D) Calcium is an essential mineral that plays a crucial role in bone health, muscle function, and nerve signaling. It is also involved in blood clotting and maintaining a regular heartbeat. A deficiency in calcium can lead to conditions such as osteoporosis, while excessive intake may cause hypercalcemia. Good dietary sources of calcium include dairy products, leafy green vegetables, and fortified foods. The recommended daily intake varies by age and gender, with adults generally needing around 1000-1200 mg per day. Calcium absorption is enhanced when consumed with vitamin D, and it is important to maintain a balanced diet to ensure adequate calcium levels.
