We evaluated the properties and real existence of an electrolyzed-reduced water, which we prepared, and
three commercially purchased water goods, that are advertised to have antioxidant activities by the action of
"active hydrogen," on the basis of the results of examinations for inhibitory effects on the oxidative reactions of
biomolecules, quantitative analyses of the minerals, and the ESR spectral data in measurement of the scavenging
ability for reactive oxygen species. The results suggested that all of the examined aqueous solution systems
undoubtedly have antioxidant activities in
vitro and that such effects are derived from ordinary molecular
hydrogen (hydrogen gas) and/or (a) reductive vanadium ion(s). "Active hydrogen" seems to be absent as an effective
component of the antioxidant activities of these aqueous solution systems.
