Deionized water, sodium chloride, and magnesium peroxide are the most common ingredients in liquid oxygen drops, but formulas vary depending on the manufacturer. Users claim that liquid oxygen drops treat a myriad conditions ranging from obesity to arthritis, states WebMD. The U.S. Federal Trade Commission maintains that they are just ordinary salt water.
Makers of the drops claim the release oxygen within the body, but there is limited empirical evidence to back this assertion or to support any claims of efficacy in treating any condition, says WebMD. Additionally, as of 2015 the medical community has not thoroughly tested the products, so there are no established dosages. These products are not really liquid oxygen.; oxygen exists in liquid form only at temperatures well below freezing. The drops are also not vitamins, despite sometimes being called vitamin O.
