What is the purpose of oxygen pills?

Oxygen pills may provide increased energy, boosts to the immune system, relief from mental health disorders and improved lung function, explains WebMD. Despite widespread use of oxygen pills and the large list of their supposed benefits, the Federal Trade Commission has found that the pills consist only of salt water.

Oxygen pills, also known as Vitamin O, do not have approval for treating or curing any disease or disorder, according to WebMD. This supplement claims to contain oxygen-releasing ingredients that provide a number of health benefits. Neither the claims nor the specific ingredients in oxygen pills have any scientific credibility.
