 Reliable
and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies
suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal
or no scientific evidence. For a supplement, little scientific support and/or minimal health
benefit. |

Who is likely to be deficient?
Silicon is not an essential mineral. Deficiencies have not been reported.
How much is usually taken?
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.
Are there any side effects or interactions?
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.
At the time of writing, there were no well-known drug interactions with silicon.
