I looked at a couple of stabilized oxygen websites, and I must say that it looks like quackery to me.

To begin with, unless you are gasping for air, your body is not short of oxygen. Gasping is the natural reflex your body automatically does whenever oxygen is in short supply. So if you're not gasping, you've got all you need - adding more won't help anything.

Secondly, this stuff is swallowed - taken into the digestive system. Any pill, or treated water, or anything that purports to increase oxygen in your blood via your digestive system is probably wrong. The membranes of the stomach and intestines are very poorly suited to absorbing oxygen. Oxygen will mostly just pass out of the gut as burps or gas. (Lungs on the other hand are very efficient at absorbing oxgen - any oxgen-increasing treatment that is aimed at the stomach is aimed at the wrong organ).

Finally, for this or any other product, you should be very suspicious of stuff that relies on mere testimonials rather than legitimate clinical trials. And you should be doubly suspicious of any product that claims to help or cure a long list of ailments. Both of these are the marks of quack cures. A true wonder drug, like say aspirin, might help with perhaps three different problems. Drugs that are claimed to cure ten or twenty different things always turn out to be frauds.
