Is Hydrogen water safe?

Hydrogen water is a hoax, firstly the hydrogen doesn't stay in the water and secondly has ZERO peer reviewed benefits, at best it's snake oil.

I can pretty much guarantee that if you open a bottle of so called "Hydrogen Water" next to a naked flame it won't explode or even ignite (Hydrogen (H) turns in to water (H₂O) when it combusts as the hydrogen atom grabs two extra Oxygen atoms in the process, It can not actually be dissolved in water like CO₂ can, you can't suspend H in a mixture of H₂O because H is a gas that does not react with the water in any way.

In fact if you could use a chemical reaction to make the water hold Hydrogen (Like Carbonic Acid in CO₂ which is H₂CO₃) it would form H₃O₂ which they call "Structured Water" or "Living Water" or "Alkaline Water" (three known pseudoscience water scams) but H₃O₂ doesn't actually exist on it's own in nature or science.

There is no difference between So called Hydrogen Water and Bottled Water, even if the product existed it would not have any health benefits as it's neutralised by stomach acid and the gas it excreted would be Hydrogen which is HIGHLY Flammable in an Oxygenated environment, a single spark or hot amber and "Boom".
