Which mineral is the most abundant in the human body?

Calcium is the most abundant mineral in the human body, constituting a critical component of bones and teeth. Approximately 99% of the body’s total calcium is stored in these structures, providing structural integrity and strength. Beyond its role in skeletal health, calcium is essential for various physiological functions, including muscle contraction, neurotransmitter release, and blood coagulation.

This mineral helps maintain cellular function and is involved in numerous metabolic processes. The body's calcium levels are tightly regulated by hormones like parathyroid hormone and calcitonin to ensure adequate levels are available for these functions while maintaining bone density. Understanding the role of calcium highlights its importance in overall health, particularly in terms of skeletal integrity and metabolic processes.
