Calcium is essential for human life. Apart frombeing a major constituent of bones and teeth,calcium is crucial for nerve conduction, musclecontraction, heartbeat, blood coagulation, theproduction of energy and maintenance of immunefunction, among other things. Severe calciumdeficiency may lead to abnormal heartbeat, dementia, muscle spasms and convulsions. Whendietary calcium is insufficient or serum calciumlevels drop, the body takes calcium from boneswhich can leave them weak and prone to fracture.
Vitamin D is required for calcium and phosphorusabsorption and utilization.
It is necessary forgrowth, and is especially important for normalgrowth and development of bones and teeth inchildren. Manganese is essential for protein andfat metabolism, healthy nerves, and healthyimmune system and blood sugar regulation. It isused for normal bone growth and reproduction.
