Biosil by Natrol

• Biologically Active Silicon as choline-stabilized orthosilicic acid
• Beautifies Hair, Skin & Nails
• Essential for Collagen, Bones & Joints
• New! in a Bottle
• Dietary Supplement

Each capsule of patented BioSil contains 5 mg of silicon as choline-stabilized orthosilicic acid.
BioSil's Active Silicon is an essential partner of calcium for bones, glucosamine for joints, and antioxidants for healthier arteries and cardiovascular function.

The importance of Silicon
Silicon is a trace mineral required for the formation of healthy connective tissue, bone, skin, hair and nails. Silicon is essential for collagen formation, healthy arteries and regulates calcium deposition in bones.

Absorption is Key
Dietary sources of silicon such as those found in food, horsetail and colloidal gel (silica) products, are very poorly absorbed because of their insoluble, polymerized forms. For absorption to occur, dietary silicon must be first converted to Orthosilicic Acid (monomeric silicic acid), the bioavailable form found by Biosil

Why is BioSil Different?
BioSil (Si[OH]4) is 20,000 times more soluble than silica (SIO2 - found in horsetail and colloidal gels) and 2.5 times more bioavailable than other forms of silicon!

The superiority of silicon as concentrated, choline-stabilized orthosilicic acid from BioSil has been proven in a peer-reviewed scientific study comparing three different forms of silicon. The results of the comparative, cross-over, double blind clinical trial demonstrated that the stabilized monomeric form of silicon (stabilized-orthosilicic acid-as found in Biosil) is far superior to colloidal silica and horsetail extract. In fact, of the three experimental groups, only BioSil offered a bioavailable source of silicon: the other forms of silicon (horsetail and colloidal gel) were no better than placebo.
