In essence, bones are actually made out of calcium. Specifically, they are made of hydroxylapatite, a compound of calcium with phosphorus, oxygen, and hydrogen. Hydroxylapatite, Ca10(PO4)6(OH)2, is the mineral portion of bones and teeth, so your body needs calcium in order to build strong bones. Osteoporosis, frailness of the bones, is caused by low mineral density, so having enough calcium in your diet really is critical.
