Clinical TrialHighlightedPeripheral endothelial function can be improved by daily consumption of water containing over 7 ppm of dissolved hydrogen: A randomized controlled trialMHID-0038979PMID: 324700222020PLoS ONEToru Ishibashi, Kosuke Kawamoto, Kasumi Matsuno, Genki Ishihara, Takamichi Baba, Nobuaki KomoriBackground: Measurement of the reactive hyperemia index (RHI) using peripheral arterial tonometry (PAT) has shown benefits in the evaluation of vascular endothelial function and prediction of cardiovascular disease prognosis. Thus, it is important to examine the factors that promote the RHI. In this study, we aimed to investigate the effect of molecular hydrogen (H2) on reactive hyperemia-PAT of t
