Water ionizers - Jupiter DelphiAlkaline water, also known as ionized water, differs from the normal water by its pH level. While normal water has a pH of 7 (which means neutral), alkaline water has a pH of almost 8. The pH scale is the measure for acidity or alkalinity of solutions. It ranges from pH 0 to 14, solutions with pH 7 being neutral, pH > 7 alkaline and pH < 7 acidic.

In order for the normal water to become alkaline, it has to go through a process of electrolysis.

This article is an overview on all information I found on alkaline water benefits and water ionizer systems. It is only a starting point for discussions, so if you have any experience to share with us regarding ionized water and what it did good or bad for you, please use the comments section below.

Alkaline Water Benefits

While there are scientifically proven benefits to drinking water, there’s no proven medical evidence in stating alkaline water is superior to normal water. Nonetheless, many people claim alkaline water is good for health, some of them speaking from their own experience. I remember reading in a discussion forum that somebody said alkaline water helped her with her asthma condition. Maybe it did, or maybe it was only the placebo effect, we have no way of knowing that.

One of the most often used arguments in favor of ionized water is that many foods are acidic, therefore upsetting the pH balance of the body. Since the method of neutralizing an acid solution is to add a base, alkaline water is thought to help balancing the body, thus leading to a state of well-being. I didn’t find any research to support this. However, if you want to read more about alkalinity and the acidic diet, and to get a list of alkaline and acid foods, you can download this free report. The report comes with an optional bonus, a free consultation with a water specialist with whom you can discuss your water issues. I think it’s worth taking a look into it.

Back to the benefits of ionized water, here’s what I found:

Alkaline electrolyzed water assists in the alleviation of gastrointestinal disorders, acidosis, chronic diarrhea, and poor digestion. This claim appears to be endorsed by the Japanese Ministry of Health and Welfare. Source:

Antioxidant properties: antioxidants strengthen the immune system. They neutralize free radicals which are the cause of cell damage. Vitamins E, C and A are among the most-known antioxidants and they’ve been proven effective by research. As of the antioxidant properties of ionized water, here’s a quote from the previously mentioned source:

Recent research in Japan has shown that electrolyzed alkaline drinking water has a synergistic effect on antioxidants. For example, the antioxidant strength of vitamin C in electrolyzed alkaline water is several times greater than vitamin C in tap water. The synergistic effect is due to the higher dissociation/ionization constant of the functional (electrolyzed) water.

The previously mentioned website lists references, thus being much more credible than other sources. Here’s the reference for the above quote: Hanaoka, K.; Antioxidant Effects of Reduced Water Produced by Electrolysis of Sodium Chloride Solutions, (to be published in J Applied Electrochemistry, 2001).

Shirahata, S., et al: Electrolyzed-Reduced Water Scavenges Active Oxygen Species and Protect DNA from Oxidative Damage, Biochem. Biophys. Res. Comm. 234 (1997) 269 is a study supporting the claim that ionized water enhances the immune system and inhibits autoimmune disease. Mice given electrolyzed alkaline water lived 30% longer. I found no research on humans, however, on the antioxidant properties of alkaline water.

Management of metabolic acidosis. Metabolic acidosis is a result of endogenous acids accumulation in the body or of kidneys failure of eliminating the acids. It is a very severe and possibly lethal condition. I found this study published by Department of Urology, El Mansoura Urology and Nephrology Center, Mansoura University in Egypt, regarding the use of ionized alkaline water as a strategy for the management of metabolic acidosis. The study was done on dog and rats and it showed significant improvement. The conclusion was that alkaline ionized water can be considered as a major safe strategy in the management of metabolic acidosis secondary to renal failure or dialysis or urinary diversion. Studies on humans are yet to be done.

This sounds promising, but I’m not sure how it translates for the average, healthy individual who isn’t sure whether or not ionized alkaline water provides real benefits for him and his family.

Water Ionizer Systems

Water ionizers for home use connect directly to the faucet and they usually play a double role: filter and ionizer. They come with installation kits and instructions, so anyone with basic DIY skills can install one without needing a plumber. Maintenance of water ionizers is simple, as they have a self-cleaning feature. The only thing you need to do is replace the filter. If you live in an area with hard water, you may also need descaling every 1-2 years. You can use a vinegar solution to do that.

There are several manufacturers of water ionizers such as Ionways (former Jupiter), Tyent, Enagic (Kangen), Life Ionizers or KYK. I’m not going into details about their devices, but here’s a comparative table of the most popular water ionizers.
