OsteoStrong Fact Sheet: Silicon for Bone and Muscle Health


Silicon, a trace element found in the human body, is gaining recognition for its role in bone and muscle health. Though it is present in small amounts, its impact on the body’s musculoskeletal system is significant.

Silicon and Bone Health

Bone Formation and Development

  • Contribution: Essential for the growth and development of bones.
  • Collagen Synthesis: Aids in the formation of collagen, a key protein that provides structure and strength to bones.

Bone Mineral Density

  • Enhancement: Silicon contributes to increasing bone mineral density, vital for strong and healthy bones.
  • Osteoporosis Prevention: Its presence in the diet has been linked to a lower risk of osteoporosis and bone fractures.

Calcium Metabolism

  • Interplay with Calcium: Facilitates the body’s use of calcium, crucial for maintaining bone health.

Silicon and Muscle Health

Connective Tissue Strength

  • Support: Involved in the formation and maintenance of connective tissues in muscles including facia, tendon, and ligaments.
  • Flexibility and Elasticity: Contributes to the flexibility and resilience of muscle tissue.

Injury Prevention

  • Muscle Integrity: Supports muscle strength and integrity, potentially reducing the risk of injuries.

Dietary Sources of Silicon

  • Natural Sources: Abundant in whole grains, cereals, fruits, and vegetables, particularly in the outer layers of grains and in the husks of seeds.
  • Bioavailability: The bioavailability of silicon varies depending on the food source, with higher levels found in plant-based foods.

Silicon Deficiency

  • Impact: While outright deficiencies are rare, low levels of silicon may contribute to weaker bones and a higher risk of musculoskeletal disorders.
  • Signs: May include slower bone healing and decreased bone density.


  • Considerations: Silicon supplements are available, but their necessity is generally low given its presence in a balanced diet.
  • Consultation: Always seek advice from a healthcare professional before beginning any supplementation regimen.


Silicon plays a crucial role in maintaining bone and muscle health. It aids in the development and strength of bones and muscles. Moreover, silicon is believed to positively influence the metabolism of bone-forming cells, further supporting bone mineralisation, structure, and integrity. A diet rich in whole grains, fruits, and vegetables usually provides adequate silicon for the body’s needs. For those concerned about their silicon intake, professional guidance is recommended to determine the best approach for supplementation.
