Silica WHAT IS SILICA? SILICA (also known as silicon dioxide) is the second most abundant element on earth and the third most abundant trace element in the human body after iron and zinc. It is essential to human health and is required for the development of strong bones, cartilage, connective tissue, skin, hair, and nails. An interesting feature of silica is its unique ability to boost our production of bone-building cells (osteoblasts) while reducing the number of cells that break down and compromise the strength of our bones (osteoclasts), so naturally helps improve bone mineral density. #silica #silicasupplements Visit us at https://www.nationalnutrition.ca/minerals/single-minerals/silica.html
