Function

  • Hepatoprotective: Silymarin extract has a strong hepatoprotective effect. It helps protect liver cells from damage caused by various toxins, such as alcohol, drugs, and environmental pollutants. It does this by enhancing the antioxidant defense system of the liver, scavenging free radicals, and preventing lipid peroxidation.
  • Antioxidant: It acts as a potent antioxidant, neutralizing harmful free radicals in the body. This helps reduce oxidative stress and prevent damage to cells and tissues, not only in the liver but also in other organs.
  • Anti - inflammatory: Silymarin has anti - inflammatory properties, which can help alleviate liver inflammation. It inhibits the production of inflammatory mediators and cytokines, thus reducing the inflammatory response in the liver.
