Silica, a natural compound of silicon and oxygen, is available as a dietary supplement, often derived from plants or algae. It is primarily promoted for supporting bone, skin, hair, and nail health through its potential influence on collagen synthesis and mineral metabolism. While generally safe at recommended dosages, exceeding these may lead to minor gastrointestinal issues. It's crucial to distinguish dietary silica supplementation from the occupational hazard of silicosis, which results from prolonged inhalation of crystalline silica dust. Dietary supplements use amorphous silica which poses no such risk.
Key Information
Inside Body Harmful Score
Common Dosage
Typically ranges from 20-50mg daily, but can vary based on the specific silica source and intended use.
Source Type
natural
Production Process
Silica is extracted from natural sources such as plants (e.g., horsetail, bamboo), algae, and minerals. It can also be produced synthetically through various chemical processes.
Use Type
Inside BodyPotential Benefits
Enhances bone density, strength, and integrity by supporting bone formation, calcium absorption, and reducing age-related bone loss. Improves overall skeletal health and function, ultimately reducing the risk of fractures.
This benefit aims to improve overall skin health and appearance through increased hydration, reduced inflammation, improved elasticity, and protection from environmental damage. Healthy skin exhibits a smooth texture, even tone, and strong barrier function.
Silica may strengthen hair and nails by supporting keratin production, leading to thicker hair and stronger nails. It potentially reduces brittleness by improving the structural integrity of these tissues.
Possible Side Effects
Gastrointestinal discomfort includes nausea, bloating, and diarrhea, typically mild and transient. Symptoms are often dose-dependent and vary in severity.
Silicosis is a serious, irreversible lung disease caused by inhaling crystalline silica dust, leading to inflammation and scarring of the lungs. It is primarily an occupational hazard and causes impaired lung function.
Scientific Evidence
Studies investigating silica's role in collagen synthesis, bone mineralization, and connective tissue health. Further research is needed to confirm its efficacy in promoting skin, hair, and nail health. Sources for extraction methods and potential GI side effects with high dosages. Research distinguishing amorphous vs. crystalline silica effects is also relevant.
