NEW! Denestra (S-adenosylmethionine) is a nutritional supplement for dogs and cats that helps support liver, joint, and cognitive functions. Liver problems in pets can be a major concern particularly when the liver faciliates waste disposal and the production of antioxidants. Denestra increases the amount of Glutathione, a naturally occurring antioxidant in pets that has shown to promote liver cell regeneration as well as protect against toxins and free radicals. Denestra is also effective against arthritis and works well as an antidepressant. It can help with reducing pain, stiffness, and inflammation associated with joint problems.
