Does anyone know much about the ionized water systems? A good friend of mine, who is a dentist, recently purchased the Kangen ionized water system, and claims that drinking the Kangen magic water has changed his life, and given him miraculous health! Is there any truth to the claims that drinking ionized water, especially the Kangen, which claims to be the best, will cure many kinds of illnesses and physical problems, and give you new vitality and energy? Any knowledgable scientists out there? What do you have to say?
