Silicon is an essential trace element required for the normal growth, development, and integrity of hair, skin, nails, mucous membranes, arteries, bones, cartilage and connective tissue. Silicon is also involved in collagen formation, the fibrous protein matrix that provides support for tendons, ligaments, cartilage and bones.1,2  The best-documented function of silicon is its action in facilitating bone mineralization. While silicon is exceptionally well tolerated at high doses, scientists currently estimate the human requirement for silicon to be from 5 to 20 mg per day.
