Many people think that when people grow old, back pain and leg and foot pain are caused by “calcium deficiency”, and they even think that this kind of pain does not need to be treated, and that they can get over it if they can stand it. Generally speaking, once osteoporosis symptoms are obvious, the amount of bone in the bones has already been lost by more than 30%-50%. At this time, bone destruction is greater than the production of new bone, the minerals in the bones are reduced, and the bone trabeculae in the bones become thin and brittle or fracture, resulting in the above symptoms. At this time, the effect of taking calcium alone is often less than ideal, and requires comprehensive treatment of the imbalance of bone metabolism, not only to promote bone production, but also to stop bone loss, so as to effectively control osteoporosis.
