Renum plays a protective role against kidney damage secondary to urinary tract lithiasis. It is a combination of Coenzyme Q10 (ubiquinone) with the four tocopherol forms of vitamin E: alpha-tocopherol, beta-tocopherol, gamma-tocopherol and delta-tocopherol (tocopherol). It can be administered mixed with the ration or directly into the animal's mouth. It is recommended to be administered together with the ration to ensure its correct absorption.
