Evidence-backed FAQ
Do probiotics help bacterial vaginosis?
In meta-analyses of randomized trials, participants assigned to Lactobacillus-based probiotic regimens were more likely to no longer meet bacterial-vaginosis diagnostic criteria at follow-up than participants assigned to placebo, but the evidence was weak and heterogeneous.[1], [2]
What the evidence shows
Pooled trials did not show extra adverse events compared with control. In some analyses, regimens studied alongside antibiotics produced somewhat better follow-up outcomes than antibiotics alone.[1], [2]
Important limitations
Trials differed in strain, route, dose, and follow-up, no standardized regimen was established, and reviewers called for larger, more uniform studies. This does not replace diagnosis or established treatment.[1], [2]
