Doctors recommend that you drink at least eight glasses of water everyday, but what many doctors fail to mention is the quality of those 64 ounces. Most tap water is chlorinated for sanitation purposes, but while chlorine is killing the disease-causing bacteria, the friendly bacteria in our bodies are also dying.
