TL;DR
Alkaline ionized water (AIW) maintains its bioactivity under stress and has antibacterial effects, unlike tap and purified water.
Key Finding
Alkaline ionized water maintained antioxidant and antithrombotic (blood-clotting prevention) activities better than tap water when exposed to heat and physical stress in laboratory conditions.
Summary
Researchers compared alkaline ionized water (water made more basic through electrical treatment) with regular purified and tap water to see if they could maintain helpful properties like antioxidant activity (protecting against cellular damage) and antibacterial effects (killing harmful bacteria). They found that alkaline ionized water and purified water better preserved these protective properties when heated or shaken, while tap water did not. Alkaline ionized water also showed antibacterial activity against E. coli bacteria in lab tests.
Practical Takeaway
This laboratory study suggests alkaline ionized water may have potential benefits, but important limitations apply: the research was conducted in cells and test tubes rather than in humans, sample sizes were not reported, and the study did not directly test hydrogen water. More human studies would be needed to determine if these laboratory findings translate to real health benefits.
Abstract (excerpt)
In this study, the stable maintenance of bioactivity in alkaline ionized water (AIW) and antibacterial effects of AIW were evaluated to confirm benefits of AIW. As controls, purified water (PW) and tap drinking water (DW) were used. The pH and ORP (oxidation-reduction potential) of AIW, PW and DW…
