Medically reviewed by Dr. Dimitar Marinov, September 15, 2023

For this article, I have looked into clinical evidence and user reviews to provide you with a satisfactory answer to the question of how probiotics cause more discharge.

As an individual who has struggled with maintaining good gut health, I know firsthand how important it is to keep your microbiome in check. One area that is often overlooked is the vaginal microbiome, which plays a crucial role in maintaining vaginal health.

In recent years, probiotics have gained popularity as a natural way to promote better gut health, but what about their impact on vaginal health?

In this post, we will explore the relationship between probiotics and vaginal discharge, and how taking probiotics may actually help improve vaginal health. 

Key Highlights
  • Probiotics can positively affect vaginal discharge if taken within the recommended limit.
  • An abundance of good bacteria in the vaginal microbiome can counteract the growth of infectious microorganisms.
  • Probiotics may normalize abnormal discharge and improve the vaginal bacterial count.
  • On the other hand, overdosing on probiotic microorganisms may set the vaginal microbiome off balance and cause excessive discharge with an altered consistency.
  • Culturelle® Women’s 4-in-1 Protection Capsules is a recommended probiotics supplement for vaginal health.

An abundance of good bacteria in your vaginal microbiome counteracts the growth of infectious microorganisms by various mechanisms.

So, in this article, you will find how probiotics may affect your discharge characteristics and some top supplements that you may use to support vaginal health.

Keep reading to know the details.

Do Probiotics Affect Discharge?

Yes, probiotics may positively affect vaginal discharge if taken within the recommended limit. An unusual vaginal discharge mostly occurs from infections or can be caused due to dysbiosis (imbalance) in the vaginal microbiome. And in this case, the probiotics may help restore healthy microbial diversity, which prevents and treats the symptoms.

For instance, Lactobacillus strains produce lactic acid, which makes the vagina’s pH acidic (3.8 to 4.5) and inhibits the growth of yeast and other pathogenic organisms that might cause abnormal discharge.

My research on how probiotics may affect discharge revealed:

Probiotics May Normalize Abnormal Discharge

Bacterial vaginosis and aerobic vaginitis are two vaginal infections that mainly cause discharge of unusual appearance, consistency, and smell.

According to the NHS, bacterial vaginosis may cause a greyish-white or milky discharge that is thin, watery and has a fishy odor.

Similarly, aerobic vaginosis is most commonly associated with E. coli. It may manifest symptoms like a sticky, yellowish, or green discharge with a rotten odor, along with symptoms of vaginal inflammation.

To look for a cure, a clinical trial tested the effectiveness of the L. fermentum and L. plantarum probiotic strains in these conditions.

The results showed that these probiotics significantly improve the uncomfortable symptoms by stabilizing the vaginal flora and effectively counteracting acute Gardnerella infections.

Additionally, they may also provide long-term protection and reduce recurrent infections by preventing the colonization of Gardnerella or E. coli

Probiotics May Improve The Vaginal Bacterial Count

Probiotic intake supports the healthy vaginal microbiota status, which protects against the symptom of altered discharge.

This was proven by a 2019 randomized control trial that recruited forty healthy women to evaluate the safety and tolerability of Lactobacillus crispatus strains in them.

In this trial, the study group was fed 109 CFU of three strains of L. crispatus probiotic for one week.

The results showed that probiotic intake reduced the Gardnerella vaginalis counts and the median concentration of bacterial counts in the intervention group as compared to the control group, who were fed a placebo.

These findings are significant because both the total bacterial and G. vaginalis concentrations are increased in bacterial vaginosis.

Probiotics May Normalize Smell And Irregularity In Vaginal Discharge

Apart from the clinical evidence, women on Reddit have shared how the characteristics of their vaginal discharge have improved greatly with probiotic intake.

So, here are some stories that I picked for you.

  • Oranbot Redeemed Her Reproductive Health And Confidence With Probiotics

A Reddit user, Oranbot, shared in her post that she was suffering from vaginal dryness, smelly discharge, and recurrent vaginal and urinary tract infections.

But only after two weeks of using the Viva Naturals “Probiotics for Women – 50 Billion CFU” has she regained the wetness down there, and her discharge has also got less smelly.

  • A Pot Of Yogurt And A Probiotic Pill Cured Cucumberrella’s BV Symptoms

Cucumberrella wrote in her Reddit post that she suffered from bacterial vaginosis for more than 7 years and tried antibiotics, boric acid suppositories, and even probiotic pills, but nothing worked.

However, when she combined her 90 billion women’s probiotic supplements with yogurt, she noticed a 60% improvement in her symptoms.

This probiotic combo helped greatly to reduce the smell and amount of her discharge.


It’s important to note that there is no way to know if these experiences were in fact real, or if the aforementioned posts were sponsored. 

Can Too Much Probiotics Cause Discharge?

Yes, overdosing on probiotics may cause an overgrowth of lactobacilli bacteria, which may resultantly cause excessive discharge. In the worst-case scenario, lactobacilli overgrowth may cause vaginal Lactobacillus or cytolytic vaginosis.

Here, vaginal Lactobacillus is characterized by a profuse, thick, white, and curdy discharge that gives a sensation of vaginal wetness.

Compared to this, cytolytic vaginosis manifests symptoms like increased discharge with a cottage cheese appearance.

I further looked into Reddit to check if probiotics cause more discharge in users, and here is one piece of evidence that proves my stance.

Does Taking Probiotics Cause More Discharge? – Reddit

Markdemaco started this Reddit thread to ask if we can overdo probiotics because she obsessively took probiotic pills and foods after her doctor recommended she take them to cure her yeast infection.

Instead, they have rendered her prescription of Diflucan (anti-fungal) ineffective against her infection.

To this, a replier’ sunkissedpride’ shared that it is highly possible because a week after she overdosed on yogurt, 2 probiotic supplements, and intravaginal probiotics, she was diagnosed with bacterial vaginosis (which she rather suspects to be cytolytic vaginosis/lactobacillus overgrowth syndrome).

Although she got better after giving up on probiotics and with treatment, she is still battling some symptoms like excessive vaginal discharge and itchiness.


It’s important to note that all this information is speculative, and there is no way to know what the actual cause of her symptoms is until she receives a definitive diagnosis from a medical doctor.

Probiotic For Vaginal Odor – Does It Work Or Make It Worse?

Probiotics may help with vaginal odor rather than making it worse.

As mentioned above, probiotics may reduce the odor of vaginal discharge if it is caused by infections like bacterial vaginosis.

In the worst case, overconsuming women’s probiotics may cause lactobacillus or cytolytic vaginosis. And neither of these conditions is an infection, and although they are characterized by an excessive discharge, it is odorless.

If you are convinced to use probiotics to boost your vaginal health, then here are my top five recommendations to help you start off.

1. Garden of Life Raw Probiotics Vaginal Care probiotics

Can Probiotics Cause Brown Discharge?

No, there is no evidence to support this case. Instead, brown discharge may be linked to bacterial vaginosis.

Can Probiotics Make BV Worse?

No, most studies have found that probiotics are an effective treatment for bacterial vaginosis (BV) and don’t usually cause side effects.

How Long Does It Take For Probiotics To Clear Up BV?

 A review of different clinical trials concluded that in most cases, intravaginal administration of probiotics might cure BV in 6-12 weeks Whereas, oral probiotics may take as long as two months. Nonetheless, probiotics may take at least 2-weeks to work.

Bottom Line on Probiotics And Vaginal Discharge

To conclude, the answer to whether probiotics can cause excessive discharge is ‘yes.’ The reason is that, like the gut or skin microbiome, the vaginal microbiome also holds prime importance in maintaining genitourinary health.

All in all, vaginal health is mostly attributed to probiotic species belonging to the Lactobacillus family (but other microorganisms also play a role).

Furthermore, the clinical investigations that evaluated probiotic use for enhancing vaginal health have rendered positive outcomes, especially with L .acidophilusL. rhamnosus, and L. reuteri strains.

Therefore, the world is seeing a shift towards the trend of using probiotics for treating vaginal issues like smelly or excessive discharge.  

Nonetheless, this doesn’t mean that overstuffing probiotics won’t have opposite consequences.

So, always ask a doctor to recommend a dose that suits your needs well.
