Introduction

Silicon is a trace mineral involved in the formation and maintenance of connective tissues, including bones, skin, hair, nails, and blood vessels. It supports collagen synthesis and helps improve the utilization of minerals such as calcium and magnesium.

What Is Silicon?

Silicon is a naturally occurring trace element found primarily in plant-based foods and drinking water.

• Type: Trace mineral
• Main role: Connective tissue and bone support
• Storage: Bones, skin, hair, nails, and connective tissues

How Silicon Works in the Body

Silicon contributes to structural integrity by supporting collagen and elastin formation.

• Supports collagen synthesis
• Enhances bone mineralization
• Improves utilization of calcium and magnesium
• Supports skin elasticity and hair strength

Sources of Silicon

• Whole grains (oats, barley)
• Brown rice
• Bananas
• Green beans
• Root vegetables
• Mineral-rich drinking water

Silicon Deficiency

Silicon deficiency is not well defined but low intake may affect connective tissue and bone health.

Possible deficiency-related effects include:

• Weaker bones
• Brittle hair and nails
• Reduced skin elasticity
• Delayed wound healing

Dosage & How to Take Silicon

• Typical intake: 20–50 mg/day (from diet)
• Common supplement dose: 5–20 mg/day
• Upper limit: Not clearly established

Silicon supplements are often taken once daily, preferably with meals.

Forms of Silicon

• Orthosilicic acid
• Choline-stabilized orthosilicic acid (ch-OSA)
• Silica (silicon dioxide)
• Plant-based silicon extracts

Benefits & Uses

• Supports bone strength and density
• Improves skin elasticity and texture
• Strengthens hair and nails
• Supports joint and connective tissue health
• Enhances mineral metabolism

Safety, Side Effects & Precautions

• Generally safe at dietary and supplemental levels
• Excess intake from supplements is uncommon
• Avoid inhalation of silica dust (occupational hazard)
• Use supplements as directed

Special Populations

• Postmenopausal women: Supports bone and skin health
• Elderly: May help maintain connective tissue integrity
• People with brittle hair/nails: Often benefit from adequate intake
• Athletes: Supports joint and tissue resilience

Frequently Asked Questions
