Denosyl 225 mg Chewables 30 Count

How does Denosyl work?

Liver Information

Denosyl has been shown to markedly increase liver glutathione levels,1,2 an important compound for liver health formed when SAMe is metabolized .

Denosyl has also been shown to help protect liver cells from cell death3,4 and may help cell repair and regeneration.5

Brain Information

While best known for supporting the liver in dogs and cats Denosyl also has a place in supporting brain health! Denosyl could help your best friend live a longer, healthier life.

Research is looking into dog aging and associated decreases in levels of SAMe (S-Adenosylmethionine) in cerebrospinal fluid, which surrounds the brain. Denosyl provides SAMe in a stabilized form to help with brain health and act as a neuroprotector.

The new chewable tablets of Denosyl allow dogs to receive SAMe in a tasty treat eliminating the need to "pill" your dog daily. Additionally, the chewable tablets are absorbed more quickly when compared to hard enteric-coated tablets.
