Health and Wisdom Pure Magnesium Prills are made of magnesium oxide produced from underground magnesium salts. These prill beads undergo high-temperature kiln firing and an energy-charging process, turning them into water-insoluble, ceramic-like pellets. They are designed to create structured water for drinking, which is thinner and provides enhanced hydration. The prill beads also help in removing heavy metals from water. They can be used repeatedly without dissolving, making them a cost-effective solution for cleaner and softer laundry with less detergent residue.
