Ionized water has to, obviously, go through the stomach after we drink it.  With hydrochloric acid, or gastric juices in the stomach, my question with this series of experiments was “Which Ionizer will produce more stable, drinkable, thoroughly ionized water?”

You do not drink the highest levels of ionized water. The best pH levels for drinking are between 9.0 and 9.5. The reason for this is that the digestive system will best accept and benefit from ionized water in this narrow range. In the following experiments I took the water ionizers which produce the best, most efficiently ionized water at pH level 9.5 and simulated what would happen to that water in the process of passing through the stomach and entering the upper intestines [where a pH most desirable for this section of intestine is 8.8].

The way I conducted this experiment, was to measure the pH and ORP at level 3 (for the Enagic it is called “Kangen water 9.5”) of each of these water ionizers.  Then I added drops of vinegar to the ionized water [to simulate the water passing through the stomach and lightly coming into contact with stomach acid]. My goal with the experiment was to see which ionizer could come as close to the 8.8 pH value that is ideal for the upper intestines while at the same time maintaining a high negative ORP [anti-oxidant] value.

On the first chart below you can see I started out with one drop of vinegar added.  After that I added two more drops (see second chart).

Analysis and Conclusions

Enagic Water Ionizer: The Enagic water ionizer was tricky to work with because it wanted to produce stronger levels of pH than I felt was good for a person to consume.  However, whenever I produced lower, more acceptable drinking levels of pH with the Enagic water ionizer, it was also accompanied by what I felt was too low of a strength of water ionization (ie., the ORP was too weak).  When using those weak settings, the results of adding drops of vinegar were very poor.  The only time I could get decent results with the Enagic water ionizer was when I used a slower flow rate.  The problem with this was the pH came out so high that in my opinion the ionized water was too high for drinking.

Tyent Water Ionizer: The Tyent water ionizer had excellent results when I added one drop of apple cider vinegar.  However, by the time it had been sitting there for a few minutes, the ORP was showing signs of instability.  When I added two more drops of vinegar, it went to a very low ORP.

Athena Water Ionizer: The Athena water ionizer had excellent results.  It retained its excellent ORP even after adding the two extra drops of vinegar.

It’s difficult to draw conclusions from one test, but I have to say that I am once again very pleased with the result of the Athena water ionizer.  I will definitely be doing more testing in the future though as I really was expecting the Enagic and the Tyent water ionizers to do better in this water ionizer comparison test.
