How does calcium help in the health of the body?  

Hi mayank.calcium is really good for healthy bone. But only intaking calcium wont help you because inorder to fix calcium it needs vitamin D.Without vitamin D it cannot fix.Hence you should also take care of vitamin D.The best source of vitamin D is sunlight.
