Efficacy of Milk Thistle Extract

The core efficacy of milk thistle extract focuses on liver protection and repair. Its active component, silymarin, neutralizes free radicals through antioxidant mechanisms, inhibits lipid peroxidation, and reduces liver cell damage. It also stabilizes liver cell membranes, promotes protein synthesis, and accelerates liver cell regeneration. Clinical studies indicate its supportive role in improving conditions such as alcoholic liver disease, drug-induced liver injury, non-alcoholic fatty liver disease, and viral hepatitis. Additionally, silymarin exhibits anti-inflammatory effects, regulates cholesterol metabolism, mildly lowers blood sugar, and shows potential antitumor activity, demonstrating diverse value in the management of chronic metabolic diseases.
