“Electrolyte-enhanced” bottled water has mineral electrolytes added to purified water . We have frequently observed that electrolyte-enhanced bottled waters of various brands (including “smart” water) have mineral electrolytes at about 20 to 30 ppm (parts per million).

A single drop of EMDROPS in a full 8 oz (~240 mL) cup of purified water provides about 100 ppm of mineral electrolytes (i.e. about 3 to 5 times the concentration of electrolytes found in typical electrolyte-enhanced bottled water), at a far lower cost.
