RHB significantly (p < 0.05) reduced body weight and liver index, inhibited oxidative stress, boosted antioxidant enzymes by increasing the activity and level of SOD and GSH, reduced proinflammatory markers (IL-2, IL-6, TNF-α), and reversed histological alterations induced by NAFLD in rat liver. This evidence concerns the gene SOD1 and metabolic dysfunction-associated steatotic liver disease.
