Calcium is the essential mineral for creating strong bones. It plays a vital role in bone development and maintenance throughout a person’s life. Calcium provides structural support to bones, ensuring they remain dense and healthy. The body requires adequate calcium intake, especially during childhood and adolescence when bones are growing rapidly. If dietary calcium is insufficient, the body may leach calcium from bones, leading to weakened bone structure and conditions such as osteopenia or osteoporosis later in life. Sources of calcium include dairy products, leafy green vegetables, nuts, and fortified foods.
