Calcium is a vital mineral  important for our body mainly for bone health.It also helps in blood clotting,helps in muscle contracting and helps nerves to send messages. Everyday we lose calcium through skin,hair,nails,urine,faeces and sweat. But our body cannot synthesise new calcium. So it is important to eat calcium containing foods as our body cannot synthesise calcium on its own.If we do not get necessary calcium,it is taken from our bones. Calcium gives strength and density to the bones, prevents bones from getting brittle and fragile leading to breakage and  forms strong and healthy teeth.

As age advances,people who do not have healthy bones may suffer from a condition called “Osteoporosis”.   Due to Osteoporosis bones weaken and become fragile which can lead to fracture at a later stage. It usually occurs in the spine, hip, arm and bones near the wrist. Consuming enough calcium and vitamin D is an important step in preventing and treating osteoporosis.
