Comparing Boric Acid and Lactic Acid Suppositories

Comparing Boric Acid and Lactic Acid Suppositories

Two commonly used options to help prevent reoccurring vaginal infections are boric acid and lactic acid suppositories. 

Understanding Boric Acid Suppositories:

Boric acid suppositories have gained popularity as an alternative remedy for addressing vaginal discomfort, including to help prevent infections such as bacterial vaginosis and yeast infections. However, boric acid is a chemical compound that should be used with caution due to potential risks. Boric Acid should never be taken orally as it can be toxic if ingested.

Why Lactic Acid Suppositories Are Better:

  1. Natural Component:

Lactic acid, naturally found in the vaginal flora, plays a vital role in maintaining a healthy pH balance. Opting for lactic acid suppositories ensures you're introducing a substance that is already present in the vaginal environment, making it less likely to disrupt the delicate balance.

  1. pH Regulation:

Lactic acid maintains the vaginal pH at an optimal acidic level, typically between 3.8 and 4.5. This slightly acidic environment is crucial for preventing the growth of harmful pathogens that could lead to infections.

  1. Preserving Vaginal Microbiome:

Lactic acid suppositories support the growth of beneficial lactobacilli bacteria, which constitute a significant portion of the vaginal microbiome. These bacteria are crucial for preventing infections and maintaining a healthy vaginal environment.

  1. Gentle and Effective:

Lactic acid suppositories offer a gentle approach to promoting vaginal health. Their natural composition minimises the risk of adverse reactions or irritation.

  1. Support for Discomfort:

Lactic acid suppositories can also aid in alleviating common vaginal discomforts, such as itching, irritation, and abnormal discharge. By restoring the optimal pH balance, these suppositories contribute to a healthier and more comfortable vaginal environment.


When considering options for maintaining vaginal health, the choice between boric acid and lactic acid suppositories becomes clear. Lactic acid, is a natural component of the vaginal flora. It helps regulate pH levels and preserve the vaginal microbiome to provide gentle and effective relief from discomfort. As always, consulting with a healthcare professional before introducing any new product is advisable to ensure it aligns with your specific needs and health considerations.
