Why is Calcium Important?
Calcium is a vital mineral crucial for numerous bodily functions, impacting everything from strong bones to heart health. Its importance stems from its multifaceted roles throughout the body.
Bone Health:
- Calcium is the primary building block for strong and healthy bones and teeth. Around 99% of the body's calcium resides in these structures.

Muscle Function:
- Calcium plays a critical role in muscle contractions, including those of the heart. This mineral facilitates the interaction of proteins within muscle cells, enabling movement. [Source: Better Health Channel, NHS] Without sufficient calcium, muscle function would be severely impaired.
Nerve Function:
- Calcium is also essential for nerve function, enabling communication between nerve cells and the transmission of nerve impulses. [Source: Better Health Channel] This process is vital for various bodily processes, including sensory perception and motor control.
Other Crucial Functions:
- Calcium contributes to healthy blood clotting. [Source: NHS]
- Some studies suggest potential links between adequate calcium intake (often combined with vitamin D) and a reduced risk of certain diseases, such as cancer, diabetes, and high blood pressure. [Source: Mayo Clinic] However, more research is needed to confirm these associations definitively.
Obtaining Sufficient Calcium
While calcium supplements can be helpful for individuals with deficiencies or specific needs, dietary intake is the primary and preferred method for obtaining sufficient calcium. [Source: Mayo Clinic] Good dietary sources include dairy products, leafy green vegetables, and fortified foods.
