What is the most abundant mineral in the human body?

Calcium is recognized as the most abundant mineral in the human body, constituting about 1.5% of body weight. It plays a critical role in numerous physiological functions, including the formation and maintenance of bones and teeth, where approximately 99% of the body's calcium is stored. Additionally, calcium is vital for muscle contractions, blood clotting, and the proper functioning of the nervous system.

While other minerals like phosphorus, iron, and magnesium are important for overall health and play essential roles in various bodily functions, they do not exceed the abundance of calcium in the body. Phosphorus, for instance, is important for energy production and bone health, but it is found in lower amounts compared to calcium. Iron is crucial for oxygen transport in the blood, yet its total stored amount is significantly less than that of calcium. Magnesium plays key roles in hundreds of enzymatic reactions but is also much less abundant. Thus, calcium's prevalence in the body highlights its significant importance in maintaining health and supporting essential biological processes.
