Mineral important for bone, skin, hair, and nail health.
Also known as: Silica • Orthosilicic Acid
Overview
Silicon, often referred to as silica in its oxide form, is a trace mineral that plays a crucial role in the formation and maintenance of connective tissues. It is vital for collagen synthesis, which is essential for healthy skin, hair, nails, and bones. While not officially classified as an essential nutrient, a growing body of evidence supports its importance for health.
