Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lactobacillus jensenii is one of the dominant species of Lactobacillus found in the healthy human vagina. Its use in supporting or treating vaginitis is primarily backed by scientific evidence, though the quality and quantity of evidence are moderate, earning it a score of 3 out of 5. Research has shown that L. jensenii contributes to maintaining vaginal health by colonizing the vaginal mucosa and producing lactic acid and hydrogen peroxide, which lower the vaginal pH and inhibit the growth of pathogenic bacteria and yeasts commonly responsible for vaginitis, such as Gardnerella vaginalis and Candida albicans. Several in vitro studies and some clinical trials have demonstrated that probiotics containing L. jensenii can help restore the normal vaginal flora after disruptions caused by antibiotics or infections. For example, a 2011 study published in "Microbes and Infection" found that L. jensenii adheres well to vaginal epithelial cells and can outcompete pathogens.

However, large-scale, high-quality clinical trials specifically evaluating L. jensenii as a mono-therapy for vaginitis are limited. Most probiotic preparations used in studies contain a mix of lactobacilli species, making it difficult to attribute effects to L. jensenii alone. Despite this, the current body of evidence supports the rationale for its use in the prevention and adjunctive management of vaginitis, particularly bacterial vaginosis and recurrent vaginal infections. Ongoing research may further clarify its efficacy and optimal use.
