Ingredient Information
Summary
Silicon Dioxide, also known as silica, is a natural compound made of silicon and oxygen. It’s commonly found in nature as quartz and is a key component of sand. In the supplement industry, silicon dioxide is used as an anti-caking agent to prevent clumping and ensure even distribution of ingredients. It is also used in food production for similar purposes. Silicon dioxide is suitable for anyone looking to maintain the quality and consistency of powdered supplements or foods. Silicon dioxide is also believed to play a role in the formation of collagen and connective tissue, which supports bone mineralisation, skin elasticity, and hair and nail strength.

What Is Silicon Dioxide?
Silicon Dioxide, also known as silica, has the chemical formula SiO₂ and is sometimes referred to by its additive code E551. It is classified as a mineral compound and typically appears as a white, powdery substance. Silicon Dioxide is sourced from natural quartz or sand and can also be synthetically produced through chemical processes. It is commonly used in the food industry as an anti-caking agent to prevent clumping in powdered products. Additionally, it contributes to the normal maintenance of bones, skin, hair, and nails, highlighting its importance in various biological functions.
How It Works In The Body
Silicon dioxide (silica) is a natural compound that contributes to the normal formation of connective tissues, such as skin, hair, and nails. It helps maintain the structural integrity of these tissues by supporting collagen synthesis. While it’s not absorbed in large amounts, it plays a supportive role in overall tissue health.
Safety & Interactions
- Silicon Dioxide is generally recognised as safe when used as a food additive.
- There are no specific contraindications for Silicon Dioxide, but individuals with allergies to silica should exercise caution.
- The UK does not have a specific upper intake level for Silicon Dioxide, as it is considered safe at typical consumption levels.
- Excessive intake is unlikely through diet alone, but always adhere to recommended dosages in supplements.
Always consult your health practitioner before taking nutritional supplements, especially if you are taking medication or are under medical supervision. You should not take supplements as a substitute for a varied balanced diet or healthy lifestyle.
