Silica
Silica is a trace mineral essential for healthy skin, hair, nails, and connective tissue strength.
Silica is a trace mineral found in plants, water, and even the human body, known for its role in maintaining structural integrity. It supports the health of skin, hair, nails, and connective tissues like tendons and cartilage.
Often derived from bamboo or horsetail, silica is involved in collagen synthesis and may promote elasticity and strength in tissues. It also plays a minor role in bone mineral density and joint flexibility.
If you're looking to enhance your natural glow or support joint resilience, silica could be a helpful addition to your supplement routine. It's often included in beauty and bone health formulas.
Other names & forms of Silica supplement : silicon dioxide, orthosilicic acid, bamboo silica, horsetail extract
Possible Benefits
As a structural mineral, Silica provides benefits for connective tissues, bone matrix, and skin integrity:
- Skin, Hair & Nails: Often used to improve the appearance and strength of skin and hair, and to reduce brittleness of nails.
- Bone Health: Contributes to bone matrix formation and density, supporting skeletal health.
- Joint Support: May help maintain elasticity and resilience of joints and connective tissues.

Studies
These studies provide scientific insights into Silica benefits:
A 2019 open-label study in postmenopausal women found 20 mg/day silica from horsetail extract improved nail strength and skin elasticity over 90 days .
A 2022 RCT compared 30 mg/day bamboo-derived silica plus calcium vs. calcium alone in 100 adults and showed greater increase in bone mineral density at 6 months .
