Jørgensen MR, et al. (2020). Lactobacillus rhamnosus strains of oral and vaginal origin show strong antifungal activity in vitro. Your vagina naturally is home to different types of healthy, acid-producing bacteria. To prevent dryness and maintain a chemical balance, your vagina also regularly produces fluid. That fluid contains acids. The pH scale ranges from 0 to 14. A pH of less than 7 is considered acidic, while a pH over 7 is considered alkaline (basic). A “normal” vaginal pH is moderately acidic, hovering between a pH of 3.8 and 4.5.

Polatti F, et al. (2006). Vaginal pH-lowering effect of locally applied vitamin C in subjects with high vaginal pH.There are around 100 trillion probiotics in the human body (also known as good bacteria) going around our intestines and stomachs. F. Polatti, M. Rampino, P.Magnani, and P. Mascarucci, “Vaginal pH-lowering effect of locally applied vitamin C in subjects with high vaginal pH,” Gynecol. Endocrinol., vol. 22, pp. 230-4, April 2006. We have included probiotics with different strains, including multiple options with a blend of bacteria strains. Use and dosage Normal vaginal pH (3.8-4.5) is regulated by Lactobacillus through hydrogen peroxide, lactic acid, and glycogen. However, an overgrowth of Gardnerella vaginalis can disrupt the balance of the vaginal ecosystem, leading to a condition called dysbiosis. Once the probiotics enter your body, they are thought to attach to the vaginal cells. The probiotic bacteria produce substances that destroy infection-causing bacteria or yeast, which may restore the natural vaginal pH [3].

Nelson TM, et al. (2018). Cigarette smoking is associated with an altered vaginal tract metabolomic profile. Overall, we would recommend pH balance pills to balance out vaginal pH levels as well as lower inflammation and help with gut and digestive health.
