Lactobacillus crispatus M247 supplement

A supplement containing the probiotic strain Lactobacillus crispatus M247, with potential protective activity. Upon oral administration of L. crispatus M247 supplement, the bacteria in this probiotic supplement colonize the vaginal tract and help to maintain as well as restore the composition of the normal, healthy vaginal flora. The bacteria also produce lactic acid and maintain a more acidic vaginal pH level, which may prevent the colonization and proliferation of pathogenic microorganisms, thereby protecting against genitourinary infections.
