Calcium is a vital mineral essential for numerous biological functions in the human body. It is the most abundant mineral in the body, primarily found in bones and teeth, providing strength and structure. Calcium also plays a crucial role in muscle contraction, blood clotting, nerve signaling, and maintaining a steady heartbeat.

It is naturally found in dairy products like milk, cheese, and yogurt, as well as leafy green vegetables, nuts, and fortified foods. The recommended daily intake varies by age, but adequate calcium consumption is necessary to prevent osteoporosis, a condition that weakens bones.

The body requires vitamin D to absorb calcium efficiently. A deficiency can lead to weak bones, muscle cramps, and an increased risk of fractures. While calcium supplements are available, it is best to obtain this mineral through a balanced diet. Maintaining proper calcium levels supports overall health and well-being.
