If your vaginal pH gets disrupted, you might notice odd odors or irritation. Probiotic pH supplements could offer help. Read on to learn more and view our favorite picks.
Quick overview of top pH balance supplements
If you’re dealing with unusual vaginal signs like itching or a persistent smell, an altered pH may be the culprit. This shift in the body’s chemistry can encourage unwanted bacterial growth, among other issues.
pH balance supplements aim to restore a healthy pH by supporting a balanced bacterial environment.
Continue reading to find out more about these supplements, who might gain from them, and our dietitians’ recommendations for the best choices.
Why use pH balance supplements?
pH balance supplements can help reestablish vaginal pH. When vaginal pH is off, you may experience foul odor, itching, and overall discomfort, and you may be more prone to yeast or bacterial vaginosis (BV). Taking pH balance supplements may assist in preserving favorable levels of helpful and harmful bacteria.
These supplements commonly include probiotics — live microbes that, when consumed, can deliver various health advantages. Probiotics may support:
- digestive and gut wellness
- reducing inflammation
- managing mood disorders like depression and anxiety
- immune system function
- skin condition
- support for healthy aging
Different probiotic strains act on different body systems. Researchers have long explored probiotics for vaginal wellbeing.
Nonetheless, despite ongoing study, specialists say additional trials are necessary to firmly link specific probiotic supplements with changes in vaginal pH.
Do probiotics for pH actually help?
The only established treatments for BV and yeast infections are antibiotics and antifungals. However, infections can recur because those therapies may have negative effects on Lactobacilli populations in the vagina, upsetting its balance.
For that reason, some researchers recommend including probiotics as an adjunctive treatment with antibiotics.
A 2022 review of 18 studies reported that adding 1–3 months of probiotic therapy alongside antibiotics may substantially lower BV recurrence compared with antibiotics alone.
Likewise, a 2020 review of 30 studies concluded that using probiotics with antibiotics improved cure rates and reduced relapse of vaginitis. They noted the greatest benefits were seen after about 1 month of supplementation, with effects plateauing around 6 months.
Are probiotics useful if you haven’t taken antibiotics?
Experts are still studying how effective probiotics are for vaginal pH, and results so far are encouraging.
People with a vagina may find Lactobacilli-containing probiotics helpful if they have BV or a yeast infection.
A 2023 trial with 36 women showed that a mix of Lactobacillus acidophilus CBT LA1, Lactobacillus rhamnosus CBT LR5, and Lactobacillus reuteri CBT LU4 significantly improved vaginal dysbiosis — an imbalance between beneficial and harmful bacteria.
Also, a 2022 in vitro study indicates that Lactiplantibacillus plantarum P1 might be useful against bacterial vaginosis caused by Gardnerella vaginalis, a bacterium found in the vagina.
Again, while findings are promising, more research is required to validate probiotic supplements’ effects on vaginal pH.
If you opt to try pH balance pills, consult your physician or a healthcare provider before adding them to your routine. They can evaluate your medical history and advise whether it’s suitable for you.
Begin with a lower colony forming unit (CFU) dose and increase gradually once your body adapts. The ideal time to take a probiotic is with food or about 30 minutes before a meal and two hours before or after antibiotics. It may take several weeks to notice changes.
A note on safety
Supplements, including pH balance pills, are not approved by the Food and Drug Administration (FDA). If you’re unsure about adding a supplement, speak with your primary care physician to confirm it’s safe for you.

- Dose:2 gummies daily
- Certifications :third-party tested for purity and potency
- CFU count:6 billion
- Shelf-stable:yes

Our review
If swallowing capsules isn’t appealing, Lemme Purr Gummies are an alternative.
The gummies are vegan and contain B. coagulans, a strain that may aid recovery from BV. However, the study supporting this strain used 10 billion CFUs, while a serving of these gummies supplies 6 billion.
Besides probiotics, these gummies include vitamin C. A 2011 study showed topical vitamin C could improve vaginal pH, but it’s unclear if oral vitamin C has the same effect.
Lemme reports third-party testing for purity and potency, though the testing organization isn’t named.
Pros & cons
- vegan-friendly
- gluten-free
- third-party tested
- shelf-stable
- easier to take than pills
- may not deliver an effective probiotic dose
- limited evidence that oral vitamin C affects vaginal pH
- contains 3 grams added sugar per serving

What is vaginal pH?
pH measures how acidic or alkaline (basic) something is, on a scale from 0–14. Vaginal pH helps indicate whether the environment is healthy.
A normal vaginal pH is about 3.8–4.5, although this can vary with age.
During reproductive years (roughly ages 15–49), vaginal pH is typically at or below 4.5. Before puberty and after menopause, a healthy pH tends to be higher than 4.5.
An acidic vagina is more protective, creating a barrier that limits overgrowth of harmful bacteria and yeast.
A vaginal pH above 4.5 increases the risk of infections like BV or trichomoniasis (trich).
Factors that can disturb pH include:
- sex without a condom or barrier
- antibiotic use
- douching
- menstrual periods
- inserting unsanitized objects into the vagina
- using products that contain vinegar
Frequently asked questions about pH balance
How can you tell your pH is off?
Frequent UTIs, yeast infections, persistent discomfort, itching, or unusual odor may indicate an imbalanced vaginal pH.
See an OB-GYN for annual exams, and schedule a visit if you have itching, burning, foul smell, or abnormal discharge.
Which vitamins may support pH balance?
Although more study is necessary, vitamins C and D may be particularly important for vaginal health and maintaining a healthy pH.
