Certain probiotic strains like Lactobacillus rhamnoses, L. reuteri, L. crispatus, and L. gasseri can help maintain a healthy vaginal pH and microbiome. Research indicates that Lactobacillus rhamnosus Gr-1 and Lactobacillus reuteri Rc-14 are among the most beneficial probiotic strains for supporting vaginal health and may reduce risk of urinary tract complications. Many high-quality clinical trials have evaluated the efficacy of L. rhamnosus Gr-1 and L. reuteri Rc-14 for supporting urogenital and vaginal health in women. Probiotics could help alleviate symptoms like vaginal dryness, hot flashes, and sleep issues during menopause, by supporting gut and vaginal health. Like general probiotics, women's formulas can promote better digestion, reduce bloating and gas, and support a healthy gut microbiome. A balanced gut microbiome supported by probiotics may boost immune function.
