In this work we have therefore demonstrated the systemic antioxidant effect mediated by FPP®: in fact, treating mice every day with FPP® at the concentration of 200 mg/Kg/mouse, the total ROS levels in the blood decreased (p < 0.0001) in a directly proportional way to the size of the tumor, while the levels of plasma GSH and SOD-1 increased (p < 0.0001) inversely to the size of the tumor. Here, SOD1 is linked to neoplasm.
