Marin® for Cats is specially formulated with silybin and vitamin E to provide comprehensive liver support. Silybin is the active ingredient in milk thistle and has been shown to have beneficial effects on liver function. Vitamin E helps protect the liver against oxidant injury. Studies have shown that silybin/silymarin protects against oxidative stress, provides a mechanism for liver cell regeneration, inhibits leukotrienes which are a component of the inflammatory response, and stimulates biliary flow and production of hepatoprotective bile salts. Marin for Cats also increases levels of glutathione, the liver's major detoxifying agent.
