Structured water, sometimes called magnetized or hexagonal water, refers to water with a structure that’s been altered to form a hexagonal cluster. This cluster of water molecules is believed to share similarities with water that hasn’t been polluted or contaminated by human processes. The theory behind structured water suggests these qualities make it healthier than tap or filtered water. According to structured water proponents, this type of water exists naturally in mountain springs, glacier melt, and other untouched sources.
