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.
