Silica

Within the world of micronutrients, elements like iron and magnesium often take center stage. However, there's a mineral that follows these well-known substances in terms of abundance in our bodies, yet often remains under-researched: silicon. This element, commonly found in nature as silica (silicon dioxide), is an essential component of our physical architecture.

For those who strive for a conscious lifestyle, insight into the body's structural integrity is crucial. As we age, the natural presence of silicon in our tissues gradually decreases. This increases the relevance of this trace element for supporting connective tissue structures and the body's overall vitality. In this article, we delve into the biological processes involving silicon, using clinically sound methods.

What is silicon and how does it work in the body?

Silicon doesn't occur naturally in its pure form, but is always bound to oxygen, which we know as silica or silicon dioxide. In the human body, this mineral is concentrated specifically in tissues that require structure, elasticity, and strength. These include bones, cartilage, tendons, skin, hair, and nails.

The most bioavailable form for humans is orthosilicic acid (OSA). This is the soluble form of silica that can be efficiently absorbed by the body and transported to its target tissues. In these tissues, silicon plays a fundamental role in the synthesis of collagen and glycosaminoglycans. These are the essential building blocks responsible for the strength of our connective tissue matrix.

Structural support: Bones and connective tissue

One of silicon's most crucial functions is its role in bone homeostasis. This trace element is present in high concentrations in areas where active bone formation is taking place. Here, it contributes to the mineralization of the bone matrix, a process by which bone acquires its required density and hardness.

Scientific insight suggests a synergistic effect between silicon and calcium. While calcium primarily provides the skeleton's hardness, silicon supports flexibility through its involvement in the formation of type I collagen. This is essential for maintaining strong and resilient structures, especially with age when bone mineralization naturally changes.

Personal Care Application: Skin, Hair & Nails

The presence of silicon in the dermis is directly related to the quality of the extracellular matrix. Collagen, supported in part by silicon, helps the skin maintain its elasticity and hydration. A decrease in silicon levels in the tissues can cause the skin to lose its elasticity.

This trace element is also important for the keratin structures in our body:

Hair: Silicon contributes to the strength of the hair shaft. Optimal silicon levels in the hair follicle are associated with healthy shine and reduced hair breakage.
Nails: Because nails are largely composed of minerals, silicon is one of the dominant elements in healthy nail plates. It supports hardness and helps prevent nails from becoming brittle.

Dietary sources and bioavailability

Although silicon is abundant in the Earth's crust, its actual absorption from food depends heavily on its chemical form. Our modern diet, due to intensive agriculture and industrial processing, is often poorer in available forms of silicon than was historically the case.

Important dietary sources of silicon are:

Whole grains: Oats, barley and millet in particular contain significant amounts.
Vegetables: Think green beans and leafy greens.
Drinking water: Water from natural sources often contains dissolved orthosilicic acid, which is the most absorbable form.

It's important to note that silica in solid plant foods is less easily absorbed than water-soluble varieties. For individuals who don't get enough through their regular diet, a targeted supplement can offer a discreet and effective solution.

Quality and formulation

When choosing additional support, the specific form of silicon is crucial for its effectiveness. Many conventional supplements use forms that the body struggles to process. Formulations based on stabilized orthosilicic acid are preferred due to their superior bioavailability. Furthermore, natural plant extracts such as bamboo and horsetail are known for their exceptionally high content of organically bound silicon.

Summary

Silicon is a vital building block for the structural integrity of the human body. From the mineralization of our bones to the elasticity of our skin and the strength of our hair and nails, this trace element plays a vital role in the connective tissue matrix. By making conscious choices in nutrition and supplementation, you support your physical constitution at its very core.

Frequently Asked Questions (FAQ)

Is silicon the same as silicone? No, silicon is a naturally occurring mineral element. Silicones are synthetic polymers used in industrial and cosmetic applications. This article focuses exclusively on the natural trace element silicon.

At what age is silicon supplementation relevant? The body's natural silicon reserves decrease with age, often noticeable from the age of thirty onward. From this age onward, paying extra attention to this trace element can be beneficial for maintaining tissue strength.

Can I combine silicon with other minerals? Yes, silicon combines well with other nutrients such as calcium, magnesium, or zinc. There are no known clinical contraindications for concurrent use with regular vitamin supplements.

What is the best form of silicon for absorption? Orthosilicic acid (OSA) and natural plant extracts from bamboo or horsetail are considered the most effective forms for absorption by the human body.
