The BION Institute for Bioelectromagnetics and New Biology in Ljubljana, Slovenia, has conducted a scientific study on BioAq water. The tests were performed on different occasions with BioAq water and control water and the subjects’ physiological response was measured. The study was conducted to test the impact of energy on humans. The aim was to investigate an objective subtle field impact of BioAq structured water on humans. The testing was prospective and randomized. Placebo effect was excluded, the test subjects did not know which water they were drinking. The examination was also double-blind, not even the test assistant knew what water was provided to each test subject. Different physiological parameters were measured in test situations when the test subjects had either drunk BioAq water or control water. To measure the parameters, a Biosignalplux device was used. To investigate differences, Wilcoxon test was used, and for more comparisons, Holm-Bonferroni correction was used. The results showed several statistically significant differences in the consumption of BioAq water and control water. It showed that BioAq water has an energizing effect on humans.
