Calcium (ca+)

Calcium is a vital macronutrient and electrolyte in the human body, primarily known for its essential role in bone and teeth strength, with over 99% of the body's calcium stored in these tissues. Beyond bone health, calcium also plays a critical role in muscle contraction, nerve transmission, blood clotting, enzyme activation, and as a second messenger in cellular signaling pathways. It is absorbed from the diet and regulated by hormones, with the skeleton acting as a calcium reservoir that constantly undergoes remodeling.
