LC-G22 powder is a high-potency probiotic additive containing Lactobacillus crispatus (L. crispatus) combined with a specialized cryoprotectant agent to ensure maximum viability and stability.

Lactobacillus crispatus is a common, rod-shaped species within the Lactobacillus genus. It is a hydrogen peroxide (H2O2) producing beneficial microbiota species primarily located in the vaginal flora and the vertebrate gastrointestinal tract. It is particularly recognized for its role in maintaining urogenital health and preventing recurrent urinary tract infections.

Extensive research has evaluated its efficacy in the prevention and treatment of bacterial vaginosis, a condition typically characterized by the depletion of healthy lactobacillus flora. Lactobacillus crispatus plays a crucial role in protecting the host from infections by maintaining an acidic environment and inhibitory substances.
