From the Research
Apple cider vinegar supplements are unlikely to cause urinary tract infections (UTIs), and some evidence suggests that certain acidic properties may help prevent UTIs, although the evidence is limited and not directly related to apple cider vinegar. The most recent and highest quality study on the prevention of UTIs was published in 2024 1, which found that cranberry juice consumption was associated with a 54% lower rate of UTIs compared to no treatment, and a 27% lower rate compared to placebo liquid. However, this study did not investigate the effects of apple cider vinegar on UTIs.
Other studies have investigated the use of cranberry products for the prevention of UTIs, with mixed results 2, 3, 4. A 2012 systematic review found that cranberry products did not significantly reduce the occurrence of symptomatic UTIs overall, although some small studies demonstrated a small benefit for women with recurrent UTIs 2. A 2004 review found that cranberry juice may decrease the number of symptomatic UTIs over a 12-month period in women, but the evidence was limited and the optimum dosage and method of administration were unclear 3. A 2007 review found that cranberry products significantly reduced the incidence of symptomatic UTIs in 12 months, particularly in women with recurrent UTIs, but the evidence was based on only four good-quality RCTs 4.
A more recent review published in 2021 discussed the potential benefits of medicinal plants, including apple cider vinegar, in preventing and/or co-treating UTIs, although the evidence was largely based on in vivo and ex vivo animal studies, and human studies were limited 5.
In terms of morbidity, mortality, and quality of life, it is essential to prioritize proper medical treatment for UTIs, including antibiotics prescribed by a healthcare provider, rather than relying on supplements. If you're experiencing UTI symptoms, you should seek medical attention promptly. Additionally, if you're taking apple cider vinegar supplements and notice UTI symptoms, the infection is likely coincidental rather than caused by the supplement. Always consult with a healthcare provider before starting any supplement regimen, especially if you have a history of UTIs or other health conditions.
Some key points to consider:
- Apple cider vinegar supplements are unlikely to cause UTIs
- Cranberry products may have some benefit in preventing UTIs, although the evidence is limited and mixed
- Proper medical treatment, including antibiotics, is essential for UTIs
- Medicinal plants, including apple cider vinegar, may have potential benefits in preventing and/or co-treating UTIs, although more research is needed
- Consult with a healthcare provider before starting any supplement regimen, especially if you have a history of UTIs or other health conditions.
