What is the role of calcium in the body?

Calcium plays a crucial role in the body, primarily associated with bone health and muscle function. It is one of the key components in the development and maintenance of strong bones and teeth. Adequate calcium intake helps prevent osteoporosis and ensures that bones remain dense and strong throughout life.

Additionally, calcium is essential for muscle contraction. It enables muscles to contract and relax properly, including the heart muscle, which is vital for maintaining a healthy cardiovascular system. Without sufficient calcium, muscle function can be impaired, leading to weakness and cramps.

While calcium has other roles, such as influencing blood clotting and signaling pathways in cells, its fundamental importance in skeletal integrity and muscle action underscores why it is often emphasized in discussions about micronutrients.
