Kangen water is a brand of electrolyzed reduced water, aka ERW, that is created from your own kitchen sink!
ERW is living, structured, hydrogen-rich water that is created via electrolysis. It starts off by filtering your tap water (getting rid of many of the contaminants while keeping the naturally occurring minerals) and then continues on to ionize your water. This ionization creates alkalized water that is structured & antioxidant-rich due to its high concentration of diatomic molecular hydrogen!
