However, key regulators of these processes remain unexplored. To address this gap, we investigated the mechanisms through which NAR and HES modulate hepatic redox control, persulfidation, and senescence\u2010associated pathways in 24\u2010month\u2010old male Wistar rats. Animals were treated orally with NAR or HES (15\u2009mg\/kg b.w.) for 4\u2009weeks, while control groups remained physiologically intact or received vehicle. Liver tissue was analyzed using a dimedone\u2010based switch method to evaluate overall protein persulfidation (P\u2010SSH), Western blot, qPCR, and histological analysis, including quantification of IHC staining and IF labeling. Our results showed that both citrus flavanones increased total P\u2010SSH levels while exerting distinct regulatory effects on the H\n                    <jats:sub>2<\/jats:sub>\n                    S metabolic network. Only HES upregulated gene expression of H\n                    <jats:sub>2<\/jats:sub>\n                    S\u2010producing enzymes (cystathionine beta\u2010synthase CBS, cystathionine gamma\u2010lyase CSE, and mercaptopyruvate sulfurtransferase MST) and catabolic enzymes (sulfide:quinone oxidoreductase SQR and thiosulfate sulfurtransferase TST), together with CBS protein, whereas NAR decreased CSE protein expression. Both NAR and HES treatment activated the Nrf2 signaling pathway, as evidenced by increased nuclear translocation of Nrf2 in the treated groups. Concurrently, NAR and HES increased Sirt1 expression, which was accompanied by decreases in p16 and \u03b2\u2010galactosidase expression, indicating attenuation of hepatic senescence. Together, these findings highlight a synergistic interplay among persulfidation, H\n                    <jats:sub>2<\/jats:sub>\n                    S metabolism, and Nrf2\/Sirt1 signaling as a key
