As always we encourage everyone to be an informed consumer and we are passionate to educate all who walk through our door about our natural alkaline water and its many health benefits. So maybe you are wondering what is ORP? ORP stands for Oxidization Reduction Potential. We do not see it, but there is a continuous exchange of electrons that takes place between substances in the air, in the earth, in water, and in our bodies. This is known as ion exchange. A positive (+) ORP ...reading indicates that a substance is an oxidizing agent. The higher the reading, the more oxidizing it is. A negative (-) ORP reading indicates that a substance is a reducing agent. The lower the reading, the more anti-oxidizing it is. Alkaline water is an anti-oxidizing agent, as it has a negative ORP value and it is able to donate extra electrons to neutralize the harmful effects of free radicals on the body.
