ORP and pH, and what they mean

Drinking water should have a negative ORP measurement.

  • The value of ORP quantifies the amount of energy in water by numbering electrons. It means how strong the antioxidant content is, and with that the capacity to reduce free radicals or to reduce oxidation.
  • ORP values are expressed as millivolts, or mV.
  • Drinking water should have a negative mV number of at least -50mV. Ideally as a regular drinking level it should offer -200 to -300mV.
  • Water with an ORP of -50mV already has negative ions and can attract and neutralise excess acidity. When the charge is significantly higher such as -300mV which is usally delivered with ionised water at a level of approx pH9.5), then the capacity to detox and neuttralise acidity is greatly increased.

About pH and ORP


Drinking water should have a pH level at or above 9.5.

pH is the measure of the acidity or alkalinity of a solution. First introduced by Danish chemist S. P. L. Sørensen in 1909, pH stands for "power of hydrogen."

  • Pure water at 25 °C has an equal concentration of dissolved hydrogen ions (H+) and hydroxide ions (OH-) and is considered "neutral."
  • pH measures the concentration of hydrogen and hydroxide ions on a scale from 0 to 14, with 7.0 considered neutral.
  • Solutions with a pH level below 7.0 are acids.
  • Solutions with a pH level above 7 are bases (alkaline).


The healthy human body contains both acids and bases. The organs maintain the pH of arterial blood between 7.35 and 7.45. To counteract the amount of acids consumed by eating, drinking, and breathing, the body will take alkaline substances from body parts, such as bone. By drinking alkaline water, you are able to counteract the intake of acids and help the body regulate its pH in a more healthy way. Further it assists the body to detox, and eliminate acidity.
