The two studies provided do not contain research relevant to lemon water or kidney health — one examines surface transmission of SARS-CoV-2 in public spaces in Peru, and the other investigates whether gut-derived polyphenol metabolites can cross the blood-brain barrier. As a result, no evidence-based summary connecting lemon water to kidney health can be synthesized from the available sources. Readers interested in this topic should seek out studies specifically examining citrate supplementation, urinary pH, or kidney stone prevention in the context of lemon or citrus consumption. The current linked studies do not support any conclusions in this area.
