Hydrogena water Does it have real benefits?

Good, I write here because this morning a man has offered my mother a device to hydrogen the water, saying as an argument the seller that reduces glucose levels in type 1 diabetics, as is my case.
It was to know if someone has tried and works, or if you know any study on this, since only pages that sell these devices on the subject appear.
Greetings and thanks :)

@Macia_mas, it is nothing more than water with gas.From time to time those scams appear, I remember the "magnetized water."Nothing is deception.
