Table 2 Characteristic parameters obtained from hydrogen-dissolved water vs. reversed osmotic ultra-pure water

From: Hydrogen water intake via tube-feeding for patients with pressure ulcer and its reconstructive effects on normal human skin cells in vitro

  DH (ppm) DO (ppm) ORP (mV) pH Water temperature (°C)
Hydrogen-dissolved water (HW) 0.80-1.30 6.91 −602 7.40 24.1
Reversed osmotic ultra-pure water (RW) < 0.018 8.26 +184 7.37 24.2
  1. Abbreviations: DH dissolved hydrogen concentration, DO dissolved oxygen concentration, ORP oxidation-reduction potential.
