Why do bones need calcium?

ANSWER

Getting enough calcium is important for keeping your bones strong throughout your lifetime, but especially during childhood, while the bones are still growing. It's also essential during the senior years, when bones start to break down faster than they can rebuild. Older bones become more brittle and easily fractured -- a condition called osteoporosis.
