Zentonil Advanced.

Zentonil Advanced tablets can be used in dogs for all cases when the liver is known or is expected to require support. Zentonil Advanced tablets contain the pure ingredient, SAMe, with the additional benefit of Silybin in a palatable, easily divided tablet formulation.

Our VetOur vet says... 'Zentonil is recommended by vets for cats who have liver issues, or may be expecting liver issues in the future. Healthy livers produce antioxidants such as glutathione. When liver problems occur, the body doesnt produce enough and thats where this treatment helps. Administer on an empty tummy. Its available in 100, 200 and 400 mg tablets.'
