Calcium plays a critical role in various physiological processes, including bone health, muscle contraction, nerve function, and blood coagulation. The normal range for serum calcium is 8.5 to 10.5 mg/dL. Maintaining calcium levels within this range is vital to ensure optimal bodily functions and prevent complications such as hypocalcemia (low calcium levels) or hypercalcemia (high calcium levels).

Levels below 8.5 mg/dL can lead to muscle cramps, convulsions, and potential heart rhythm disturbances, while levels above 10.5 mg/dL may increase the risk of kidney stones, cardiovascular issues, and neuropsychiatric symptoms. Therefore, the maintenance of calcium levels within the 8.5 to 10.5 mg/dL range is essential for overall health and well-being.
