Alkaline Water v.s Ionized Water

infographic difference between ionized water and alkaline water

The main difference between alkaline water and ionized water is that ionized water can be either alkaline or acidic

Chemistry of Ionized Water and Alkaline Water

Alkalinity measures the ability of alkaline water to neutralize acids. Alkaline water can have high alkalinity while having only a moderately alkaline pH because alkalinity and pH are not the same thing.

The Potential Hydrogen (pH) of alkaline water refers to its potential to attract positively-charged Hydrogen ions (H+).  pH isn’t as important as alkalinity when it comes to your health. What you’re drinking alkaline water for is it’s alkalinity and it’s antioxidant potential. Both of these healthy qualities of alkaline water are enhanced when alkaline water is ionized with a water ionizer.

Ionization occurs when an atom or molecule either gains or loses electrons, when that happens, the atom becomes an ion.  When an atom becomes an ion, it also gains an electrical charge. The charge can be either positive or negative depending on whether the atom gained or lost electrons. Ionized alkaline water is water that has had its pH increased by ionizing the minerals in it. Those minerals, mostly calcium, magnesium, and potassium, gain extra electrons when water is ionized by a water ionizer. The extra electrons give the alkaline water a negative electrical charge, which is what gives the water it’s antioxidant potential.

The difference between alkaline ionized water and ionized water is:  Ionized water can be either alkaline or acidic.  Alkaline ionized water has alkaline minerals in it, and acidic ionized water from a water ionizer has carbonate in it, which makes it a dilute solution of carbonic acid.

Oxidation Reduction Potential – The benefit of alkaline water from a water ionizer

A water ionizer puts a negative electrical charge into the alkaline water it makes. That negative electrical charge gives alkaline water antioxidant potential which can be measured, just like the charge of a battery. The negative charge of ionized alkaline water  is called its Oxidation Reduction Potential (ORP). In-vitro (in the lab) studies have shown that water with a high negative ORP, when mixed with a proton-donor such as vitamin C gains an enhanced antioxidant effect. The only  problem with the antioxidant potential of alkaline water is, you can’t store it for very long. The antioxidant ORP of alkaline water begins to decline after about 24 hours

Why Bottled Alkaline Water has no Antioxidant Potential, but can have toxic antimony in it

Bottled alkaline water has no antioxidant potential because the antioxidant potential of alkaline water can’t be stored in a bottle. Because of this, the alkaline water you buy at the store doesn’t have antioxidant potential like the water you drink fresh from a water ionizer. There is another problem with bottled alkaline water as well – BPA and antimony contamination. Bisphenol A is a potent hormone disruptor and potential carcinogen. Antimony is a heavy metal and a known carcinogen. Alkaline water actually draws antimony out of plastic, so the antimony contamination will be worse with bottled alkaline water than it is for plain bottled water.

You can finance a water ionizer for less than you’d pay for bottled alkaline water Bottled alkaline water is expensive, you will pay between $2 – $5 per bottle for it. If you drank 2 liters per day of bottled alkaline water, you’d easily spend more than $100 per month! You can finance a water ionizer for about half that, and have it paid off within two years.

Triple the Antioxidant Potential of Vitamin C with Ionized Alkaline Water

A study called Electrolyzed-reduced water protects against oxidative damage to DNA, RNA, and protein tested the effect of mixing ionized alkaline water with Vitamin C. The result was that ionized alkaline water tripled the antioxidant strength of Vitamin C. It’s easy to get this added antioxidant benefit with a water ionizer. Simply mix the juice of a lemon, lime, orange or any citrus fruit with alkaline water from a water ionizer and drink immediately.
