Silicon
Looking to buy silicon? Silicon is an element that occurs naturally in the earth, in food and, in small amounts, in the human body. It is also referred to as silicon or silicon dioxide, depending on the form in which it occurs. On this page, you can read about what silicon is, where it is found and the forms it takes.

What is silicon?
Silicon is a chemical element with the symbol Si. It is one of the most abundant elements on earth and is mainly found in minerals and rocks.
In nature, silicon rarely occurs in its pure form. It is usually bound to oxygen, forming compounds such as silicon dioxide, better known as silica. This form is found in sand, quartz and clay, among other things.
Alongside these inorganic forms, there are also soluble forms of silicon that occur in small amounts in food and water.
Silicon in food
Silicon occurs naturally in various foods. Plant-based foods are the main source of silicon. These include wholegrains, vegetables and certain fruits such as apples, bananas, grapes and citrus fruits.
Foods such as nuts, seeds and root vegetables also naturally contain silicon. The amount can vary from one product to another and depends on factors such as soil quality and food processing.
The composition of silicon
When we talk about silicon in food or supplements, we usually mean compounds in which silicon is bound to other elements. One well-known form is silicon dioxide, but soluble forms such as orthosilicic compounds also exist.
These compounds differ in structure and solubility. This means that silicon does not have one fixed form, but occurs in different compositions.
Our silicon products contain the mineral in a pure, bioavailable form. The capsules are plant-based and free from artificial additives. The liquid forms contain a silicon solution in purified water, without preservatives.
What forms does silicon take?
In nature, silicon almost always occurs in combination with other elements. It is found in sand, rock and clay, for example, where it occurs as silicon dioxide (silica). This is the most common form on earth.
Alongside these solid forms, there are also soluble forms of silicon, such as orthosilicic acid. These occur in small amounts in food and drinking water. These are the forms that are relevant when we look at silicon in food and supplements.
Silicon is used in supplements in various forms, such as liquid silicon (silicon drops) or silicon tablets. The form used varies from product to product.
How is silicon absorbed from food?
You consume silicon every day through food and water, often without realising it. Plant-based foods in particular, such as grains and vegetables, naturally contain small amounts of silicon.
The exact amount can vary. This depends, among other things, on how a product is grown, processed and prepared. Unprocessed foods often contain different amounts from highly processed products.
The form in which silicon occurs also plays a role. Some forms are more soluble than others.
Eating a varied diet makes you more likely to consume a range of natural sources of silicon.

Silicon is a chemical element that occurs naturally in the earth. It is found in sand, rock and, in smaller amounts, in food and water. The symbol for silicon is Si.
Silicon occurs naturally in various foods. Plant-based foods in particular, such as whole grains, vegetables, fruit, nuts and seeds, contain small amounts of silicon.
Silicon dioxide, also known as silica, is a compound of silicon and oxygen. It is the most common form of silicon in nature and is found in sand, quartz and clay, among other things.
Silicon is a naturally occurring element (Si), while silicone is a synthetic material made from silicon. Silicone is often used in industrial applications such as seals and coatings.
Liquid silicon, also known as silicon drops, is a form of silicon dissolved in water. This type of supplement is often chosen because it is easy to use.
Silicium is generally used at the recommended supplement dosages. As with any supplement, it is important to follow the directions for use. Unsure whether to take it? Speak to a healthcare professional.
If you want to buy silicon, it is worth checking the product's purity, composition and the form it comes in. Where possible, choose a product without unnecessary additives.
- Fat-soluble vitamins (A, D, E, K): Take with a meal containing fat.
- Water-soluble vitamins (C, B-complex): Can be taken at any time of the day. B12 is best absorbed on an empty stomach.
When combining supplements, it is important to follow the recommended daily dose for each product and avoid an excessive total intake of certain vitamins or minerals.
Everyone responds differently to supplements. Interactions between different food supplements are also possible. You use and combine supplements at your own responsibility. If you are unsure about combining different food supplements, we recommend consulting a professional.
Pay attention to how your body responds when taking supplements, and consult a doctor or pharmacist if you are taking medication, are pregnant or breastfeeding, or have a medical condition.
