Silica Hydride


Silica hydride is a mineral. It has been used as an antioxidant to help slow damage to cells. Silica hydride has not yet been tested on humans or animals. It can be taken as a pill or powder, but it is not widely available.


There are no advised doses for silica hydride.

What Research Shows

There is not enough data to support that silica hydride is helpful in treating health problems. We will review future studies as they are published.

Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.

Safety Notes

Not enough studies have been done to say whether it is safe to take silica hydride.


Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
