New Roots Herbal Silica Liquid is a rich and bioavailable source of the mineral necessary for the body to manufacture key structural proteins that include keratin and collagen. These proteins provide the strength and flexibility for healthy hair from root to tip; strong nails; and youthful-looking, supple skin. The benefits of silica supplementation are not limited to outward appearance: silica also helps form the matrix of connective tissue responsible for the elasticity of blood vessels as well as for the strength and flexibility of tendons, ligaments, and cartilage.
