We did it in a sealed system. No oxygen present.

It did. Simple system of otherwise evacuated glass tubing. Pretty
standard stuff.

Stars burn hydrogen.

Burning hydrogen produces water in the presence of oxygen, as in H2O. No
oxygen, no water produced.

But this isn't the place to discuss this anyway LOL!

True, but common table salt is sodium chloride. In the presence of
water, it dissociates into Na+ and Cl- ions. When someone needs to cut
back on sodium (in certain medical conditions), it doesn't matter from
where the Na+ originates. It can come from table salt or foods
containing relatively large amounts of sodium (such as raw celery or raw
carrots).

If such are, then one could say (like the marketers

You must not live in a desert. It's very easy to consume too much water
And there is such a thing as water intoxication, which is consumption
of too much water.
Too much oxygen is also unhealthy in the long term. You did know the
atmosphere you breathe is about 80 percent nitrogen and 20 percent
oxygen?
