An estimated 72% of dietary calcium in the United States and Canada comes from dairy products like milk, cheese, and yogurt. This highlights the importance of understanding what are the food sources of calcium ions to maintain proper intake for bone health and vital physiological functions. Sourcing this essential mineral from a balanced diet is crucial for people of all ages.

Approximately 99% of the body's calcium is stored in the bones and teeth, but the remaining 1% circulates in the blood and is critically involved in many physiological processes. Among its most vital functions, calcium ions ($Ca^{2+}$) are required for normal blood clotting. Without a sufficient supply of these ions, the complex cascade of events that leads to the formation of a stable blood clot would be severely impaired, risking excessive bleeding.

Over 99% of the body's total calcium is stored in bone, forming a vital reservoir that provides both structural integrity and a source of ions for biological processes. Understanding what stores and releases calcium ions is crucial for comprehending fundamental cellular functions like muscle contraction, nerve signaling, and hormone regulation.

According to a study published in *Nature*, calcium ions (Ca²⁺) play a pivotal role beyond just bone health, serving as key regulators of muscle function and growth. These ions act as versatile intracellular signals, dictating everything from muscle contraction to the complex processes that drive lasting muscle growth.

According to the National Institutes of Health, skeletal muscle makes up about 40% of the human body's weight. At a cellular level, the essential process that plays a key role in the contraction of muscles relies on a precise choreography of molecules, primarily involving calcium ions and the energy-carrying molecule ATP.
