All I drink is Ionized Water . I really feel a difference drinking it, and won't go back to normal water, and I "treat" water for a living. Look up the "Regency II" water filter. I think they're around $650 now. You can set the ph to 11 which is all I drink and it treats 1000 gallons, which is about what I drink in a year.
I tried magnetic water at a fair one time and it seemed to give me energy, but I haven't invested in one of those yet.
