When people think of bone health - calcium is the first mineral that might spring to mind. However, there are more minerals that are needed for bone health than just calcium. Many trace minerals such as copper, manganese, zinc and boron are also important, as is vitamin K1 and vitamin D. Bone is a dynamic, living tissue that is constantly being broken down and rebuilt, even in adults. Not many people think about looking after their bones until they start to break down as in arthritis or osteoporosis. However, there is lots you can do to ward off oesteoporosis, which is where there is more bone breaking down than being formed.
