Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what effects silica has on your body, and how strong these effects are.

Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.

1Sources and Structure

1.1. Sources

Silica, synonymous with silicon dioxide,

1.2. Biological Significance

Silica is normally found in water as a free-floating mineral, and is said to be particularly abundant in glacial streams. Rather than existing as a stand-alone ion, silica tends to form various 'colloidal minerals' where silicon dioxide binds together and attracts water; this configuration sometimes traps other minerals such as Potassium, Magnesium, and free hydrogen ions within the silica colloids found in some water supplies.

It is claimed[1] that some long-living populations (Hunza, Pakistan) may partially credit their longevity to high silica levels in their water supply, which may hold basis as high silica concentrations in drinking water tend to ameliorate the negative effects of too much aluminum in the water when it comes to the elderly.[2]

1.3. Formulations and Variants

Silica Hydride refers to a polymeric colloid which is composed of silica, and contains numerous H- ions.[3]


2Skeletal Muscle and Physical Performance

2.1. Aerobic Cardiovascular Health

When six trained male cyclists were given either silica (as colloidal silicate) in three divided doses totalling 1g, for one week before a 40km bike ride, found that the group supplementing silica did not have any significant differences in heart rate, VO2 averages, workload averages or rate of perceived exertion; there was, however, less blood lactate produced in the supplement group compared to placebo.[1]


3Interactions with Aesthetics

3.1. Skin

When tested in vitro (not skin cells, but rather CHO and NS-1), silica hydride appeared to protect the cells from light-induced damage claimed to be due to antioxidant properties.[3]
