Water: Negative ORP vs Positive ORP

In recent years, scientists have done a lot of research on the characteristics of the second most basic essential for life—water. Needless to say, now we have insights into factors that can help us make the most of the water we drink and use it to
keep our bodies healthy and our organs clean. One such factor is Oxidation-Reduction Potential (ORP).

Understanding the fundamentals behind the nature of water

Fundamentally speaking, water can have a moderate Oxidizing characteristic (such as aerated water), strong Oxidizing characteristic (chlorinated water is a good example of that), or a reducing characteristic (that can create environments where anaerobic microbes are prevalent).

The difference between Oxidation and Reduction

Just like pH value indicates a water sample’s state to gain/lose protons, ORP determines a water sample’s state to gain/lose electrons. Oxidation occurs upon the removal of electrons. When free radicals take electrons from cells, the cells; oxidation states; increases. On the other hand, a reduction occurs when a factor—like an antioxidant—gives electrons to a free radical, thus decreasing the free radical’s oxidation state. As such, antioxidants also help your body keep cells safe from free radicals.

What ORP values indicate

As such, the higher the ORP value, the more “oxidization” will happen (due to the water molecules’ability to share electrons), and vice-versa. Measured using the unit millivolts (mV), ORP determines the amount of dissolved oxygen present in a water sample. If the ORP value is negative, the sample has a higher reductive potential. If it’s positive, it has a higher oxidative potential.

What does Positive ORP indicate

The higher the ORP level or oxidation potential, the higher the water’s ability to steal electrons from the DNA, damage cell membranes, and break down protein.

Why water with Positive ORP is dangerous

Our body has an internal environment that is reductive, and for water with a positive ORP to become “compatible” with us, it will have to steal electrical energy from cell membranes. This is what makes it dangerous for consumption.

What does Negative ORP indicate

While a positive ORP value indicates the oxidation potential of water, a negative ORP value indicates the reductive potential. In laymen’s terms, reductive potential, or a negative ORP is nothing but the reduction of the oxidation capacity of water.

Why water with a Negative ORP is good for you

Just like chlorine is added to drinking water in order to kill the microorganisms present in it (by oxidation), certain things like vitamin C and molecular hydrogen can also be added to water to achieve a negative ORP. Additionally, these elements have physiological benefits for the human body.


As mentioned earlier, a healthy person’s internal environment has an ORP that is reductive. This combined with the fact that vitamin C and molecular hydrogen are added to the water, making negative ORP a beautiful option for health. Water that has such ‘antioxidants’ helps the body protect cells from an onslaught of free radicals that can steal electrons, damage DNA, affecting your overall health. So, consuming Negative ORP Water is one of the natural options to fight this internal damage and live longer.
