                                An average adult human body is composed of approximately 1–2% calcium by weight, making it the most abundant mineral. The vast majority of this calcium, over 99%, is stored within our skeletal system, providing the fundamental structure for our bones and teeth. Its significance, however, extends far beyond bone structure, influencing a wide range of critical physiological processes.
