Calcium in biology

Calcium is a vital mineral in the body that helps build and maintain strong bones and teeth. It also plays a crucial role in muscle contraction, nerve signaling, and blood clotting. When your body needs calcium, it absorbs it from food sources like dairy, leafy greens, and fortified products. Proper calcium levels are essential for overall health, and imbalances can lead to issues like weak bones or muscle problems. In addition to supporting structural functions, calcium acts as a messenger inside cells, regulating various biological processes critical for your well-being.
