The current data shows that there is no such thing for the time being, but we need to read the materials clearly. There are mainly magnetized cups, composite mineral materials, tourmaline, medical stone and so on.

For example, the magnetized cup should not be used by people with physiological disorders, which will interfere with the human biological clock;

Compound minerals can't be used by people with hypochlorhydria, because its water is weakly alkaline, and its molecular group is small, which is easy to neutralize gastric acid.

Tomalin, people with hypochlorhydria can't use it. Its water is alkaline.

Medical stone, so far no relevant data have been found.
