Calcium plays a vital role in the body beyond just bone health. It is essential for processes such as muscle contraction, blood clotting, and the functioning of nerves. Calcium helps maintain normal heart rhythm and facilitates effective communication between nerves and muscles, contributing to overall physiological function. Additionally, adequate calcium intake may lower the risk of certain diseases, such as osteoporosis, and support metabolic processes. Overall, calcium is a crucial mineral for maintaining several systems in the body beyond skeletal health.
