Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Polyphenols are a broad class of naturally occurring compounds found in plant-based foods and beverages. Their use in supporting or treating kidney stones is primarily grounded in emerging scientific research rather than traditional medical systems. Several in vitro and animal studies suggest that certain polyphenols, particularly those found in green tea, berries, and some herbs, may help inhibit the formation and aggregation of calcium oxalate crystals—the most common type of kidney stone. The proposed mechanisms include antioxidant effects, reduction of oxidative stress in renal tissues, and modulation of urinary factors involved in stone formation. For instance, studies have shown that epigallocatechin gallate (EGCG) from green tea can interfere with the crystal growth process. However, the quality of evidence is limited; most studies are preclinical, and robust human clinical trials are lacking. There is conflicting epidemiological data regarding the impact of polyphenol-rich beverages like tea on kidney stone risk, and some polyphenol-containing foods may also be high in oxalates, which could theoretically increase stone risk in susceptible individuals. Overall, while the idea is scientifically plausible and supported by preliminary data, definitive evidence from well-designed human trials is not yet available, so the current scientific evidence warrants a rating of 2 out of 5.
