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