Probiotics Studied For Recurrent Urinary Tract Infections

Lactobacillus rhamnosus GR-1 is the world's most clinically researched probiotic strain for women's vaginal and urinary tract health, with over four decades of published evidence behind it. Originally isolated from the urethra of a healthy woman, this powerhouse strain is uniquely designed to travel from your gut all the way to your vaginal tract — where it gets to work defending your body. If you deal with recurring BV, yeast imbalances, or frequent UTIs, this strain is the one the science keeps pointing to.

Lactobacillus reuteri RC-14 is one of the most researched probiotic strains for women's intimate health, working deep in the microbiome to crowd out the harmful bacteria and yeast that cause recurring infections. Think of it as a tiny bodyguard that reclaims territory in the vaginal tract and keeps the peace. Taken daily, it helps restore the natural bacterial balance that protects against bacterial vaginosis, yeast infections, and urinary tract infections.

Lactobacillus crispatus CTV-05 is a precision vaginal probiotic — essentially a targeted reinforcement squad for your intimate microbiome. Clinically studied to help keep bacterial vaginosis (BV) from coming back after antibiotic treatment, it works by re-establishing a healthy, acidic environment that naturally discourages harmful bacteria. If BV keeps disrupting your life, this strain is the most researched live biotherapeutic available to help restore lasting balance.
