantarum ROSELLA: improves pH, reduces itching and discharge, and lowers vulvovaginal candidiasis recurrence for up to six months, with no reported side effects.

L. rhamnosus Rosell^®-11 & B. bifidum HA-132: supports vaginal and immune health, especially during hormonal changes like pregnancy. L. rhamnosus produces lactic acid and hydrogen peroxide to suppress pathogens and maintain acidic vaginal pH, while B. bifidum supports epithelial integrity and modulates inflammation.

L. crispatus Rosell^®-470 & L. gasseri HA-275: help restore and strengthen the vaginal microbiome’s natural defenses, especially after antibiotics or during hormonal shifts such as menstruation, pregnancy, or menopause.
