Bone Defense formulas offer a variety of micronutrient profiles that allow scope for individualized nutritional support of bone health and maintenance. The foundation of each of these distinct formulas is choline-stabilized orthosilicic acid (ch-OSA®), a source of the mineral silicon. Silicon has been researched for its role in collagen synthesis and bone mineral density (BMD). By adding other bone-specific nutrients to the ch-OSA foundation, each Bone Defense formula is tailored to meet individual needs.*
