Bones do not become brittle after taking too many calcium tablets. The human body is a particularly sophisticated system, for the body fluids within the ion control is very fine, once the calcium tablets to eat more, into the blood of calcium ions increased, the body will automatically change the secretion of hormones, especially the parathyroid hormone secretion, the role of excess calcium ions excreted, and will not be too much deposition to the bone. Therefore, even if the intake of calcium tablets is too much, it will not cause the bones to become brittle, but will maintain a relatively stable balance of calcium ions in the bone and blood under the action of the body, and will not cause significant changes in the bone and blood.
