Silica

Silica is a trace element naturally present in the body, particularly in connective and supportive tissues such as bones, cartilage, tendons, skin, hair, and nails. It is also found in the diet, notably in whole grains, certain vegetables, and mineral water, although intakes vary considerably depending on eating habits. At a biological level, silica plays a role in the synthesis of collagen and elastin, two structural proteins essential to the strength and elasticity of connective tissues. It thereby contributes to maintaining bone resistance and cartilage integrity. Scientific studies also suggest it is involved in the health of skin, hair, and nails by supporting their structural framework. Silica concentrations in the body tend to decrease with age, which may justify an interest in supplementation. It is commonly offered in the form of organic silica or silicon dioxide, forms valued for their bioavailability. A supplementary intake may contribute to preserving supportive tissues as part of an overall nutritional approach.
