What Is Calcium?
Calcium is an essential mineral that plays a vital role in building and maintaining strong bones and teeth. It also supports normal muscle contractions, nerve function, blood clotting, and heart rhythm. Because the body cannot produce calcium on its own, it must be obtained through food or supplements when recommended by a healthcare provider.
About 99% of the body’s calcium is stored in bones and teeth, where it provides strength and structure.
Why Calcium Matters
Adequate calcium intake helps maintain healthy bones throughout life and reduces the risk of osteoporosis and fractures as people age. Calcium is also essential for proper muscle and nerve function.
