Studies have shown that apple cider vinegar can lower levels of Candida albicans (the fungus that causes yeast infections) in test tubes. However, there isn't yet enough human research to recommend it as a safe and effective treatment for a yeast infection.

White vinegar is a natural antiseptic, which is why applying it to an infected area can help clear up the infection. White vinegar can also be beneficial in odors commonly associated with yeast infections. White vinegar treats yeast infections because it has a pH level of 5.5, which makes it extremely acidic.

Apple cider vinegar has antibacterial and antifungal benefits. Consuming it could potentially make your body less hospitable to fungus. However, more research is needed to determine whether it can successfully treat yeast infections.

“There is little evidence related to the efficacy of apple cider vinegar to treat yeast infections, and the studies that are out there are not robust,” Dr. Linhorst says.
