Are Water 'Ionizers' Worth Buying?

by Berkeley Wellness  

Q: Is there any benefit from drinking alkaline water made by special ionizer machines?

A: Don’t buy the claims made for “ionized” water and ionization machines. Ionization refers to the conversion of an atom or mole­cule into an ion by adding or removing a charged atomic particle. Marketers use the term to promote expensive machines that are supposed to almost miraculously enhance tap water by zapping it with electricity. Promoters say that the machines make drink­ing water more alkaline using a process called electrolysis, which acts on minerals that are already in the water or added to it.

Manufacturers, mostly from Asia, claim that the mildly alkaline water produced by these machines is rich in antioxidants and can prevent or banish a host of ills, including cancer, diabetes, and digestive disorders. But there is no credible evidence that such water can prevent or cure any disease or that it has a significant impact on the acid/alkaline bal­ance of your body. Anything you consume is acidified in the stomach—that would be the end of any alkalization from ionized water.

Even if alkaline water were beneficial, you could make it yourself adding a little baking soda (sodium bicarbonate), for instance, to tap water—no need to spend thousands of dollars on a machine. Actually, if your tap water is hard, it’s already slightly alkaline.
