Yes! A number of doctors and health professionals have conducted a variety of tests to verify the effectiveness of hexagonal water produced in the Vitalizer Plus. Recent testing performed by Shelton Educational Services in Phoenix, AZ, showed that one glass of vitalized water improved Heart Rate Variability (HRV) scores by an average of 29.4% - in just 10 minutes. Similar testing showed that point scores using Meridian Stress Analysis (MSA) also improved significantly (24.7%), in the same 10-minute period of time. Other methods, including live blood analysis, body composition analysis, and Kirlian photography show marked improvement after drinking vitalized water.
