Experiments and shared thoughts with hydrogen water

I am trying to get a grip on hydrogen water. The 1.6 ml tiny quantities and the hype.
Last weekend I experimented with an ORP meter, PH drops, my hydrogen gas generator and 1/2 liter test bottles.

The water from the faucet has +150 and a ph of 6.5. light yellow.
Our drinking water right out of the 25 liter bottles has an ORP of +200 and a PH of 6.5 light yellow

I immersed the air-stone bubbler into the water for 5 sec. The ORP went down to zero.
Bubbling another 10 seconds and the ORP was around -300. Fully saturated after 10 min the ORP was around -500

Then I bubbled the light yellow PH solution. After a couple of minutes the water turned green then ended light blue. PH of 8.
We did not see any further increment in the PH. After continued 30 minute bubbling, the water was still light blue.
After 24 hours the water was again light yellow. Again CO2 took over the water.
10 minutes bubbling and it was blue again.

The CO2 and thus acidic nature of every available water source seems to be the problem.
Why is hydrogen water so good for us? 1.4 mg? Really?
This immediate ORP change to -300 and the replacing of the CO2 with hydrogen making the water light alkaline and thus more digestible?

Any hydrogen in drinking water and ORP is by definition negative and the removal of the CO2 makes really good tasting and easy digestible water. It dissolves in the throat while normal water hits the stomach.

We work with borderline cases around PH 7. Really alkaline water will not re-carbonate?.
Does alkaline water has an affinity towards acidic regions of the body?
We know alkalinity and h2 water are two separate issues.
Hydrogen just appears to raise the PH of water by removing the CO2. Nothing else. Plus adding ~1.5 ppm in dissolved state.

So what is it that this h2 water does better then inhaling the gas.
It's alkaline with a shiny PH of 8.

It is one of the dosing enigmas that H2 from drinking H2-rich water can sometimes be more effective than inhalation of H2 gas (e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3407490/).

From inhalation, you may not have the same effect on induction of gastric ghrelin secretion, or on the intestinal micro biome, or on the liver, and also the exposure time is also different, all of which may be responsible for these types of observations. Indeed, H2 from water can certainly do things that H2 from inhalation does not, and vice versa (e.g. https://link.springer.com/article/10.1007/s11010-015-2353-y).

Hydrogen water is the best method for all liquid environment inner organ application, specific all gastric and colon related inflammations.
The conclusion is to combine drinking and inhalation. Long term everything get's easier. Testimonials and scientific studies agree.
