Why Strains Matter

Not all probiotics are created equal. When it comes to vaginal health, strain specificity matters far more than CFU count alone. Two strains stand apart from all others: Lacticaseibacillus rhamnosus GR-1™ and Limosilactobacillus reuteri RC-14™.

These are the world's most extensively researched urogenital probiotic strains, scientifically studied for their effects on vaginal flora health across 30+ years of clinical investigation and more than 60 peer-reviewed scientific publications. Bio-K+ Women’s Health Probiotic is formulated specifically with both GR-1™ and RC-14™.

Not every probiotic on the market contains these strains by name. Bio-K+ does, and the distinction matters when choosing a vaginal flora probiotic.

What is the vaginal microbiome?

The vaginal microbiome is the community of microorganisms that naturally inhabit the vaginal environment.

Targeted probiotic strains such as GR-1™ and RC-14™ help support and maintain this natural balance.†
