what is the role of calcium in the teenage body
Calcium is a mineral that gives strength to your bones. Calcium is also necessary for many of your bodyâs functions, such as blood clotting and nerve and muscle function.During the teenage years (particularly ages 11-15), your bones are developing quickly and are storing calcium so that your skeleton will be strong later in life. Most basic multivitamin/mineral tablets have very little calcium in them. 2  Look for a calcium supplement that has vitamin D added. 3  Vitamin D helps your body absorb calcium. 4  Avoid âoyster shellâ or ânatural sourceâ calcium supplements.
