The components in the Juvenon formula have been shown to improve both mental and physical activity in experimental animals. There is also experimental evidence (both in vivo and in vitro) that the supplement’s components aid in tissue protection by suppressing the generation of tissue-damaging free radicals. Skeletal muscle, the heart, the liver, and nervous system tissue are among the tissues that are protected. The vast majority of these investigations used dogs and rats. Cats, unlike dogs and many other animals, are unable to tolerate the Juvenon product because they are allergic to one of the active ingredients, alpha lipoic acid. The cat’s liver’s metabolism of lipoic acid differs greatly from that of other species, resulting in liver damage. As a result, Juvenon is not suggested for cats, although it may be taken by dogs and rodents.
