Have you ever felt as though something is not quite right down there? If so, your vaginal pH may be imbalanced, causing you all sorts of problems - but there's a simple fix. Restoring this balance usually comes down to a few lifestyle tweaks and using targeted products, like those from our pH Balancing and Vaginal Health collections.
This article covers everything you need to know about vaginal pH, including why it matters, what throws it off, and how you can maintain a healthy balance.
What is Vaginal pH?
Your vaginal pH measures the acidity or alkalinity of the environment. A healthy vaginal pH value typically sits between 3.8 and 4.5, meaning it's naturally acidic. This slightly acidic environment is maintained predominantly by Lactobacillus, a "good" bacteria" that produces lactic acid.
When your pH levels stay within the ideal range, your vaginal microbiome thrives. During times of pH imbalance, harmful bacteria and yeast take over, leading to vaginal infections, odor, irritation, or recurring discomfort.
Why pH Balance Matters?
A well-balanced vaginal pH supports:
-
Healthy levels of beneficial bacteria
-
Protection against harmful microbes
-
Odor control
-
Lower risk of vaginal infections, like bacterial vaginosis
When your pH is too alkaline, it often signals that you don't have enough healthy bacteria, which opens the door for discomfort and odor changes. When your acidic pH level is too high, you could experience irritation and vaginal dryness.
Common Causes of Vaginal pH Imbalances
Everyday habits, hormone fluctuations, and certain products can all cause your normal vaginal pH to shift, leading to imbalances. Let's take a closer look at the main culprits.
Sex
Sex, especially unprotected sex, can raise your vaginal pH levels temporarily, as alkaline semen shifts acidity towards neutral. Lubricants with fragrance and additives can have a similar effect.
Menstruation
Blood has a higher pH than the vaginal environment, so it's normal for the vagina to become less acidic during your period. This can increase your susceptibility to odor and discomfort around menstruation.
Antibiotics
Antibiotics kill both "good" and "bad" bacteria, which can reduce Lactobacillus and leave the vaginal microbiome unbalanced.
Hormonal changes
Menopause, perimenopause, postpartum, and hormonal birth control can all alter Lactobacillus levels and moisture. This can impact vaginal acidity and throw off the delicate pH balance.
Products with harsh ingredients
Scented washes, soaps, sprays, and wipes can all impact vaginal health by irritating your intimate area. Even laundry detergent can be a hidden source of irritation.
Tight or synthetic underwear
Airflow is necessary for maintaining a healthy pH balance. Less breathable fabrics and tight underwear can trap heat and moisture, resulting in abnormal vaginal flora.
Stress and lifestyle
Stress can impact immunity and inflammation, which can indirectly affect vaginal balance. Diet, hydration, exercise, and sleep also play a role in maintaining vaginal health.
Medical conditions
Certain health conditions can make you more prone to a pH imbalance. For example, diabetes (especially when blood sugar is poorly controlled) can encourage yeast overgrowth. Immune issues can also make it harder for the body to maintain a stable vaginal microbiome.
Signs Your Vaginal pH May Be Off
Everyone's body is different, but here are some of the most common signs your vaginal pH levels are off:
-
Strong or unusual odor
-
Recurring urinary tract infections (UTIs)
-
Vaginal itching or irritation
-
Burning sensation during urination
-
Vaginal dryness
-
Pain or discomfort during sex
-
Noticeable changes in discharge texture or color
-
Recurring BV or yeast infections
These symptoms don’t always mean infection, but they could indicate that your vaginal environment may need extra support. If symptoms are intense or persistent, contact your healthcare provider as soon as possible.
How to Balance Your Vaginal pH
Now for the good news. Most pH shifts can be corrected through simple habits and the right support, so let's delve into the most effective ways to maintain a normal vaginal pH.
1. Use gentle pH-friendly products
Did you know that your vagina is self-cleaning? This means you don't need harsh scrubs or scented washes to keep it clean. What can help is using gentle products that support the microbiome instead of stripping it.

2. Prioritize probiotics
Probiotics can be incredibly helpful for supporting vaginal health (including pH balance) because they help replenish Lactobacillus (the bacteria responsible for producing lactic acid).
Options include:
-
Daily oral probiotic supplements, such as our Good Girl Probiotics®, for ongoing support.
-
Vaginal suppositories, such as our Flora Power® Suppositories, for targeted help.
3. Avoid douching
Vaginal douching can dramatically shift your microbiome and is one of the fastest ways to upset your natural balance. Since your vagina cleans itself, all you need is a mild, unscented soap or a pH-Balanced Cleanser.
4. Choose breathable underwear
Cotton underwear and moisture-wicking fabrics (like bamboo) help maintain airflow and prevent moisture build-up, promoting a stable vaginal ecosystem.
5. Practice safe sex habits
Not only will using a condom prevent sexually transmitted infections, but it will also keep alkaline semen from altering your vaginal pH levels. You can also:
-
Choose gentle lubricants without any harsh chemicals or fragrances
-
Pee after sex to help maintain overall vaginal health
6. Give your body extra support during your period
Period blood naturally raises the pH levels in your vagina. During menstruation:
-
Change pads and tampons regularly
-
Use unscented menstrual products
-
Try menstrual cups for a non-absorbent option
Leaving tampons in for too long can disrupt the vaginal environment and increase the risk of irritation or infection. Aim to change them every 4–8 hours, and avoid scented varieties, which can irritate delicate tissues and alter your natural balance.
7. Look after your gut health
A balanced gut often means a more stable vaginal environment. Digestion-friendly products found in our Daily Maintenance Collection can help support this connection.
8. Be mindful of medications
If you're taking antibiotics, you should also take probiotics to help offset the temporary imbalance.
Additionally, you should be aware that medications like steroids and immunosuppressants can also impact your vaginal pH. Because they reduce the body’s ability to regulate bacteria and yeast, these medications may increase your risk of imbalance.
9. Manage stress
Stress, lack of sleep, and poor hydration can indirectly affect vaginal balance. Small habits (like journaling, going for walks, and breathing techniques) can help you relax and manage your stress levels.
Short-term immune dips from illness, chronic inflammation, or recovery periods can also make you more susceptible to pH imbalance.
10. Support your vaginal pH with the right food
Your diet plays a surprisingly big role in vaginal health. Nutrient-dense foods like leafy greens, whole grains, berries, plain yogurt, and fermented foods support both gut and vaginal microbiomes. Limiting high-sugar and highly processed foods can also help reduce yeast and bacterial overgrowth.
When Should You See a Doctor?
While pH fluctuations are normal, you should consult a healthcare provider if you experience:
-
Strong, fishy, or sudden odor
-
Yellow, green, or gray vaginal discharge
-
Clumpy discharge with itching
-
Persistent burning or irritation
The above symptoms could indicate bacterial vaginosis, yeast infection, or other conditions that require diagnosis and proper treatment.
FAQs
Can you test your vaginal pH at home?
Yes. Vaginal pH test kits are available over the counter and can provide a quick snapshot of your pH levels. They use a simple swab and color chart to help you determine whether your pH is within the typical range. While these kits can be helpful, they don’t replace professional diagnosis, especially if you’re experiencing strong symptoms.
Can diet affect vaginal pH?
Yes. Sugary or overly-processed foods can encourage overgrowth of harmful bacteria, while probiotic-rich foods can help support a balanced vaginal microbiome.
Closing Thoughts
When balancing your vaginal pH, don't aim for perfection. Just focus on small, supportive habits that help your body do what it's already designed to do. With mindful care, gentle products, and an understanding of what throws things off, you can maintain a healthy vaginal environment all year round.
