Biological impacts of magnetic water treatment: A mini-review of mechanisms and applications

Magnetised water, produced by exposing water to a magnetic field, has been proposed to offer various health benefits by altering its physicochemical properties. This mini-review explores the biological mechanisms and potential applications of magnetic water treatment in human health. Evidence suggests that magnetisation may modify hydrogen bonding, enhance cellular hydration, influence ion transport, and affect membrane permeability, potentially improving nutrient absorption, detoxification, and anti-inflammatory responses. Limited studies also report benefits in oral health, metabolic regulation, and chronic disease management. However, much of the current evidence is derived from small-scale, methodologically limited studies, and the reported outcomes may be partly attributable to placebo effects. While the concept remains compelling, robust experimental investigations are necessary to validate the clinical efficacy and safety of magnetised water. This review summarises current knowledge, highlights biological plausibility, and outlines the need for further research before magnetic water treatment can be integrated into evidence-based medical practice.
