Silicon is a trace mineral.

What Are Star Ratings?

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.

2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

This supplement has been used in connection with the following health conditions:

Used for Why
1 Star
Refer to label instructions
Silicon is required in trace amounts for normal bone formation, and supplementation with silicon has increased bone mineral density in a small group of people with osteoporosis.
Silicon is required in trace amounts for normal bone formation,1 and supplementation with silicon has increased bone formation in animals.2 In preliminary human research, supplementation with silicon increased bone mineral density in a small group of people with osteoporosis.3 Optimal supplemental levels remain unknown, though some multivitamin-mineral supplements now contain small amounts of this trace mineral.
1 Star
Sprains and Strains
Refer to label instructions
Trace minerals, such as silicon are known to be important in the biochemistry of tissue healing.

Zinc is a component of many enzymes, including some that are needed to repair wounds. Even a mild deficiency of zinc can interfere with optimal recovery from everyday tissue damage as well as from more serious trauma.4 Trace minerals, such as manganese, copper, and silicon are also known to be important in the biochemistry of tissue healing.5 , 6 , 7 , 8 However, there have been no controlled studies of people with sprains or strains to explore the effect of deficiency of these minerals, or of oral supplementation, on the rate of healing.

How It Works

How to Use It

Because silicon has not been established as essential, a recommended intake has not been established. The average diet is estimated to provide 5–20 mg of silicon per day—an amount that appears adequate. When used as a supplement, common amounts range from 1 to 2 mg per day.

Where to Find It

Good dietary sources for silicon include whole-grain breads and cereals, root vegetables, and beer. A form of silicon called silicates is added to some processed foods.

Possible Deficiencies

Silicon is not an essential mineral. Deficiencies have not been reported.


Interactions with Supplements, Foods, & Other Compounds

At the time of writing, there were no well-known supplement or food interactions with this supplement.

Interactions with Medicines

As of the last update, we found no reported interactions between this supplement and medicines. It is possible that unknown interactions exist. If you take medication, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a supplement with your doctor or pharmacist.

Side Effects

Side Effects

A high dietary intake of silicon is not associated with any toxic effects. Inhalation of large amounts of silicon (in an industrial setting) can cause the respiratory disease silicosis.
