What is silicon dioxide? (+Frequently asked questions)

Why We Use Silicon Dioxide in Some Products

Z Natural Foods is dedicated to maintaining the highest standards of transparency and quality in our diverse range of all-natural products. We take great pride in sourcing premium, natural ingredients, ensuring that our customers receive products characterized by purity, freshness, and cleanliness.

Our commitment to quality extends to providing comprehensive documentation for all our offerings. This includes detailed information regarding ingredients, country of origin, and Certificates of Analysis (CoAs) for each product. Moreover, we meticulously archive batch lot numbers to ensure traceability and consistency in every purchase.

Silicon dioxide exists naturally within the earth and our bodies.7

A notable aspect of our product range is the judicious use of natural silicon dioxide, a component often misunderstood in the natural foods industry. Silicon dioxide, a naturally occurring compound composed of silicon (Si) and oxygen (O2), forming SiO2, is abundant both within the Earth's crust and the human body. It serves as a crucial anti-caking agent, widely utilized to prevent the clumping of natural, raw materials, thus preserving the integrity and usability of our products.

For instance, our popular Organic Freeze-Dried Blackberry Powder contains a minimal necessary amount of silicon dioxide. This inclusion is pivotal in ensuring the powder remains free-flowing and easy to use. Without the careful integration of this anti-caking agent, the product could solidify, significantly hindering its practicality and usability. Our addition of silicon dioxide, therefore, is essential for maintaining the product's ease of use, allowing for effortless incorporation into smoothies, yogurts, or as a nutritious topping on various foods.

Silicon Dioxide is a trace mineral necessary for healthy bones, skin, hair, and nails -- found naturally in many plant foods

Silicon, a trace mineral, plays a pivotal role in various physiological functions within the human body. It is found in numerous structures including blood vessels, cartilage, tendons, bones, collagen, and skin. Advanced scientific research highlights its significant presence in the aorta, underscoring its importance in vascular health.8

Beyond common perceptions, Silicon collaborates with Nitric Oxide (NO) in maintaining arterial health. This synergy is crucial for preserving the elasticity of blood vessel walls, a vital factor in preventing the permeability of these walls to fatty deposits and calcium – key contributors to plaque formation. This elasticity is instrumental in cardiovascular health, positioning Silicon as an increasingly recognized nutrient in cardiovascular nutrition research.8

Contemporary studies indicate a decline in tissue Silicon levels with aging. A deficiency in Silicon is characterized by symptoms such as dry and brittle hair, brittle nails, suboptimal skin quality, inefficient calcium utilization, and potential arterial diseases. Furthermore, research suggests that Silicon supplementation can significantly enhance collagen synthesis in growing bones.

The recommended daily intake of Silicon for adults ranges between 200 to 500 mg. This intake is crucial for maintaining the structural integrity and functionality of various bodily tissues.

When necessary, Z Natural Foods uses minimal amounts of silicon dioxide while never exceeding 2% of the weight of the food (often using just a fraction of this amount).

At Z Natural Foods, we conscientiously utilize Silicon dioxide in minimal quantities, ensuring it never exceeds 2% of the total weight of the food product, often utilizing merely a fraction of this amount. Our approach aligns with the acceptable use guidelines set forth by the United States Food & Drug Administration (FDA)4 and the World Health Organization (WHO)5. We are committed to maintaining the natural integrity of our food products while ensuring compliance with global health standards.

Silicon Dioxide is naturally found in fruits, vegetables, garlic, and even dark greens

Additionally, this essential trace mineral is naturally found in fruits, vegetables, nuts, grains, and seeds, as well as herbs such as parsley, garlic, and horsetail. Horsetail, in particular, is a common ingredient in hair, skin, and nail products because of its high content of silicon dioxide.

The fruits and vegetables that rank the highest in this amazing trace mineral include grapes, oranges, apples, cherries, plums, artichokes, beans, peas, asparagus, beet, celery, cucumbers, lettuce, radishes, onions and dark greens of all kinds.

Silicon Dioxide is a prevalent mineral found in a wide variety of foods and is safe and may be essential to our health

Understandably, many of our customers come to us confused and misinformed. In many cases, the information found on the internet is questionable and may not be accurate or current.

We urge you to do your own research from reputable sources and obtain the most reliable information about the products you consume. Z Natural Foods is proud of our transparency policy and are happy to provide you with up-to-date information on any of our products and even its particular ‘batch lot number’.

As always, we welcome your questions and inquiries.

FAQ: Frequently Asked Questions

What is Silicon Dioxide? 

Silicon dioxide, or silica (SiO2), is a compound of silicon and oxygen, constituting 59% of the Earth's crust and a key component in most rocks. Found in nature, it is vital in various ecosystems.

In the food and supplement industry, SiO2 is used as an anti-caking agent to improve texture and shelf life. The United States Food and Drug Administration (FDA) classifies it as Generally Recognized as Safe (GRAS) when used in small quantities, recommending a maximum of 2% of daily food intake, or about 10-30 grams.

Silicon dioxide exists in two primary forms: crystalline silica and amorphous silica, each with unique properties relevant to their use and safety. Ongoing research and quality control, supported by scientific communities and regulatory bodies like the FDA and World Health Organization (WHO), ensure safe and effective use of SiO2 in products. For comprehensive information, authoritative sources such as the FDA, USDA, and the Mayo Clinic Research Information Center offer detailed insights.

Is Silicon a natural ingredient? 

Silicon, a trace mineral naturally occurring as silicon and oxygen, is characterized by strong covalent bonds in its atomic structure. It predominantly exists in combined forms like silicon dioxide in sand, quartz, crystal, and silicates in granite, mica, and clay, illustrating its widespread presence in the Earth's crust.

Dietarily, silicon dioxide is found in foods such as rice, beans, leafy greens, and root vegetables. This highlights its nutritional relevance, contributing to the dietary intake of silicon. The herbal supplement industry also utilizes silicon-rich herbs like horsetail, nettle, and oat straw, especially in calcium-enriched products, showcasing its utility in natural health products.
