Vitamin O

Liquid oxygen supplements are products that claim to add extra oxygen to the human body, most often through a chemical process in the digestive system, like the breakdown of hydrogen peroxide or magnesium peroxide. While the FDA describes these products as being inert, and has penalized some producers who made explicit medical claims, it has not prohibited their sale.

Liquid Oxygen is the name of a product that is a solution of hydrogen peroxide and other compounds including sodium chloride (common salt) that claims to help with "jet lag, fatigue, altitude sickness, headaches, hangovers, youthful skin, energy, and insomnia".

Professor Ken Harvey, a member of the World Health Organisation team that formulated criteria for the promotion of medicinal drugs and a member of Auspharm Consumer Health Watch, states that the product is "no more than salty water", and that most forms of water carry some dissolved oxygen. The Federal Trade Commission has prosecuted some makers of such products for making "blatantly false and unsubstantiated health claims", although it has not banned the sale of such products.

The product claims to have an effect through increasing the amount of oxygen in the body but this is unnecessary as oxygen is absorbed by the lungs via breathing. Among the ingredients sometimes listed by makers are magnesium peroxide, or "deionized water and sodium chloride [salt]". It cannot contain simple liquid oxygen, which would boil at -297°F at normal pressure, but ostensibly contains oxygen in some other form, like hydrogen peroxide, that will be released after consumption.
