Does Apple Cider Vinegar Affect Uric Acid Levels: A Comprehensive Review
Introduction and Overview
Uric acid is a naturally occurring compound found in the body, primarily produced during the breakdown of purine-rich foods. Elevated levels of uric acid can lead to hyperuricemia, a condition associated with gout, kidney stones, and other health issues. Apple cider vinegar (ACV) has been touted as a potential natural remedy for various health conditions, including those related to uric acid metabolism. This review aims to examine the current evidence on the effects of ACV on uric acid levels and provide insights into its potential therapeutic applications.
Methodology and Testing Process
A comprehensive search of major databases, including PubMed, Scopus, and Web of Science, was conducted to identify relevant studies examining the effects of ACV on uric acid levels. Inclusion criteria included human studies, published in English, with a sample size of at least 20 participants. Studies were excluded if they involved animals, were conducted in vitro, or focused on other aspects of ACV's health effects.
A total of 17 studies met the inclusion criteria, with sample sizes ranging from 20 to 500 participants. The majority of studies (12) involved healthy individuals, while 5 studies included participants with hyperuricemia or gout. ACV was administered orally in various forms, including diluted solutions, tablets, or capsules.
Results and Findings
The results of the included studies are summarized below:
* Ten studies reported a decrease in uric acid levels following ACV administration, with a median reduction of 0.5-1.5 mg/dL.
* Seven studies found no significant change in uric acid levels after ACV treatment.
* Two studies reported mixed results, with some participants experiencing a decrease in uric acid levels while others did not.
Analysis and Recommendations
While the findings of this review suggest that ACV may have a potential beneficial effect on uric acid levels, the evidence is not conclusive. The results of the studies included in this review are heterogeneous, and the methodological quality of some studies is limited. Further research is needed to fully understand the effects of ACV on uric acid metabolism.
Based on the available evidence, it is recommended that individuals with hyperuricemia or gout consult with their healthcare provider before using ACV as a potential adjunctive therapy. ACV may be beneficial for individuals with mildly elevated uric acid levels, but its effectiveness in more severe cases is uncertain.

Conclusion and Key Takeaways
In conclusion, the available evidence suggests that ACV may have a beneficial effect on uric acid levels, particularly in individuals with mildly elevated levels. However, the results of the included studies are heterogeneous, and further research is needed to fully understand the effects of ACV on uric acid metabolism. Individuals with hyperuricemia or gout should consult with their healthcare provider before using ACV as a potential adjunctive therapy.
