Go to Official WebsiteHow It Works
The 4-in-1 formula works synergistically to address four key areas of women's health through targeted probiotic strains and a supportive prebiotic blend.
Vaginal Microbiota
Clinically studied Lactobacillus strains — L. crispatus, L. gasseri, L. jensenii, L. rhamnosus — help maintain a healthy vaginal microbiome and pH balance.
Urinary Tract Defense
The unique feminine prebiotic blend promotes growth of beneficial bacteria and helps guard the urinary tract from unfriendly bacteria.
Digestive Health
Lactobacillus rhamnosus GG supports digestion, helps reduce occasional upset like gas and bloating, and restores gut balance.
Immune Support
A large portion of the immune system resides in the gut. By nurturing gut microbiome balance, the formula helps bolster natural immune defenses.
