Multi-Gyn Actigel is the only one of the four tested vaginal gels that does not quickly destroy the lactobacilli flora, although some decrease is noticeable over time. It is thought that the absence of nutrients in the vagina explains the slow decrease of lactobacilli in these in vitro test results. The claim of Multi-Gyn ActiGel to prevent and treate Bacterial Vaginosis whilst maintaining a healthy vaginal flora is substantiated by this test. It also has a limited (positive) effect directly on killing candida albicans over time. This indicates that the gel is not acting as a disinfectant, but that the candida spores are suppressed by another mode of activity. The manufacter's claim 'counters yeast' is therefore substantiated.
