Here's what the promoters are saying.

"Cell Food" and similar supplements are marketed as a remedy for supposed oxygen deficiency, resulting in all sorts of wondrous health benefits.

The claims are nonsensical (for instance, oxygen levels in the atmosphere have not drastically declined in human history). There's no evidence to support any benefits from "Cell Food" (and its gazillion trace elements, including such exotica as neon and thorium) other than unreliable testimonials.

More on oxygen quackery, which apparently is fairly big business these days.

This may be a rare occurrence, but in this case I agree with Eric. :)

Our bodies bring oxygen to tissues under the tight control of heme groups in the red blood cells. Inside the cell we also tightly control oxygen in mitochondrial energy production with heme groups. When oxygen leaks, damage happens. The term "free radical" is used to refer to out of control oxygen.

If the maker of this product is correct in his claim of bringing oxygen to every cell, then that effect is dangerous because of the corrosive effects that it would have. Rust is an example of what happens to something exposed to oxygen. If they are not correct, it is false advertising. Either way it does not serve the consumer well.
