Our scientists, veterinarians and formulators began with the premise that most pet diets are lacking the proper amounts of vitamins, minerals and antioxidants. There are important nutrients that animals once received when they were living in a more primitive environment that are not available in the modern diet. Commercial pet foods contain numerous by-products that can make them poisonous, toxic and incapable of reducing the devastating effects of unstable oxygen molecules, also known as "free radicals." Free radicals have been implicated in more than fifty health problems in humans and animals including various forms of cancer, heart disease, arthritis, cataracts and premature aging.
