Silica hydride is a colloidal mineral compound containing silicon, oxygen, and hydrogen. According to the developers of this supplement, silica hydride contains a large number of loosely bound electrons that are available to help neutralize potentially dangerous free radicals.1 2 Test tube studies have demonstrated that silica hydride does neutralize free radicals and preserves the health of cells exposed to these radicals. However, whether silica hydride can be absorbed from the gastrointestinal tract and whether it will affect the health of animals or humans has not been adequately tested.
A preliminary study attempted to measure health-promoting properties of silica hydride with a computerized analysis of blood, urine, and saliva samples called Biological Terrain Assessment (BTA). BTA testing indicated some potentially positive effects of silica hydride in healthy people, but no effects in people with diagnosed health problems.3 BTA has not been proven to be a reliable method for evaluating health or disease,4 so even this marginally promising report should be regarded tentatively.
Another claim made is that the electrons in silica hydride can help promote the body’s production of the energy-containing substance adenosine triphosphate (ATP). While test tube studies have demonstrated that some preliminary steps in energy production are facilitated by silica hydride,5 no evidence exists that this will increase ATP production in the body.
Since silica hydride is not essential, a recommended intake has not been established. Whether it is present in food or water is unknown. Supplements contain 200 to 250 mg per capsule.
Silica hydride is not an essential nutrient, so no deficiencies are possible.
Since silica hydride is not essential, a recommended intake has not been established. Whether it is present in food or water is unknown. Supplements contain 200 to 250 mg per capsule.
Due to the lack of published scientific research on silica hydride in animals or humans, side effects and interactions are unknown.
At the time of writing, there were no well-known drug interactions with silica hydride.
