The Active Ingredient Is: Lactobacillus (Probiotic Bacteria)

Lactobacillus strains are probiotic bacteria commonly used to support genitourinary health and a balanced vaginal microbiota.

This formulation relies on a multi-strain probiotic blend delivered with InTactic acid-stable technology to promote viability through the digestive tract and support friendly gut and mucosal ecosystems.

What Does Lactobacillus Do?

Lactobacillus strains can help maintain a healthy vaginal microbiota and acidic vaginal environment, which are described as normal physiological functions in EFSA-aligned guidance.

Dr. Falagas of NIH found that probiotic bacteria may help lower recurrence rates of vaginal infections and support vaginal health through colonisation and immune interactions.
