Concentrations of H2 in the super-saturated H2-rich water prepared by Method I. a Concentrations of H2 measured at 10, 15, and 25 °C after 12 and 24 h (###p < 0.001, 12 h vs. 24 h at the same temperature; ***p < 0.001, 10 °C vs. 15 °C after 12 h, 15 °C vs. 25 °C after 12 h, or 10 °C vs. 25 °C after 12 h; **p < 0.01, 10 °C vs. 25 °C after 24 h). 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. 2 h; **p < 0.01, Immediate vs. 1 h; *p < 0.05, 1 h 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
