It can only help your pet be healthier. Articles abound on the role of antioxidants in preventing disease and slowing the aging process. Many of my holistic colleagues agree that antioxidants are beneficial to your pets health. Free radicals are produced naturally in the body in the process of metabolizing nutrients. We unfortunately have in our world today all of those additional environmental elements that contribute to the formation of free radicals.
Chlorinated water is a source of free radicals.
I do not recommend giving tap water to your pets. Ideally, a water filtration system capable of removing chlorine, lead, nitrates, cryptosporidium, giardia, E. coli, salmonella and cholera as a minimum requirement is necessary. Many systems are available so inquire about the kind and type of filter utilized and what substances it specifically removes. Fo od additives and preservatives permeate our food sources. I looked in the pet food aisle of a chain supermarket recently.
