The compounds in the Juvenon formula have been demonstrated to have positive effects on both mental and physical activities in laboratory animals. There is also experimental evidence (both in vivo and in vitro) indicating that the compounds in the supplement help to protect tissues by inhibiting the production of tissue-damaging free-radicals. The tissues protected include skeletal muscle, heart, liver, and tissue comprising the nervous system. The majority of these studies were with dogs and rodents. Unlike dogs and many other animals, cats cannot tolerate the Juvenon product because they are sensitive to one of the active compounds, alpha lipoic acid. The metabolism of lipoic acid by the liver of the cat is very different from other animals, and results in liver toxicity. Therefore, Juvenon is not recommended for cats.Recommended dose: 1 tablet/ 50 lb/day or ¼ tablet/12 lbs/day. This dose can be applied to dogs, hamsters and other rodents, and horses.
