Are There Real Health Benefits from Drinking Ionized Water-

　　Are there any discernible health benefits to drinking ionized water? The phrase "ionized water" itself carries little substantial meaning. Water does contain dissolved ions, which are essentially particles with an electrical charge. Nonetheless, ionized water merely indicates water that has mineral ions, a result of minerals either gaining or losing electrons. Nearly all natural water sources acquire ions such as calcium and bicarbonate following contact with rocks and sediments. Even the purest rainwater absorbs hydrogen and bicarbonate ions from atmospheric carbon dioxide. Essentially, pure water is composed mainly of H2O molecules in a relaxed, dynamic network. Although these molecules tend to slightly separate into hydrogen and hydroxide ions (H2O ? H+ + OH-), this occurrence is negligible, and the reverse reaction is far more rapid. Consequently, only approximately two out of every billion molecules are separated, making pure water practically ion-free and non-conductive.

　　Both acidic and alkaline waters, as well as all aqueous solutions, include H+ and OH- ions. Acidic water possesses a higher concentration of H+ ions compared to OH-, whereas alkaline water has the reverse scenario. Neutral water contains an equal amount of each ion, with a pH level of 7 on a scale ranging from 0 to 14. Each pH unit denotes a hundredfold change in the ratio of ions. Alkaline water has excess OH- ions and thus necessitates additional positive ions, often metal ions like sodium or magnesium, to balance the charges. Conversely, acidic water has surplus negative ions, such as bicarbonate. Waters with a pH other than 7 are not chemically pure.

　　"Ionized water" is a product promoted by the alternative health sector, frequently targeting individuals without a scientific foundation. Many of these costly devices claim to generate "ionized" and alkaline water through electrolysis. The truth is that "ionized water" is a marketing term devoid of scientific merit. All natural water contains some ions, and most drinking water does not conduct electricity sufficiently for significant electrolysis. Pure water cannot be alkaline or acidic, and electrolysis cannot alter this. While groundwater with metal ions can become slightly alkaline, this is neutralized when it encounters stomach acid. The idea of needing alkaline water to counteract acidic foods is baseless, as the body eliminates excess acids through carbon dioxide. There is no credible scientific evidence supporting the health advantages of alkaline water. Slightly acidic water, akin to rainwater, is safe for consumption, and the concept of "body pH" is irrelevant, as different body parts have varying pH levels.

　　If the goal is to decrease stomach acidity, there is no need to invest in electrolysis devices when calcium-magnesium supplements or over-the-counter antacids are readily available. These devices are generally ineffective for improving health, removing impurities, disinfecting, or controlling scale. In the end, it is wiser to keep your money rather than investing in so-called ‘ionized water’.
