Best Probiotics for Yeast Infection: Lactobacillus Strains and More

Yeast infections, particularly those caused by Candida species, are a common concern. While antifungal medications are typically prescribed for treatment, the role of probiotics in managing these infections has gained attention. This article delves into the effectiveness of probiotics, focusing on specific strains that have shown promise in treating and preventing yeast infections.

Understanding Probiotics and Yeast Infections

Yeast infections are primarily caused by an overgrowth of Candida, with Candida albicans being the most common strain. Probiotics, especially certain Lactobacilli strains, have been found to be potentially effective in both treating and preventing these infections. They work by creating an acidic environment in the vaginal tract, inhibiting the growth of pathogenic fungi and bacteria.

Key Probiotic Strains

  1. Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14: These strains are particularly notable for their potential in treating and preventing yeast infections. They help maintain a healthy balance of microflora in the vaginal area, making it less hospitable for Candida growth.
  2. Saccharomyces boulardii: While not as directly related to vaginal health, this probiotic yeast is known for its overall benefits to gut health and may indirectly contribute to a healthier immune response against yeast infections.

Clinical Evidence

Studies have shown that women using Lactobacillus-containing probiotics, either through oral consumption or vaginal application, experienced a reduced rate of yeast reinfections. One study involving yogurt consumption indicated a statistically significant reduction in yeast infection recurrence compared to a control group.

Forms of Probiotics

Probiotics are available in various forms, including tablets, capsules, powders, vaginal suppositories, and creams. The choice of form depends on individual preferences and specific health considerations.

Safety and Side Effects

Probiotics generally have a strong safety profile with minimal side effects. The most common side effects include gastrointestinal discomforts, such as gas and bloating. They are considered safe for use by pregnant women, children, and men, broadening their applicability beyond female vaginal health.


Probiotics, particularly certain Lactobacillus strains, offer a promising supplementary approach to managing yeast infections. Their ability to maintain a healthy vaginal microbiome makes them a valuable tool in both treatment and prevention. However, it is essential to consult with healthcare professionals for personalized advice and treatment plans.
