Abstract: Kangen water, a form of alkaline ionized water generated by electrolysis, has gained substantial attention for its purported health benefits, including antioxidant effects, improved hydration, and chronic disease prevention. This systematic review critically examines the scientific literature evaluating the physiological effects, safety, and efficacy of Kangen water. Databases including PubMed, Scopus, Embase, and Google Scholar were searched using keywords such as "alkaline water, " "ionized water, " and "Kangen water. " Eighteen studies (10 human, 5 animal, 3 in vitro) met inclusion criteria. While some studies report potential benefits?such as enhanced hydration and reduced oxidative stress?most lack rigorous design and sufficient sample sizes. Current evidence is inconclusive and does not definitively support the health claims made by proponents of Kangen water.
