Silicic acid is the general name for a group of weak inorganic acids that are formed when silicon compounds react with water. It is slightly soluble in water and exists mainly in the form of hydrated forms or colloidal solutions. In nature, silicic acid is found in minerals, soils, natural waters and many plants, and its salts – silicates and silica – play an important role in geological processes and the structure of the earth’s crust.
The biological significance of silicic acid lies in strengthening connective tissues, bones, skin, hair and nails. Silicon participates in the synthesis of collagen, helps to maintain the elasticity of blood vessels and accelerates regeneration processes. Due to these properties, silicic acid is often included in cosmetics for skin and hair care, as well as dietary supplements aimed at strengthening the musculoskeletal system.
In medicine and pharmaceuticals, silicic acid is used in the form of its compounds, for example, as part of intestinal sorbents, which help to remove toxins and heavy metals from the body. It is also a critical component in the production of glass, ceramics, concrete, and other materials. While silicic acid is safe, a lack or excess of it in the diet can affect bone health, joint health, and skin health.
