Vitamins for pH Balance

Navigate the complexities of women’s health with Human Tonik’s expert guide on vitamins for pH balance. Ensure a healthy vaginal ecosystem and protect against imbalances.

Key Takeaways

  • A good indicator of a woman’s vaginal health is their pH level and ideally should be between 3.8 and 5.0.
  • vaginal pH can be affected by many different factors including diet, age, hygiene, and sexual health.
  • Key nutrients, such as vitamins, minerals, and probiotics, can help promote and maintain a healthy vaginal pH

Women are told to eat a balanced diet, get adequate movement, prioritize sleep, avoid stress, and all the other things to keep us feeling our best. But one key thing for women’s health seems to be missing; vaginal health.

While this is not a common topic and maybe even shied away from by many, it should be considered an important part of maintaining a healthy lifestyle if you are a woman.

Those who struggle with their vaginal health should look at diet as the first line of defense. Supplements, such as Human Tonik, can provide scientifically dosed products to help support a healthy vaginal pH in those needing a little extra help.

Human Tonik is committed to creating quality products that help promote health through a wide range of research-backed ingredients. Their products are all third-party tested for quality and purity and they provide full ingredient transparency.

Understanding pH Balance and Vaginal Health

A good indicator of a woman’s vaginal health is their pH level. A healthy vaginal pH is between 3.8 and 5.0. which is moderately acidic to protect the vaginal lining from pathogens. Unfortunately, this pH can be affected by a variety of factors (Source). 

Vaginal pH levels that are not maintained within a normal range can put you at risk for developing a variety of vaginal infections, including bacterial vaginosis (BV), yeast infections, chlamydia, gonorrhea, herpes simplex virus type 2, HPV, and HIV (Source).

Vaginal pH balance can be affected by a variety of factors, including diet. This means that some of the foods you choose can help promote a healthy vaginal pH or cause alterations in these levels. Additionally, vaginal pH can be impacted by age, unprotected sex, antibiotic use, vaginal douching, and menstruation. 

Unbalanced vaginal pH can present difficulties with fertility. Sperm requires more alkaline conditions to survive so a highly acidic vaginal pH may make it difficult for fertilization (Source).

Vaginal pH imbalances may also present with an unexpected change in odor, particularly a foul, fishy smell which is often associated with BV. There may also be an increase or a change in the color or texture of vaginal discharge, itchiness, pain during or after sex, and burning during urination.


Key Vitamins for Vaginal Health and pH Balance

Aside from lifestyle factors, key nutrients, such as vitamins, minerals, and probiotics, can help promote and maintain a healthy vaginal pH. Below are some of the best vitamins for vaginal health that can aid in maintaining vaginal pH balance.

Vitamin D

Vitamin D plays a significant role in our body’s immune health which is why it is one of the best vitamins for female pH balance. Vitamin D may also play a big role in vaginal health, particularly when it comes to vaginal dryness which can commonly occur in those going through menopause  (Source).

In a review of 6 studies on vitamin D supplementation in postmenopausal women, vitamin D administration improved the growth and differentiation of vaginal cells, improved pH levels, and decreased dryness [Source].

Not only is this impactful in postmenopausal women, but it may also help improve overall vaginal health in other age groups. 

Vitamin D also helps to support immune function and may reduce the risk of certain vaginal infections such as urinary tract infections (UTIs) [Source].

Vitamin C

Vitamin C acts as an antioxidant and antimicrobial that can help to protect your body’s cells (including vaginal cells) from harmful free radicals and pathogens. Vitamin C also plays an essential role in the growth and repair of your vaginal tissue, granting it a spot in the category of best vitamins for pH balance. 

Vitamin C can also help promote good bacteria naturally found in the vaginal lining and may be beneficial in the treatment of BV due to its effects on vaginal pH. According to one study, regular use of ascorbic acid vaginal tablets (vitamin C) for at least 6 months reduced the risk of recurrent BV from 32% to 16% [Source].

Locally applied vitamin C has also been shown to have pH-reducing effects in those suffering from higher vaginal pH levels [Source].

Folic Acid

Folic acid, also known as vitamin B9, is associated with potential improvements in immune function that may protect against vaginal conditions such as BV. Research has found that folic acid may also indirectly improve the immune function of female genital mucosa through intestinal immune regulation [Source].

Additionally, vitamin D and folic acid deficiencies were linked to higher chances of developing DV due to their positive effects on immunity [Source].

Natural Supplements for Vaginal Health

Aside from the key vitamins mentioned above, probiotics and sea buckthorn oil may be beneficial supplements to help treat common vaginal issues and promote vaginal health. 

Lactobacillus Rhamnosus and Lactobacillus Acidophilus are probiotic strains that have been linked with providing benefits in improving and maintaining healthy vagina flora. Probiotics are essential in maintaining the fragile microbiome of the vagina. With a well-established microbiome comes improved immune defense against various diseases including cervical cancer [Source, Source]. 

Sea Buckthorn Oil is another supplement that can aid in vaginal health by promoting lubrication and maintaining a healthy vaginal environment. This oil is rich in essential fatty acids that help strengthen the skin barrier and maintain moisture [Source].

For those looking for more bang for their buck, consider Human Tonik Supergreen Tonik Powder or Synbio Tonik. 

While these supplements are not marketed directly for vaginal health, they both contain many key ingredients needed to maintain a healthy vagina and support overall wellness including essential probiotic vitamins for pH balance.

Lifestyle and Dietary Factors Affecting Vaginal pH

As mentioned above, vaginal pH can be affected by many different factors including diet, age, hygiene, and sexual health. 

Lifestyle factors can be easily adjusted to promote a healthy vaginal pH. For example, avoid vaginal douching which can cause irritation and alter the pH of the vagina, which is self-cleaning. Instead, gently clean the area around the vagina (the vulva) with warm water.

Choose breathable underwear, such as cotton, and avoid spending long periods of time in damp undergarments, such as swimming or excessive sweating. Practice safe sex practices and make sure you are wiping correctly after a bowel movement (front to back) to avoid bacterial spread from feces.

Dietary factors can also be adjusted to improve your vaginal pH. Choose more foods or supplements that contain probiotics to provide benefits for the vaginal microbiome. Choose a balanced diet rich in vitamins, minerals, and antioxidants.

Avoid a diet high in processed foods and added sugars as this can alter your body’s vaginal pH levels and increase the risk for various conditions that can also affect your vaginal pH, such as diabetes [Source].

Preventing and Addressing pH Imbalance

Lifestyle factors such as the ones mentioned above are the first line of defense against preventing vaginal pH imbalance. However, life happens and sometimes we unintentionally put ourselves at risk.

Suppose you are experiencing signs and symptoms of potential vaginal pH imbalance. In that case, it’s important to seek medical advice to rule out any potential underlying conditions and ensure the symptoms you are experiencing are actually a result of pH imbalance.

There are over-the-counter pH testing strips that you can use to see if this may be a cause for your symptoms; however, these are not always accurate.

If you are experiencing new onset burning, itchiness, odor, increased vaginal discharge, or a new color or texture of discharge it’s important to consult your physician immediately as this could be a result of an infection that needs to be treated.

Bottom Line

Diet and lifestyle factors play a huge role in maintaining a healthy vaginal pH which protects against disease and irritation. Unfortunately, sometimes our diets are lacking due to reasons out of our control. This is where supplements, such as vitamins for women’s pH balance, can help fill in nutritional gaps to ensure we are getting everything we need to maintain our vaginal health.

If you are considering a natural supplement for maintaining vaginal pH balance, be sure to choose from a trusted brand that offers third-party testing for quality and purity as well as full ingredient transparency, such as Human Tonik products.
