Consequently, the reduction of uric acid levels has become particularly crucial. The utilization of dietary supplements presents potential adjunctive treatment options for individuals with gout. Certain dietary supplements are purported to aid in the reduction of uric acid levels and are highly preferred by patients due to their affordability, ease of use, and accessibility. The aim of this article was to compare the efficacy and safety of dietary supplements in modulating uric acid, oxidative stress, and lipid metabolism in patients with hyperuricemia or gout, using a comprehensive network meta-analysis (NMA) approach.</p><p><strong>Methodology: </strong>A comprehensive search was performed across both Chinese and English databases to identify randomized controlled trials (RCTs) examining the efficacy of dietary supplements in reducing uric acid levels. Network meta-analysis was conducted using Stata 16.0 software, while RevMan 5.3 software was employed to assess the quality of the literature and evaluate the risk of bias.</p><p><strong>Result: </strong>A total of 30 RCTs, encompassing 44,972 patients, were conducted.
