Bone is hard, dense, calcified, living tissue. Bone serves as a framework for the attachment of muscles and helps to protect the vital organs, such as the brain. It also contains large amounts of calcium, a mineral that is essential for the cell function. In our thirties we reach our optimal bone mass before the production of new cells slows down, leading to our bones losing density as we grow older. Puravits offer a wide range of vitamins to help maintain healthy bones.
