Note: This review does not cover vitamin O that contains germanium. Please see the individual monograph on germanium for more information.
Oxygen is an integral part of human existence. Some have dubbed this element as "vitamin O," even though it is not a true vitamin. Proponents of vitamin O claim that disease occurs because the body is lacking in oxygen. Therefore, by ingesting oxygen through vitamin O supplements, these ailments can be reversed.
There appears to be two types of vitamin O products on the market. The first is an expensive health supplement that is composed largely of salt water and "stabilized" or "aerobic" oxygen. Companies, such as RGarden, marketed vitamin O (without germanium) claiming that it could cure or prevent serious diseases such as cancer, heart disease, and lung disease and when taken by mouth, enrich the bloodstream with supplemental oxygen. These claims were never substantiated with scientific evidence; however, numerous testimonials mention the effects of vitamin O on a variety of conditions. The second vitamin O product contains germanium, which when synthetically derived may be nontoxic and safe at high doses.
There is no scientific evidence currently available regarding the effectiveness of vitamin O or the benefit of ingesting stabilized or aerobic oxygen. Vitamin O (oral or topical oxygen) has not been proven to be an effective treatment for its claimed uses.
There is no proven safe or effective dose for vitamin O in adults.
There is no proven safe or effective dose for vitamin O in children.
