Denamarin is a liver support supplement for dogs and cats containing S-Adenosylmethionine (SAMe) and silybin. Administering SAMe (S-Adenosylmethionine), which is found in Denamarin, has been shown to markedly increase liver levels of glutathione, an important compound for liver health formed when SAMe is metabolized. The SAMe in Denamarin has also been shown to help protect liver cells from cell death and may help cell repair and regeneration. Denamarin also helps support the liver through the administration of silybin. Silybin is an active part of an extract from milk thistle, known as silymarin, and has been shown to support liver function by helping maintain a healthy oxidative balance. Contains 225 mg of S-Adenosylmethionine and 24 mg of silybin A+B.
