Concentrations of H2 in the super-saturated H2-rich water prepared by Method II. a Concentrations of H2 measured at 10, 15, and 25 C after 10 min and 24 h (###p < 0.001, 10 min vs. 24 h at the same temperature; **p < 0.01, 10 C vs. 15 C after 10 min, or 10 C vs. 25 C after 10 min). b Concentrations of H2 measured immediately after 24 h, and then measured 1 or 2 h after the cap had been opened (***p < 0.001, Immediate vs. 1 h, 1 h vs. 2 h, or Immediate vs. 2 h). c Concentrations of H2 measured after 1 or 7 days without opening. Data are presented as mean ± standard deviation (SD) for 3–5 independent measurements
