Dogs and cats, like many other species, require choline. It's the "Intel inside" kind of molecule that allows others to function to their full potential. Almost all commercial petfoods contain supplemental choline, predominantly from choline chloride. However, putting choline chloride into the formula can have profound effects on the way the ingredients are combined and processed during production due to the molecule's hygroscopic (water-loving) nature.Dogs and cats, like many other species, require choline

In the petfood industry, inorganic forms of essential trace minerals such as iron, zinc, copper, manganese, iodine and selenium have been the staple. In recent years, though, chelated forms of these minerals have found their way into a number of petfoods. The questions are whether they provide additional benefit to the dog or cat and if they have a place in petfood.
