A3:
It is said that 400ppb (0.4ppm) or more is effective in the researcher's books. In the world of 1 atm where we usually live, the saturated state of hydrogen is about 1600 ppb (1.6 ppm), but by compressing the inside of the container, more than saturated hydrogen enters. However, in this case, opening the mouth of the container causes hydrogen to escape at once. Large numbers do not mean dramatic changes. Ideally, silky pure or silky should be electrolyzed just before it is used for drinking or cooking, and used when it contains a large amount of hydrogen. It is recommended to drink a certain amount of hydrogen water every day.
