Key takeaways

  • Probiotics, especially Lactobacillus species, are dietary supplements that play a crucial role in maintaining vaginal health by adhering to the vaginal lining and preventing pathogenic colonization, thus supporting a balanced vaginal microbiota.

  • Specific probiotic strains of Lactobacillus, such as L. acidophilus, L. rhamnosus, L. reuteri, L. crispatus, L. gasseri, and Bifidobacterium lactis, have been identified as good bacteria, with health benefits like maintaining a low vaginal pH and preventing infections.

  • Probiotics can support digestive health and help reduce the recurrence of bacterial vaginosis and vaginal yeast infections when used alongside standard treatments, but they are not a standalone cure.

  • When taking probiotics for vaginal health and wellness, it’s important to select products based on clinical evidence supporting specific Lactobacillus strains, considering factors such as the need for refrigeration and daily dosage requirements.

If you’re wondering how to support vaginal health naturally, you’re not alone. Many people turn to probiotics to help restore gut health and balance of microorganisms, which in turn may reduce the risk of common infections like bacterial vaginosis and yeast infections. But with so many options available, choosing the best probiotic for vaginal health can be confusing. Here’s what you need to know to pick the right one for you.

Probiotics and vaginal health

A balanced vaginal microbiome is a hot topic in women’s health and is an extension of a strong gut microbiome. Beneficial microbes, such as prebiotics and probiotics, help protect against infections, support pH balance, and contribute to overall reproductive health. The dominant bacteria in a healthy vagina are from the Lactobacillus genus, which help maintain an acidic pH (around 4.0) that inhibits the growth of harmful pathogens.

Probiotics can help restore the gut microbiota’s dysbiosis when it’s disrupted, whether due to antibiotics, stress, hormonal changes, or dietary changes. They achieve this by producing substances such as lactic acid and hydrogen peroxide, which make the vaginal environment less hospitable to harmful bacteria and yeast.

Probiotics may not cure an active infection alone, but research shows that they can support treatment and reduce recurrence when used in conjunction with antibiotics or antifungals. For example, adding probiotics to metronidazole treatment for bacterial vaginosis has been shown to reduce recurrence rates.

6 probiotics for vaginal health

Here are six strains with research-backed benefits for vaginal health:

1. Lactobacillus acidophilus

One of the most well-known probiotics, L. acidophilus, helps maintain a healthy pH and supports the growth of beneficial bacteria. It’s found in fermented foods such as yogurt, miso, kimchi, and tempeh, as well as in standalone supplements.

2. Lactobacillus rhamnosus

Particularly strains GR-1 and LbV 96, which have shown effectiveness in preventing and treating bacterial vaginosis and yeast infections.

3. Lactobacillus reuteri

Often paired with L. rhamnosus (GR-1), this strain has been shown to reduce the recurrence of infections and support a balanced vaginal microbiome.

4. Lactobacillus crispatus

A naturally occurring strain in the vaginal flora. In clinical trials, it significantly reduced the recurrence of bacterial vaginosis when used after antibiotic treatment.

5. Lactobacillus gasseri

This strain helps lower pH and prevent overgrowth of harmful microbes. Strain LbV 150N is commonly included in vaginal health supplements.

6. Bifidobacterium lactis

Though better known for digestive support, B. lactis also contributes to vaginal health by enhancing the mucosal barrier and supporting immune function.

Choosing the best probiotics for vaginal health

When selecting a probiotic supplement, look for products that include a mix of Lactobacillus and Bifidobacterium strains, especially those listed above. Other factors to consider include:

  • CFU (colony-forming unit) count: Aim for 1 billion CFUs or more.
  • Storage requirements: Some products require refrigeration, while others are shelf-stable.
  • Dose frequency: Typically, once or twice daily.
  • Additives: Select gluten-free and allergen-free options if necessary.

Two popular and effective options include:

Tips for optimizing vaginal health with probiotics

  • Eat fermented foods: Yogurt, kefir, sauerkraut, kimchi, miso, and kombucha are great sources of probiotics.
  • Follow the label: Take your supplement as directed, paying special attention to whether it should be taken with food.
  • Be patient: It may take a few weeks to notice benefits. Allow at least a month and stay consistent with use.
  • Maintain good hygiene and a balanced diet: Avoid using scented products and opt for a fiber-rich diet.

FAQs about vaginal probiotics

Can probiotics cure existing vaginal infections?

No, but they may improve outcomes when used alongside prescribed treatments and reduce future infections.

Are there side effects to using probiotics for vaginal health?

They’re generally safe. Some people may experience mild digestive discomfort, such as bloating. Those with weakened immune systems should consult a healthcare provider before initiation, as supplementation with lactobacillus strains is a live microorganism.

Can pregnant women use probiotics?

Yes, but it’s always best to talk to a healthcare provider first. Current evidence shows no significant risk in healthy individuals.
