66% of US tap water is fluoridated.. the best water to drink is distilled water .. can be bought bottled or made at home with a distiller .. paul bragg (a king of heath) who drank his water distilled was active hiking, biking, and climbing well into his 90’s. A very healthy water is distilled water .. please see what you can do to get this fluoride away from our drinking water .. carbon filters don’t filter out fluoride
