Nutritional Supplement

Silicon

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.

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.
